概括

自闭症患者表现出更杂的内部节律时间,影响感觉运动协调. 这项研究发现自闭症患者有节奏时间困难,而不仅仅是运动控制问题.

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
自闭症研究自闭症研究

背景情况:

自闭症患者经常在时间协调任务中扎,比如与计量仪同步.
目前尚不清楚这些挑战是否源于运动缺陷或感知时间问题.

研究的目的:

调查自闭症患者的感觉运动协调困难是否由于运动差异或感知节奏时间缺陷.
分析自闭症和非自闭症个体的同步,延续和时间感知.

主要方法:

招募自闭症和非自闭症参与者进行在线研究.
评估了手指敲击的同步和延续,以及节奏时间感知 (非同步检测).
分析了用于纠错,电机噪声和内部计时器噪声的同步数据.

主要成果:

没有发现有意义的证据表明同步任务的错误纠正减少.
有令人信服的证据表明,在同步,延续和感知任务中,内部节奏计时的噪音更大.
在自闭症参与者中观察到内部计时的噪音.

结论:

更杂的内部节律定时过程有助于自闭症的感觉运动协调挑战.
研究结果表明,节奏时间,而不仅仅是运动控制,是自闭症相关协调困难的关键因素.

Autism Spectrum Disorder

Autism Spectrum Disorder

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.
