Problem Solving Flashcards
Goal
Destination solution
Characteristics of problem solving
Goal directedness
Sequence of steps
Cognitive operations
Subgoal decomposition
How do we solve problems? Gestalt
Focus on the whole
Gestalt grouping - relationship among items
Insight
Difficulties in problem solving (6)
Persistence of set Incorrect problem representations Functional fixedness Negative set Individual differences Lack of expertise
Operators
Legal operations moves or functions
Representational change theory
Emphasis on factors that allow people to overcome a ‘block’ to problem solving
Incubation
A problem is solved more easily if set aside for some time
Algorithm
Systematic procedure guaranteed to lead to a solution
Heuristics
Rules of thumb that generally lead to a solution
Brute force search
Test all possible states until solution found
Hill climbing
All moves towards the goal state
Working backward
Approaching problem from goal state
Means ends strategy
Identifies distance between current state and goal state
Positive and negative transfer
Previous experience either allows problem to be solved faster or disrupts the ability
Multi constraint theory
Predicts how people use analogies
Predicts what factors govern thee analogies
Problem similarity, problems structure, purpose of analogy
