神经科学是一个神经科学.
发展心理学发展心理学
语音科学语言科学

背景情况:

早期的语言学习依赖于大脑处理语音的能力.
生命的前六个月对于听觉发育和语音特征的神经编码至关重要.

研究的目的:

在生命的前六个月内调查语音特征 (基本频率和F1形式) 的神经编码中的成熟变化.
用频率跟踪响应 (FFR) 来衡量这些语音属性的神经编码.

主要方法:

通过脑电图记录,从80名健康婴儿中获取FFR.
婴儿在出生,1个月和6个月时被记录下来,一些婴儿参加了多次录音会议.

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...
