An eye tracking paradigm was used to investigate how infants' attention is modulated by observed goal-directed manual grasping actions. In Experiment 1, we presented 3-, 5-, and 7-month-old infants with a static picture of a grasping hand, followed by a target appearing at a location either congruent or incongruent with the grasping direction of the hand. The latency of infants gaze shift from the hand to the target was recorded and compared between congruent and incongruent trials. Results demonstrate a congruency effect from 5 months of age. A second experiment illustrated that the congruency effect of Experiment 1 does not extend to a visually similar mechanical claw (instead of the grasping hand). Together these two experiments describe the onset of covert attention shifts in response to manual actions and relate these findings to the onset of manual grasping.
采用眼动追踪范式来研究婴儿的注意力是如何被观察到的目标导向的手动抓取动作所调节的。在实验 1 中，我们向 3、5 和 7 个月大的婴儿展示了一只抓取手的静态图片，然后在与手的抓取方向一致或不一致的位置出现目标。记录婴儿从手到目标的注视转移潜伏期，并在一致和不一致的试验中进行比较。结果表明，从 5 个月大开始就存在一致性效应。第二个实验表明，实验 1 的一致性效应并不扩展到视觉上相似的机械爪（而不是抓取手）。这两个实验共同描述了对手动动作的隐蔽注意力转移的开始，并将这些发现与手动抓取的开始联系起来。
