Chap 4-5 Flashcards
Overconfidence bias
Tendency to have greater confidence in our judgments & decisions than actual accuracy warrants (experts too)
Dunning-Kruger effect (double-curse of incompetence)
Ppl unskilled in domain lack metacognitive ability to realize they r incompetent
Selective attention
Act of focusing awareness onto particular aspects of experience, to exclusion of everything else
Snap judgements
Rate face on trustworthiness, competence, aggressiveness, likability, & attractiveness
Judgements same whether between 100 & 1000ms , or unlimited time
Dimensions to evaluate faces
1) trustworthiness (approach or avoid)
2) dominance (physical strength)
Baby faces
Infantile features -> nurturing response
In adults : assumed to be warmer, more honest, naïve, weaker
Thin slices of behaviour
Quick judgements similar to judgments made after long time (good prediction of future sometimes)
Eg: personality from look of bedroom
Caveats of snap judgments
1) Mixed findings
2) Some traits more accessible than others
3) First impression studies -> aggregates, not individuals
4) Self-fulfilling prophecies (our own behaviour towards someone may in turn influence the way they act towards us, as we expect them to act)
Behavioural Confirmation
Own behaviour unknowingly causes the effect we expected to observe
Misleading firsthand info
1) self fulfilling prophecies (behavioural confirmation)
Act in ways that don’t reflect true attitudes & beliefs (misleading)
2) impression management
3) attempts to build rapport
4) pluralistic ignorance
Pluralistic Ignorance
Ppl act in way that conflicts with private beliefs, cuz falsely think that their own beliefs conflict with beliefs of group (but maybe everyone think the same)
Judgments
1) Limited, Incomplete
2) Misleading (first-hand info & second-hand info)
3) Affected by way info is Framed
Framing effects (definition)
Way info is presented (strongly influence judgements)
Misleading secondhand info
Ppl transmit info in way that furthers personal or ideological agenda (eg: news coverage)
News coverage (misleading secondhand info)
1) Emphasis on negative & sensational (if it bleeds it leads)
2) Selective reporting
3) Leading questions (confirmation bias: want to confirm what they want to be true)
Primacy effect (order effect)
Initial info presented in body of evidence colours interpretation of subsequent info
-> disproportionate influence on judgement
Recency effect (order effect)
Last info presented = better remembered, thus disproportionate influence on judgement
-> more likely when large gap between 2 pieces of info
Gestalt school
“The whole is greater than the sum of its parts”
When trying to make sense of world around us, mind perceive objects as elements of more complex systems, not simply focus on on every small component (eg: white triangle seen in white space between black jagged edges)
Framing effects (types)
1) Order effects (primacy & recency effects)
2) Gestalt school (whole>sum of parts)
3) Spin Framing (positive & negative framing)
4) Temporal Framing (Construal-Level Theory)
Construal-Level Theory
1) Higher-Level construal:
Abstract terms (psychologically distant actions & events)
2) Lower-Level construal:
Concrete terms (psychologically close at hand actions & events)
Belief perseverance
Ppl interpret evidence as to maintain their initial beliefs
1) Scrutinize disconfirming evidence & accepting confirming evidence
2) Confirming evidence: relevant & reliable
Disconfirming evidence: irrelevant & unreliable
3) Remembering strengths of confirming evidence & weaknesses of disconfirming evidence
Bottom-up processing
Stimulus -> Perception
Data-driven approach
Top-Down processing
Pre-existing knowledge -> Perception
Theory-driven approach
Meaning of stimuli actively construed (not passively recorded)
Person Schemas
Contain info about specific individuals (appearance, personality, likes, dislikes, behaviours)
Event Schemas & Scripts
Let us how what we can expect in given situation & how we should behave
