Cognitive Psychology
the study of how information is modified, made meaningful, stored, retrieved, used and communicated to others.
Thinking
The manipulation of mental representation
Cognition
Reasoning, problem solving and decision making.
Concept
Objects, events, or ideas with common properties (concrete or abstract)
Artificial Concepts
(Formal Concept) can be defined by a set of rules or properties that each member has, and each nonmember doesn't.
Natural Concepts
No set of defining features, but instead have characteristic features.
Birds, mammals, amphibians, etc.
Prototypes
The best representative of a concept, an example that closely matches the defining characteristics of a concept.
Poems are passages that rhyme
Schemas
Generalization we develop about categories of objects, events and people.
Scripts
Schemas about familiar sequences of events or activities
Propositions
Simple ideas about how concepts are related to another.
Apples are red
Mental Models
A personal theory, a concept about how a system functions. Tend to be incomplete, naturally evolving.
Reasoning
The process through which we generate arguments, evaluate and reach conclusions about them.
Formal Reasoning
Mental procedures that yeild valid conclusions (algorithms)
Informal Reasoning
Conclusion based on the believability of a conclusion based on evidence to support
Algorithms
Using every possible way to solve a problem
Syllogisms
An argument made up of two propositions, called premises. Requires deductive reasoning.
Conversion Effect
The assumption that premises are symmetrical, when often they are not.
Heuristics
General rules that provide shortcuts, but usually produce more errors than algorithms.
Anchoring Heuristic
When you estimate an events probability of an occurance, and then make adjustments based on additional info.
Framing Effect
The way something is posed or presented to you, altering info to make something sound better.
Representativeness Heuristics
A rule for judging likelihood of something based on how well something fits our prototype or schema.
Decomposition
Dividing the problem into smaller, more manageable parts.
Working Backward
Starting at the finish or end and working towards the beginning
Analogies
Thinking of problems that are similar because similar strategies may work.
Incubation
Putting the problem aside for awhile and coming back with a fresh perspective
Striking Feature Syndrome
When an actual feature in a case chosen for a study is given too much weight
Casual Uncertainty
One cannot conclude solve and effect, because the person may be studying an atypical case.
Multiple Hypothesis
Cannot all be tested at once, have to isolate the variables independently.
Mental Sets
The tendency for old patterns of problem solving to persist.
Functional Fixedness
Using familiar objects in familiar way rather than creative ways.
Confirmation Bias
Search for information that confirms ones perspective, avoids information that refutes it.
Belief Perseverance
Once a belief is formed, it takes more compelling evidence to change it than to create it.
Risky Decisions
Decisions that we make when the result is uncertain
Overconfidence
Being unrealistically confident about the accuracy of their predictions
Group Polarization
The enhancement of groups prevailing attitudes through discussion
Language
Our spoken, written or gestured words and how we combine them to communicate meaning
Symbols
Words
Phoenemes
Basic sounds
b, ch, sh.
Morphemes
The smallest meaningful unit in a language.
(I, a)
Overregulation
Avoiding exceptions to rules overextend new grammatical rules
I have two feets
Rules of Syntax
Grammatical rules for combining sentences so that they make sense
Semantics
Meaning as derived from morphemes, words and sentences
Surface structure
The words actually spoken
Noam Chomsky
Deep Structure
The underlying meaning of a sentence
Noam Chomsky
