摘要
通过两个实验,探讨空间工作记忆负载对中央注视线索引发返回抑制(inhibition of return,IOR)的影响。实验一通过再认面孔的相似度来控制与中央注视线索相关的空间工作记忆任务负载,结果发现,高任务负载条件下出现IOR,低任务负载条件下中央注视线索促进搜索;实验二在实验一高任务负载的基础上加入与注视线索无关的空间工作记忆任务,结果发现,仅在与注视线索无关的空间工作记忆负载低的条件下出现IOR。结果表明,中央注视线索引发的IOR受到空间工作记忆资源的限制,中央注视线索只有在获得足够的资源时才能引发IOR。注视线索获得空间工作记忆资源多少决定中央注视线索能否引发IOR。
Two experiments were conducted to explore the influence of spatial working memory（SWM） load on inhibition of return（IOR） elicited by central gaze cue. In experiment 1,the cue relevant SWM load was manipulated by changing the similarity between the recognition and memory faces. The results showed that IOR was observed when the cue relevant SWM load was high,while no IOR was observed under low SWM load condition. Experiment 2 was conducted based on the condition that IOR was elicited by central gaze cue in experiment 1,and an additional cue irrelevant SWM task was presented before the gaze cue. The results showed that IOR was observed when the cue irrelevant SWM load was low,while IOR disappeared when the load was high. Taken together,our results revealed that IOR elicited by central gaze cue could be mediated by SWM resources. Whether IOR be elicited by central gaze cue may depend on the degree to which SWM resources was allocated to central gaze cue.
