Theories Flashcards
Theory Based Categorization
Includes categorization by:
Classical Approach - isolating features of a category
Prototype Approach- finding characteristic features of a category
Exemplar Approach - finding example category members
Theory-Based Approach - Using experience to construct a theory about the category
Sapir-Whorf Hypothesis
Behavior is determined by language
- > Strong version has been rejected
- > Supporting evidence: Color sorting task in Russian vs English
- > Contrasting evidence: Thought isn’t limited by language

Chunking Theory
Experts form more chunks that contain more information than the chunks created by novices
Template Theory
Chunks that are used frequently are developed into complex templates
Mental Model Theory (Johnson-Laird)
- People construct mental models while performing reasoning tasks
- A model is a representation of the possible states of nature
- assumes that people engage in deductive reasoning more than they do.
Collection of Dual System Theories
General Theory, that there is a system 1 (unconscious, parallel, fast) and a system 2 (conscious, rule-based, limited capacity, linked to intelligence)
1) Heuristic-Analytic Theory
2)
Heuristic Analytic Theory
- Heuristic Processes (System1)
- Analytic Processes (System2)
- > Singularity Principle: Only one mental model is considered
- > Relevance Principle: The most plausible model is considered
- > Satisficing Principle: First adequate model is accepted
- Limitation: oversimplifying
Social Contract Theory
people can detect cheaters
Theory of formal discipline
learning an abstract rule system can affect reasoning about everyday events
- rejected due to lack of evidence
Terror Management Theory
people deploy cognitive defences when prompted to consider their own death which impairs performance on cognitive tasks.
Base rate Neglect
Cognitive error, in which we ignore the initial probability of something.
Conjunction Fallacy
Assumption that the combination of two things is more likely than one of the two things by itself.
Support Theory
A given event will appear more or less likely, depending on how it is described (-> framing)
Expected Utility Theory (Neumann & Morgenstern)
- people make decisions in order to maximize their utility
- Expected Utility = P(x) * U(x) | U(x) = Utility of the event
Prospect Theory (Tversky & Kahnemann)
- theory in behavioral economics that says:
1. Individuals identify a reference point representing their current state
2. Individuals are more sensitive to potential losses than to gains - Limitations: doesn’t explain why; Social and emotional factors are neglected
Sunk Cost Effect
The tendency to continue something, once effort/time/money has been already invested in it, even if the behavior is maladaptive.
Framing Effect
Influence of objectively irrelevant aspects of the situation on decision making
- example: wording
Omission Bias
Tendency to prefer inaction when engaged in risky decision making
-> Avoidance of anticipated regret
Rational-Emotional Model (Anderson)
Decision making is determined by rational factors based on information and emotion
- major emotions are regret and fear
Relational Models Theory
- 4 basic mental models representing social interactions
1. Communal Sharing
2. Authority Ranking
3. Equality Matching
4. Market Pricing
Social intuitionist Model (Haidt)
Consists of a set of links connecting the types of psychological processing intuition, judgement and reasoning
- Cue -> Intuition -> Judgement -> (post-hoc)Reasoning
- Persuasion affects someone else’s judgement only via his/her intuition
