Recent research has shown that objects near the hands receive preferential visual processing. However, it is not known whether proximity to the hands can affect executive functions. Here we show, using two popular paradigms, that people exhibit enhanced cognitive control for stimuli that are near their hands: We observed reduced interference from incongruent flankers in a visual attention task, and reduced costs when switching to an alternative task in a task-switching paradigm. The results reveal a remarkable influence of posture on cognitive function and have implications for assessing the potential benefits of working on handheld devices.
最近的研究表明，手部附近的物体受到优先的视觉处理。然而，尚不清楚与手部的接近程度是否会影响执行功能。在此，我们使用两种常见范式表明，人们对靠近手部的刺激表现出增强的认知控制：在视觉注意力任务中，我们观察到来自不一致侧翼刺激的干扰减少；在任务切换范式中，切换到另一个任务时成本降低。这些结果揭示了姿势对认知功能的显著影响，并对评估使用手持设备工作的潜在益处具有启示意义。
