本研究调查了 7 个月大婴儿在感知抓握动作时注意力定向的可塑性。先前的研究表明，当婴儿观察抓握的手时，他们的注意力会沿着抓握的方向转移，这表明该方向存在可靠的启动效应。这种启动效应背后的机制很大程度上是未知的，也不清楚这种启动效应对于短暂接触新的行动目标突发事件有多大的可塑性。在空间提示范例中，我们在一系列测试试验之前提出了一系列训练试验。这些训练序列显着调节了婴儿的注意力。这表明，当通过注意力转移进行评估时，动作感知不仅仅基于婴儿的抓握经验，而且会迅速适应特定环境中观察到的规律。
The present study investigates the plasticity of 7-month-old infants' orienting of attention during their perception of grasping actions. Previous research has shown that when infants observe a grasping hand, they shift their attention in line with the grasping direction, which is indicated by a reliable priming effect in this direction. The mechanisms behind this priming effect are largely unknown, and it is unclear how malleable this priming effect is with respect to a brief exposure to novel action-target contingencies. In a spatial-cueing paradigm, we presented a series of training trials prior to a series of test trials. These training sequences significantly modulated infants' attention. This suggests that action perception, when assessed through shifts of attention, is not solely based on the infants' grasping experience but quickly adapts to context-specific observed regularities.
