“后延时”对幼儿事件性与活动性预期记忆影响的实验研究

本研究通过实验法、访谈法了解了学前儿童事件性及活动性预期记忆的年级效应及“后延时”对它的影响。结果表明，3岁之前，幼儿的事件性及活动性预期记忆能力就已经有了一定的发展，但是3—6岁仍然是幼儿这方面能力发展的关键时期。“后延时”对幼儿事件性及活动性预期记忆具有一定影响，但影响不大。如果提高幼儿预期记忆进行中任务的难度或者提供适当的外部提示物应该能将预期记忆任务的“延时效应”凸现出来。

The Experiments about the Influence of ＂Time- Lapse＂ on the Infant＇s Event- based and Activitybased Prospective Memory

Using the methods of experimentation and interview, we investigated the influence of the time - lapse＇and grade on infant＇s eventbased and activity -based prospective memory. The results show： the infant＇s event -based and activity -based prospective memory all have been developed before 3 years old. But it still a pivotal period during 3 - 6 years old.. The influence of the ＂time - lapse＂ on infant＇ s event - based and activity - based prospective memory is small. But if we increase the difficuty of the on - going tasks or provide proper external cues, the influence will be bigger.
