The present study explored the origin of perceptual changes repeatedly observed in the context of actions. In Experiment 1, participants tried to hit a circular target with a stylus movement under restricted feedback conditions. We measured the perception of target size during action planning and observed larger estimates for larger movement distances. In Experiment 2, we then tested the hypothesis that this action specific influence on perception is due to changes in the allocation of spatial attention. For this purpose, we replaced the hitting task by conditions of focused and distributed attention and measured the perception of the former target stimulus. The results revealed changes in the perceived stimulus size very similar to those observed in Experiment 1. These results indicate that action’s effects on perception root in changes of spatial attention.

行动通过调节注意力来影响知觉

本研究探讨了在行动的背景下反复观察到的知觉变化的起源。在实验1中,参与者试图在受限的反馈条件下用手写笔移动圆形目标。我们在行动计划期间测量了对目标大小的感知,并观察到较大移动距离的较大估计值。在实验2中,我们然后检验了这一假设,即这种对感知的特定动作影响是由于空间注意力分配的变化而引起的。为此,我们用集中注意力和分散注意力的条件代替了击球任务,并测量了对先前目标刺激的感知。结果表明,感知刺激大小的变化与实验1中观察到的变化非常相似。
