项目摘要

Rapid developments in the ability to perceive and understand others' emotions are made during infancy. Within a few short months, infants move from an initial, limited ability to detect individual components that make up an expression to discriminating and categorizing emotional expressions that belong together. Development of an awareness and understanding of what people think, feel, and do is critical to children's effective functioning in their social worlds. The proposed research will examine infants' developing proficiencies in the perception of other persons' emotional expressions. One set of experiments will ask whether infants discriminate emotional expressions at a young age (3-4 months) when these expressions are portrayed in familiar contexts and by familiar persons. Several experiments will rely on an intermodal matching procedure to determine whether infants recognize a variety of emotional expressions portrayed by either their fathers or mothers or strangers. Infants will also be tested for their ability to detect invariant information across parental expressions of emotion. A second set of studies will investigate the role of acoustic and visual information in older infants (7 months) discrimination of emotional expressions. Infants will be habituated to happy and sad facial/vocal expressions and tested for their discrimination of the auditory and visual components of these expressions.

感知和理解他人的能力的快速发展情绪是在婴儿期产生的。在短短几个月内，婴儿从最初有限的检测单个组件的能力转变为将表情提升到区分和分类情感表情，这些表情属于彼此。培养人们对什么的认识和理解思考、感觉和行动对于儿童的有效运作至关重要。社交世界。这项拟议的研究将检查婴儿的发育情况。精通对他人情绪表达的感知。一一组实验将询问婴儿是否会歧视情绪表达在很小的时候(3-4个月)，当这些表情被描绘成熟悉的背景和熟悉的人。有几个实验将依赖于确定婴儿是否识别一种变体的多模式匹配程序由他们的父亲或母亲描绘的情感表达陌生人。婴儿也将接受检测不变项的能力测试通过父母的情感表达来传递信息。第二组研究将研究听觉和视觉信息在较大婴儿中的作用 (7个月)情绪表达歧视。婴儿将被习惯化快乐和悲伤的面部/声音表情，并测试它们的辨别能力这些表情的听觉和视觉成分。
