A simple button press towards a prime stimulus enhances subsequent visual search for objects that match the prime. The present study investigated whether this action effect is a general phenomenon across different task domains, and the underlying neural mechanisms. The action effect was measured in an unspeeded size-matching task, with the presentation of the central target and the surrounding inducers of the Ebbinghaus illusion together to one eye or separately to each eye, and when repetitive TMS was applied over right primary motor cortex (M1). The results showed that a prior key-press significantly reduced the illusion effect compared to passive viewing. Notably, the action effect persisted with dichoptic presentation of the Ebbinghaus configuration, but disappeared with the right M1 disruption. These results suggest that action guides visual perception to influence human behavior, which mainly affects the late visual processing stage and probably relies on feedback projections from the motor cortex.
只需简单按下按钮朝向主导刺激，就能增强后续对与主导刺激相匹配的视觉目标的搜索。本研究旨在调查这种动作效应是否是不同任务领域中的普遍现象，以及潜在的神经机制。在非快速大小匹配任务中测量了动作效应，中央目标和艾宾浩斯错觉的诱导同时呈现给一只眼睛，或分别呈现给每只眼睛，当重复经颅磁刺激（TMS）施加于右侧初级运动皮层（M1）时。结果表明，与被动观看相比，预先按键显著降低了错觉效应。值得注意的是，双眼呈现艾宾浩斯错觉的配置时，动作效应仍然存在，但右侧 M1 受到干扰时，动作效应消失。这些结果表明，动作可以引导视觉感知，从而影响人类行为，这主要影响后期视觉处理阶段，可能依赖于来自运动皮层的反馈投射。
