We studied individual differences in 3-month-olds' perceptions of smiling and the experiential correlates of those differences. In the laboratory, infants saw a graduated series of smiles that grew in intensity of expression. As a group, 3-month-olds preferred increasingly intense expressions of smiling, but individually they showed different growth rates of preference across the smiling series. Further, infants' preferences related to their home experiences: Infants who showed greater sensitivity to smiling had mothers who more frequently encouraged attention to themselves when they were smiling and their infants were looking at them. Infant discrimination within and between categories of facial expression and the relative strengths of association between different kinds of naturally occurring experiences and infant perceptual sensitivity are discussed.
我们研究了3个月大婴儿对微笑感知的个体差异以及这些差异的体验相关因素。在实验室中，婴儿观看了一系列表情强度逐渐增加的微笑。总体而言，3个月大的婴儿更喜欢表情强度不断增加的微笑，但个体上他们在整个微笑系列中表现出不同的偏好增长率。此外，婴儿的偏好与他们在家中的经历有关：对微笑表现出更高敏感度的婴儿，其母亲在自己微笑且婴儿看着她们时，更频繁地鼓励婴儿关注自己。本文还讨论了婴儿在面部表情类别内部和之间的辨别能力，以及不同类型自然发生的经历与婴儿感知敏感度之间关联的相对强度。
