Problem 7 - Solving And Creativity Flashcards
Problem solving strategies: algorithm
- Always produces a solution to a problem.
- Exhaustive search: try all possible answers.
- Inefficient and unsophisticated.
Heuristics: the analogy approach
- used everyday
- you employ a solution to a similar, early problem to help you solve the new problem
- anaphoric reference: connects an anaphor with its referent
Structure of the analogy approach
- problem isomorphism: set of problems that have the same underlying structures and solutions but different specific details.
- people focus on superficial content rather than underlying meaning (abstract)
- failure to transfer knowledge (when dressed up in superficially different cover stories)
- those with limited problem-solving skills and metacognitive abilities have difficulty using analogies
Conditions under transfer (analogy approach)
- diagrams and general principle statements did not help to apply analogies.
- relating and reading two analogous stories helps transfer of knowledge.
- connections between two different problems => schema induction
Schemas (analogy approach)
- mental representation of facts and procedures that apply to a specific object/situation
- mental representation of the underlying principle that multiple problems share.
- schemas used to solve analogous problems.
Steps:
1. Noticing relationship between two problems. (Failure occurs often here)
2. Mapping key elements
3. Schema development
Surface vs structural features (analogy approach)
- ability to notice, map and develop schemata depends on type of similarity.
- surface features: specific elements (if problems share these, part of the problem looks similar)
- structural features: underlying relationships (if structurally similar, different on the surface)
- Verbalizing problems => noticing structural features.
- kinesthetic information: information arises from body movement can help encode structural features.
Factors for appropriate use of analogies
- people often overcome context and use analogies appropriately.
- solving structurally similar problems before tackling the target problem is easier.
Problem solution: dual processes revisited (analogy approach)
- involving system 1 and 2 processing
- preferred method can depend not only on the situation but also on your level of knowledge and experience
The means-ends heuristic
- You divide the problem into a number of subproblems.
- You reduce the difference between initial state and goal state for each of the subproblems.
- most effective and flexible problem-solving strategies
Research on the means-ends heuristic
- WM is especially active when planning one of these movement sequence within subproblems
- people are reluctant to move away from goal state when they are required to do so.
The hill-climbing heuristic
- straightforward strategy
- useful when not enough information about alternatives - you see immediate next step
- can lead you astray
- drawback: consistently choose the alternative that appears to lead most directly to the goal.
- short-term goals/solutions
Individual differences: cross-national comparisons in problem solving strategies
Different cultures emphasize different aspects (planning is for US, Germany for ex)
Ill-structured problems and the role of insight
- they do not have well defined problem spaces
- difficulty constructing appropriate mental representations for modeling these problems and their solutions.
- domain knowledge and justification skills are important.
- cognitive and affective factors (attitudes and regulation) are also important.
Insight problems
- distinctive and sometimes sudden
- looking at the problem in a different way.
- involves reconceptualizing a problem in a new way.
- involves detecting and combining relevant old and new information for a novel view.
Early gestaltist views (insight problems)
- perceive the problem as a whole
- productive thinking: go beyond the bounds of existing associations.
- reproductive thinking: existing associations involving what is already known
The neo-gestaltist view (insight problems)
- Routine problems: quick to find solution
- Insight problems: poor ability to find solution and pessimistic view
Insights into insights
- insights: occur gradually and incrementally over time.
- sleep increases likelihood of insight production.
- either brilliant or wrong
Neuroscience and insight
Mental sets, entranchment and fixation
- mental sets (frame of mind of existing model representing a problem, context or procedure) can hinder problem solving.
- you fixate on a strategy that usually works.
- influences the solution of routine problems
- functional fixedness: inability to realize something can be used for other functions than its normal one.
- stereotypes are used to overgeneralize solutions.
Negative and positive transfer
- transfer is the carryover of knowledge/skills from one problem to another.
- negative transger: early problems make it hard to solve a later one.
- positive transfer: early problem makes it easier to solve a later one.
Transfer of analogies
- positive transfer involving analogies
- when domain/context of two problem is similar = more likely to apply analogies
- be guided/look for analogies to find them
Intentional transfer: searching for analogies
- must perceive the relationships between them (content attributes are irrelevant)
- similarity does not matter but closely related structural systems of relationships does.
- transparency: you see analogies when they dont exist because of similarity of content = negative transfer of isomorphic problems.
Needing Inhibitory control to creating creative solutions - aims
- aim 1: to determine the potential role of inhibitory control in creative idea generation
- aim 2: to determine whether creative idea generation depends specifically on the ability to inhibit fixation effects, dual task costs under a secondary working memory task.
Needing Inhibitory control to creative - experiment
- experiment 1: dual task paradigm (creating solutions for the egg while doing the color word stroop task)
- experiment 2:
Needing Inhibitory control to creative - results
- experiment 1: inhibitory control load decreased creative capabilities in terms of fluidity and expansivity.
- experiment 2: WM load had no significant effect on creative ideation
- Overall: inhibitory control is a core process to overcoming fixation effects and generating original solutions in a creative task.
