All of Psychology Flashcards
What is an attitude?
a positive or negative evaluative reaction toward a stimulus, such as a person, action, object, or concept e.g. can include behaviour such as healthy eating
When do attiuted have stronger influence on our behaviour?
when situational factors that contradict our attitudes are weak
–> if atitute is inglign with the situation
Recall the theory of planned behaviour, specifically the role of atiiture towards a topic
The believes and evaluation of an outcome directly influence (are) the attitute towards a behaviour
Attitute directly influenced the planning of behaviour
What is cognitive dissonance?
It is a conflict between 2 opposing opinions and believes
e.g. I’m a smoker vs Smoking is bad
What is the role of the social norms and environement in health beahaviour accoriding to the theory of planned behaviour?
Might directly influence the intention to do a behaviour
What are the ways to resolve cognitive dissonance?
At the example of smoking
-
Change behaviour:
- quitting, which might be difficult and thus avoided
-
•Acquire new information:
- Such as seeking exceptions e.g. “My grandfather smoked all his life and lived to be 96”
-
Reduce the importance of the cognitions (i.e. beliefs, attitudes).
- A person could convince themself that it is better to “live for the moment”
What makes a message more effective?
- Reaches recipient
- Is attention-grabbing
- Easily understood
- Relevant and important
• Easily remembered
What makes a messenger more persuasive?
Credible e.g. doctors
- Trustworthy e.g. objective
- Appealing e.g. well presented
What is framing?
Referes to the emphasis of benefits or loss concerning a speicial statement etc.
When are loss-framed messages regarding health behaviour more effective?
to take up behaviours aimed at detecting health problems or illness (e.g. HIV testing)
When are gain-fraimed messages regardning health behaviour changes more effective?
to take up behaviours aimed at promoting prevention behaviours (e.g. condom use)
What is a stereotype?
Generalisations made about a group of people or members of that group, such as race, ethnicity, or gender. Or more specific such as different medical specialisations (e.g. surgeons)
What is a prejudice?
To judge, often negatively, without having relevant facts, usually about a group or its individual members
What is discrimination?
Behaviours that follow from negative evaluations or attitudes towards members of particular groups
Explain how stereotypes and prejudices can influence medical care?
It is shown that these factors do influence medical care:
- e.g. GPs are less likely to take on new case when there is a history of mental illness
- Hip replacements are more likely to be suggested to men
What is social loafing?
the tendency for people to expend less individual effort when working in a group than when working alone
When is social loafing more likely to occur?
- belive thtat individual performance is not being monitored
- he task (goal) or the group has less value or meaning to the person
- The person generally displays low motivation to strive for success
- The person expects that other group members will display high effort
Explain the role of gender and culture in social loafing
Occurs more strongly in all-male groups
• Occurs more often in individualistic cultures
What are the factors that could reduce the tendency for social loafing?
- Individual performance is monitored
- Members highly value their group or the task goal
- Groups are smaller
- Members are of similar competence
What is conformity?
Which factors influence conformity?
Conformity= the areeing within a group
Influenced by
- group size
- the larger the group the higher the confomity
- no further change when group larger than 5
- Presence of a disagreer
- if one disagrees –> more likely for more to disagree
- culture
- greater in collectivistic cultures
Explain the 5- step bystander decision process
- Notice the event
- Is the event an emergency?
- Social comparison: look to see how others are responding
- Assuming responsibility to intervene
- Diffusion of Responsibility: believing that someone else will help
- Self-efficacy in dealing with the situation
- Decision to help (based on cost-benefit analysis e.g. danger)
Which interventions could be undertaken to increase helping behaviour?
- Reducing restraints on helping
- Reduce ambiguity and increase responsibility
- Enhance concern for self image
- Socialise altruism
- Teaching moral inclusion
- Modelling helping behaviour
- Attributing helpful behaviour to altruistic motives
- Education about barriers to helping
Which factors influence obedience?
- Remoteness of the victim (how far away/facing them)
- Closeness and legitimacy of the authority figure
- Diffusion of responsibility: obedience increases when someone else administers the shocks
- Not personal characteristics
What is the concept of group think?
the tendency of group members to suspendcritical thinking because they they are striving to seek
agreement
What are the advantages and disadvantages of the three leadership roles?
Explain the conecpt of group polerization
the tendency of people to make decisions that are more extreme when they are in a group as opposed to a decision made alone or independently
Which factors make group think more likely?
When a group…
- Is under high stress to reach a decision
- Is insulated from outside input
- Has a directive leader
- Has high cohesiveness
Which social phenomen did Ash investigate when putting a suspect into a group of actors and asking for recognisisng the length of different lines?
Conformity
Roughly discribe the Milgram Experiment
Experiment used to investgate obedience
- Shock generator used to apply punishment
• Shocks grew increasingly intense with each mistake
Describe the Darley & Latane Experiment
Expreiment to analyse, explain the bystander effect
- Helping student having an epileptic seizure in an adjacent room.
- 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.
- If participant had not acted within first 3 minutes they never acted.
What is an error?
the failure of a planned action to be completed as intended (i.e., error of execution) or the use of a wrong plan to achieve an aim (i.e., error of planning).
Name examples of medical errors
- incorrect diagnosis
- failure to employ indicated tests
- error in the performance of an operation, procedure, or test,
- error in the dose or method of using a drug.
Explain the role of medication errors in the NHS
It has big effects
- estimated to account for 12000 deaths per year
- and £ 0.75-1.5 billion additional costs per year
What are the causes for diagnostic errors?
Are the largest errors occuring in the health care system
Explain the characteristics of the “hot” system in clinical decision making
Explain the characteristics of the cold system in clinical decision making
What are the “two systems” in clinical decision making?
There is a “hot” and a “cold” system in clinical decision making
What are heuristics?
What is their role in clinical decision making?
Heuristics are often refered to a rule of thumb due to prior experiences
- Heuristics usually involve pattern recognition and rely on a subconscious integration of patient data with prior experience
What is confirmatory bias in medical decision making?
What is a way to prevent this?
The tendency to search for or seek, interpret, and recall information in a way that confirms one’s preexisting beliefs or hypotheses, often leading to errors
–> Can be prevented by making differential diagnosis
What is the role of overconfidence in medicine?
Often clinicians are overconfident concerning a diagnosis
- doctors reporterd “completely certain” of why a patient died were wrong 40% of the time
Explain the role of sunk cost fallcy in clinical decision making
- already invested time and money makes it less likely to step back from a diagnosis/ procedure etc.
Explain anchoring and the role of anchoring effect in clinical decision making
a cognitive bias that describes the common human tendency to rely too heavily on the first piece of information offered (the “anchor”) when making decisions.
–> might lead to ignoring further informations in making a diagnosis
What is representative heuristic?
It is used when we judge the probability that an object or event A belongs to class B by looking at the degree to which A resembles B. When we do this, we neglect information about the general probability of B occurring (its base rate)
- E.g: Bob loves classical music, plays chess when growing up and playes golf. What is more likely?
- A= he is a classical trumpet player
- B= he is a farmer
- Many would choose A because of steriotype but B is just a lot more likely in the population
Might lead to neglect of basic information
What are Representativeness errors?
Example:
- A 60-yr-old woman who has no known medical problems and who now looks and feels well reports experiencing symptoms earlier of feeling short of breath, sweaty and clammy, feeling sick, and feeling faint.
- This does not match the typical profile of an MI, which is typically characterised by chest pain.
- Error–> sent her home
- BUT, it would be unwise to dismiss that possibility because MI is common among women of that age and has highly variable presentations
Explain the role and importance of algorythms in clinical decision making
They can be used to limit heuristics and individual errors in clinical decision making
- often based on probability
- An algorithm is a procedure which, if followed exactly, will provide the most likely answer based on the evidence.
- where everything is well defined –> very usefull, but that is not the real life situation
Explain the role of framing and age
Overall: older patients are more suspectible to framing and are more likely to agree on a treatment option when framed positively
Explaitn the availabilty heuristic
People are more likely to
- overestimate the probability of a catastrophic (but unlikely) event
- overestimate the probability of a more recent event to occur again
–> easier, vivid recall of information
Explain how cognitive errors and heuristics in clinical decision making can be imprved?
- Education and Training
- teach in med school
- Recognise that heuristics and biases may be affecting our judgement even though we may not be conscious of them
- Feedback
- Increase number of autopsies Conduct regular and systematic audits Follow-up patients
- Accountability
- Establish clear accountability and follow-up for decisions made
- Generating alternatives
- Establish forced consideration of alternative possibilities e.g., the generation and working through of a differential diagnosis. Encourage routinely asking the question: What else might this be?
- Consultation
- Seek second opinions
- Use of algorithms
- Use of clinical decision making support systems
Define learning
a process by which experience produces a relatively enduring change in an organism’s behavior or capabilities
What are the two processes named under non-associative learning?
- Habituation
- Sensitisation
What is Habituation?
A form of non-associative learning
- Habituation is a decrease in the strength of a response to a repeated stimulus (e.g. getting used to a busy road at night when moving)
What is sensitisation?
A form of non-assoicative learning
Sensitisation is an increase in the strength of response to a repeated stimulus
e.g. listening more careful to nose once it has a meaning to you
What is an unconditiones stimulus in classical conditioning?
A stimulus that elicits a reflexive or innate response (the UCR) without prior learning
–> e.g. food causing salivation
What is a conditioned stimulus in classical conditioning?
A stimulus that, through association with a UCS, comes to elicit a conditioned response similar to the original UCR
e.g. bell in pavlovs dog
What is an Unconditioned Response in classical conditioning? (UCR)
A reflexive or innate response that is elicited by a stimulus (the UCS) without prior learning
e.g. salivation caused by food
What is the conditioned response in classical conditoning?
A response elicited by a conditioned stimulus.
e.g. Salivation in response to bell
What are the factors that increase the strength of classical conditioning?
- There are repeated CS-UCS pairings
- The UCS is more intense
- The sequence involves forward pairing (i.e. CS -> UCS)
- The time interval between the CS and UCS is short
Explain the time-course of extinction in classical conditioning
Quite easily forgotten when unpaiting of CS and CR/UCR
What is stimulus generalization?
A tendency to respond to stimuli that are similar, but not identical , to a conditioned stimulus.
–> e.g. all snakes are dangerous
What is stimulus discrimination in classical conditioning?
The ability to respond differently to various stimuli.
– E.g. A child will respond differently to various bells (alarms, school, timer)
– A fear of dogs might only include certain breeds
How can classical conditioning can be exploted in a health situation?
E.g. chemotherapy and nausea
- Hospital can be percieved as CS to induce Nausea
- Can be undone by using overshadowing –>
- unpleasant drink is given with chemo the first times
- drink will become CS, not the hospital
- drink won’t be administered later
- patient feeling less sick
Explain the Two-factor theory of maintenance of classically conditioned associations e.g. fear
- Trauma (UCS) and Needle (CS) leading to FEar
- Avoid injections –> fear reduced –> avoidance is increased
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 occur
What is positive reinforcement in operant conditioning?
1) occurs when a response is strengthened by the subsequent presentation of a reinforcer (does not say anything if it is good or bad)
* if you do it you will get something
What is negative reinforcement in operant conditioning?
occurs when a response is strengthened by the removal (or avoidance) of an aversive stimulus
- if you do that, you don’t have to do this
What are primary and secondary reinforcers in operant conditioning?
Primary reinforcers= needed for survival e.g. food, water, sleep, sex
Secondary reinforcers: stimuli that acquire reinforcing properties through their association with primary reinforcers e.g. money, praise
What is positive punishment in operant conditioning?
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)
What is negative punishment in operant conditioning?
occurs when a response is weakened by the removal of a stimulus (e.g. phone confiscated)
When comparing punishment and reinforcement: what is more successful?
Reinforcement is much more sucessful in getting desired behaviour than punishment
- punishment makes undisired less likely
- reinforcement can teach new behaviours
How do continous and partial reinforcement differn in
- the speed of learned behaviour
- the retaining of learned behaviour
- Continous reinforcement
- new behaviour is quickly learned
- but also faster forgotten
- Partial reinforcement
- new behaviour takes longer to learn
- but also takes longer to forget
Explain fixed and variable time and fixed and variable ratio scedule in operant conditioning
- Fixed interval schedule: reinforcement occurs after fixed time interval
- Variable interval schedule: the time interval varies at random around an average
- Fixed Ratio Schedule: reinforcement is given after a fixed number of responses
- Variable Ratio Schedule: reinforcement is given after a variable number of responses, all centered around an average
How does operant conditioning play a part in health behaviour?
MAny influences but e.g. in chronic pain
- when patients shows pain and links it to medication request
- the sympathy from others (i.e. positive reinforcement) leads to a higher use of painkillers and e.g. more rest etc.
What are the key hypothesis of Banduras social learning theory?
- Observational (vicarious) learning - We observe the behaviours of others and the consequences of those behaviours.
- Vicarious reinforcement - If their behaviours are reinforced we tend to imitate the behaviours
What are the things required for a sucessful modeling in Bandurals social learning theory?
- Pay attention to model
- Remember what was done
- Must be able to reproduce modeled behavior
- If successful or behavior is rewarded, behavior more likely to recur
When do we copy behaviour of someone (according to Banduras social learning theory?
We don’t imitate the behaviour of everyonewe encounter
• 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)
What is health behaviour?
Any activity undertaken by an individualbelieving himself to be healthy, for the purpose of preventing disease or detecting it at an asymptomatic stage
What are the scales where health behaviour promotion/interventions can take place?
- Individual level
- COmmunity level
- Population level
Does health education work?
Often: not really
- though information is imporatant (and more effective when tailored to people (e..g use condoms insead of abstinence)
- More than just education needed for health behaviour changes
Accoriding to learning theory: how does reinforcement lead to unhealthy eating?
- Positive reinforcement:
- Dopamine (feel good), filling an empty void/boredom.
- Praise for preparing a high-fat meal for the family.
- Negative Reinforcement:
- Avoid painful emotions by comfort eating.
How does punishment lead to unhealthy eating?
- Punishment:
- Preparing a low fat meal is criticised.
- Limited/delayed positive reinforcement for healthy eating:
- Efforts at dietary change/weight loss go unnoticed by others; Avoiding future health problems is too remote.
What are behavioural modification technics that help with healthy 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 (eg stress) and ‘healthier’ responses:
- Eg Can you think of something other than eating that makes you feel better? Maybe something relaxing or exercise?
Explain the use of positive reinforcement in health behaviour
Though not 100% sucessful, there stll can be succes seen (biggest in comparison to punishment etc.)
- Involve significant others to praise healthy eating choices
- Plan specific rewards for successful weight loss
- Vouchers for adherence to healthy eating & weight loss
- Improved self-esteem (positive reinforcement).
- Reduction in symptoms of breathlessness (negative reinforcement).
What are the limitations of reinforcement programms?
- 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)
- • Impracticalandexpensive.
Does fear arousal work?
No–> when we are scared of something, we tend to look away and also avoid the information
- low to moderate formultations now are more effective
Explain the role of social learning in health behaviour
Has a big role (expecially in teenagers)
- e.g. large peer group influence in smoking (+family influence)
- promoting workshop including resisting peer pressure for smoking in role-plays is sucessful
What is the expectancy-value principle for health behaviour?
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
Which factors influcence the likelyhood to make a health decision (Rosenstock)
(Health believe Model)
The backround of a person influences everything but also
- How suspectible am I to get that outcome? (percieved suspectibility)
- How serious is the outcome? (percieved seriousness)
- Together: feed into percieved threat
- What are the risks and benefits if I do this? (risks and benefits)
- Cues to action (e.g. someone advises me to do something)
What is outcome efficacy?
Individuals expectation that the behaviour will lead to a particular outcome
What is self-efficacy?
Belief that one can execute the behaviour required to produce the outcome
Explain the Theory of Planned behaviour
The intetntion to persecute a planned behaviour is influenced by
- Attitute towards the behaviour
- dependant on the beliefs and the evaluation of the outcome
- Percieved behavioural control
- dependant on internal control factors
- and external control facors
- Subjective norm
- strongly influenced by by beliefs about important others perception of behaviour
Explain the Transtheoretical Model (Stages of Change Model)
- Pre-contemplation
- does not recognise the need for change
- not actively considering change
- Conetmplation
- recognised problem and considers change
- Preparation
- is getting ready to change
- Action
- is initiating change
- Maintainance
- Can go either into
- relapse or
- or permanent change
- adjusting to change and getting used to new forms to sustain
- Can go either into
Explain the COM-B model
Three factors influence behavioural change
- Capability
- influenced by
- physical (skills)
- psychological (skilly, knowledge)
- influenced by
- Opportunity
- social (social influences)
- physical (enviromental resources and context)
- Motivation
- Reflective (beliefs about outcome, intentions, goals)
- Automatic ( reinforcement, emotions
What is the Bahaviour Change Wheel?
COM-B Wheel = 9 intervention functions and 7 categories of policy (on basis of the COM model)
Which factors influcence self-efficacy?
- Mastery experience
- Social learning
- Verbal persuasion or encouragement
- Physiological arousal
What is compliance?
What is treatment compliance?
the action or fact of applying with a wish or command
–> extent to which patients follow doctors’ prescription about medicine taking
–> old fashioned term because it is too one sieded –> patiene follows doctors order
What is adherence?
What is the difference to compliance?
refers to the extent to which patients follow through decisions about medicine taking
What are the differnt forms of adherence?
It is a wide spectrum from
- Overadherence via
- perfect adherence to
- uneradherenace
How many pople usually adhere to their recommended treatment?
In long-term conditions: about 50% adhere to treatment
What is the differnece between and the relation of intentional and unintentional non-adherence?
Unintentional
- a patient does not have the capability or resources to adhere to the treatment
Intentional :
- patiens beliefs and motivations lead to non-adherence (e.g. avoid side-effects etc)
Relation:
- they overlap e.g. if someone does not consider medication important (belief) it might be more prone to forgetting it
Explain the COM-B model
It is a model to describe behaviour
- Capabilita, Opportunity and Motivation all (bidirectionally) influence behaviour
- Capability and Opportunity also directly influence Motivation
What are the consequences of non-adherence to treatment?
•Poor health outcomes
•Increased healthcare costs
- Viswanathan et al. (2012) – It is estimated that in the USA, a lack of medication adherence:
- Causes nearly 125 000 deaths per year
- Causes 10% of all hospital admissions
- Costs the healthcare system $100-289 billion per year
Explain the role of capabiliy in the COM-B model in regards to adherence
- Psychological –> Capacity to engage in the thought process
- unterstnadment of disesase and treatment
- cognitive funciton (unterstanding, juding)
- Executinve funciton (planning)
- Physical
- ability to adapt to lifestyle changes (e..g walk to supermarket etc.)
Explain the role of Opportunity in regards to treatment adherence (COM-B model)
- Physicla opportunity
- financial resources
- access (availibilty of medicaiont)
- characteristic of medicine (taste, smell, ROA)
- Social support
- Social
- religious beliefs
- stigma of disease/fear of disclosure
Explain the role of Motivation in treatement adherence in regards to the COM-B model
- Reflective (Evaluation and plans)
- perception of illness
- beliefs about treatment
- outcome-expectancy
- self-efficacy
- Automatic (emotions)
- mood state/disorders
- stimuli or cues for action
Which factors highly influence treatment adherence in regards to perception of the treatment?
- Doubt about Necessity of treatment with
- Concerns about side-effects
–> low adherence
What are interventions that can be made to increase treatment adherence?
- Improve understanding of illness and treatment
- Help patients to plan and organise their treatment –> e.g. via daily text message, incoorperating wife to put tablet onto table etc.
–> Can already be via simple methods
What can be done in a consultation to facilitate informed adherence
Check the patient’s understanding of treatment, and if necessary:
- Provide a clear rationale for the necessity of treatment
- Elicit and address concerns
- Agree a practical plan for how, where and when to take treatment
- Identify any possible barriers
What are behaviou change techniques?
•A systematic strategy used in an attempt to change behaviour
What is the difference between behaviour change tequnique and an intervention?
Intervention= broader and can include more than one technique
Name examples of behaviour change techniques
- Providing information on consequences
- Prompting specific goal setting
- Prompting barrier identification
- Modelling the behaviour
- Planning social support
How can a patient-specific behaviour change technique be chosen?
Apply it to the example of healthy eating
- Behavioural target specification
- increasing the amount of Mediterranian diet
- Behavioural diagnosis
- Who? –> e.g. people
- What? –> decrease non-mediterranian diet type
- When? –> all the time
- How Often? –> all the time
- Where?– >Home, supermarket, cafe etc.
- Who With? –> people influencing diet of target
- Intervention strategy selection
- using COM-B model to explore barriers
- Implementation strategy selection
- Selection of specific BCTs
List effective mechanism that can influence bahavioural change
- Self-monitoring
- Motivational interviewing
Explain the concept of self-monitoring and how it can help to change behavioural techniques
- An individual keeping a record of target behaviours
- Additional information recorded can help to identify barriers e.g. mood, weather
- Role in increasing physical activity and healthy eating studied –> very effective
But: can be Time-consuming over the long term
Explain the concept or motivational interviewing
It is a style of consultation in which
The doctor
- MI ‘Spirit’ –> non-judging+ open minded
- MI-consistent behaviours
- MI-inconsistent behaviours
- Using specific techniques
Looking for signs of: in patients
- Change Talk/Intention
- Stage of Change e.g. readiness to change
- Co-operation, engagement or disclosure (client engagement/involvement)
- Resistance to change (client resistance)
- Self-confidence
- Sense of discrepancy
Explain the structure of implementation intentions in the change of health behaviour
Action plans
- Normally: If-then
- Think about critical situation and act accordingly:
- IF it’s Friday morning at 9am THEN I will go for a run from my house around the park
Plannin in advance increases the cue to action
Explain the role of incentives in implementing a change in behaviour
Reinforcement
- e.g. giving money to people to stop smoking etc.
- can be cost effective
- raie awareness
- bring individuals in contact with health service but
- Normally no lon-term effects and and might be expensive long-term
Is it effective/possible to target mutliple behavoiours at once?
Yes: Targeting multiple behaviours at the same time may lead to greater overall change but individual actions less effective
Focus on 2-3 points
Does tailoring educational materials to individual result in larger changes
Yes – small benefit on effectiveness of behavioural interventions
What is Implememtation of Intention?
action plans, think about critical situations to act and appropriate responses within those situations
Name an example how an implementation of intention could look like?
- If-then aspect “if I do this, then this will happen”
- Planning in advance makes outcomes more possible
- Strengthens connection between a good situation to act and a suitable action à behaviour is more likely to be enacted
Define Sensation
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
- ‘Is there anything out there?’
Define Perception
Perception: The active process of organising the stimulus output and giving it meaning
- ‘What is it, where is it, what is it doing?’
–> Making sense of the sensory information
What is Bottom up perception?
• Individual elements are combined to make a unified perception of pure sensory information we are recieving
What is Top down perception?
How is is connected to bottom up perception?
Top down: Processing in light of existing knowledge, expectiations etc. –> e.g. backmasking
Bottom up and top down work together to influence the perception of a stimmulus
