Outline the two-factor theory of maintenance of classically conditioned associations e.g. fear
Trauma (UCS) and needle (CS)-> fear response (UCR) Avoid injections-> fear reduced-> tendency to avoid is reinforced
26
What is Thorndike's Law of Effect?
A response followed by a satisfying consequence will be more likely to occur A response followed by an aversive consequence will become less likely to occured
27
What is operant conditioning maintained by?
The consequences after behaviour is learned
28
What is positive reinforcement in operant conditioning?
Occurs when a response is strengthened by the subsequent presentation of a reinforcer Can be primary or secondary reinforcers
29
What is a primary reinforcer in positive reinforcement?
Those needed for survival e.g. food, water, sleep, sex
30
What is a secondary reinforcer in positive reinforcement?
Stimuli that acquire reinforcing properties through their association with primary reinforcers e.g. money and praise
31
What is negative reinforcement in operant conditioning?
Occurs when a response is strengthened by the removal (or avoidance) of an aversive stimulus
32
What is a negative reinforcer?
The aversive stimulus that is removed or avoided (e.g. the use of painkillers are reinforced by removing pain)
33
Does 'positive' and 'negative' refer to 'good' and 'bad' stimuli?
NO!! | Refers to presentation or removal of a stimulus
34
What is a positive punishment?
Occurs when a response is weakened by the presentation of a stimulus (e.g. squirting a cat with water when it jumps on dining table)
35
What is a negative punishment?
Occurs when a response is weakened by the removal of a stimulus (e.g. phone confiscated)
36
Which has a more potent influence on behaviour (according to Skinner)- reinforcement or punishment?
Reinforcement is a much more potent influence on behaviour than punishment Largely because punishment can only make certain responses less frequent- you can't teach new behaviour
37
What is operant extinction?
The weakening and eventual disappearance of a response because it is no longer reinforced
38
What is resistance to extinction?
The degree to which non-reinforced responses persist
39
What types of reinforcement schedules in operant conditioning are there?
Fixed interval schedule Variable interval schedule Fixed ration schedule Variable ration schedule
40
What is a fixed interval schedule in reinforcement?
Reinforcement occurs after fixed time interval
41
What is a variable interval schedule in reinforcement?
Time interval varies at random around an average
42
What is a fixed ratio schedule in reinforcement?
Reinforcement is given after a fixed number of responses
43
What is a variable ratio schedule in reinforcement?
Reinforcement is given after a variable number of responses (all centred around an average)
44
What produces more rapid learning- continuous or partial reinforcement?
Continuous reinforcement produces more rapid learning Association between a behaviour and its consequences is easier to understand
45
What reinforced responses extinguish more rapidly- continuous or partial reinforcement?
Continuously reinforced responses extinguish more rapidly The shift to no reinforcement is sudden and easier to understand
46
How does operant conditioning relate to medicine (e.g. with chronic pain behaviour)?
Chronic pain behaviour includes limping, grimacing, and medication requests Reinforced by family or staff e.g. by being overly sympathetic, encouraging rest, increasing medication Behaviour is reinforced by gratitude signals from the patient A cycle is created in which the patient receives positive consequences for "being in pain" so pain is more likely to occur in frequency
47
What is the cognitive approach?
Bandura's belief that humans are active info processors and think about the relationship between behaviour and consequences Social imitation may hasten or short-cut the acquisition of new behaviours without the necessity of reinforcing
48
What is Bandura's Social Learning Theory?
Observational (vicarious) learning= observe others and see consequences of their behaviours Vicarious reinforcement= if their behaviours are reinforced we tend to imitate the behaviours
49
What is modeling/observation learning (Bandura)?
Occurs by watching and imitating actions of another person or by noting consequences of a person's actions
50
What are the steps to successful modelling in observational learning?
Pay attention to model Remember what was done Must be able to reproduce modeled behaviour If successful or behaviour is rewarded, behaviour more likely to recur
51
Outline Bandura's Bobo Doll Experiment (1961)
72 children (approx 4y old) spent time in playroom with adult who modelled either non-aggressive or aggressive play Then spent 20 mins alone in room Aggressive behaviour was imitative
52
In social learning, we don't imitate the behaviour of everyone we encounter. Imitation is more likely if model is...
Seen to be rewarded High status (e.g. medical consultant) Similar to us (e.g. colleagues) Friendly (e.g. peers)
53
What are the 5 modern day killers?
``` Dietary excess Alcohol consumption Lack of exercise Smoking Unsafe sexual behaviour ```
54
Define health behaviour
Any activity undertaken by an individual believing himself to be healthy for the purpose of preventing disease or detecting it at an asymptomatic stage
55
What is the Alameda study?
Alameda county CA List of 7 health behaviours they selected what they did.... not smoking, eating breakfast, not snacking, regular exercise, getting 7-8 hrs sleep, moderate alcohol, moderate weight After 10 years, lower mortality in individuals (1/4) who practised all 7 than those who practises <3
56
What are the categories of behaviour change interventions?
Population Individual Community
57

Change 4 life
58
Outline the study of smoking education in school (Nutbeam et al, 1993)
Education programme (specially trained teachers over 3 months) about effects of smoking in 39 schools in England and Wales Self report questionnaire and saliva test before, immediately after and at 1 year follow up
59
How can health education be enhanced?
Info is most effective for discrete behaviours (e.g. getting child vaccinated) Messages tailored to a particular audience (e.g. suggesting condom use to sexually active teens better than abstinence) Need more than knowledge- e.g. social and psychological support or skills to change
60
What are the cues for unhealthy eating (learning theory)?
Visual (e.g. fast food signs, sweets at checkout) Auditory (e.g. ice cream bell) Olfactory (e.g. smell of baking bread) Location (e.g. the couch or car) Time (e.g. evening)/ Events (e.g. end of TV programme ) Emotional (e.g. bored, stressed, sad, happy)
61
What are the reinforcement contingencies in unhealthy eating?
POSITIVE REINFORCEMENT Dopamine, filling an empty void/boredom Praise for preparing a high-fat meal for the family NEGATIVE REINFORCEMENT Avoid painful emotions by comfort eating PUNISHMENT Preparing a low fat meal is criticised DELAYED (LIMITED) POSITIVE REINFORCEMENT FOR HEALTHY EATING Efforts at dietary change/weight loss go unnoticed by others Avoiding future health problems is too remote
62
What behaviour modification techniques techniques can be used in unhealthy eating?
STIMULUS CONTROL TECHNIQUES Keep ‘danger’ foods out of the house Avoid keeping biscuits in the same cupboard as tea & coffee Eat only at the dining table Use small plates Do not watch TV at the same time as eating COUNTER CONDITIONING Identify ‘high-risk’ situations/cues (e.g. stress) and ‘healthier’ responses EXAMPLES OF CONTINGENCY MANAGEMENT Involve significant others to praise healthy eating choices Plan specific rewards for successful weight loss Vouchers for adherence to healthy eating ad weight loss NATURALLY OCCURRING REINFORCERS Improved self-esteem (positive reinforcement) Reduction in symptoms of breathlessness (negative reinforcement)
63
Are incentives used in smoking cessation schemes more effective than those aimed at weight loss?
Yes Incentives used in smoking cessation schemes were most effective those aimed at weight loss were the least effective NB. Very successful scheme in Dundee offered cash to expectant mothers
64
What are the limitations of reinforcement programmes?
Lack of generalization (only affects behaviour regarding the specific trait that is being rewarded) Poor maintenance (rapid extinction of the desired behaviour once the reinforcer disappears) Impractical and expensive
65
Does fear arousal work? (Janis & Fesbach, 1953 dental health)
Dental health teaching Low, moderate and high fear-inducing lectures given to different groups Effect on subsequent dental hygiene behaviour was measured with self-report questionnaires 1 week later High levels of fear-> denial and avoidance behaviour (Low levels better)
66
What are the largest influencers on adolescent smoking? (Kobus, 2003)
Best friends have greatest influence Then peer groups There is substantial peer group homogeneity with respect to adolescent smoking
67
How did the Waterloo Smoking Prevention Project work and why was this effective? (Flay et al, 1983)
High school students given 6 sessions including rehearsing skills to build confidence in ability to resist peer pressure to smoke Practical skills useful Reduced number of children starting smoking
68
What is the expectancy-value principle?
The potential for a behaviour to occur in any specific situation is a function of the expectancy that the behaviour will lead to a particular outcome and the value of that outcome
69
What does Rosenstock's Health Beliefs Model (1966) show?
The likelihood of behavioural change ``` As a result of: Perceived threat Cues to action Background variables Perceived susceptibility/seriousness Perceived benefits/costs ```
70
Outline how the decision to get a flu vaccine can be describes by the Health Beliefs Model
``` Susceptibility= “A lot of people I know have got flu symptoms” Seriousness= “It’s not something to really worry about” Benefits= “The vaccination will stop me getting sick” Costs/barriers= “The injection will be painful and it might make me ill for a while” Cues= Doctor strongly advises to have it ```
71
Outline smoking cessation using the Health Beliefs Model
Susceptibility= Is smoking affecting your health? What would it be like if you got it? Benefits/barriers= Pros and cons of smoking for you? Anything stopping you from quitting? Cues= Giving up smoking prompt
72
What is an outcome efficacy belief?
Individuals expectation that the behaviour will lead to a particular outcome
73
What is a self efficacy belief?
Belief that one can execute the behaviour required to produce the outcome
74
What factors influence self efficacy?
Mastery experience Social learning Verbal persuasion or encouragement Physiological arousal
75
Outline Ajzen's Theory of Planned Behaviour (1991)
Beliefs about outcome (expectancy) and evaluation of outcome (value) -> attitude towards the behaviour-> intention-> behaviour Beliefs about important others' attitudes towards the behaviour-> subjective norm-> intention-> behaviour Internal control factors (e.g. self efficacy) and external control factors (e.g. perceived costs/barriers)-> perceived behavioural control-> intention-> behaviour SEE DIAGRAM
76
Outline smoking cessation using the Theory of Planned Behaviour
Explore attitudes towards smoking: - What do you think about smoking? - Is smoking a good or bad thing for you? Explore the norms of important people around her: - What do your friends/family think about you smoking? - Would you like to quit for [person]? Explore whether she intends to quit smoking: - Have you ever thought about quitting? - Do you intend to quit in the next few months? Explore how much control she thinks she has: - Do you think you can quit? - What makes you think that you can’t?
77
What is the Transtheoretical (Stages of Change) model? (DiClemente, 1983)
Circle ``` (Pre-contemplation= doesn't recognize need for change or is not actively considering change) Contemplation= recognizes problem and is considering change Preparation= getting ready to change Action= initiating change Maintenance= adjusting to change and practicing new skills/behaviours to sustain change Relapse= may occur and start cycle again (OR PERMANENT EXIT) ```
78
Summarise the approaches for modifying health behaviour
Listen and validate patient’s experience Identify and remedy any gaps in knowledge Identify cues and reinforcers then modify if possible and plan rewards Identify and attempt to modify unhelpful beliefs Enhance self-efficacy Identify and problem-solve barriers to change Identify positive, relevant role models Encourage social support Tailor intervention to individual’s readiness to change Motivational interviewing
79
Define sensation
The stimulus detection system by which our sense organs respond to and translate environmental stimuli into nerve impulses that are sent to the brain
80
Define perception
The active process organising the stimulus output and giving it meaning
81
How does sensation lead to perception?
Stimulus energy (light, sound, smell etc) Sensory receptors (eyes, ears, nose, etc) Neural impulses (SENSATION->PERCEPTION) Brain (visual, auditory, olfactory areas)
82
Is perception an active process?
Yes
83
Outline top-down perception
Processing in light of existing knowledge Influenced by motives, expectations, previous experiences and cultural expectations
84
Outline bottom-up perception
Individual elements are combined to make a unified perception Influenced by activation in auditory cortex, vibration of tympanic membrane
85
What factors affect top-down perception?
Attention Past experiences (e.g. poor people overestimate size of coins compared to affluent people) Current drive state (e.g. arousal state) (e.g. when hungry notice food-related stimuli) Emotions (e.g. anxiety increases threat perception) Individual values Environment Cultural background
86
Give an example of cross-cultural differences in perception

87
What did Gestalt Laws of perceptual organisation champion?
Championed top-down processing Continuity, similarity, proximity, closure
88
What are figure-ground relations according to Gestalt Laws?
Figure-ground relations= our tendency to organise stimuli into central or foreground and a background Focus of attention becomes the figure, all else is background
89
What did Gestalt think of continuity?
When the eye is compelled to move through one object and continue to another object
90
What did Gestalt think of similarity?
Similar things are perceived as being grouped together
91
What did Gestalt think of proximity?
Objects near each other are grouped together
92
What did Gestalt think of closure?
Things are grouped together if they seem to complete some entity
93
What are the disorders of visual perception?
Visual agnosias (apperceptive and associative)
94
What is visual agnosia?
Primary visual cortex can be mostly intact (Associated with bilateral lesions to the occipital, occiptotemporal, or occipitoparietal lobes) Basic vision spared Patient not blind (Will smile at you, say hi when you come in) Knowledgeable about information from other senses (e.g. if they touch an object then naming is typically simple)
95
What is apperceptive agnosia?
Failure to integrate the perceptual elements of the stimulus Individual elements perceived normally May be able to indicate discrete awareness of parts of a printed word but cannot organised into a whole Damage to lower level occipital regions
96
What is associative agnosia?
Failure of retrieval of semantic information Shape, colour, texture can all be perceived normally Typically sensory specific e.g. if object touched, then recognised Damage to higher order occipital regions
97
What does Humphreys & Riddoch's hierarchical model (2001) of visual perception show?
``` Visual perceptual analysis -> Viewer centred representation -> Visual object recognition system -> Semantic system -> Name retrieval ```
98
In Humphreys & Riddoch's hierarchical model (2001) of visual perception, what is affected in agnosia?
``` Visual perceptual analysis *AP AG -> Viewer centred representation *AP AG -> Visual object recognition system *AS AG -> Semantic system *AS AG -> Name retrieval ``` AP AG= apperceptive agnosia AS AG= associative agnosia
99
Define: attention
Process of focusing conscious awareness Providing heightened sensitivity to a limited range of experience requiring more intensive processing 2 processes= focus on a certain aspect and filter out other info
100
What are the two processes of attention?
Focus on a certain aspect | Filter out other info
101
What are the components of attention?
``` Focused attention (the spotlight) Divided attention (paying attention to more than one thing at once) ```
102
What stimulus factors affect attention?
``` Intensity Novelty Movement Contrast Repetition ```
103
What personal factors affect attention?
``` Motives Interests Threats Mood Arousal ```
104
What cognitive processes are intertwined with attention?
Memory and perception ATTENTION (External stimuli-> sensory buffers)-> limited capacity short-term memory-> long-term memory-> responses
105
What are sensory buffers?
Register info for a few seconds which can be used to select which info info to focus on There's a limited capacity for short term memory but evidence that we can unconsciously perceive info not attended to
106
What is the cocktail party effect?
Cherry, 1953 Can focus our attention on one person's voice in spite of all the other convos When someone says your name- you hear that
107
How does attention relate to clinical skills?
Multi-tasking is easiest when skills are automatic and tasks are not too similar (e.g. writing an essay whilst listening to music) BUT the more automatic a task, the less conscious control available
108
What happens when you use a phone whilst driving?
Slows reaction times | Less attention on sensory inputs
109
When do incorrect actions occur? (attention)
Correct response is not most habitual or strongest Full attention not given to task High levels of stress or anxiety present
110
What is MSS (Medical Student Syndrome)?
Psych condition amongst medical trainees that experience symptoms of the disease or diseases that they are studying High workload, stress of exams, high anxiety related to new clinical experiences and exposure to medical knowledge Leads to selective attention to physical symptoms and misinterpretation (e.g. I have X disease)-> preoccupation
111
How does attention relate to bodily symptoms?
Focus of attention contributes to the perception of our bodily symptoms ``` Treadmill study (Pennebaker & Lightner, 1980) 1st run= headphones with no sounds 2nd= amplified sounds of own breathing or street sounds ``` Symptoms worsened with breathing but massively reduced by street sounds
112
What is pain perception?
Pain is often an important sign that the body has been damaged or something is wrong Acute pain= protects from damage or infection, expectation of perceived bodily symptoms Chronic= can be from oversensitization/dysregulation
113
How is acute pain altered by expectation of perceived bodily symptoms?
Anderson & Pennebaker, 1980 Students were told vibrating sandpaper would be: Painful (not painful) Pleasant (neutral, towards not painful) Not told anything (pain) Expectation changes the response to the same stimulus
114
How does pain perception affect chronic pain?
``` External factors Pain behaviours Suffering Emotions Thoughts Pain sensation Tissue damage ```
115
Outline the Gate Theory of Pain (Melzak, 1999)
Pain signals compete to get through ‘gate’ ‘Gate’ can be opened or closed by psychological and physical factors Explains pain relief by ‘rubbing it better’
116
What is the fear-avoidance model of chronic pain?
Strong relationships between areas - Pain - Mood, thoughts and stress - Day-to-day functioning (behaviour) Pain breeds avoidance which perpetuates stress, low mood, anxiety etc.
117
What does 'language is ubiquitous' mean?
No humans yet discovered without language Innate (Chomsky) or exposure (Putnam)?
118
What is a phoneme?
The smallest unit of speech sound in a language that can signal a difference in meaning
119
How many phonemes can humans produce? How many in English?
Humans can produce just over 100 phonemes | English language consists of 44 phonemes
120
What is a morpheme?
The smallest units of meaning in a language Typically one syllable Morphemes combined into words
121
What is syntax?
Rules and principles which govern the way in which morphemes and words can be combined to communicate meaning in a particular language
122
What is universal grammar?
Widely accepted theory that under normal conditions human beings will develop language with particular properties (e.g. distinguishing nouns from verbs)
123
What happens to children of speakers of pidgin languages?
Even though pidgin languages lack basic grammatical structures They develop languages which are fully grammatical Innate property of the brain results in this
124
Outline language development up to 12 months?
1-3 months= can distinguish speech from non-speech sounds and prefers speech sounds (phonemes) Undifferentiated crying gives way to cooing when happy 4-6 months= babbling begins (vocalizations in response to verbalizations of others) 7-11 months= narrowing of babbling sounds to include only the phonemes heard in the language spoken by others in the environment = child discriminate some words without understanding their meaning and begins to imitate word sounds heard from others 12 months= first recognizable words are spoken (e.g. dada)
125
Outline language development from 12 months to 5 years?
12-18 months= child increases knowledge of word meanings and begins to use single words to express whole phrases or requests (e.g. out, mostly nouns) 18-24 months= vocab expands betweens 50-100 words (rudimentary sentences e.g. more milk) without articles (the, a), conjuctions (and) or auxiliary verbs (can, will) 2-4 years= vocab expands rapidly at the rate of several hundred words every 6 months (linger sentences without grammar that exhibit basic language syntax) 4-5 years= child has learned the basic grammatical rules for combining nouns, adjectives, articles conjunctions and verbs into meaningful sentences
126
Outline Genie's case?
'Genie’ -was deprived of social interaction from birth until discovered aged 13 She was completely without language, and after seven years of rehabilitation still lacked linguistic competence
127
Is there a critical period in language acquisition?
Yes
128
How do genes affect language development?
Huge individual differences in language ability, some of which depend on genetic factors E.g. KE family: across three generations about 50% suffer severe language problems (e.g. difficulties understanding speech, slow ungrammatical speech) Associated with mutations of FOXP2 gene, also found in patients with similar language problems (MacDermot et al. 2005)
129
How is language affected by handedness?
Hemispheric specialization for language 95% of right-handed people have left-hemisphere dominance for language 18.8% of left-handed people have right-hemisphere dominance for language function Additionally, 19.8% of the left-handed have bilateral language functions
130
Outline Broca's aphasia
Non-fluent speech (expressive aphasia) Impaired repetition Poor ability to produce syntactically correct sentences Intact comprehension
131
Outline Wernicke's aphasia?
Problems in comprehending speech (input or reception of language) Fluent meaningless speech Paraphasias- errors in producing specific words Semantic paraphasias-substituting words similar in meaning (“barn”-“house”) Phonemic paraphasias-substituting words similar in sound (“house”-“mouse”) Neologisms- non words (“galump”) Poor repetition Impairment in writing
132
How is language made up?
``` Phonemes Morphemes Words Phrases Sentence Discourse ```
133
Where are Broca's area and Wernicke's area?
Broca's area is found in the inferior or front of the temporal lobe It's connected to Wernicke's area by a bundle of nerve fibers called arcuate fasciculus
134
What does the arcuate fasciculus connect?
Broca's and Wernicke's areas
135
What aphasia is it if comprehension is intact but non fluent agency?
Broca's aphasia
136
What aphasia is it if comprehension is impaired and non fluent agency?
Global aphasia
137
What aphasia is it if comprehension is impaired but expression is fluent?
Wernicke's aphasia
138
Do Broca's and Wernicke's areas exist?
Modern findings show that rather than there being one key connective tract relevant to language function, there are many Tremblay and Dick conclude that language function is incredibly widely distributed through the brain
139
What can lesions to the dominant hemisphere be caused by?
Stroke Traumatic brain injury Progressive neurodegenerative conditions (e.g. Alzheimer's, fronto-temporal dementias, Parkinson's)
140
What can transient aphasia be associated with?

Intact IQ but initiating, correcting and self-regulating behaviours compromised 38 year old hand surgeon, hypoxic frontal damage during cardiac arrest Intact IQ but initiating, correcting and self-regulating behaviours compromised Was polite and responsive to questions, but volunteered nothing spontaneously and asked no questions Affect remained unchanged regardless of topic
145
What are the behavioural and emotional aspects of dysexecutive syndrome?
``` Hypoactivity Lack of drive Apathetic Poor initiation of tasks Emotional bluntness ``` ``` Hyperactivity Impulsive Disinhibited Perseverative Emotional dysregulation ``` Socially inappropriate Rude, crass, prone to swearing Theory of mind difficulties Reduced empathy
146
What are the cognitive aspects of dysexecutive syndrome?
Attentional and working memory difficulties Poor planning and organisation Difficulty coping with novel situations and unstructured tasks Difficulty switching from task to task Difficulty keeping track of multiple tasks Difficulty with complex/abstract thinking
147
Give an example of the inhibition task
Name the colour of the ink the word is presented in | Unless the word is underlined, then read the word
148
What is usually damaged in impairment syndromes?
Pre-frontal lobes and/or subcortical structure damage is associated with impairment syndromes in executive functions
149
What is developmental psychology?
Scientific study of changes that occur in people over the course of their life Changes in thought, behaviour reasoning and functioning occur Influenced by biological, individual and environmental influences
150
How are children treated as patients?
Dependent on their age/where they are developmentally Affects how you communicate with, understand and relate to each other
151
How do heredity and environment influence human development?
Epigenetic The baby is an interactive project not a self powered one Nature sets out their course via gender, genetics, temperament and maturational stages Nurture shapes this predetermined course via the environment; parenting, stimulation and nutrition
152
What kind of responses are the 'least hard wired' in the animal kingdom?
Emotional responses Are the least hard wired in the animal kingdom and the most influenced by experience
153
What does a baby recognise about their mother by 40 weeks?
Recognise their mother as a memory of her has been built up in utero Via hearing, smell and taste
154
When can babies hear?
In the womb Receptive hearing at 16 weeks Functional hearing begins at 24 weeks As a result, prefer their mothers' voices to the voices of other women
155
What is functional hearing?
How baby's use what hearing they have Beings at 24th week of gestation
156
How do babies know the difference between languages?
Every language has its own characteristic rhythms and newborns can detect them
157
What smells can be recognised by babies?
Their own amniotic fluid Maternal breast odours (prefer their mother's) Others smells associated with their mother
158
What can a newborn taste?
Sweet, umami, sour, bitter (they can't taste salty until 4 months) They particularly like very sweet sugar solutions (helps before painful procedure e.g. heel pricks) and glutamate (found in breast milk) They don't like some bitter and sour substances
159
What can a baby see?
Can't see very well- newborn has blurry vision with sharpest visual acuity at the edges of the visual field ``` 12-36h= prefer mothers' face to strangers Newborns= prefer faces and face-like stimuli (particularly faces with open eyes and happy face stimuli) ```
160
What is reciprocal socialisation?
Newborns prefer to look at expressive, responsive faces Bidirectional- children socialise parents just as parents socialise children Baby: cries moves, grimaces, smiles, calms, looks Parent: mirrors, repeats, interprets, responds
161
What is scaffolding is reciprocal socialisation?
If parents responses supports or reinforces the infants efforts the infant will build on this interaction or experience and continue to develop in this area Scaffolding can occur in lots of different types of interactions not just parent child
162
How can you test reciprocal socialisation?
Still Face paradigm, Tronick 1975
163
How do parents provide a supportive environment for development?
Scaffolding Reciprocal socialisation Provision of a stimulating and enriching environment Internal working model (Bowlby, 1969) is established through this social process (baby coordinates his systems with those of the people around him)
164
How does a mother with depression affect her child?
Babies of depressed mothers adjust to low stimulation and get used to lack of positive feels In the same way - agitated mothers-> over aroused baby - well managed babies-> expect a world that is responsive to feelings
165
What is the attachment theory?
Attachment theory= describes a biological instinct that seeks proximity to an attachment figure when threat is perceived or discomfort is experienced i.e. sense of safety a child experiences provides a secure base from which they can explore their environment Process begins before birth and is supported by reciprocal socialisation
166
What is the development of attachment over the 1st year?
Birth to 3M= prefers people to inanimate objects, indiscriminate proximity seeking e.g. clinging 3-8M= smiles discriminately to main caregivers 8-12M= selectively approaches main caregivers, uses social referencing / familiar adults as “secure base” to explore new situations; shows fear of strangers and separation anxiety From 12M (corrected age)= the attachment behaviour can be measured reliably
167
What is the Strange Situation Test?
Ainsworth et al, 1978 Designed to present children with an unusual, but not overwhelmingly frightening, experience It tests how babies or young children respond to the temporary absence of their mothers-> tests ATTACHMENT Researchers are interested in two things: 1. How much the child explores the room on his own 2. How the child responds to the return of his mother Shows if child is secure or insecure
168
How can you test attachment?
Strange situation test
169
What are the main attachment styles?
Secure (65%) vs insecure (35%) ``` Secure= formed in early infancy, they are a protective factor leading to resilience throughout the life span Insecure= place individual at risk (but not causative for later problems) ``` NB. Resistant-insecure (ambivalent) and disorganized-insecure
170
What is a securely-attached child?
Free exploration and happiness upon mother's return (The securely-attached child explores the room freely when Mum is present. He may be distressed when his mother leaves, and he explores less when she is absent. But he is happy when she returns. If he cries, he approaches his mother and holds her tightly. He is comforted by being held, and, once comforted, he is soon ready to resume his independent exploration of the world. His mother is responsive to his needs. As a result, he knows he can depend on her when he is under stress)
171
What is an insecurely-attached child?
Avoidant-insecure child with little exploration and little emotional response to mother (The avoidant-insecure child doesn’t explore much, and he doesn’t show much emotion when his mother leaves. He shows no preference for his mother over a complete stranger and, when his mother returns, he tends to avoid or ignore her)
172
What is a resistant-insecure child?
Little exploration, great separation anxiety and ambivalent response to mother upon her return (Like the avoidant child, the resistant-insecure child doesn’t explore much on her own. But unlike the avoidant child, the resistant child is wary of strangers and is very distressed when her mother leaves. When the mother returns, the resistant child is ambivalent. Although she wants to re-establish close proximity to her mother, she is also resentful- even angry- at her mother for leaving her in the first place. As a result, the resistant child may reject her mother’s advances)
173
What is a disorganized-insecure child?
Little exploration and confused response to mother (The disorganized child may exhibit a mix of avoidant and resistant behaviours. But the main theme is one of confusion and anxiety. Disorganized-insecure children are at risk for a variety of behavioural and developmental problems)
174
What attachment style is most indicative of behavioural/developmental problem risk?
Disorganized-insecure
175
What does secure attachment promote?
Independence Emotional availability Better moods Better emotional coping
176
What is secure attachment associated with?
Fewer behavioural problems Higher IQ and academic performance Contributes to a child's moral development Reduces child distress
177
What is secure attachment associated with in adolescence and adulthood?
``` Social competence Loyal friendships More secure parenting of offspring Greater leadership qualities Greater resistance to stress Less mental health problems such as anxiety and depression Less psychopathology e.g. schizophrenia ```
178
How does play affect child development?
Enriches brain -> smarter brains and more BDNF Brain derived neurotrophic factor- needed for growth and maintenance of brain cells
179
What are the benefits of play?
``` Engage and interact with world Create and explore own world Experience mastery and control Practice decision-making, planning Practice adult roles Promotes language development Promotes creative problem solving Overcome fears Develop new competencies Learn how to work in group Develop own interests Extend positive emotions Maintain healthy activity level ```
180
How do types of play change from birth to 6+ years?
Solitary, spectator, parallel play, associate, co-operative, competitive 0-2 years SOLITARY= he plays alone- limited interaction with other children 2 to 2.5 years SPECTATOR= observe other children playing around him but will not play with them 2.5-3 years PARALLEL PLAY= alongside others but will not play together with them 3-4 years ASSOCIATE= starts to interact with others in their play and there may be fleeting co-operation between in play - Develops friendships and the preferences for playing with some but not all other children - Play is normally in mixed sex groups 4-6 years CO-OPERATIVE= plays together with shared aims of play with others - Play may be quite difficult and he's supportive of other children in his play - As he reaches primary school age, play is normally in single sex groups 6+ years COMPETITIVE= play often involves rules and has a clear “winner”
181
What is Piaget's theory of cognition?
Proposed Piaget's Stage Model Proposed that children's thinking changes qualitatively with age As a result of an interactive of the brain's biological maturation and personal experiences Affects schemas
182
How does Piaget's theory of cognition relate to schemas?
Development occurs as we acquire new schemas and as our existing schemas become more complex Process of assimilation and accommodation which leads to adaptation
183
What is assimilation (according to Piaget)?
Incorporating new experience into existing schema
184
What is accommodation (according to Piaget)?
The difference made by the process of assimilation
185
What is adaptation (according to Piaget)?
Whereby new experiences cause existing schema to change
186
What are the stages Piaget describes?
Sensorimotor stage (0-2y) Pre-operational stage (2-7y) Concrete operational stage (7-12y)
187
What happens in the sensorimotor stage according to Piaget?
Birth to age 2; infants understand their world primarily through sensory experiences and physical (motor) interactions with objects Object permanence Gradually increasing use of words Learning based on trial and error
188
What is object permanence?
The understanding that an object continues to exist even when it can't be seen
189
What happens in the pre-operational stage according to Piaget?
The world is represented symbolically through words and mental images- no understanding of basic mental operation Rapid language development Understanding of the past and future No understanding of the Principle of Conservation Irreversible= can't reverse actions Animism begins Egocentrism happens
190
What is animism?
Attributing lifelike qualities to physical objects and natural events
191
What is the Principle of Conservation?
Basic properties of objects stay the same even though their outward appearance may change
192
What is egocentrism?
Difficulty in viewing the world from someone else’s perspective
193
What happens in the Concrete Operational Stage according to Piaget?
Children can perform basic mental operations concerning problems that involve tangible (“concrete”) objects and situations Understand the concept of reversibility Display less egocentrism Easily solve conservation problems Trouble with hypothetical and abstract reasoning
194
What are the main limitations of Piaget?
Some researchers query whether children respond as they do to please the adult asking the question Some argue the (repeated) question is so weird (as the answer is so obvious) the child thinks the adult wants or expects you to change the original answer– when more naturalistic ways of asking the questions were developed children performed much better
195
How does child development influence the child's understanding of death?
<5y= Don't understand that death is final, universal, will take euphemisms concretely, may think they have caused deat . 5 to 10 years= gradually develop idea of death as irreversible, all functions ended, universal/unavoidable, more empathic to another’s loss; may be preoccupied with justice 10yrs to teens= understand more of long-term consequences, able to think hypothetically, draw parallels, review inconsistencies Dependent on cognitive development and experience (pets, extended family members)
196
How do cognition, emotion and relationships change in adolescence?
Adolescence involves cognitive development and physical growth, as distinct from puberty, which can extend into the early twenties Transition to formal operational stage Chronological age only provides a rough marker of adolescence
197
What is adolescence?
Transitional stage of physical and psychological human development that generally occurs from puberty (biologically defined period of rapid maturation in which a person becomes capable of sexual reproduction) to legal adulthood (a social construction)
198
What is the Formal Operational Stage?
Follows adolescence Where abstract thought emerges Adolescent begins to think more about moral, philosophical, ethical, social and political issues that require theoretical and abstract reasoning Begin to use deductive logic or reasoning from a general principle to specific information
199
What happens to the adaptive adolescent brain between age 12 and 25?
Extensive brain remodelling (myelinisation, synaptic pruning) Cognitive changes may help journey from the secure world parent(s) provided to fitting into world created by peers ``` Thrill seeking Openness to new experiences Risk taking Social rewards are very strong Prefer own age company ``` Emotionality becomes less positive through early adolescence But level off and become more stable by late adolescence Storms and stress more likely during adolescence than rest of the lifespan but not characteristic of all adolescents
200
What is the psychological impact of long-term condition?
People with 1 LTC= 2-3x more likely to develop depression (than rest of population) People with 3 LTC= 7x more likely to develop depression Increased risk of CHD and mortality from this Increased risk of death from MH problesm
201
What is the Self Regulatory Model (Leventhal, 1993)?
The model proposes that illness disrupts normality and the individual is motivated to return to a “normal”, healthy state However, for patients who have a terminal illness the ability to return to health is not possible and coping becomes more about the psychological response to the inevitability of death and dying
202
What are stages in the self regulatory model?
Representation of health threat= identity, cause, consequence, timeline, cure/control Stage 1= interpretation Stage 2= coping Stage 3= appraisal Emotional response to health threat= fear, anxiety, depression
203
What is 'interpretation' in the self regulatory model?
The patient’s attempts to make sense of their perceived symptoms
204
What is 'coping' in the self regulatory model?
Adaptive and maladaptive ways of dealing with the problem in order to regain a sense of balance
205
What is 'appraisal' in the self regulatory model?
The assessment of how successful, or otherwise that the coping stage has been
206
What is Kubler-Ross's Stage Theory?
Reactions to terminal illness Outlined 5 reactions of the person facing death 1969
207
What are Dr Kubler-Ross's 5 reactions to death?
Denial (often a psych defence to cushion the impact of grief) Anger (why me?/unfair) Bargaining (with nurses/G-d/family) Depression (intense emotional pain- helplessness/sadness) Acceptance (loss accepted, work to minimise loss and cope)
208
Why are Stage Theories common in Western culture?
We like to think linearly (like to predict/control) Need to make sense of the uncertain Applies to a number of different situations
209
What are the weaknesses of Stage Theories?
Stages are prescriptive and place patients in a passive role Do not account for variability in response (e.g. people deal with things differently) Focus on emotional responses and neglect cognitions and behaviour Fail to consider social, environmental or cultural factors Pathologise people who do not pass through stages ('good' and 'bad' patients) Some people may not reach state of resolution- may make experience harder knowing they should
210
What is bereavement?
Refers to the situation of a person who has recently experienced the loss of someone significant in their lives through that person’s death Strongly influenced by culture
211
What are typical responses to bereavement?
Loss-> first year of bereavement-> second year of bereavement 15-50% minimal grief (early) 85% minimal grief (towards second year) 50-85% common grief (early) 15% chronic grief (towards second year) SEE FIGURE
212
Who developed the responses to bereavement schema?
Bonanno and Kaltman, 2001
213
Why is it important to treat people as individuals?
Not working with 'consistent' phenomena
214
What is personality?
The distinctive and relatively enduring ways of thinking, feeling and acting that characterise a person's response to life situations
215
What are personality traits?
Relatively stable cognitive, emotional and behavioural characteristics of people Help establish their individual identities and distinguish them from others Trait= continuum along which individuals vary, like nervousness or speed of reaction Can’t observe traits but can infer from behaviour
216
What is Eysenck's Two Factor model?
Personality theory with 2 main factors: NEUROTICISM/stability= the tendency to experience negative emotions EXTRAVERSION= the degree to which a person is outgoing and seeks stimulation (2 lines cross- vertical stable to unstable, horizontal extroverted to introverted)
217

222
Who would score low/high in the NEUROTICISM category of the big 5?
``` LOW Calm Even-tempered Comfortable Unemotional ``` ``` HIGH Worried Temperamental Self-conscious Emotional ```
223
What did Eysenck suggest was the biological/genetic basis for personality traits?
Differences in customary levels of cortical arousal - Introverts are overaroused - Extroverts are underaroused Suddenness of shifts in arousal - Unstable (neurotic) people show large and sudden shifts in limbic system arousal - Stable people do not
224
What percentage of personality differences are estimated by genetic determinants?
50%
225
What is Bandura's definition of reciprocal determinism?
Cognitions, behaviours, and the environment interact to produce personality
226
What is Bandura's locus of control?
An expectancy concerning the degree of personal control we have in our lives INTERNAL= life outcomes are under personal control EXTERNAL= outcomes have less to do with one's own efforts than with the influence of external factors
227
What would Bandura's locus of control say about health?
Health may be attributed to three sources: - Internal factors (e.g. healthy lifestyle) - Powerful others (e.g. one's doctor) - Lucky (e.g. lifestyle advice will be ignored)
228
What study suggested optimists live longer?
Nun study Relatively homogeneous group Autobiographies at age 22 were analysed for emotional content and survival rate examined
229
What is intelligence?
The ability to acquire knowledge and to deal adaptively with the environment
230
What does the Binet-Simon scale measure?
Mental age Binet and Simon developed first intelligence test to ID French children that might have difficulty in school Different paces children learn at
231
How is IQ calculated?
Mental age divided by chronological age x 100 ``` >140= very superior 1% 100= 47% about average <60= 'mentally retarded'= 3% ```
232
What is an IQ of 100?
Average (i.e. test-taker's performance relative to average performance of other's the same age)
233
What is Charles Spearman's theory of intelligence?
Believed intellectual activity involves a general factor (g= general/shared level of ability) and specific facto Developed factor analysis - People who excel in one area often excel in other area - Statistical procedure which examines inter-correlations b/w different tests of mental ability Categories= verbal, mechanical, spatial, numerical (and then in middle= general)
234
What kind of intelligences did Gardner's multiple intelligences include?
``` Linguistic (Shakespeare) Logical-mathematic (Einstein) Spatial (Gaudi) Musical (Lennon and cardiologists) Bodily-Kinaesthetic (Messi) Intrapersonal (Socrates) Interpersonal (Freud) Naturalistic (Ray Mears) Existential intelligence (Sartre) ```
235
Outline the factor structure of the WAIS-IV
g - > verbal comprehension (SI, VC, IN) - > perceptual reasoning (BD, MR, VP) - > working memory (DS, AR) - > processing speed (SS, CD)
236
What kind of verbal and performance tests may happen in the Wechsler test?
``` VERBAL General info Similarities Arithmetic reasoning Vocabulary Comprehension Digit span ``` ``` PERFORMANCE Picture completion Picture arrangement Object assembly Block design Digit-symbol substitution ```
237
Why are IQ scores criticised?
Take average | Don't show specific skills
238
What did Spearman's g get divided into by Cattell and Horn (1971, 1985)?
Crystallized intelligence (gc)= ability to apply previously acquired knowledge to current problems (improves with age then stabilises) Fluid intelligence (gf)= ability to deal with novel problem-solving situations for which personal experience doesn't provide a solution (steady pattern of decline in ageing)
239
Outline the stability of intelligence (Lothian birth cohort)
Lothian birth cohort 1921 (Scotland area) N=550 They all did same test as children Data from 1932 test (first time age 11) Given same test (first time age 80) Scores consistent and stable (intelligence must be fairly stable)
240
What factors can be considered when studying cognitive ability at age 79 (Lothian birth cohort)? How much do these correlate?
Physical fitness(lung FEV1, grip strength, 6m walk time)= 0.17 Cognitive ability age 11= 0.59 Sex= 0.08 Adult social class= 0.10 APOE4 status (relates to Alzheimers)= 0.08
241
How can genetic factors and the environment affect each other?
Genetic factors can influence the effects produced by the environment - Accounts for 1/2 to 2/3 of the variation in IQ - No single “intelligence gene” Environment can influence how genes express themselves - Accounts for 1/3 to 1/2 of the variation in IQ - Both shared and unshared environmental factors are involved - Educational experiences are very important
242
In what way are IQ tests culturally biased?
Comparing people from different environments doesn’t make sense e.g. Black and white in America ``` WITHIN comparisons more valid than BETWEEN comparisons e.g. Black and white in same socioeconomic class in same area of USA ```
243
What is the difference in average IQ of males and females?
Almost none (Lothian= Boys 100.5, Girls 100.6) Possibly gender difference in performance on certain types of intellectual tasks not general intelligence MEN better at spatial, target-directed and maths reasoning WOMEN better at perceptual speed, verbal fluency, math calculations and precise manual tasks
244
What is empathy?
Being able to infer the thoughts and feelings of others and having an appropriate emotional reaction
245
What is systemising?
The drive to analyse or construct any kind of system i.e. identifying the rules that a govern a system, in order to predict how that system will behave
246
How does autism prevalence differ in males and females?
Autism 4:1 male:female ratio Asperger's 9:1 m:f Baron-Cohen explains the social and communication difficulties in autism and Asperger’s syndrome by delays or deficits in empathy whilst explaining the narrow interests with reference to skills in systemising May be under-diagnosed in females
247
What are examples of the empathy quotient? Results?
I get upset if I see people suffering on news programmes. I can pick up quickly if someone says one thing but means another I can’t always see why someone should have felt offended by a remark Results (low to high): autism, males, females
248
What are examples of the systemising quotient? Results?
I am fascinated by how machines work I find it very easy to use train timetables, even if this involves several connections I do not keep careful records of my household bills Results (low to high): females, males, autism
249
What is neurosexism?
Impossible to exclude contribution of environment and culture Findings of sex differences reflect bias gender roles
250
What is Freud's Psychoanalytic theory?
Studied hysteria Believed that symptoms were related to repressed memories and feelings Personality is an energy system (instinctual drives generate psychic energy, which constantly seeks release)
251
What is ID?
Only structure present at birth Exists totally within unconscious mind Pleasure Principle: seeks immediate gratification and release, regardless of rational considerations and environmental realities
252
What is EGO?
Operates primarily at the conscious level Reality Principle: tests reality to decide when and under what conditions the id can safely satisfy its needs
253
What is SUPEREGO?
Last to develop Contains the traditional values and ideals of family and society Morality Principles
254
What are the factors in the structure of personality?
Id Ego Superego Struggle in Psyche- ID defeats SUPEREGO in battle to control the EGO and how the EGO struggles to explain
255
What is the WHO definition of health?
Health is a state of complete physical mental and social well-being and not merely the absence of disease or infirmity
256
What is the WHO definition of impairment?
Refers to a problem with a structure or organ of the body e.g. ejection fraction
257
What is the WHO definition of disability?
Functional limitation with regard to a particular activity e.g. mobility, ADLs
258
What is the WHO definition of handicap?
Refers to a disadvantage in filling a role in life relative to a peer group e.g. access to sports centre, prejudice of employers
259
What is the correlation between disease, disability and handicap?
WHO suggests causal links between disease and disability But disability correlates with handicap, research shows a correlation of just r=0.19 between impairment and disability in 763 CHD patients Suggesting something in addition to impairment (structural problem) influences disability (functional limitations)
260
Outline Moos crisis theory of coping with illness (1977)
Have a need for social and psychological equilibrium Serious illness presents a crisis (state of disorganisation, feelings of fear, guilt, sadness etc) Crisis is self-limited because we can't remain in an extreme state of disequilibrium Affected by background, personal, physical and social environmental factors RESPONSES - Adaptive responses-> personal growth and adjustment to illness - Maladaptive responses-> poor adjustment (pysch problems, low functioning etc)
261
What factors affect adjustment?
``` Illness related-factors: Unexpected Cause and outcome Disability Prior experience Stigma Disfigurment ``` ``` Background/personal factors: Pre-existing personality Age of onset Gender SES & occupation Pre-existing illness beliefs ``` ``` Physical and social environment: Hospitalisation Accommodation and physical aids/adaptations Social support and social role Societal attitudes ```
262
How do big 5 personality traits relate to health?
Openness= no clear link to health Conscientiousness= +2 years life expectancy Extraversion= lower rates of CHD, protective respiratory disease Agreeableness= hostility associated w/ CHD Neuroticism= higher use of alcohol and smoking, higher symptom reporting
263
What did Boyce & Wood (2011) show about personality and health?
4-Year prospective study of life satisfaction 307 individuals who were newly disabled (from sample of 11,680) Average change for whole sample shows some adaptability by year 4 Agreeableness shown as strongest predictor= robust - Different adaptation for high and low agreeableness
264
Why is agreeableness the most robust predictor for adaptability to health care?
May be explained by more agreeable individuals… Having more social support and better quality of friendships More likely to follow self-care instructions More positive e.g. active, coping strategies
265
How is social network associated with risk of cardiac death?
Increased cardiac mortality inversely correlates to network size
266
How is social support related to health/smoking status (Brummett et al (2001))?
The most socially isolated cardiac patients scored higher on a hostility measure, had lower incomes, and were more likely to be smokers
267
What is the most robust social predictor of cardiac mortality?
Social isolation
268
Define: illness representations
A patients own implicit, common sense beliefs about their illness
269
What is the 'identity' of illness representations?
The label of the illness and symptoms | E.g. “I have a cold, with a sore throat and runny nose”
270
What is the 'cause' of illness representations?
What may have caused the problem, such as genetics, circumstances, trauma, etc. E.g. “My cold was caused by being run down”
271
What is the 'consequences' of illness representations?
Expected effects from the illness and views about the outcome E.g. “My cold will prevent me from playing football this week”
272
What is the 'time line' of illness representations?
How long the problem will last and whether it is seen as acute, chronic or episodic E.g. “My cold will be gone in a few days”
273
What is the 'cure/control' of illness representations?
Expectations about recovery or control of the illness | E.g. “If I rest my cold will resolve quickly”
274
What is asked on the illness perceptions questionnaire?
Identity- What symptoms are e.g. pain, tiredness Cause- “A germ or virus caused my illness” “Pollution of the environment caused my illness” “Stress was a major factor in causing my illness” Timeline- “My illness is likely to be permanent rather than temporary” “My illness will last for a long time” Consequences- “My illness has major consequences on my life” “My illness is a serious condition” Cure-Control- “There is little that can be done to improve my illness” “My treatment will be effective in curing my illness”
275
What is the 'Picture of health' study?
DRAWINGS OF DAMAGE PREDICT RECOVERY BETTER THAN MEDICAL VARIABLES 74 patients after MI were asked to draw pictures of their heart (before discharge from hospital) Recovery was assessed 3 months later, measuring work, exercise, distress about symptoms and perceptions of recovery Patients who drew damage to their heart perceived that their heart had recovered less at 3 months, that their heart condition would last longer and had lower perceived control over their heart condition - Extent of damage drawn correlated to slower return to work - Peak troponin-t not related to 3-month outcomes or return to work
276
What is Leventhal's self-regulation model (1984)?
Model of illness, cognition and behaviour How symptoms are perceived and interpreted by someone based on their illness representations, will influence their coping behaviour Symptoms evoke an emotional reaction Emotions and cognitions influence each other Coping and reappraisal can lead to adjustment of beliefs, emotions and coping strategies
277
What are maladaptive coping strategies?
“Stress caused my heart attack, smoking helps me reduce my stress levels, so I’m going to continue smoking” “Now I’ve had a heart attack, my life is as good as over, I’ll never be able to enjoy myself again” => low mood => reduce activity levels, avoid seeing friends => depression
278
What are adaptive tasks?
TASKS RELATED TO ILLNESS OR TREATMENT (Moos 1982) Coping with symptoms or disability Adjusting to hospital environment and medical procedures Developing and maintaining good relationships with healthcare professionals TASKS RELATED TO GENERAL PSYCHOSOCIAL FUNCTIONING Controlling negative feelings and retaining a positive outlook for the future Maintaining a satisfactory self image and sense of competence Preserving good relationships with family and friends Preparing for uncertain future

What did Petrie et al, 2002 show about adaptive coping intervention? Outline the sessions and results
Randomly treated 65 MI patients in hospital Intervention was aimed at modifying illness cognitions over three sessions Session 1: educated about symptoms and addressed common misconceptions of cause (e.g. stress was singularly responsible) Session 2: explored beliefs about recovery (e.g. will have to reduce activity forever) and helped patients make an explicit plan of exercise, dietary change and return to work Session 3: the action plan was reviewed, concerns about medication and symptoms were explored Patients in the treatment condition reported more positive views of their MI in terms of beliefs about consequences, time line, control/cure and symptom distress 3 months post-discharge= those treated returned to work faster etc.
280
What are the types of coping?
PROBLEM-FOCUSED Seeking relevant information about an illness Learning specific illness related procedures e.g. pacing activities, helps patients gain expertise Changing behaviour e.g. diet EMOTION FOCUSED Seeking reassurance and emotional support Learning relaxation strategies Meditation Flexibility in skills/approach used most beneficial
281
What is better- emotion or problem focused coping?
Emotion focuses coping= poorer adjustment and greater levels of depression But CIRCULAR REASONING (those who are more distressed may need to engage in more emotion-focused coping) Flexibility in approach most beneficial
282
Why is medical treatment stressful?
Threat= painful? survival? Resources= nothing I can do, can't cope
283

288
What did Suls & Wan show in 1989 "Dual process hypothesis"
Procedural and sensory information are both helpful Procedural info works by allowing patients to match ongoing events with their expectations in a non-emotional manner Sensory information works by “mapping” a nonthreatening interpretation on to these expectations
289

Greater well-being Reduced distress
292
What did Martelli's say about 'Matching preparation to coping style' (1987)?

Specific procedural and sensory info Coping skills training may also be conducted Older children >7 years benefit from info 5-7 days before Younger children benefit from info closer to procedure Modelling interventions can be hepful
295
What is TELL SHOW DO?
TELL Using simple language and a matter-of-fact style, the child is told what is going to happen before each procedure (negative, emotive words are avoided).

Participants were invited into the lab under the pretext they were taking part in a discussion about ‘personal problems’ Participants were all in separate rooms in the lab and communicated via an intercom system Participant heard actor having seizure 87% helped if they believed it was just them and the other student. But only 31% helped when they believed they were in a group of 4 people, hardly anyone helped if group was above 4
332
How did those who didn't help the epileptic actor react after finding out about the bystander apathy experiment (Darley & Latane)?
Those that didn't report the emergency appeared in distress (sweating and had trembling hands) They reported shame and guilt for not helping Reasons for not helping included not wanting to expose themselves to embarrassment or to ruin the experiment which, they had been told depended on each participant remaining anonymous from the others
333

341
What is the participative/ democratic style of leadership? Advantages/disadvantages?
Favours decision-making by the group as shown e.g. leader gives instruction after consulting the group They can win the co-operation of their group and can motivate them effectively and positively. ADVANTAGES Can win cooperation and motivate team Can improve quality of decision making DISADVANTAGES Time consuming Can lead to disagreements
342
What is the laissez-faire/ "free-rein" style of leadership? Advantages/disadvantages?
Leader does not lead, but leaves the group entirely to itself Such a leader allows maximum freedom to subordinates, i.e., they are given a free hand in deciding their own policies and methods ADVANTAGES Allows autonomous working Allows expertise to be utilised DISADVANTAGES Can lead to lack of direction Lack of ultimate responsibility holder

Both system-related and cognitive factors (46%) Cognitive error only (28%) No-fault factors only (7%)
348
What is the main medical error (in terms of fraction of claims, severe patient harm and penalty payouts)?
Diagnostic errors (not surgical mistakes or medication overdoses)
349
What are heuristics? Why are they used in clinical decision making?
Heuristics= intuitive understanding of probabilities is combined with cognitive processes to guide clinical judgment I.e. educated guesses, or mental shortcuts Usually involve pattern recognition and rely on a subconscious integration of patient data with prior experience

Shown four identical pairs of tights in a row and consumers in mall asked to pick out the pair they liked the best Consumers significantly more likely to select the far right most pair (even though they were switched around randomly each time) Consumers were able to provide justifications for their choice e.g. sheerness, strength etc. None mentioned the position
354
What is confirmatory bias?
Tendency to search for or interpret info in a way that confirms one's preconceptions (often-> errors)
355
How does confirmatory bias relate to over-confidence (Slovic, 1973)?
Experienced horserace handicappers given a list of 88 variables relating to past performance of horses and riders Asked to predict outcome of a race based on 5 most important items, then 10, 20 and 40 most important variables More confident with more variables but accuracy approx the same
356
What is the danger of over-confidence in medicine? (Podbregar)

357
What is the sunk cost fallacy? (Arkes & Blumer, 1985)
Humans don't always act rationally and often the more we have invested in the past the more we are prepared to invest in a problem in the future EXAMPLE Season ticket sold at full price, small discount or large discount Observed frequency of attendance at plays over the season Rationally, price paid for ticket should not influence how often it's used However, people who paid a higher price used the ticket more
358
What is anchoring?
Cognitive bias that describes the common human tendency to rely too heavily on the first piece of information offered (the "anchor") when making decisions During decision making, anchoring occurs when individuals use an initial piece of information to make subsequent judgments
359
How can medical decisions be made due to probability?
Many clinical situations involve making decisions on the basis of probabilities E.g. two or more competing diagnoses, alternative treatments which may be effective etc
360
What is the Gambler's fallacy?
Logical fallacy involving the mistaken belief that past event will affect future events when dealing with independent events E.g. If one patient in a clinic presents with a rare condition then it would be impossible for the next patient to present with the very same condition
361
What is the representativeness heuristic? (Tversky & Kahneman)
Used when making judgments about the probability of an event under uncertainty Subjective probability that a stimulus belongs to a particular class based on how ‘typical’ of that class it appears to be (regardless of base rate probability) While often very useful in everyday life, it can also result in neglect of relevant base rates and other errors
362
How is a thin, athletic, healthy-appearing 60 year old man having an MI an example of representativeness error?
He doesn't match the typical profile of an MI But unwise to dismiss that possibility because MI is common among men of that age and has highly variable manifestations
363
What is the framing effect?
A cognitive bias in which people react to a particular choice in different ways depending on how it is presented E.g. as a loss or as a gain. People tend to avoid risk when a positive frame is presented but seek risks when a negative frame is presented (i.e. 400 people die, 200 saved)
364
How is the framing effect affected by age?
Older adults are significantly more likely to agree to a treatment when it is positively described than they are to agree to the same treatment when it is described neutrally or negatively
365
What is the availability heuristic?
Probabilities are estimated on the basis of how easily and/or vividly they can be called to mind Individuals typically overestimate the frequency of occurrence of catastrophic, dramatic events e.g. believe that accidents cause more deaths than strokes People tend to heavily weigh their judgments toward more recent information

Processes used to acquire, store, retain and later retrieve information There are three major processes involved in memory: encoding, storage and retrieval
376
Outline the stages of memory
REGISTRATION Input from our senses into memory system (not everything registered is remembered) ENCODING Processing and combining of received info (better encoding-> increased likelihood of retrieval) STORAGE Holding of that input in the memory system RETRIEVAL Recovering stored info from memory system (remembering it)
377
What are the types of encoding?
EFFORTFUL PROCESSING= initiated intentionally, requires conscious attention AUTOMATIC PROCESSING= occurs without intention, requires minimal attention
378
Outline the depth of processing study by Craik & Tulving 1975
Students had to answer questions about a series of words which were flashed one at a time (e.g. bear) 3 types of questions asked 1) about word's visual appearance (e.g. case) 2) about sound of word (e.g. rhyme) 3) about meaning (e.g. animal?) After, given recognition test Shows types of encoding More meaning assigned to something the more likely it is to go into storage for later retrieval

Manipulation of information and direction of attention- driving Suppression of irrelevant information and undesired actions Supervision of information integration Coordination of multiple tasks to be executed in parallel Co-ordination of the sub-systems of working memory
387
What are the roles of the visuospatial sketchpad?
Storage of visual and spatial info | E.g. for constructing and manipulating visual images, for the representation of mental map
388
What are the roles of the phonological loop?
Storage of auditory/verbal info Preventing decay by silently articulating contents, refreshing the info in a rehearsal loop E.g. phone number/ reading
389
What happened in the case of KF?
Damage following motorbike accident to area between parietal and occipital lobe Working memory intact but impaired long term memory
390
Outline the overall model of memory
Info in -> sensory registers Sensory registers - -> ATTENTION-> working memory - -> direct to long term memory - -> lost Working memory (REHEARSAL loop) - -> STORAGE-> long term memory - -> info lost RETRIEVAL (ltm-> wm)
391
What is the long term memory?
Store of all things in memory that are not currently being used but are available for use in the future Allows use of past information to deal with present and the future Can hold unlimited amount of information

399
What is autobiographical memory?
Starts from age 2-3 years Language needed to help remember Aged 6 when we remember autobiographical events 'Reminiscence bump'- we remember the most in later adolescence Is it emotionally driven? Driven by defining events?
400
What is the associative network needed in memory?
Each concept represented by a node Activation of one network leads to spreading activation of related concepts and then activate neighbouring nodes (Stored ideas are connected by links of meaning, strengthened through rehearsal and elaboration) Works to a lesser extent for indirectly related nodes Multiple links make it easier to retrieve because alternative routes to locate it
401
How do we remember things?
A mental structure that represents some aspect of the world (e.g. schema for weddings even before we go to one, then reinforce it when we go) Used to organise current knowledge and provide a framework for future understanding Automatic not effortful thought e.g. stereotypes Acquired through experience
402
Outline Barlett's War of the Ghosts (1932)?
Provides a valuable insight into the reconstructive nature of human memory  STUDY 20 English participants read a traditional native american tale Retold story to each other after a short period of time Struggled in understanding its meaning and the significance of some of its aspects RESULTS Rationalisations= people tended to add material to justify parts of the story Omissions= parts of the story that were difficult to understand were left out Changes of order= storyline was rearranged in an attempt to make sense out of it Distortions of emotion= people added their own feelings and attitudes
403
How do schemas affect our memory (according to Cohen, 1993)?
Selection= info that does not fit current schemas is ignored Abstraction= we are inclined to recall the overall gist and forget the detail Interpretation= schemas provide existing knowledge to help us understand novel situations Normalisation= memories are distorted to fit with our existing expectations Retrieval= schemas help us fill gaps in our memory by making a best guess
404
What is the misinformation effect?
Distortion of a memory by misleading post-event information Show how language and wording can influence a person's recall of a incident E.g. eyewitness testimony (Loftus & Palmer, 1974) of car accident - Asked questions - Manipulate way question is asked to determine effects on recall (e.g. smashed/ collided/ bumped) Loftus & Zanni (1975)- more subtle wording e.g. the broken headlight instead of a broken headlight
405
What is the probability of recalling a word list related to?
Order in the list= serial position effect (primary and recency= most likely) Personal salience of words Delay time Distraction
406
What is rote learning?
Frequent repetition (verbal)‏ Forms a separate schema, not closely linked to existing knowledge Least efficient way to study Less deep processing
407
What is assimilation (assimilated learning)?
Fitting new information into existing schema(s)‏ Learning by comprehension Can only be used where there is link between old and new knowledge Deep processing Declarative
408
What is the PQRST method of learning?
``` P = Preview the info to learn Q = Question= write down the questions that you want to be able to answer once finished R = Read through info that best relates to questions S = Summarise the info by writing, diagram, mnemonics, voice recording T = Test= try to answer the questions ```
409
What is a mnenomic device?
Artificial structure for reorganising or encoding information to make it easier to remember Useful when info doesn’t fit existing into schemas Examples: hierarchies, chunking, visual imagery, acronyms Need to recall artificial structure to access information
410
What kind of movement helps memory and learning?
Parker & Dagnall= L-R ready better (for R handed) Acting out with hand gestures helps Links learning abstract concepts to simplify physical movement Short, intense exercise bursts are better than long
411
Why do we forget?
Ineffective encoding Decay theory Interference theory Encoding Specificity Principle
412
What is the Encoding Specificity Principle?
Retrieval will occur depending on how well the retrieval cue corresponds to the memory code
413
What is ineffective encoding?
Info not encoded in the first place
414
What is the decay theory?
Forgetting occurs because memory fades with time if not used
415
What is the interference theory?
Forgetting occurs due to competition for space from other material either from previously learned info or new information
416
How does Alzheimer's highlight the neural correlates from memory?
Hippocampus one of first brain regions to suffer damage | Memory and disorientation among first symptoms to appear
417
What is the role of the medial temporal lobes in memory? How do we know this?
Implicit memory HM & CW= significant anterograde amnesia for autobiographical info following bilateral medial temporal lobe ablation but implicit memory intact e.g. piano playing
418
What is the role of the hippocampus in memory?
Important in formation of new episodic or autobiographical memories May be part of larger medial temporal lobe memory system (involved in general declarative memory) Role in maintaining memories unknown (older memories remain stable so consolidation over time may happen outside of hippocampus)
419
What parts of the brain are important in episodic memory?
Medial temporal lobes including the hippocampus and parahippocampal cortex
420
What usually happens to memory after significant head injury?
See a period of retrograde amnesia | Depending on the site of injury anterograde amnesia
