概括
吃的人 (PWS) 与对照人不同,表现出稳定的非语言表现与延迟的听觉反 (DAF). 此外,PWS对检测听力延迟的敏感性也降低了,这表明有独特的感觉运动集成差异.
科学领域:
- 神经科学是一个神经科学.
- 语音语言病理学 语言病理学
- 人类的感觉运动控制
背景情况:
- 在口吃者 (PWS) 和控制者之间存在感官运动集成差异.
- 延迟的听觉反 (DAF) 扰乱了动作感知时间,影响了口头和非口头任务.
- DAF可以提高PWS患者的言语流性,但其非语言效果尚不清楚.
研究的目的:
- 与对照组相比,研究DAF对PWS中非语言感官运动同步的影响.
- 探索PWS对语音和非语言任务中的听觉延迟的敏感性.
主要方法:
- 11个PWS和13个控制器在DAF和没有DAF的情况下执行了点击和同步任务.
- 任务包括同步-延续和延迟歧视.
- 评估了参与者检测听觉延迟的能力.
主要成果:
- 根据延迟持续时间,DAF影响了控制器的性能,但PWS性能保持稳定.
- 在没有听觉反的情况下,没有观察到群体差异.
- PWS在检测语音和点击延迟方面表现出降低的灵敏度.
结论:
- 与控制器相比,当动作感知循环因延迟而被破坏时,PWS表现出明显的非语言感知运动性能.
- 这些发现有助于理解自语中的感觉运动集成模型.
- 非语言处理中的微妙差异可能是口吃的基础.

00:49The Tongue and Taste Buds
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.
01:20Taste Buds and Receptors
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...
01:25Deglutition
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...
