最近的报告类似模式的脑电活动（脑电图：EEG）在行动执行和观察记录从头皮位置在运动相关的区域在婴儿和成人提出了两个基本能力的可能性，控制自己的有意行动和感知他人的行动可能是完整的个体发育过程中相关。然而，据我们所知，没有关于运动技能发展之间关系的公开报道（即，记录实际的运动技能表现）和动作执行和动作观察期间的EEG。在本研究中，我们收集了21个9个月大的孩子谁得到了机会，达到玩具，谁也观察到实验者达到玩具的脑电图。在到达事件期间，从EEG计算事件相关去极化（ERD）。我们评估了婴儿的伸手抓握能力，包括达到潜伏期，错误，手的预成形，双手达到，并发现在动作观察过程中，在运动相关区域的头皮电极中记录的desperization与执行过程中的动作能力相关。婴儿谁是更有能力的reachers相比，不太有能力的reachers，表现出更大的ERD，而观察达到抓。这些结果为早期出现的神经系统提供了初步证据，该系统将自己的行为与对他人行为的感知相结合。
Recent reports of similar patterns of brain electrical activity (Electroencephalogram: EEG) during action execution and observation recorded from scalp locations over motor-related regions in infants and adults have raised the possibility that two foundational abilities—controlling one’s own intentional actions and perceiving others’ actions—may be integrally related during ontogeny. However, to our knowledge, there are no published reports of the relations between developments in motor skill (i.e., recording actual motor skill performance) and EEG during both action execution and action observation. In the present study we collected EEG from 21 9-month-olds who were given opportunities to reach for toys and who also observed an experimenter reach for toys. Event-related desynchronization (ERD) was computed from the EEG during the reaching events. We assessed infants’ reaching-grasping competence, including reach latency, errors, preshaping of the hand, and bimanual reaches, and found that desynchronization recorded in scalp electrodes over motor-related regions during action observation was associated with action competence during execution. Infants who were more competent reachers, compared to less competent reachers, exhibited greater ERD while observing reaching-grasping. These results provide initial evidence for an early emerging neural system integrating one’s own actions with the perception of others’ actions.
