協同問題解決における他者を介した情報取得の効果

摘要

本研究では，協同問題解決において．他者を介して情報を取得することの効果について，実験的な検討を行った．実験の結果から，（1）他者を介した仮説の取得は，仮説評価の段階において評価時間を増加させる一方で，（2）仮説生成の段階に効果を与えることはなく．問題解決のパフォーマンスに影響を及ぼさないことが示された．%In this study, we investigated effects of information acquisition through a partner in collaborative problem solving. In the experiment, an insight problem that participants met an impasse since some constraints prevent them from reaching a solution was used as an experimental task. To find the solution, they needed to realize an irrelevant problem space where they are captured. Two conditions were set up: (1) the solo condition that the participants evaluated a rejected hypothesis of their own hypothesis during solving problem; and (2) the pair condition that they evaluated same hypothesis as a partner's hypothesis. The experimental results showed that information acquisition through a partner did not influence hypothesis generation process though evaluation time for the hypothesis increased.
