概括
内在的言语,我们心中的沉默的声音,会产生一种叫做后果性放电的脑信号. 这项研究发现,与公开演讲不同的是,尾随性放电不会编码内在演讲的音量.
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:
- 露面发言的产生涉及一个附带的排放,抑制听觉反应.
- 内在的言语也会产生相应的释放,传达时间和内容信息.
- 随随性放电在内在语音音量中的作用仍然未被探索.
研究的目的:
- 为了调查与内在言语相关的后果放电是否对其体积进行编码信息.
- 通过听觉感知来比较不同音量内在言语中的神经反应.
主要方法:
- 参与者从事通过视觉动画引发的内在语言 (大声/安静).
- 测量了听觉唤起的潜能 (ERP),特别是N1和缓慢的负波.
- 研究人员将神经反应与内在语音产生和被动倾听条件进行了比较.
主要成果:
- 与倾听相比,内在语音产生减弱了N1组件,并增强了缓慢的负波.
- 这些神经调制发生不论内在语音的体积.
- 内言的量并没有对N1或慢负波组件产生差异性影响.
结论:
- 在内在演讲过程中产生的后果性放电似乎不编码音量信息.
- 内在和公开言论的神经过程之间存在功能上的差异.
- 对听觉脱敏的护理功能可能对非可听的内在言语不那么重要.

Sound Intensity
The loudness of a sound source is related to how energetically the source is vibrating, consequently making the molecules of the propagation medium vibrate. To measure the loudness of a source, the physical quantity of interest is the intensity. This is defined as the energy emitted per unit of time per unit of area perpendicular to the sound wave's propagation direction. Since the total energy is greater if the source vibrates for a longer duration and over a larger area, dividing the emitted...
Sound Intensity Level
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and hence a...

Non-Verbal Cues
Non-verbal communication extends beyond gestures and facial expressions to include vocal elements known as paralanguage. Paralanguage consists of non-verbal vocal cues such as pitch, loudness, speech rate, pauses, and non-verbal vocalizations like laughter, sighs, and moans. These elements not only accompany speech but also provide critical emotional and contextual information.The Role of Paralanguage in CommunicationParalanguage adds depth to spoken language by conveying emotions and...
