We examined the effect of expanding and contracting motion on visual short-term memory (VSTM) by using a change-detection task. One, three, five, or seven expanding or contracting line segments were presented on memory and test displays. The test display was either identical to the memory display or contained a line segment with a different orientation from that in the memory display. The participants were asked to indicate whether the orientation of the line segments changed between the two successive displays. The results showed that the capacity of VSTM for expanding motion was larger than that for contracting motion (Experiment 1). Moreover, in Experiment 2, the capacity of VSTM for expanding motion was superior when the retention interval between the memory and test displays was 400ms. In contrast, under retention intervals of longer than 800ms, VSTM capacity for contracting motion was superior. These results suggest that the effect of expanding and contracting motion on VSTM varies depending on the retention interval.
