2-2 (10/7) Cognition and Language Flashcards
Basic building blocks of abstract thoughts. Mental groupings of similar persons, places, ideas, and objects.
Concepts
Concepts are stored as complex hierarchies in the __________ part of the ________.
Long Term Mem, Semantic Memory
Purpose of ____: To simplify all the information in our memory
Concepts
When one concept is activated, another closely related concept pops into mind.
Priming Concepts
Concept Experiment
Meyer and Schvanneveldt. Pairs of letter strings. Participants are asked if they are both words. Participants were quickest to determine that both were words when they are semantically linked.
How do we form concepts in our mind? Two ways
By definition and by prototype
Typical member of a category that has the most defining features of that category
Prototype
Example of Prototype
Robin vs Penguin. The more prototypical, the more likely we are to recognize them as a category.
1st step to Problem Solving. Mental images, seeing the problem in our minds.
Represent the problem
Representing the problem: Intuitive theories of the way things work. When accurate, they allow us to quickly diagnose and solve problems. Allows for efficiency
Mental Models
Example of Mental Models
Righty tighty, lefty loosey
2nd step in Problem Solving. Aimless.
General Solution
General Solution. Hit or miss approach. The simplest, but not the most efficient
Trial and Error
General Solution. Step by step procedures guaranteed eventually to produce a solution. Must consider and try many different solutions.
Algorithms
General Solution. Mental shortcuts, rules of thumb that may/may not lead to the solution. Speedier, but error prone.
Heuristics
Heuristics example
C O O L K C – CK is a common ending, the word is Clock
General Solution. Solution seems to pop into mind all of the sudden. Seems to arise when we hit a barrier. Relax, reframe the problem
Insight
Blind Spot in PS. People often times conceptualize problems in ways that make the problems seem impossible. Belief that there is no solution.
Representation Failures
