概括
研究人员使用脑活动 (EEG) 确定了三个婴儿子组,这些子组可以预测语言的发展,但不能预测自闭症的诊断. 这种神经亚型化方法有助于理解自闭症异质性.
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
- 遗传学 是一个遗传学.
背景情况:
- 自闭症谱系障碍 (ASD) 在病因和症状方面呈现出显著的异质性.
- 鉴定ASD早期生物标志物是具有挑战性的,因为复杂的遗传和环境相互作用.
- 基于大脑表型的神经亚型提供了一个解决这种异质性的策略.
研究的目的:
- 根据脑电图 (EEG) 测量,确定不同小组的婴儿.
- 调查这些神经子类型是否预测早期语言发展轨迹.
- 为了确定EEG衍生婴儿子组是否预测后来的自闭症谱系障碍诊断.
主要方法:
- 对144名婴儿 (6-7个月大) 的脑电图 (EEG) 记录进行分析.
- 应用分类方法,包括隐性配置分析和等级分类.
- 已识别的子组与早期学习的穆伦尺度的语言发展分数的相关性.
主要成果:
- 根据与语言相关的EEG测量,确定了三个不同的婴儿子组.
- 小组成员预测了表达性和接受性语言轨迹.
- 具有高语言区域连接和左半球横向化的婴儿表现出更好的语言结果.
- 听觉网络过度激活的婴儿表现出较差的语言结果.
- 来自EEG的子组没有预测以后的ASD诊断.
结论:
- 使用早期EEG测量的神经子类型测定可以揭示不同的发育轨迹.
- 这种方法有助于理解神经发育条件的异质性.
- 在生命的第一年,没有发现ASD特异性大脑表型的证据.

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 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...

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.
