まとめ
成人吃音者(AWS)は、吃音のない成人(AWNS)と比較して、音韻流暢性および実行機能が低いことを示しています。語彙の貯蔵と整理能力は損なわれていないようで、音韻情報へのアクセスに特異的な課題があることを示唆しています。
科学分野:
- 言語聴覚療法
- 認知神経科学
- 心理言語学
背景:
- 吃音(AWS)は、音声流暢性に影響を与える複雑な障害です。
- 実行機能および語彙アクセスは、流暢な音声生成に不可欠です。
研究 の 目的:
- 成人吃音者(AWS)および成人非吃音者(AWNS)における語彙アクセスおよび実行機能の調査。
- AWSの吃音に寄与する特定の認知プロセスを特定すること。
主な方法:
- 参加者は音韻および意味流暢性課題を完了しました。
- パフォーマンスは、正確な応答、クラスター化、および応答カテゴリ間のスイッチングに基づいて分析されました。
主要な成果:
- AWSはAWNSと比較して、音韻流暢性においてより少ない正確な応答を生成しました。
- AWSとAWNSの間で、クラスター化に有意な差は観察されませんでした。
- AWSはAWNSよりも有意に少ないスイッチを示しました。
結論:
- AWSはAWNSと比較して、音韻ベースの語彙アクセスおよび実行機能が弱いことを示しています。
- 音韻情報へのアクセスにおける課題が吃音に寄与していることを示唆しています。
- 意味情報の語彙貯蔵および整理は、AWSでは影響を受けないようです。

Taste Buds and Receptors
5.6K
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,...

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Deglutition
7.7K
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...

Language Development
1.1K
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...

Psychosexual Stages of Personality: Oral
3.9K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

Bulimia Nervosa

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
