OBJECTIVE
Previous infant studies investigated neural mirroring during the observation of live or video actions. However, both methods have their (dis)advantages and studies using one of these methods are not always directly comparable. Therefore, the present study directly compared neural mirroring activity in a video setting with a live setting in infants between 18 and 36 months old.
METHODS
Central mu rhythm suppression was measured through EEG recordings during the observation and imitation of the same goal-directed and mimicked actions presented either on video or live.
RESULTS
Results revealed significant mu suppression during action imitation in both settings but stronger mu suppression was observed in the live setting during this condition. Significant mu suppression during the observation of goal-directed actions and mimicked actions was only observed in the live setting.
CONCLUSION
This study revealed a different influence of video and live actions on neural mirroring activity in infants.
SIGNIFICANCE
It is recommended to use live actions to investigate neural mirroring in young children.
目的
先前的婴儿研究调查了在观察现场或视频动作时的神经镜像。然而，这两种方法都有其（优）缺点，并且使用这些方法中的一种的研究并不总是可以直接进行比较的。因此，本研究在 18 至 36 个月大的婴儿中，直接比较了视频设置和现场设置中对相同目标导向和模仿动作的观察和模仿过程中的神经镜像活动。
方法
通过 EEG 记录在观察和模仿相同目标导向和模仿动作时测量中央 mu 节律抑制，这些动作分别通过视频或现场呈现。
结果
结果表明，在两种设置中，在动作模仿过程中都观察到显著的 mu 抑制，但在这种情况下，现场设置中观察到更强的 mu 抑制。仅在现场设置中观察到在观察目标导向动作和模仿动作时的 mu 抑制。
结论
本研究揭示了视频和现场动作对婴儿神经镜像活动的不同影响。
意义
建议使用现场动作来研究幼儿的神经镜像。
