Representations in visual working memory (VWM) influence attention and gaze control in complex tasks, such as visual search, that require top-down selection to resolve stimulus competition. VWM and visual attention clearly interact, but the mechanism of that interaction is not well understood. In the research reported here, we demonstrated that in the absence of stimulus competition or goal-level biases, VWM representations of object features influence the spatiotemporal dynamics of extremely simple eye movements. The influence of VWM therefore extends into the most basic operations of the oculomotor system.
视觉工作记忆(VWM)中的表象会影响复杂任务中的注意力和眼球控制,例如视觉搜索,这些任务需要自上而下的选择来解决刺激竞争。VWM 和视觉注意力显然会相互作用,但这种相互作用的机制还不是很清楚。在本研究中,我们证明了在没有刺激竞争或目标水平偏向的情况下,物体特征的 VWM 表示会影响极简单眼球运动的时空动态。因此,VWM 的影响延伸到了眼球运动系统的最基本操作中。
