概括
患有自闭症谱系障碍 (ASD) 的儿童可能不会像正常发育的婴儿那样专注于生物运动. 相反,他们可能会对非社会物理线索做出反应,影响社会发展.
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:
- 婴儿通常会参加生物运动,这对社会发展和捕食者检测至关重要.
- 生物运动感知与社交信号处理共享神经通路,如面部识别.
- 对生物运动的早期关注可能会先于推断他人的意图的能力.
研究的目的:

Piaget's Stage 1 of Cognitive Development
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

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.
