概括

产前语言暴露 (PLE) 可能有助于婴儿语言学习,但以前的模型缺乏现实性. 本研究引入了对PLE建模的现实框架,揭示了它对婴儿语言学习模型的影响.

科学领域:

发展心理学发展心理学
计算语言学计算语言学
听觉神经科学听觉神经科学

背景情况:

婴儿的语言学习被假设是从产前开始的.
研究表明胎儿和新生儿可以区分母语.
以前的产前语言暴露 (PLE) 的计算模型缺乏生态代表性.

研究的目的:

开发一个生态代表性的框架来建模PLE.
使用这个框架,用计算模型模拟语言学习.
为了比较PLE对婴儿语言现象的影响与仅产后输入的影响.

主要方法:

开发了一个框架,模拟产前语音输入量和质量.
结合了产前语言暴露的经验估计.
模拟语音信号减弱到胎儿的听觉系统.
使用计算模型进行无监督学习模拟.

主要成果:

纳入PLE会影响计算模型的语言学习结果.
在满期和早产婴儿模型之间观察到的差异.
根据语言任务,PLE的持续时间会影响模型的行为.

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.
