Recent findings indicate that 7-months-old infants perceive and represent the sounds inherent to moving human bodies. However, it is not known whether infants integrate auditory and visual information in representations of specific human actions. To address this issue, we used ERPs to investigate infants’ neural sensitivity to the correspondence between sounds and images of human actions. In a cross-modal priming paradigm, 7-months-olds were presented with the sounds generated by two types of human body movement, walking and handclapping, after watching the kinematics of those actions in either a congruent or incongruent manner. ERPs recorded from frontal, central and parietal electrodes in response to action sounds indicate that 7-months-old infants perceptually link the visual and auditory cues of human actions. However, at this age these percepts do not seem to be integrated in cognitive multimodal representations of human actions.

最近的发现表明，7个月大的婴儿感知并代表了移动人体固有的声音。然而，尚不清楚婴儿是否在特定人类行为的表征中整合听觉和视觉信息。为了解决这个问题，我们使用ERP来调查婴儿对声音和人体动作图像之间的对应关系的神经敏感性。在跨模式启动范例中，在以同等或不一致的方式观看了这些动作的运动学后，向7个月大的孩子展示了两种类型的人体运动（行走和拍手）产生的声音。从额，中央和顶电极记录的ERPs响应动作声音，表明7个月大的婴儿在感知上联系着人类动作的视觉和听觉暗示。然而，
