刺激リストの感情価が指示忘却に及ぼす影響

リスト間での検討

抄録

Effects of the emotional valence of words on directed forgetting were investigated using the list method. In the Experiment 1, Participants studied Lists 1 and 2, both consisting of emotionally positive, negative, or neutral words. In Session 1, participants received the "Forget Instruction," telling them to forget List 1 and remember List 2 (forget-condition). Then, they were asked to recall all the words in the two lists, including those that they were instructed to forget. In Session 2, participants received the "Remember Instruction" telling them to remember both Lists 1 and 2 (remember-condition). Then, they were told to recall all the list words. The order of the session was counterbalanced across participants. Results provided evidence for the directed forgetting effect: participants in the forget-condition recalled fewer List 1 words and more List 2 words compared to the remember-condition. However, this effect was not observed when the study-list was negative List 1 and positive List 2, negative List 1 and neutral List 2. Similar results were obtained in Experiment 2, using the same procedure, with the exception that neutral words were eliminated. These findings suggest that the emotional valence of the list modulated the magnitude of the directed forgetting effect.
