Accurate assessment of emotion requires the coordination of information from different sources such as faces, bodies, and voices. Adults readily integrate facial and bodily emotions. However, not much is known about the developmental origin of this capacity. Using a familiarization paired-comparison procedure, 6.5-month-olds in the current experiments were familiarized to happy, angry, or sad emotions in faces or bodies and tested with the opposite image type portraying the familiar emotion paired with a novel emotion. Infants looked longer at the familiar emotion across faces and bodies (except when familiarized to angry images and tested on the happy/angry contrast). This matching occurred not only for emotions from different affective categories (happy, angry) but also within the negative affective category (angry, sad). Thus, 6.5-month-olds, like adults, integrate emotions from bodies and faces in a fairly sophisticated manner, suggesting rapid development of emotion processing early in life.
准确评估情绪需要协调来自不同来源的信息，如面部、身体和声音。成年人能够轻松整合面部和身体所传达的情绪。然而，对于这种能力的发展起源，我们所知甚少。在当前实验中，通过使用一种熟悉化配对比较程序，让6.5个月大的婴儿熟悉面部或身体所呈现的开心、愤怒或悲伤情绪，然后用描绘熟悉情绪的相反图像类型与一种新情绪配对进行测试。婴儿对面部和身体上的熟悉情绪注视时间更长（当熟悉愤怒图像并测试开心/愤怒对比时除外）。这种匹配不仅发生在不同情感类别（开心、愤怒）的情绪之间，也发生在负面情感类别（愤怒、悲伤）之内。因此，6.5个月大的婴儿和成年人一样，能够以相当复杂的方式整合来自身体和面部的情绪，这表明情绪处理能力在生命早期发展迅速。
