Language Development

1.0K
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...

Higher Mental Functions of the Brain: Language

4.0K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

科学领域:

  • 神经科学是一个神经科学.
  • 发展心理学 发展心理学
  • 语音语言病理学 语言病理学

背景情况:

  • 过早出生是语言延迟的已知预测因素,但对于个体儿童的评估缺乏准确性.
  • 早期干预 (EI) 对语言延迟非常有效,但需要准确,儿童级预测.
  • 目前的预测方法不足以在学龄前及时处方EI.

研究的目的:

  • 利用婴儿神经数据开发和验证语言延迟的预测模型.
  • 预测语言延迟,以实现先发制人的早期干预.
  • 利用脑电图 (EEG) 神经语音编码来早期识别有风险的儿童.

主要方法:

  • 记录了423名婴儿 (1-24个月) 的EEG神经语音编码 (语音听觉脑干反应 (ABR)).
  • 使用贝利婴幼儿发育 (7-32个月) 尺度收集语言结果.
  • 采用随机森林模型来比较带有和没有EEG测量的预测准确度.

主要成果:

  • 纳入EEG测量的模型显著超过了非神经临床预测指标.
  • 仅使用EEG的模型实现了>90%的灵敏度和AUC,在外部验证后持续>80%的灵敏度和>90%的AUC.
  • 非神经模型 (妊娠年龄,出生体重) 预测的结果超出了机会,但不如EEG模型那么准确.

结论:

  • 语音ABR显示承诺作为一种新的查工具,用于识别语言延迟风险的婴儿.
  • 通过语音ABR进行早期识别,可以及时实现EI,从而有可能增强语言的发展.
  • 与现有的方法相比,这种基于神经系统的方法为儿童水平的预测提供了更精确的方法.
