根据对感知的具体行动解释，感知者的行动能力会影响对环境的感知。例如，在一个基于计算机的任务中，当参与者使用较小的网时，他们认为鱼移动得更快，因此捕获鱼的效率较低（Witt & Sugovic, 2013）。在这里，我们通过要求参与者参与一项次要任务来检验注意力对感知判断的影响程度，该任务将他们的注意力引向（实验1）或远离（实验2）要捕获的鱼。尽管感知鱼速受到被试捕获性能的影响，但注意分配不影响捕获性能和感知鱼速之间的关系。研究结果表明，动作直接影响空间知觉，而不是通过注意过程产生间接影响。
According to the action-specific account of perception, a perceiver’s ability to act influences how the environment is perceived. For example, in a computer-based task, participants perceive fish as moving faster when they use a smaller net, and are thus less effective at catching the fish (Witt & Sugovic, 2013a). Here, we examined the degree to which attention may influence perceptual judgments by requiring participants to engage in a secondary task that directed their attention either toward (Exp. 1) or away from (Exp. 2) the to-be-caught fish. Though perceived fish speed was influenced by participants’ catching performance—replicating previous results—attentional allocation did not impact this relationship between catching performance and perceived fish speed. The present results suggest that action directly influences spatial perception, rather than exerting indirect effects via attentional processes.
