問題解決に及ぼす下位目標の提示形態の効果

抄録

The present study examined the effects of different forms of subgoal presentation on problem solving (The Tower of Hanoi problem). Subjects solved the training task with some subgoals. There were two types of training tasks in which the presentation form of subgoals varied as follows: 1) Subjects were presented all subgoals simultaneously, and these subgoals were not removed until the subjects reached the final goals (simultaneous presentation and non removal: Group SP-NR); 2) Subjects were presented subgoals successively, these being removed when subjects reached each subgoal (successive presentation and removal: Group SP-R). Subjects were divided into either of the above mentioned training task conditions. Following the training task, subjects were to solve either of two different test tasks (one was identical with the training task, the other was a varied task) without subgoals presented. The results showed that Group SP-NR solved the test task faster than Group SP-R. The finding suggested that the effects of presenting subgoals depended on the form of presentation of subgoals.
