概括
在感知狭窄开始之前,婴儿对匹配的熟悉面孔和语音表现出更大的注意力. 到了9个月,这种对面部语音一致性的敏感性会减弱,因为婴儿专注于熟悉的刺激.
科学领域:
- 发展心理学 发展心理学
- 认知神经科学 认知神经科学
- 婴儿的感知婴儿的感知
背景情况:
- 感知缩小根据曝光细化婴儿对面部和语言的感知.
- 婴儿对熟悉的刺激 (例如,母语,同种族的面孔) 变得更加适应,对不熟悉的刺激变得不那么适应.
- 感知狭窄对面部和语音综合感知的影响仍然不清楚.
研究的目的:
- 为了调查婴儿在感知狭窄期间面部语音一致性的敏感性如何变化.
- 为了检查3个月和9个月大的婴儿对熟悉和不熟悉的面部语言配对的反应.
主要方法:
- 在3个月和9个月大的德国婴儿身上使用了跨式联想范式.
- 婴儿观看了德国/中国面孔的序列,并与德国/法国的口语句子配对.
- 总查看时间被分析为一致 (熟悉-熟悉,不熟悉-不熟悉) 与不一致 (熟悉-不熟悉,不熟悉-熟悉) 的条件.
主要成果:
- 3个月大的孩子在与不一致的相比,在一致的面部语音配对上看起来更长.
- 9个月大的孩子表现出相似的寻找时间,无论是对应的还是不对应的条件.
- 这表明在感知缩小开始之前,人们对面部语言匹配和不匹配的注意力增加了.
结论:
- 在典型的感知狭窄开始之前,婴儿对面部语言一致性的注意力更大.
- 感知狭窄的发育变化会影响婴儿如何处理多模式的社会信息.
- 早期对面部语音配对的注意力可能反映出在专业化发生之前更广泛的初始敏感性.

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

01:21The Nativist Approach
34
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

01:22Language Development

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

01:14Piaget's Stage 1 of Cognitive Development
602
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.
