概括
患有自闭症谱系障碍 (ASD) 的人在语音感知中使用上下文,与典型发达个体类似. 然而,自闭症的时间处理差异会影响语音分类,这表明非典型的语音感知不仅仅是由于上下文使用.
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
- 语音和听力科学 语言和听力科学
背景情况:
- 自闭症谱系障碍 (ASD) 理论提出了非典型的环境利用.
- 这些异常现象对语音感知的影响尚不清楚.
研究的目的:
- 研究如何词汇,光谱和时间上下文信息影响与典型发达 (TD) 个体相比,ASD个体的语音分类.
- 确定语境利用中的差异是否解释了ASD观察到的语音感知异常.
主要方法:
- 为了评估语音分类,进行了三项实验.
- 参与者包括有ASD和TD控制的个体.
- 分析了语音解歧义上的上下文影响 (词汇,光谱,时间).
主要成果:
- 患有自闭症的个体利用词汇,光谱和时间上下文来明确语音声音,类似于TD个体.
- 在有自闭症的个体中观察到一个较浅的识别曲线,当需要时间处理以进行语音分类时.
- 在患有自闭症的个体中,人们注意到语音感知敏感度降低.
结论:
- 在ASD中不典型的语音感知不仅仅是通过有限的上下文利用来解释的.
- 时间处理缺陷可能会导致ASD的语音感知异常.
- 这些发现挑战了这样一种观点,即语境使用是ASD语音感知差异的主要驱动因素.

Autism Spectrum Disorder
121
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy
114
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Learning Disabilities
163
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.

Language and Cognition
367
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.

Sensory Modalities
1.4K
Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
