研究证实，身体影响感知，但对注意力的体现知之甚少。我们研究了他人的暗示行为是否直接引起空间注意，使用了一个带有非预测性中央线索的横向隐蔽定向任务，描绘了静止的、朝右/向左的身体在动作中保持平衡。效度效应（有效提示试验的反应时间比无效提示试验的反应时间短）表明受试者倾向于隐含动作的方向。在实验1中，我们比较了动作（跑步、投掷）和非动作（站立）线索。只有行动线索产生效度效应，表明暗示的行动引导注意力。总的来说，动作线索产生的反应更快，这表明动作线索启动了运动反应。在实验2中，我们确定了动作线索是否将注意力转移到特定方向，而不是空间的一般一侧：两个线索具有相似的动作速度和运动努力，但在隐含方向（跳跃，垂直，投掷，水平）上不同。只有暗示运动方向与侧边目标位置一致的投掷线索才存在效度效应。在实验3中，我们比较了块状刺激和投掷动作刺激，以检验较低水平的知觉信息是否可以单独解释注意效应。效度效应只存在于人的行为刺激。总体而言，研究结果表明，行动的预测性模拟将注意力转移到与行动一致的方向。
Research confirms that the body influences perception, but little is known about the embodiment of attention. We investigated whether the implied actions of others direct spatial attention, using a lateralized covert-orienting task with nonpredictive central cues depicting static, right/left-facing bodies poised in midaction. Validity effects (decreased response times for validly compared with invalidly cued trials) indicated orienting in the direction of the implied action. In Experiment 1, we compared action (running, throwing) with nonaction (standing) cues. Only the action cues produced validity effects, suggesting that implied action directs attention. The action cues produced faster responses overall, suggesting that action cues prime motor responses. In Experiment 2, we determined whether action cues shifted attention in a specific direction rather than to a general side of space: Two cues had similar action speed and motor effort but differed in implied direction (jumping, vertical; throwing, horizontal). Validity effects were found only for the throw cues for which the implied motion direction was consistent with lateralized target locations. In Experiment 3, we compared block-like stimuli to the throwing action stimuli to examine whether lower level perceptual information could account for the attention effects alone. Validity effects were found only for the human-action stimuli. Overall, the results suggest that predictive simulations of action shift attention in action-consistent directions.
