情绪对连续事件定向遗忘的影响
摘要
<p id="C2">Forgetting is an adaptive process that can limit the interferences from irrelevant distractors and update valuable information. With regard to negative events, intentional forgetting can effectively help us to recover from trauma. The research on the intentional forgetting of emotional information usually adopts the directed forgetting paradigm. The better memory performance of R items relative to F items is referred to as the typically directed forgetting effect. Although emotional information is thought to be easier to remember than neutral information because of the attentional capture and elaborative process, whether emotional information is more resistant to forgetting is obscured. Most studies on emotional directed forgetting used various discrete items, such as words and pictures, and few addressed continuous events that are actually common in our episodic memory. Directed forgetting is not an all-or-nothing phenomenon because specific and general information appears to be forgotten at different rates. Therefore, this study aims to investigate the influence of emotions on the directed forgetting effect of continuous events. This study also explores the differences in forgetting rates between general/gist memory and specific memory.<br/>In the present study, we adopted the event directed paradigm that embeds memory instructions into continuous videos. In experiment 1, 36 participants were equally divided into two groups: one group watched a neutral video, and the other group watched a negative one. Each video contained nine R segments and nine F segments that were surrounded by green and purple borders. The colored borders acted as memory instructions. The participants were asked to remember the video segments when the border was green and to forget the video segments when the border was purple. The test phase involved free recall and recognition. The participants were requested to recall all information about the video regardless of the classificat
