The current study explored effects of continuous hand motion on the allocation of visual attention. A concurrent paradigm was used to combine visually concealed continuous hand movements with an attentionally demanding letter discrimination task. The letter probe appeared contingent upon the moving right hand passing through one of six positions. Discrimination responses were then collected via a keyboard press with the static left hand. Both the right hand's position and its movement direction systematically contributed to participants' visual sensitivity. Discrimination performance increased substantially when the right hand was distant from, but moving toward the visual probe location (replicating the far-hand effect, Festman et al., 2013). However, this effect disappeared when the probe appeared close to the static left hand, supporting the view that static and dynamic features of both hands combine in modulating pragmatic maps of attention.
当前研究探索了连续手部运动对视觉注意分配的影响。采用并发范式将视觉隐蔽的连续手部运动与注意力要求高的字母辨别任务结合起来。当移动的右手穿过六个位置之一时，字母探针就会出现。然后，通过静态左手的键盘按压收集辨别反应。右手的位置及其运动方向都系统地影响参与者的视觉敏感性。当右手远离但向视觉探针位置移动时（复制了 Festman 等人，2013 年的远手效应），辨别性能会显著提高。然而，当探针出现在靠近静态左手的位置时，这种效果消失了，这支持了双手的静态和动态特征结合起来调节注意力实用地图的观点。
