之前关于视觉工作记忆（VWM）的研究主要研究了单个时刻呈现的数组的记忆。在这里，我们检查了间隔为 1,100 毫秒的两个阵列的 VWM。我们重点关注将 VWM 容量分配给两个阵列，作为插入到它们之间的动态事件的函数。在间隔期间，不相关的点移动形成三种类型的运动：(1) 连接阵列 1 和 2 的连贯（表观）运动，(2) 跳跃运动，或 (3) 具有两个断开连接的段的连贯运动。结果表明，阵列 2 位置的 VWM 优于阵列 1，特别是当阵列通过相干运动连接时。我们建议两个时间上不同的阵列之间的连贯运动将阵列连接成单个视觉事件。然后，VWM 会偏向于记住事件的最新状态。
Previous studies on visual working memory (VWM) have primarily investigated memory for an array presented for a single moment. Here, we examined VWM for two arrays separated by a 1,100-msec interval. We focused on the allocation of VWM capacity to the two arrays as a function of dynamic events inserted between them. During the interval, irrelevant dots moved to form three types of motion: (1) coherent (apparent) motion that connected Arrays 1 and 2, (2) jumpy motion, or (3) coherent motion with two disconnected segments. Results showed that VWM for Array 2's locations was better than for Array 1's, especially when the arrays were connected by coherent motion. We suggest that coherent motion between two temporally disparate arrays connects the arrays into a single visual event. VWM is then biased toward remembering the more recent state of the event.
