概括

婴儿学习语言更多地依赖于声音模式 (prosody),而不是统计线索来识别单词. 当声音模式被删除时,婴儿无法分割单词,突出了prosody在语音分割中的早期重要性.

科学领域:

发展心理学发展心理学
语言学的语言学.
认知科学认知科学

背景情况:

婴儿通过使用prosodic和统计线索细分流利的语言.
顺序的线索包括压力模式,而统计线索涉及过渡概率 (TP).
了解早期语音细分机制对于语言学习至关重要.

研究的目的:

为了研究6个月大的学习德语的婴儿使用prosodic与语音细分的统计线索.
为了确定prosodic和过渡概率线索在早期单词细分中的相对重要性.
检查语言特异性对婴儿语音细分的影响.

主要方法:

在三个实验中,让6个月大的婴儿熟悉人工语言的字符串.
实验1:TP标志着单词边界或不利于横压力模式.
实验3:TP标志着字的边界,没有prosodic线索;所有的实验使用相同的测试条件.

主要成果:

与TP相比,婴儿在单词细分方面更依赖prosodic线索.
当prosodic线索缺席时,没有观察到单词分割的证据.
婴儿的细分能力受到前体信息的存在的显著影响.

结论:

在德语学习婴儿的早期语音细分中,prosodic线索比过渡概率发挥更为关键的作用.
缺少口音阻碍了婴儿细分词语的能力,即使有统计信息.
语言特有的结构性质,如prosody,显著影响早期细分机制.

Language Development

Language 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...

Language and Cognition

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
