The present study examined how the size of attended area affects the repulsion of perceived object location from the focus of attention reported previously (attentional repulsion effect). We induced sustained changes in the size of attentional focus and tested the impact of this experimental variation on the perception of object location. The results of three experiments revealed reliable repulsion effects for each size of attentional focus. However, the magnitude of the effect decreased substantially with an increase in focus size. This outcome extends the knowledge about how spatial attention affects visual perception.

注意焦点的大小调节对物体位置的感知

本研究检查了参与区域的大小如何影响从先前报道的注意力焦点感知到的物体位置的排斥（注意排斥效应）。我们诱导了注意力焦点大小的持续变化，并测试了这种实验变化对物体位置感知的影响。三个实验的结果揭示了每个注意力焦点大小的可靠排斥效应。然而，随着焦点尺寸的增加，效果的幅度显着下降。这一结果扩展了关于空间注意力如何影响视觉感知的知识。
