Lecture 3 - Social Cognition and Perception Flashcards
Outline what is social cognition
Attitudes Perceptions Judgements Expectations Influence beliefs intentions behaviour Rational, reasoned decision maker
Define Information processing perspective
Assumes act like computer, logical
Cog processes understanding how people construct own social world
Cognitive structures and processes affect and affected social context
Outline a cognitive miser
Put as little effort into thinking possible to be more efficient
Short cuts
Help towards:
Cognitive encoding and stereotypes
Outline Categorisation
Short cut strategies simplify incoming info
Simplifying perceptions
Grouping - treated similar way
Promotes cognitive economy
Outline the rule based approach of categorisation
Every category represented by set necessary and sufficient features
Who created the rule based approach
Bruner et al 1956
Outline issues of Categorisation
Hard define rules - doesn’t always work (bachelor)
Can disagree - camel as Vehicle?
Doesn’t indicate how well something represents category
What was the Prototypical approach based on
Reaction rule based approach
Who created the Prototypical Approach
Rosch 1975
Barsalou 1991
Outline the Prototypical approach
Similarity. Family matching. Common attributes family members
Members share something in common - not completely identical
Often average but sometimes most extreme
Considered fuzzy sets centring around prototype
Boundaries not clear
Outline Exemplar Approach
Specific instances
Does not have to be a good example or representative
Outline associative networks
Network linked attributes activated through spreading activation
Different in different contexts
Link key attributes which activated depends context
Define a schema
Top-down Organised, specific Cognitive representation Specify features and relationships Generalise time and space dependent individuals personal experience
Define the 3 types of a Schema
Person schema
Role schema
Scripts schema
Define a Person Schema
Individualised or generalised stereotypes
Define a Role schema
How someone in particular role should behave
E.g. a lecturer
Outline a Script Schema
Schemas about events
What happens when a schema is activated
Schemas influence information processing inference
Conceptually driven processing
Implicitly activated, affect judgement and behaviour
Guide how we encode (attend, interpret) remember and respond (judge and interact)
How do we know which schema is activated
Which schema activated driven by salience, relevance and personal importance
Outline Bargh, Chen and Burrows 1996 study on automaticity and subliminal priming of old age stereotypes
Ppts unscramble sentences
Experimental condition: contained words specifically relevant old people
2nd experimenter blind conditions and timed how long ppts afterwards walked down corridor
Outline RESULTS Bargh, Chen and Burrows 1996 study on automaticity and subliminal priming of old age stereotypes
Those primed old age stereotypes walked more slowly down corridor compared neutral primed ppts
People behave according primed schema
Outline a cognitive miser
Social perception as problem solving task
Cognitive laziness
Rely heuristics decision making and interpersonal perception
Process salient info - standard out
Result mistakes and biases
Who investigated heuristics
Tversky and Kahneman 1974
Name the 3 heuristics outlines by Tversky and Kahneman 1974
Availability
Representativeness
Anchoring and Adjustment
