This study examined the modulation of retention interval in the effect of emotion as elicited from negative and positive arousing pictures on recognition memory. Participants underwent seven encoding sessions and one testing session. The encoding sessions were separated by certain lengths of intervals such that there were seven levels of time gaps between encoding and testing. In each encoding session, participants learned a list of 30 pictures (including 10 neutral, 10 positive and 10 negative pictures). In the testing session, they were presented with a list of 210 old and 210 new pictures and made "old/new" and "remember/know" judgements. The results showed that negative arousing pictures enhanced overall recognition in the 2-week interval and enhanced recollection in both the 2-week and 3-week intervals. However, neither negative nor positive arousing pictures had any effect on familiarity regardless of retention interval. The current study contributes to the literature by suggesting that longer retention intervals do not necessarily lead to more pronounced effects of negative arousing pictures and that the modulation of retention interval depends on the specific components of recognition memory.
本研究考察了从消极和积极唤起性图片引发的情绪对识别记忆的影响中，保持间隔的调节作用。参与者进行了七次编码会话和一次测试会话。编码会话之间间隔一定长度的时间，使得编码和测试之间存在七个时间间隔水平。在每次编码会话中，参与者学习一组30张图片（包括10张中性图片、10张积极图片和10张消极图片）。在测试会话中，向他们呈现一组210张旧图片和210张新图片，并做出“旧/新”和“记得/知道”判断。结果表明，消极唤起性图片在2周间隔内增强了总体识别，在2周和3周间隔内增强了回忆。然而，无论保持间隔如何，消极和积极唤起性图片对熟悉度均无任何影响。本研究通过表明较长的保持间隔不一定会导致消极唤起性图片产生更显著的影响，且保持间隔的调节取决于识别记忆的特定成分，为该文献做出了贡献。
