166
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.

01:30Socioemotional Development during Infancy

Socio-emotional development in infancy is primarily shaped by early emotional responses and social connections, with temperament playing a central role. Temperament refers to the consistent patterns in an individual's emotional and behavioral responses, observable even in infancy. By examining temperament, researchers can better understand an infant's unique ways of interacting with the world, influencing subsequent personality and socio-emotional growth.

677
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.
