Document Summary
Psyc 213 problem solving ii and cognitive disorders. Classic problem solving test: orcs and hobbits problem. 11 steps to get 3 orcs and 3 hobbits across a river in a 2 orc/hobbit boat without having more orcs than hobbits on one side or the other. Problem shows that we often solve problems in a step by step but non-linear fashion (back and forth) 3) operators (actions used to change states) Going between states (back and forth, non linear) Newell and simon: invented gps computer program. First human simulation of problem solving: analogy between computer models and how we solve things. Viewed as projection system: problems are about choosing between pairs of statements. It"s plan oriented, setting up goals and subgoals in series of steps. Provides insight into problem solving goals and protocols. Problem space often represented by search tree which shows all different paths that could be taken. Systematic algorithms: all possible moves from initial state of the problem.
