概括
患有自闭症谱系障碍 (ASD) 的人表现出较慢的语音产生,但不一定会影响语言预测. 较高的自闭症特征与较难预测的语言使用相关.
科学领域:
- 神经科学是一个神经科学.
- 心理学 心理学 心理学
- 语言学的语言学.
背景情况:
- 自闭症谱系障碍 (ASD) 与总域预测能力障碍有关.
- 预测事件结果的困难影响了ASD在动态环境中的导航.
- 这些预测缺陷的领域特异性,特别是在语言方面,仍未得到充分研究.
研究的目的:
- 调查ASD患者语言预测中的非典型性.
- 确定预测障碍是否延伸到ASD中的语言处理.
- 探索自闭症特征与语言预测之间的关系.
主要方法:
- 利用一个cloze概率任务来评估ASD个体的语言预测和典型的发展对照.
- 实验1涉及一个离线cloze任务,其中有33名自闭症患者和64名对照.
- 实验2包括一个基于实验室的钟声任务,包括19名ASD患者和22名对照者,测量语音发声时间.
主要成果:
- 患有自闭症和没有自闭症的个体之间的克洛兹概率没有显著差异.
- 更高水平的自闭症特征与倾向于更低概率 (非模态) 休息反应相关.
- 与对照人群相比,患有自闭症的个体表现出明显较慢的语音发声时间 (~200毫秒).
结论:
- 患有自闭症的人在语言预测方面表现出效率低下.
- 特定的自闭症特征与这些语言预测效率低下有关.
- 语音发声时间显示,语音发声速度较慢是ASD的一个显著发现.

Autism Spectrum Disorder
55
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.

Language and Cognition
314
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.

Language Development
307
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...

Modeling in Therapy
42
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
81
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.
