概括
内在的言论,就像公开的行动一样,涉及到由大脑活动指示的运动准备. 当行动结果可预测时,这种为内在语言做准备的大脑活动会减少.
科学领域:
- 神经科学是一个神经科学.
- 认知科学 认知科学
- 心理学 心理学 心理学
背景情况:
- 自生成的动作先有缓慢的负电脑图 (EEG) 活动,与运动准备相关.
- 这种神经活动受到行动结果的可预测性的影响.
- 目前尚不清楚内言是否也涉及与运动相关的消极性,并受到结果可预测性的影响.
研究的目的:
- 调查内在言语是否先有运动准备活动.
- 确定这种准备活动是否受到审计结果的可预测性影响.
- 为了比较内在言语和被动倾听期间的大脑活动.
主要方法:
- 三个实验使用了一个暗示范式,比较了主动 (内在的言语/明显的发声) 和被动的条件.
- 脑电图 (EEG) 测量了随机负变量 (CNV),这是运动准备的标志物.
- 实验3操纵了同时呈现的可听音符的可预测性.
主要成果:
- 与被动倾听相比,当结果不可预测时,内在的语音产生引起了更负面的迟随机负变化 (LCNV).
- 这种模式适用于内在的言语和公开的发音.
- 在内言中,一个可预测的结果导致了较小的LCNV,这是被动倾听中没有看到的效果.
结论:
- 内言与运动准备活动有关.
- 这项准备活动反映了预测的行动效应,类似于公开行动.
- 结果的可预测性影响了内在语言的神经相关性.

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...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
