摘　　要：采用相对新近性判断范式(judgments of relative recency),通过三个实验探讨了工作记忆中时序信息和空间信息的存储方式及其关系。实验一比较了有无空间线索两种条件下时序信息的记忆绩效,结果发现,有无空间线索并不影响对时序信息的记忆。实验二和实验三通过控制刺激呈现的视野范围和减少呈现位置的不确定性来利化空间线索,结果表明,时序信息的记忆绩效也不受空间线索的影响。由此推论,工作记忆中的时序信息和空间信息是分离编码存储的,加入空间线索并不能提高时序信息的记忆绩效。This research explores the storage of temporal order information and spatial information in working memory with the paradigm of judgments of relative recency. The first experiment compared the subjects＇ memory for temporal order information under the condition with and without spatial cues. The result demonstrated that the spatial cue had no effect on the memory performance. In the second and third experiments,we reduced the size of the stimuli as well as the field of vision, and further reduced the uncertainty of spatial information, so as to benefit the spatial cues. However, the results pattern was still the same. Therefore ,we infer that temporal order information and spatial information are encoded and stored separately in working memory, so that adding spatial cue cannot improve the memory performance of temporal order.
