emotion and decision making Flashcards
injuries to the vmPFC
integrates emotion and cognition - injury will reduce ability to feel emotion and the quality of their decisions
when we consult how we feel about a decision, it is not as effective = emotions and decisions are interlinked - feelings can bias and influence.
emotional carryover effect
Johnson & Tversky 1983
ppts read newspaper stories to induce positive/negative mood then estimated fatality frequencies for various potential causes of death.
those who read negative stories = more pessimistic estimates.
it was the mood iteself that generally affected all judgements - risk perception can be impacted by mood.
availability heuristic
overestimate the likelihood of things happen = poor risk assessment
Solvic et al (1978) asked lay people to estimate the number of deaths per year due to different hazards = tendency to overestimate infrequent causes of death while underestimating more frequent causes. information read recently more likely to come to mind
weather, mood and happiness Schwarz & Clore 1983
interviewed 84ppts on sunny/rainy days about happiness and satisfaction - judgments were influenced by current mood which was influence by the ambient weather.
negative impacts of bad moods was eliminated when ppts were induced to attribute their present feelings to transient external resources (e.g. made aware of the influence of the weather on mood and that mood is temporary).
Jonauskaite et al 2019
colours and emotions - the association of yellow with joy
55 countries
to what extent does correlation between yellow and joy vary across the world.
ppts shown the word ‘yellow’
correlation moderated by annual rainfall and proximity to the equator - yellow is most joyful for those who often see grey skies/rain
e.g. hardly existent in Egypt but v. strong in finland and moderate in UK/US
Good Day Sunshine (Hirshleifer & Shumway, 2003) - relationship between morning sun and stock exchange
sun was strongly correlated with stock returns in key cities, after controlling for sun, rain and snow are unrelated.
capturing the mood of the public (Bollen, Mao & Pepe, 2011)
analysed all tweens in the second half of 2008 - banking crisis, obama first black president = lots of change, good and bad.
looked at mood states and what was happening = immediate and specific effect on emotions of tweets
risk and affect
2 types of risk
- risk as feeling = fast, instinctive and intuitive reactions to danger, hardwired within us
- risk as analysis = logic, reason and deliberation, careful assessment
need both to prevent chaos
affect heuristics
gut feeling. may develop influenced by knowledge.
affect influences decisions - subconscious process while judging the risks and benefits of something depending on positive and negative feelings associated with a stimulus
the gut feeling
Zajonc 1980
affective reactions are often the first - automatic and guide information processing and judgement = make decisions quickly and efficiently
happens alongside rationality
affect heuristics
when emotions matter
- in a positive state = likely to perceive high benefits, low risks and prepared to try new things
- negative state = see the activity as being low in benefits and high in risk = conservative choices
Hsee 1998 - looked at how we see things can be used to influence choices - ice-cream
overfilled 7oz ice-cream was valued as more than undefiled container with 8oz
- this was reversed when options were judged together –> % of the cup that was filled influence how valuable it was seen to be
presenting volume in different ways impacts judgement
risk and benefit judgement
people base judgements of an activity or technology on how they feel and what they think
if feelings are favourable = judge risks as low and benefits as high.
this can be manipulated to prove information just about risks/benefits
Finucane et al., (2000)
affect heuristic in judgement of risks and benefits
ppts given stories about whether nuclear power plans were good –> either presenting high benefit or low benefit
view was influenced bu what they read (high/low risk or benefit) - would also infer about whether other part of the equation was high/low without being told anything about it. e.g. high benefit has no mention of risk but this would be inferred to be low.
manipulating information presented changed judgements and perception
dual process theory to assess risk affectively and rationally
Dener-Raj and Epstein 1994
ppts offered $1 if they picked a red jellybean from an urn without looking.
wither 7 in 100 or 1in 10 chance - ppts reported that although they knew probability was against them they thought they had a better chance with more red beans
why some people are reluctant to trust experts - dual process their
differ in the extent to which deliberative/affective thinking influences risk perception - people are reluctant to trust experts as feel confused and uncomfortable
communicating risk as absolute and relative
medical findings are often reported in a way that causes panic - we respond differently to direct numbers than frequency
Evans and Horton 2009 - statistical illiteracy dangers
patients need to have dialogue for treatment/risks/benefits but many cannot make informed choices unless they understand the information, much of which involves stats/graphs
- decision making will only work if both the doctor and patient are clear about what the numbers actually mean
Solvic et al 2000
study using % and numbers in decision making
experienced forensic psychologist and psychiatrists asked to judge the likelihood of a patient committing an act of violence within 6 months of being discharged
wording has a big impact - presented as total numbers = more conservative decision making whereas % made them a more abstract concept
Suppression of emotion
bad idea and often counterproductive - may reduce expressive behaviour but have very little effect on subjective experience.
suppression is cognitively costly, would be more useful to devote this to reappraisal –> impairs memory for details of what triggered the emotion
white bear experiment
think of anything apart from the white bear = more likely to think of the white bear
reappraisal
reframe the meaning of stimuli that led to an emotional response. dissipates the emotional response = mitigates the physiological and neural responses to events as well as self-reported negative feelings
effect of time to reduce the effect of emotion
let time pass before making a decision as acute emotion is short lived and the strength will fade
reducing the effect of emotion on decision making
suppression, reappraisal, time
