PSYC*2140 Study Guide - Final Guide: Problem Solving, Backtracking, Working Memory
Document Summary
Problem solving techniques: generate and test technique, means-end analysis, working backward or backtracking, reasoning by analogy. Problem solving techniques: generate and test technique, generate solutions and test solutions, useful if there is a limited number of possibilities, not useful if, too much possibilities, no guidance over generation, can"t keep track of possibilities tested, ex. Newell and simon 1972: problem space: initial state, conditions at beginning of problem, ex. Look at question: goals state, conditions at end of problem, ex. Answering question: intermediate states, various conditions that exist along pathways between initial and goal state, ex. Every step to answer question: operators, permissible moves, ex. You know what the desk is supposed to look like. But there are a lot of pieces to finish it. Intermediate is the instructions: working backward or backtracking, create sub-goals and reduce differences between current state and goal state (like means-analysis, but sub-goals are created working backwards from goal state, ex.
