情绪刺激对前瞻记忆的影响

使用情绪图片作为背景任务刺激,通过两个实验来考察积极情绪和消极情绪对时间性和事件性前瞻记忆的影响。结果发现,对于背景任务的反应时,在时间性前瞻记忆和事件性前瞻记忆中,情绪的主效应都显著。而对于前瞻任务的正确率,在两种前瞻记忆中,情绪的主效应都不显著。将两个实验的数据合并分析发现,对于前瞻任务的正确率,任务类型的主效应显著,即时间性前瞻记忆的成绩显著高于事件性前瞻记忆; 而情绪的主效应不显著。结果表明,背景任务中不同的情绪刺激会对个体完成背景任务的速度产生影响,而对前瞻记忆任务的执行不会产生影响。

The Impact of Emotional Stimulus on the Prospective Memory

Abstract:Using affective pictures as the stimulus of ongoing task,the present research explored the effects of positive emotion and negative emotion on prospective memory through two experiments.The results showed that,for the reaction time(RT)of ongoing task in both time-based prospective memory and event-based prospective memory,the main effect of emotion was significant.For the accurate rate of prospective memory in both tasks,the main effect of emotion was not significant.Combining the data of the two experiments,we found that for the accurate rate of prospective memory,the main effect of task type(time-based vs.event-based prospective memory)was significant,that is,the prospective memory performance in time-based prospective memory was better than event-based prospective memory.The main effect of emotion was not significant.These results suggests,the different emotional stimulus of ongoing task influenced the performance velocity of ongoing task,but didn't affect the accurate rate of prospective memory.
