One of the most salient social categories conveyed by human faces and voices is gender. We investigated the developmental emergence of the ability to perceive the coherence of auditory and visual attributes of gender in 6- and 9-month-old infants. Infants viewed two side-by-side video clips of a man and a woman singing a nursery rhyme and heard a synchronous male or female soundtrack. Results showed that 6-month-old infants did not match the audible and visible attributes of gender, and 9-month-old infants matched only female faces and voices. These findings indicate that the ability to perceive the multisensory coherence of gender emerges relatively late in infancy and that it reflects the greater experience that most infants have with female faces and voices.
人类面部和声音所传达的最显著的社会类别之一是性别。我们研究了6个月和9个月大婴儿感知性别听觉和视觉属性连贯性能力的发展情况。婴儿观看了一名男性和一名女性并排演唱童谣的两个视频片段,并听到同步的男性或女性声音。结果显示,6个月大的婴儿没有将性别的可听属性和可见属性进行匹配,而9个月大的婴儿仅将女性的面孔和声音进行了匹配。这些发现表明,感知性别的多感官连贯性的能力在婴儿期出现得相对较晚,并且这反映了大多数婴儿对女性面孔和声音有更多的体验。
