采用动态搜索任务,系统改变刺激项位置变换的速度,探讨视觉搜索是否有"记忆"参与.结果发现:(1)刺激项位置的变换速度较快时(120 ms/次、220 ms/次),动态搜索的搜索效率显著低于静态搜索;(2)刺激项位置的变换速度较慢时(420 ms/次),动态搜索的搜索效率与静态搜索无差异.该结果表明视觉搜索有"记忆"参与,返回抑制可能是视觉搜索中"记忆"的内在机制. |

The present study explored the role of memory in visual search with the dynamic search paradigm. The results showed that (1) when search items randomly exchanged their locations every 120 ms or 220 ms, the efficiency of dynamic search was significantly lower than static search; (2) when search items randomly exchanged their locations every 420 ms, the search efficiency difference between dynamic search and static search was not significant. The results suggest that visual search involves memory and inhibition of return might play a role in visual search. |
