There are multiple forms of knowledge about people. Whether diverse person-related data interact is of interest regarding the more general issue of integration of multi-source information about the world. Our goal was to examine whether perception of a person's face or voice enhanced the encoding of their biographic data. We performed three experiments. In the first experiment, subjects learned the biographic data of a character with or without a video clip of their face. In the second experiment, they learned the character's data with an audio clip of either a generic narrator's voice or the character's voice relating the same biographic information. In the third experiment, an audiovisual clip of both the face and voice of either a generic narrator or the character accompanied the learning of biographic data. After learning, a test phase presented biographic data alone, and subjects were tested first for familiarity and second for matching of biographic data to the name. The results showed equivalent learning of biographic data across all three experiments, and none showed evidence that a character's face or voice enhanced the learning of biographic information. We conclude that the simultaneous processing of perceptual representations of people may not modulate the encoding of biographic data.
关于人的知识有多种形式。就关于世界的多源信息整合这一更普遍的问题而言，不同的与人相关的数据是否相互作用是一个有趣的问题。我们的目标是研究对一个人的面部或声音的感知是否会增强对其传记数据的编码。我们进行了三项实验。在第一个实验中，受试者在有或没有其面部视频片段的情况下学习一个角色的传记数据。在第二个实验中，他们通过一段普通叙述者的声音或该角色讲述相同传记信息的音频片段来学习该角色的数据。在第三个实验中，一段普通叙述者或该角色的面部和声音的视听片段伴随着传记数据的学习。学习后，测试阶段单独呈现传记数据，首先测试受试者的熟悉程度，其次测试传记数据与名字的匹配情况。结果显示，在所有三项实验中，传记数据的学习效果相当，且没有一项实验表明角色的面部或声音能增强对传记信息的学习。我们得出结论，对人的感知表征的同时处理可能不会调节传记数据的编码。
