Abstract

記銘項目が実験者によって割り当てられる場合よりも,実験参加者自身により選択される場合のほうが記憶保持は優れる(自己選択効果).本研究は,選択時における選択項目と非選択項目の両方を短期記憶に保持する過程が後の再生を促進するために必要十分であるのか,それとも短期記憶保持された選択肢間を比較する過程が必要であるかを検討した.実験1では,選択段階で選択項目のみを短期記憶に保持する強制選択条件,選択項目と非選択項目を保持する遅延選択条件,保持された選択肢間での比較を行う比較選択条件と自己選択条件を設けた.選択項目の再生率は前の2条件間では差がなかったが,後の2条件は前の2条件よりも有意に高かった.よって,選択時に短期記憶に保持された選択肢を互いに比較する過程が再生の促進に重要である可能性が示唆された.実験2では,意味的な基準での比較と非意味的な基準での比較による再生成績の違いが認められなかったことから,実験1の比較選択条件での再生の促進が意味処理のみで説明される可能性は低いと考えられた.

The self-choice effect states that self-selected items are more likely to be remembered than items selected by an experimenter. This study examines whether the mere short-term retention of items during selection is sufficient or whether a comparison among items is required for the self-choice effect to manifest itself. In Experiment 1, during each selection, participants were assigned to one of four conditions; a forced-choice condition (only retain instructed item in short-term memory), a delayed-choice condition (retain all items in short-term memory), a compared-choice condition, and a self-choice condition. The recall rates of chosen items in the first two conditions showed no differences, but they were lower in the second two conditions. These results indicate that comparisons among items during the selection are necessary to facilitate later recall. In Experiment 2, both semantic and non-semantic comparison criteria failed to produce different recall rates. Thus, it is difficult to explain the facilitated recall rate within the compared-choice condition merely by semantic processing.
