Stereotypes can be positive or negative, and they are widely shared, simplified, evaluative beliefs about the personality traits and behaviors of a social group and its members
In forming impressions of others, we process information holistically using 'implicit theories of personality' (Asch), and we integrate this information linearly to reach a final impression, with a heavier weighting on earlier information due to the attention effect (Anderson)
The 'Motivated tactician' model incorporates both top-down (Asch) and bottom-up (Anderson) thinking in forming impressions, depending on motivation and cognitive resources
Biases in impression formation include weighting initial information more heavily, giving more attention to unusual traits or behaviors, and weighting negative information more heavily
Stereotypes are acquired early in social development, play a role in building group identities, and become more pronounced with social tension and conflict
Stereotype activation is an automatic process, where schemas are accessible and can influence reactions even if not endorsed by the individual (Devine, 1989)
Challenging stereotypes can occur before or after activation, influenced by processing goals, general attitudes, awareness, cognitive resources, and motivation
Stereotype threat is when an individual feels performance pressure due to negative stereotypes against their group, leading to poorer performance, especially in situations where negative stereotypes are present (Steele and Aronson, 2004)
The essential cognitive function of stereotyping is to systematise and simplify information from the social environment in order to make sense of the world
Impression formation is important at an interpersonal level (e.g., friends, strangers) and wider social level (e.g., job interviewing; jury service; political voting)
In forming impressions of others, we process information about them holistically, using 'implicit theories of personality' in interpretation and inference
Some traits have a central role in integrating this information and organising the impression
We integrate this information into a holistic picture as it is presented ('on-line')
We process information about others elementally (not holistically), following the algebraic rules of combination (not implicit theories of personality)
We integrate this information linearly to reach a final impression using all of the information given (not 'on-line') - with a heavier weighting on earlier information due to the attention effect
We use both top- down, deductive thinking (Asch) and bottom-up, inductive thinking (Anderson) in forming impressions, depending upon motivation and cognitive resources
