Psychology Flashcards
What are the forms of Non associative learning?
- Habituation - repeated stimulation leads to a reduction in response over time
- Sensitisation - an increase in response to a stimulus as a function of repeated presentations of that stimulus
- Pseudoconditioning (cross-sensitisation) - e emergence of a response to a previously neutral
stimulus simply as a result of exposures to a different but powerful stimulus.
What are the forms of Associative learning?
- classical conditioning
- Operant conditioning
- Social learning theory
How is classical conditioning produced?
By repeatedly pairing a neutral conditioned stimulus (CS e.g. bell) with an unconditioned stimulus (UCS e.g. food) that naturally evokes an unconditioned response (UCR e.g. salivation).
Eventually the neutral stimulus alone eventually evokes the desired response (salivation –
now called conditioned response, CR).
Who first demonstrated clasdical conditioning?
Pavlov first demonstrated this paradigm in dogs.
The development of the association between the CS and the UCR resulting in a CR is called?
acquisition (for animals this takes around 3 and 15 pairings)
Delayed or forward conditioning.
CS (bell) presented before UCS (food); the CS+ UCS pairing continued till UCR (saliva) appears
Backward conditioning.
UCS (food) presented before CS (bell) – not useful in
animals; used in advertising
Simultaneous conditioning.
UCS + CS presented together
Trace conditioning
CS presented and removed before UCS presented –
conditioning depends on memory trace.
*A delay of less than 0.5ms is proposed to be the optimum for trace conditioning
What is Higher-order conditioning?
the use of an already conditioned stimulus CS1 as UCS for the next level of conditioning and eliciting a CR for another stimulus CS2.
What is stimulus generalisation?
the ‘spread’ of associative learning from one stimulus to another e.g. By exposing him to loud frightening noise whenever he was shown a white rat, eventually Albert became fearful of the white rat, even when he heard no loud noise. A similar fear response was seen when any furry white object was shown to Albert.
What is discrimination?
learned responses are made only to specific stimuli and not to other similar stimuli e.g. a child may be afraid of dogs but not all four-legged animals
What is extinction?
reduction/disappearance of a learned response when the UCS – CS pairing is not available anymore
What is Spontaneous recovery?
refers to regaining a previously extinguished learned response after a period of time.
What is Counter conditioning?
a form of classical conditioning where a previously conditioned response is replaced by a new response that may be more desirable. Utilised in behavioural therapy - systematic desensitisation, aversion therapy
What is the principle of operant conditioning?
An organism learns an appropriate behaviour after many trials because the right behaviour is followed by
appropriate (desirable) consequence.
What is reinforcement?
A conditioning that leads to increase in the frequency of behaviour following learning
What is a:
- Positive Reinforcer
- Negative Reinforcer
- Primary Reinforcer
- Secondary Reinforcer
- Food for pressing a lever (given)
- Ceasing of electric shock on pressing a lever (taken away)
- Stimulus affecting biological needs (such as food)
- Stimulus reinforcing behaviour associated with primary reinforcers (money, praise)
*Both positive and negative reinforcement increase the desired response.
What is punishment?
A conditioning that leads to decrease in the frequency of behaviour following learning
What is a:
- Positive Punishment
- Negative Punishment
- Points on your driving license for speeding (given)
2. A monetary fine from a parking ticket (taken away)
Continuous (aka contingency reinforcement) reinforcement schedule
Reinforcement every time the positive response occurs - e.g. food pellet every time a rat presses a lever in an experiment
Partial reinforcement schedule
Only some of the positive responses result in positive reinforcement – the reinforcement is determined by number of responses (ratio) or time (interval)
Fixed Interval reinforcement schedule
Reward occurs after a specific period of time regardless of number of responses e.g. a monthly salary irrespective of your level of performance!
Variable Interval reinforcement schedule
Reward occurs after a variable (unpredictable) period of time, regardless of the number of responses e.g. an angler catching a fish - the first may be after 10 minutes, the next after 45, then 5 minutes etc.
Fixed Ratio reinforcement schedule
Reward occurs after a specific number of responses e.g. after completing 20 MCQs, you give yourself a coffee (or chocolate) break.
Variable Ratio reinforcement schedule
Reward occurs after a random number of responses e.g. gambling slot machines. Your first win of £20 on a gamble may occur after 3 tries; then the next win may not occur even if you play 30 times, while the third win
may follow in quick succession after the second.
Which reinforcement schedules generate a constant rate of response and why?
Variable schedules, because the chance of obtaining a reward stays the same at any time and for any instance of behaviour
What is contingency in operant conditioning?
learning the probability of an event.
What is Premack’s principle?
a.k.a. Grandma’s rule –> high-frequency behaviour can be used to reinforce low frequency behaviour
e.g. “eat your greens and you can have dessert”
An existing high-frequency behaviour (eating dessert) is used to reward low-frequency behaviour (eating greens).
What is Avoidance learning?
an operant conditioning where an organism learns to avoid certain responses or situations
*A special form of avoidance is escape conditioning seen in agoraphobia where places in which panic occurs are avoided / escaped from leading to a housebound state eventually.
What is Aversive conditioning?
an operant conditioning where punishment is used to reduce the frequency of target behaviour e.g. the use of disulfiram (noxious stimuli) to reduce the frequency of drinking alcohol
What is Covert reinforcement?
the reinforcer is an imagined pleasant event
rather than any material pleasure e.g. imagining MRCPsych graduation event to reinforce the behaviour of practicing MCQs.
What is Covert sensitisation?
The reinforcer is the imagination of unpleasant consequences to reduce the frequency of an undesired behaviour e.g. an alcoholic may be deterred from continuing to spend on alcohol by imagining his wife leaving him, being unable to support himself and ending up broke and homeless
What is Flooding?
An operant conditioning technique where exposure to feared stimulus takes place for a substantial amount of time so the accompanying anxiety response fades away while the stimulus is continuously present e.g. a man with a phobia of heights standing on top of the Burj Khalifa or the Shard. This will lead to the extinction of fear. When a similar technique is attempted with imagined not actual exposure then this is called implosion.
What is shaping?
a.k.a. successive approximation
a form of operant conditioning where a desirable
behaviour pattern is learnt by the successive reinforcement of behaviours closer to the desired one.
What is Chaining?
reinforcing a series of related behaviours, each of which provides the cue for the next to obtain a reinforcer.
What is Incubation?
An emotional response increases in strength if brief but repeated exposure of the stimulus is present. Rumination of anxiety-provoking stimuli can serve to increase the anxiety via incubation. This is
a powerful mechanism that maintains phobic anxiety and PTSD.
What is Reciprocal inhibition?
Wolpe:
If stimulus with desired response and stimulus with the undesired response are presented together repeatedly, then the incompatibility leads to a reduction in frequency of the undesired response.
e.g. A family has got a new dog. A 3-year-old child in the family is afraid of dogs and would stay in the same room with the dog only if he could sit on his mother’s lap and had his favourite ice cream.
What’s Bandura’s social learning theory?
Bandura believed that not all learning occurred due to direct reinforcement, and proposed that people could learn simply by observing the behaviour of others and the outcomes.
What are the Cognitive processing during social learning?
- Attention to observed behaviour is the basic element in learning.
- Visual image and semantic encoding of observed behaviour memory
- Memory permanence via retention and rehearsal
- Motor copying of the behaviour and imitative reproduction
- Motivation to act.
Who performed the Bobo Doll experiment and what does it show?
Bandura
Children watching a model showing aggression against a bobo doll learnt to display the aggression without any reinforcement schedules–> shows Reciprocal causation
What is Gagne’s hierarchy of learning?
1 Classical conditioning (signal learning) 2 Operant conditioning 3 Chaining 4 Verbal association 5 Discrimination learning 6 Concept learning 7 Rule learning 8 Problem solving
Gestalt law of perceptual organisation includes
Proximity = Incompletely closed figures are perceived as fully closed
Closure = Incompletely closed figures are perceived as fully closed
Continuity = Continuous items are perceived as one object
Similarity = Similar items are grouped together based on colour or shape etc.
Common fate =Things moving together are perceived as one object.
What are the non-pictorial cues for depth perception?
a. Retinal image disparity
b. Stereopsis
c. Accommodation (monocular)
d. Convergence
What are the pictorial cues for depth perception?
a. Size
b. Brightness
c. Superimposition
d. Texture
e. Linear perspective (rails converge at distance, wide apart when closer)
f. Aerial perspective (colour – blue mountains means a distant sight)
g. Motion parallax (closer it is faster it seems)
What is Visual cliff?
an apparatus used to test an infant’s perception of depth. A pane of thick glass covers a
shallow drop and a deep drop. The underlying surfaces of both deep and shallow sides are covered with the same chequered pattern. Children of six months and older will not venture to the ‘deep side’ and this is taken as an indication that the child can perceive depth
What is Autokinesis?
if light is shown from a small, dim, and fixed light source for an extended period of time in a dark room, it will appear as if the light source is moving.
What is the phi phenomenon?
a perceptual illusion described by Wertheimer. This refers to the phenomenon in which a false perception of motion is produced by a succession of still images shown with fixed time interval rapidly
What is Bottom-up theory of perception?
Gestalt is an example of a bottom-up theory. According to bottom up theories, perception is purely data driven and directly starts with the optic array. Piecing together of basic elements of the data gives rise to more complex systems.
What is Top-down theory of perception?
Gregory’s constructivist theory is an example of a top-down theory. According to this theory, retinal images are sketchy and cannot explain the complex and fully formed perceptions that we experience. Perception is best defined as a process of using information known already to formulate and test a hypothesis.
What is an illusion?
any perceptual situation in which a physical object is perceived but appears different from what it really is
What is a hallucination?
an experience in which an object (e.g. sound or light) is perceived in the absence of any corresponding object in the real world.
What are Innate visual processes?
visual scanning, tracking, fixating, figure-ground
discrimination (present from birth)
What are Learnt visual processes?
size constancy, shape constancy, depth perception, shape discrimination.
What is Dichotic listening?
feeding one message into the left ear and a different message simultaneously into the right ear
What is Cocktail party effect?
the ability of people to be able to switch their attention rapidly to a nonprocessed message. The cocktail party effect shows that certain types of stimuli can elicit switching between messages
What is Broadbent’s early selection filter theory?
Our ability to process information is capacity limited.
o A temporary buffer system receives all information and passes it to a selective filter.
o The selection is based on physical characteristics of the information – one source is selected and
others are rejected.
People can only attend to one physical channel of information at a time
What is Triesman’s attenuation theory?
physical characteristics and semantic relevance (meaning) are used to select one message for full processing while other messages are given partial processing
What is Deutsch-Norman late selection filter model?
This model rejects Broadbent and suggests that filtering occurs only later, after all inputs are analysed at a higher level.
What is Pigeon-holing?
Later Broadbent revised the early selection filter theory and stated that apart from filtering, pigeon-holing can also take place.
o Pigeonholing is similar to filtering but selection is not based on physical characters; it is based on
categorisation
What is Closed loop control?
when we first learn a task it is under conscious attention system
What is open loop control?
When we become skilled at it, open loop control takes over. Open loop is controlled by automatic motor
processes. It is fast and allows conscious attention to be diverted to other activities
What is Focused attention?
The ability to perceive individual items of information (respond discretely to the specific modality of stimuli).
What is Sustained attention?
The ability to maintain a consistent behavioral response during continuous and repetitive
activity.
What is Selective attention?
The ability to avoid distractions from internal or external cues and maintain a behavioural
or cognitive set in the face of competing stimuli.
What is Alternating attention?
The ability of mental flexibility that allows individuals to shift their focus of attention and move between tasks having different cognitive requirements.
What is Divided attention?
This is the highest level of attention and it refers to the ability to respond simultaneously to multiple tasks or multiple task demands.
What are tests for selective attention?
Stroop test and letter cancellation tasks
What is seen in psychosis/schizophrenia re: attention?
an underlying attentional abnormality for those
with a genetic predisposition for psychosis. The overall reaction time is much slower in patients with
schizophrenia and their relatives; sustained attention, distraction, verbal memory and controlled
processing are also affected.
What are the 3 different processes involved in memory?
- Encoding - It leads to the formation of initial memory traces and receives information from the
outside. - Storage - Retention of information and maintenance
- Retrieval - Accessing and recovering information from memory stores
Who divided memory to primary (short term) and secondary memory (long term)?
William James
What is sensory memory?
This is modality specific, has a large capacity but gets disrupted by the inflow of new information in the same modality.
Each sense has its own sensory memory:
- iconic (visual) lasting 0.5 seconds
- echoic (auditory) lasting 2 seconds e
No processing is involved in sensory
memory. If attention is paid to the sensory memories during perception, sensory memory gets
consolidated or ‘moves’ into the short-term memory system.
What’s the capacity of the short term memory and how long does it last?
7+/- 2 items
encoding is largely acoustic
Unaided, STM lasts 15 to 30 seconds
By maintenance rehearsal, this can be increased further up to indefinite periods.
W/o maintenance rehearsal then by 15 seconds the original material is completely forgotten
What are some tests of short term memory?
digit span+/-2
Normal reverse digit span in a working age adult is 5
What is Long term memory?
This has unlimited capacity and lasts for an indefinite duration. The coding is largely semantic, though visual and acoustic coding can occur to some extent
What is Semantic memory?
Semantic memory includes factual knowledge of the world. It is proposed to be made of multiple episodic memory components
information is stored in pure form without specification of time and place
Who proposed a working memory model and what is it?
Working memory is proposed to have central
executive and 2 arms – phonological loop and visuospatial sketchpad.
The central executive is capacity limited but modality free, similar to attention system.
The phonological loop consists of auditory rehearsal loops while visuospatial scratch pad consists of pattern recognition and movement perception components.
The 4th component of WM is sometimes called episodic buffer. This is a multimodal store that integrates info from the slave systems onto LTM. This buffer is important for chunking.
What is primacy and recency regarding memory?
In organic anterograde amnesia which is better preserved?
Regardless of the length of a list, the initial words (primacy) and last few words (recency) are remembered better than those at the middle of the list.
recency is better preserved than primacy
What are modes of retrieval (i.e. moving from LTM -> STM)?
-Recognition (solving MCQs)
-Recall (actively searching and reproducing),
-Reintegration/reconstruction (recollection of past
experiences based on certain cues).
An eyewitness testimony is a reconstructive memory, which is a mode of retrieval from long-term memory. However, reconstructive memory of events as in eyewitness testimony is affected by the type of questioning asked to elicit the memory.
Who plotted the forgetting curve and what does it show?
Hermann Ebbinghaus
-Forgetting is maximum in the first few hours (NINE), and the rate of forgetting gets less with time.
-Forgetting is never complete, and some information is
retained over longer periods of time, even for life.
-Recalling the material during the test period increases the probability of remembering items
or events.
-Continuous motor skills, such as cycling and swimming, show no forgetting at all. But
discrete motors skills such as typing are lost more quickly.
What are flashbulb memories?
Distinctly vivid long-lasting memories of a personal circumstance surrounding a person’s discovery of
shocking events.
*forgetting curve for the flashbulb memories is far less
affected by time than other types of memories.
What is the Decay theory of forgetting?
neural engrams breakdown with time. This means that disuse with time is the cause of forgetting
What is the Displacement theory of forgetting?
Displacement theory states that due to capacity limitation new info replaces old information.
What is the Retrieval failure theory of forgetting?
Retrieval failure theory states that due to lack of proper cues to recall we forget things.
What is interference theory of forgetting?
According to interference theory forgetting occurs due to interference.
When newly learnt material interferes with recall of old material, this is called retroactive interference.
Proactive interference refers to the interference of new learning from older learnt material.
What’s amnesia?
Difference between anterograde and retrograde?
a marked impairment in episodic memory
Anterograde Amnesia: The loss of the ability to form or
retain new episodic memories after an injury/lesion/event
Retrograde amnesia: The loss of episodic memories that were stored before brain damage had
occurred
What’s Transient global amnesia?
transient cerebral ischemia causing a temporary lack of blood supply to the regions of the brain concerned with memory functions.
The main features include sudden onset of severe anterograde amnesia with a retrograde amnesia for the preceding days or weeks
*if this amnesia occurs without brain injury it is psychogenic amnesia
What is Fugue?
a type of psychogenic global amnesia in which there is a sudden loss of all autobiographical memories, knowledge of self and personal identity. Usually, there is a period of wandering, and there is an amnesic gap upon recovery. It usually last a matter of hours or days. Memory recovery is complete after few hours or days.
what is Rey-Osterrieth complex figure test?
non-verbal memory test. Here the subject is first asked to copy a complex geometric figure and then to draw from memory after an interval of 30 minutes. The recall is impaired in patients with dementia and amnesic syndrome
what are Wechsler memory tests?
subject is asked to read a short story from the Wechsler memory scale containing 25 elements and both immediate and delayed recall after an interval of 30 minutes is tested.

3.5 years
The brain areas mediating performances in STM are principally?
the pre-frontal lobes
The phonological STM system is mediated by?
the left hemisphere regions of Broca’s area and
prefrontal cortex
The visuospatial STM system is mediated by?
the parietal and prefrontal areas of the right
hemisphere.
The brain areas responsible for LTM include?
the regions of the limbic system especially the
hippocampus and the entorhinal cortex of the medial temporal lobe

Situationlism and Humanistic school theories of personality?
Unique features (idiographic) •Variable and situational (situationalism)
Allport’s theory of personality
- Cardinal traits: influential, core traits
- Central traits: 5 – 10 traits, less general
- Secondary traits: least important, least consistent traits that only close friends can notice.
Cattell’s approach to personality?
Surface traits are correlated to one another but not important for understanding one’s personality and Source traits that are basic building blocks of the 16 PF questionnaire devised by Cattell.
Eysenck’s approach to personality?
3 dimensional traits. These are neuroticism
vs. stability), psychoticism and extraversion (vs. introversion
Cloninger’s psychobiological model of personality?
four dimensions of temperament:
- Novelty-seeking (includes frustration avoidance, impulsive decision-making)
- Harm-avoidance (pessimistic worry about the future, passive avoidant behaviour, fear of
uncertainty) ; - Reward-dependence (sentimentality, social attachment, and dependence on praise and approval)
- Persistence (high perseverance and tolerance of frustration)
Which may manifest as 3 components of character:
self-directedness, cooperativeness, and self-transcendence.
What are the DSM clusters of personality?
In general Cluster A personalities are associated with
low reward-dependence. Cluster B personality with high novelty-seeking and Cluster C personalities with
high harm-avoidance traits.
mad, bad, sad
What is Rotter’s locus of control theory?
a single trait theory
What are the Big Five Traits acc. to McCrae & Costa?
- Openness
- Conscientiousness
- Extraversion
- Agreeableness
- Neuroticism
(OCEAN)
Age related Big Five Trait changes
NEO decreases with age; AC
increases with age.
Principles of projective tests for measuring personality
iindividually administered tests to obtain information about emotional functioning.
based on the principle that ambiguous unstructured open-ended situations stimulate projection
of an individual’s internal emotional world onto the stimulus (environment)
Examples of of projective tests for measuring personality
-Rorschach is the most commonly used, consists of 10 inkblots, sequentially presented and asked
to describe. Has two phases – free association and inquiry phase –
-Thematic Apperception Test (Murray) TAT has 20-30 pictures and one blank card and the subject
has to make a story from each depicted picture; not all cards are used. Stimuli somewhat more
structured.
-Jung introduced Word Association Test (WAT). In WAT and
-sentence completion test
-Draw-a-person test
Examples of non projective tests for measuring personality
Minnesota multiphasic personality inventory (MMPI)
Q-sort technique
The International Personality Disorder Examination (IPDE):
Who theorised the pyramid of needs and what are the components?
Maslow
physiological –> safety –> belonging –> self-esteem –> self-actualisation
Features of self-actualising people
Spontaneous in their ideas and actions.
Creative.
Interested in solving problems.
Appreciate life.
Have a system of internalized independent morality.
Able to view all things in an objective manner.
What is Yerkes-Dodson Law?
An inverted U-shaped curve relates the level of arousal with the performance of an act. Optimum arousal (moderate) is required for best performance; too low or too high arousal proves to be a hindrance e.g. sexual performance.
Sources of high need for Achievement include:
- Parents who encouraged independence in childhood
- Praise and rewards for success
- Association of achievement with positive feelings
- Association of achievement with one’s own competence and effort, not luck
- A desire to be effective or challenged
- Intrapersonal strength
- Desirability
- Feasibility
- Goal Setting abilities
Ekman’s primary human emotions
6 –> surprise, fear, sadness, anger, happiness and disgust
3 components of emotion
- Subjective ‘cortical’ experience 2. Physiological ‘visceral’ changes 3. Associated behavioural (‘skeletal’) changes.
James-Lange theory of emotions
Perception of a stimulus leads to bodily (skeletal and visceral) changes. The peripheral responses send feedback to the cortex via thalamus leading to the perception of the emotion.
‘Emotion is secondary to physiological changes
Cannon-Bard theory of emotions
On the perception of a stimulus, thalamus coordinates signals to cortex leading to a conscious experience and simultaneously sends signals to hypothalamus leading to physiological changes.
Schachter-Singer labelling theory of emotions
On the perception of a stimulus, both physiological changes and a conscious experience of general arousal take place simultaneously
This theory suggests that emotions result from both physiological changes and the context. For example if your heart is racing and you’re about to have an exam you label yourself as afraid, but if your heart is racing and your about to kiss your boyfriend/girlfriend you label your emotional state as excited.
Stimulus for emotion arises via a combination of physical sensations and the mind appraisal of them.
Lazarus cognitive appraisal theory of emotions
appraisal precedes affective reaction – hence affective primacy cannot be supported
Serotonin Transporter and life events
individuals with one or two copies of the short allele of the 5-HT T promoter polymorphism exhibited more
depressive symptoms, diagnosable depression, and suicidality in relation to stressful life events than individuals homozygous for the long allele
What are the three systems of Sigmund Freud’s Topographical model of the mind?
Unconscious, conscious and preconscious (Maintains the ‘repressive barrier’ to censor unacceptable wishes and desires )

- cycles lasting < 24 hours
- cycles lasting more than a day
- Infradian rhythms that occur as a result of seasonal changes
What is an internal pacemaker located in the anterior hypothalamus that regulates many biorhythms?
suprachiasmatic nucleus
What are external time cues that drive biorhythms?
zeitgebers
The strategies to improve encoding include:
Using imageries
Mnemonics
sing primacy-Recency effects
Chunking
The theory of motivated forgetting suggests that we forget things because unconsciously we want to. This is based on the psychoanalytic concept of
Repression
The modification of memories in terms of one’s general attitude is called

What is a common cause of absent mindedness?
Failure of prospective memory
Who introduced Type A / Type B personality classification and what are they?
Friedman and Rosenman
Type A persons show impatience, excessive time consciousness, insecurity, high competitiveness, hostility and aggression and are incapable of relaxation. They may be high achievers and workaholics. Type B persons are relaxed and easy-going; creative, often self-analyze and evade stress but cope poorly when under stress.
If the conditioned stimulus (CS) ends prior to the application of unconditioned stimulus (UCS) it is called
Trace conditioning

The cognitive deficit that is characteristic of delirium is
Poor attention span
In studies on arousal levels related to different emotions, which emotion produces the maximum rise in temperature compared to all other emotions?
Anger
What is Sternberg’s Triarchic Theory of (Successful) Intelligence?
intelligent behaviour arises from a balance between analytical, creative and practical abilities, and that these abilities function collectively to allow individuals to achieve success within particular sociocultural contexts
Cognitive processing during social learning
. Attention to observed behaviour is the basic element in learning. 2. Visual image and semantic encoding of observed behaviour memory 3. Memory permanence via retention and rehearsal 4. Motor copying of the behaviour and imitative reproduction 5. Motivation to act.
Raven’s progressive matrices test is used to assess
General intellectual ability (nonverbal intelligence)
Which one among the following refers to the act of bringing past experiences as they happened into conscious awareness?
The process of recalling an entire memory from a partial cue, like remembering a speech upon hearing the first few words, is called reintegration.
Information is held in the long term memory by the process of
Elaborative rehearsal
Amnesic syndrome is characterised by a marked impairment in

Blocking (retrieval failure)
What are Maslow’s M deficiency needs (D motives) and growth/being needs (B motives)
deficiency needs - Safety needs, Physiological needs, Love and belonging needs, Esteem needs
The commonest cause of long-term forgetting is
Retrieval failure
Of all sensory systems, the system least developed at birth is?
Vision
Visual acuity reaches near adult levels by 6 months of age
What is the perceptual set?
perceptual bias that predisposes the perceiver to notice only certain aspects of a stimulus and to ignore the other aspect
- determined by factors both in the perceiver and in the stimulus
- influenced by Emotions
- influenced by past experiences
What are the 2 parts of attitudes?
-Beliefs are based on our knowledge of the world and link an object to an attribute. They
are non-evaluative and objective e.g. ‘USA is a nation built on capitalism’.
-Values relate to the importance or desirability of the object. It is largely subjective and has
preferential patterns attached e.g. ‘I do not like capitalism’. Values can turn beliefs to
attitudes – ‘I dislike American people’.
What is the Three-component model of attitudes?
- Affective component: what the person feels about the object (favourable/ unfavourable
evaluations) – e.g. I love chocolate - Cognitive component: thoughts, beliefs, knowledge about the object – e.g. Chocolate keeps me active
- Behavioural component: actual or intended responses to the object e.g. I eat chocolate
every day
What are the Functions of attitudes?
-Knowledge function: attitudes are frames of reference that simplify the world, help make quick appraisals
-Value expressive function: reflect fundamental self-concepts – self-expressive and maintains personal integrity e.g. vegetarianism
-Social adjustment function: help to function in a group setting, social acceptance
-Ego-defensive function protects from character or personal deficiencies – this function
makes attitudes very resistant to change
What is Cognitive dissonance theory?
Who coined it?
People strive for consistency between thoughts, feelings and actions. If there is a discrepancy
between different attitudes (cognitive dissonance) or between attitudes and behaviours (attitude-behaviour discrepancy), then this initiates and drives either a change in attitudes (more common) or a change in behaviours
Coined by Festinger
What is the 1-Dollar 20-Dollar experiment?
All subjects in an experiment were asked to do a very boring repetitive task for 30 minutes. The first group was a control group; the second group (called 1-
dollar group) was paid $1 to say that the task was fun and interesting, the third group (called 20-dollar group) was paid $20 to say that the task was fun and interesting. All participants were asked to rate how enjoyable they had found the task. Contrary to popular belief, the group, which was paid more, did not appreciate the boring task.
As they obtained a good incentive, they
did not develop a dissonance. They lied about its usefulness but in fact they did not change their
belief about the boring nature of this task. In contrast, the lowly paid group did experience a cognitive dissonance between the two facts - ‘This task is boring’ and ‘I am doing this task without much incentive’, hence they changed their initial attitude towards the task and, in fact, started liking the task
How to reduce dissonance apart from modifying attitudes or behaviours?
- Removal or denial of the dissonant cognition
- Trivialising the dissonant cognition
- Adding a new consonant cognition to counterbalance the dissonance
What is the Thurstone scale?
measures attitudes
hundreds of statements are produced pertaining to a particular topic. These statements are presented to a
sample (similar to a panel of judges) who is asked to score the statements on an 11 point scale. A set number of statements e.g. 10 each on both extremes (positive and negativeattitude) are chosen based on the consistency of scores given by the judges.
What is a Likert scale?
measures attitudes
includes graded ‘agree’ to ‘disagree’ measures. This is one of the most popular and statistically more reliable measures. It is easy to construct, and no assumptions are made about the equality of intervals
Five responses to each statement
What is Sociometry?
used to measure interpersonal attitudes in a repertory grid-like fashion i.e. who like whom tables. These are called sociograms.
What is Osgood’s semantic differential scale?
Which bias might it be subjec to?
used to measure verbally expressed attitudes. s. It
allows different attitudes about a particular topic to be measured on the same scale
7 points on the scale
It may be subject to positional response bias.
What is the Theory of looking glass self?
by Cooley suggests that like a mirror,
others around us reflect our self-image
*We develop self-concept by Reaction of others
What is touching the dot experiment?
aka rouge test
It demonstrates Self-recognition
When a red dot is unknowingly placed on the face of a child, the child starts touching its face to
explore the dot when a mirror is shown. This ‘touching the dot’ phenomenon does not occur less
than 15 months of age. 5 to 25% infants touch the dot by 18 months while nearly 75% touch the
