- 遗传学 是一个遗传学.
背景情况:
- 在自闭症患者中,运动困难很普遍,经常与其他发育挑战并发.
- 自闭症中运动障碍的生物学基础尚未完全理解.
- 罕见的基因突变与一些自闭症患者的运动技能缺陷有关,可能会影响神经刺激-抑制平衡.
研究的目的:
- 在自闭症人口中识别不同的运动亚型.
- 为了研究这些子类型之间的电机噪声差异.
- 探索与自闭症运动差异相关的潜在生物机制.
主要方法:
- 对自闭症,典型发育和发育协调障碍儿童 (3-16岁) 的公共和内部数据集的结合.
- 利用儿童运动评估电池第二版通过基于稳定性的聚类来识别自闭症运动亚型.
- 通过测量动力学不相似性来评估发动机噪声. 在达到-放下任务期间.
主要成果:
- 确定了两种可概括的自闭症运动亚型:"高"运动能力 (n=87) 和"低"运动能力 (n=69).
- 与"高"亚型相比",低"运动亚型表现出较低的智力能力和延迟的行走,但与"高"亚型相比,语言和自闭症特征相似.
- 与"高"亚型和典型发育的儿童相比,在"低"亚型的运动噪声中观察到显著更高的运动噪声,特别是在进食前的接触过程中.
结论:
- 自闭症可以分为至少两种运动子类型,其特点是不同程度的运动噪声.
- 这些运动子类型表明有明显的潜在生物机制,有助于自闭症运动差异.
- 为了验证这些发现,需要对更大的样本和各种运动任务进行进一步的研究.

Autism Spectrum Disorder
77
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
59
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.
