中文摘要：

自Luck等人的研究以来，诸多研究者对客体信息在视觉工作记忆中的表征与存储问题进行了探讨。现有研究主要采用呈现于静态场景的客体作为刺激材料，而不涉及对客体运动特征信息的短时存储。本研究结合多客体追踪范式和视觉工作记忆的变化觉察范式，通过比较检测项全部呈现方式与单检测项呈现方式条件下，客体运动速度的视觉工作记忆绩效，探讨了多个客体的运动速度信息在工作记忆中的存储方式和容量问题。结果表明，在工作记忆中能够存储约3仑独立客体的运动速度信息。

英文摘要：

Following the classical research of Luck et al. , many researchers have explored the mechanism of representation and storage of visual objects in working miemory. However, most of current researches adopted the static object as the experimental stimulus, and the short-term storage of motion information of objects has been rarely discussed. By combining multiple object tracking and changing detection paradigms, the present research compared the performances of memory tasks in the whole-display test and the single-probe test to investigate the storage mechanism and capacity of moving-speed information of multiple objects in visual working memory. The results indicated that the moving-soeed information of 3 obiects could he retained within it.
