他人在场条件下的社会分享型提取诱发遗忘
摘要
<p id="C2">In our daily life, people have plenty of opportunities to share their memories of past experience or knowledge with others. In such conversation, the phenomenon which, due to conscious or unconscious selective retrieval of speakers, listeners forget the unmentioned but relevant memories, is called socially shared retrieval-induced forgetting (SS-RIF). Based on previous research of the phenomenon, the current study focuses on the influence of bottom-up processing of social interactive situations and top-down cognitive control of inhibition on SS-RIF, investigating whether the presence of speaker or not, and the listener's ability of various types of inhibition control would affect the occurrence and scale of SS-RIF. <p id="C201">In Experiment 1, a 2 (interactive level: the presence of the speaker, the absence of the speaker) × 2 (interactive role: speaker, listener) × 4 (item types: Rp+, Rp-, Nrp+, Nrp-) mixed design was adopted, in which interactive level was the between-participants design while interactive role and item type were the within-participants design. The dependent variable was the correct recall proportion in the final recall test. A total of 116 healthy volunteers participated in Experiment 1. They were randomly assigned to different interactive level conditions. All participants of Experiment 1 were recruited in Experiment 2 to explore the effect of different types of inhibitory control on socially shared retrieval-induced forgetting in different experimental conditions. <p id="C203">It was found in Experiment 1 that, regardless of condition, the phenomenon of within-individual retrieval- induced forgetting in speakers appeared; however, the socially shared retrieval-induced forgetting in listeners only arose in the presence of the speaker condition. Furthermore, Experiment 2, carried out on the basis of Experiment 1, showed that the effect of socially shared retrieval-induced forgetting was independent from levels of inhibitory control. In
