PSYCH 240 Lecture 17: Psych 240 Lecture 17 - Problem Solving Continued
Document Summary
Insight problems: answer comes in a sudden ash and doesn"t involve a lot of computation. !1 (1) explained by mental set effects, taking a break allows for existing set. Insight and non-insight problems: metcalfe and wiebe. Insight a) triangle problem and chain problem: problems solved suddenly, non-insight, algebra problems, solved gradually, expertise in problem solving, rich, organized schemas, well-organized declarative and procedural knowledge, more sophisticated representations, spend more time on representation. 1. take longer to start on solution, but less time to complete it: less means-end analysis, pre-stored solutions in long term memory. 2. fewer demands on working memory: move forward, not backward. Issues with expert problem solving techniques: chess example, expert memory was no better than ordinary people, memory for random con gurations slightly worse than beginners, hindered by schemas, memory for meaningful con gurations much better than beginners. Improvement: diminishes with time, takes a very long time to gain small amount of improvement.
