social cognition Flashcards
Heuristics
Mental shortcuts and other strategies to reduce cognitive load in decision making
Representative Heuristic
Judgement of probability that object A belongs to class B by similarity and resemblance
Errors in Representative Heuristic
Overlooking
a. Base rate probability
b. Sample size
c. Effect of chance
Adjustment and Anchoring
Estimating the value by anchoring on an actual value and then making adjustments
Availability Heuristic
Judgement of the probability of an event depends on ease of retrieval of information (instances of events)
Availability Heuristic is affected by
a. Retrievability (familiarity or salience of info)
b. Effectiveness of search
c. Imaginability (easier to imagine, the more available it is)
In-group inflation
To what extent you think your group has contributed to history
Parochial knowledge Bias
Historical events involving in-group can be assessed with more fluency
Three predictions of week 8 availability heuristic paper
- Parochial knowledge should exist in memory
- Degree of parochial knowledge correlates with in-group inflation
- In-group inflation should attenuate if we equate the relative accessibility with in- and out-group events (make out-group events more accessible, while leaving in-group alone)
Fluency Test
List out important historical events (in-state and out-state for experiment 1 but only out-state in experiment 2)
- generally, in-state participants can list more events than out-state
When are heuristics used?
- familiar domains
- approach emotions
- unimportant tasks
- when accuracy is not important
Prospect Theory: Gain Frame
Risk averse — don’t take the risk, prefer a sure outcome
Prospect Theory: Loss Frame
Risk seeking — already at a loss, not much left to lose, would have more to gain instead so rather choose the one with at least some chance of gain
Subjective Value Function
The amount of psychological impact that a certain amount of gain vs loss has on an individual
Subjective Value Function: Gain vs Loss
Steeper for losses, loss has a more significant SVF compared to gain
In general, people are loss averse, they rather not lose
Role of the Unconscious
Better when we are distracted but we know that we are going to be asked about it again later.
Because, unconscious is not limited by cognitive capacity, allows us to organise information
Also see an increase in clustering — organisation of information
Heider, Social Inferences
Humans have a natural tendency to explain behaviours using human-like traits
Common Sense Psychology
People ascribe causes to others’ actions
a. Person — Traits, character, disposition, motivation
b. Situation
Personal Causality
Intentional
Impersonal Causality
No intention, on accident or due to the situation
Kelly, Social Inferences
Discounting and Augmentation principle
Discounting Principle
Aware of multiple plausible causes of behaviour but the presence of a facilitation cause leads all other plausible causes to be discounted
Facilitative Cause
Cause that is present that is sufficient in promoting the behaviour
Augmentation Principle
Presence of an inhibitory cause would augment the perceived role of the facilitative cause
Inhibitory Cause
Something that would prevent the behaviour from occurring
Consistency
Actor behaves the same way, towards the same stimulus, all the time
Distinctiveness
Actor behaves the same way, toward other stimuli
Consensus
Other people behave the same way, toward the same stimulus
Internal Attribution (Consistency, Distinctiveness, Consensus)
Consistency: High
Distinctiveness: Low
Consensus: Low
External Attribution (Consistency, Distinctiveness, Consensus)
Consistency: High
Distinctiveness: High
Consensus: High
