Chapter 8 Flashcards
Cognition
How information is processed and manipulated when remembering, thinking, and knowing
What is thinking?
How we represent ideas and use ideas to solve problems and make decisions
Thinking
Mental manipulation of representations of information in our environments
Congnitive psychologists study though and understanding resulting from thinking
Symbolic Representations
Abstract mental representations (MRs) that consist of words and ideas
Analogical Representations
MRs that have some of the physical characteristics of real world objects
Symbolic
Mental representation that does NOT correspond to the physical characteristics of which it represents
Concept
A generalized idea or thought
- represents a group of objects, people, events, situations, with common characteristics or attributes, a category of things
Natural Concept
Acquired through everyday perceptions and experiences - animals, trees, clouds, cars
Formal Concept
Artificial Concept
- clearly defined by a set of rules
- a formal definition, algebra, grammer, vocabulary
Prototype Model
understood/stored as a prototype (ideal example) of that concept
Decision Making
Choosing one instead of others
- a mechanism for making choices at each step of the problem-solving process
- part of problem solving and occurs at each step of the problem-solving process
Problem Solving
Set of activities to systematically
- analyze a situation
- then generate, implemet, and evaluate solutions
Problem Solving Model
Step 1: Identify and define the problem (be specific)
Step 2: Brainstorm possible solutions
Step 3: Explore possible solutions (+ and -)
Step 4: Select one solution to try (decision)
Step 5: Implement the solution (act)
Step 6: Evaluate the solution
Trial and Error
With limited possibilities
Algorithms
Step-by-step procedure that guarantees accurate solution when applied appropriately properly
- using a math problem to solve a test problem
Heuristics
Mental shortcuts help us make decisions based on how easy it is to bring something to mind
- no guarantee of accuracy or usefullness
- availability, recognition, representative heuristics
Fixation
Using a prior strategy when a new one might be better
Functional Fixedness
Fixated on usual functions (neglecting unusual usages)
Reasoning
Mental activity of transforming information to reach conclusions
Inductive Reasoning
Driven by data; botton-up, specific to general
Deductive Reasoning
Driven by logic; top-down; general to specific
Decision Making
Evaluating alternatives and making them choices among them, attempting to maximize outcome
Decisions
Derived from experience/used to estimate the likelihood of something happening
Availability = Heuristic
Representative Heuristic
How closely a new object or situation is resembles or matches an existing prototype
