进行了两项研究来检验面部运动和时间对应在快乐和愤怒表达事件的联运感知中的作用。 7 个月大的婴儿看到了 2 个视频面部表情，并听到了其中一个面部表情的单一声音特征。婴儿看到的是正常照明的脸部（完全照明条件）或脸部的移动点显示（点光条件）。在研究 1 中，一名女性用声音表达了影响，另一名女性则用面部表情表达了影响，而且她们所说的内容也不同。点光源条件下的婴儿对情感一致的显示表现出可靠的偏好，而完全照明条件下的婴儿则对情感一致的显示没有表现出偏好。在第二项研究中，视觉和声音展示由一个人在一次情况下产生，并以 5 秒不同步的方式呈现给婴儿。在这两种情况下，婴儿观看情感一致的展示的时间更长。这两项研究的结果表明，婴儿可以根据运动信息区分快乐和愤怒的情感表达，并且统一这些情感事件的时间对应关系可能是情感特定的节律。
2 studies were conducted to examine the roles of facial motion and temporal correspondences in the intermodal perception of happy and angry expressive events. 7-month-old infants saw 2 video facial expressions and heard a single vocal expression characteristic of one of the facial expressions. Infants saw either a normally lighted face (fully illuminated condition) or a moving dot display of a face (point light condition). In Study 1, one woman expressed the affects vocally, another woman expressed the affects facially, and what they said also differed. Infants in the point light condition showed a reliable preference for the affectively concordant displays, while infants in the fully illuminated condition showed no preference for the affectively concordant display. In a second study, the visual and vocal displays were produced by a single individual on one occasion and were presented to infants 5 sec out of synchrony. Infants in both conditions looked longer at the affectively concordant displays. The results of the 2 studies indicate that infants can discriminate happy and angry affective expressions on the basis of motion information, and that the temporal correspondences unifying these affective events may be affect-specific rhythms.
