The Capacity of Visual Working Memory for Motion Direction of Objects

To memorize both feature and spatiotemporal information of moving objects is a critical human activity.Much research has been done to explore the storage of visual information from a static scene in working memory and to investigate how visual information is dynamically updated in a multiple object tracking task;however,the storage of motion information of multiple objects in working memory has been rarely discussed.By combining multi-object tracking and change detection paradigms,with individual moving objects as stimuli,the present research investigated the capacity of visual working memory for moving objects and the results indicated that about 3 objects can be retained in visual working memory.
