This study investigates mothers' responses to infant communication among infants at heightened genetic risk (high risk) of autism spectrum disorder compared to infants with no such risk (low risk). A total of 26 infants, 12 of whom had an older sibling with autism spectrum disorder, were observed during naturalistic in-home interaction and semistructured play with their mothers at 13 and 18 months of age. Results indicate that overall, mothers of low-risk and high-risk infants were highly and similarly responsive to their infants' communicative behaviors. However, examination of infant vocal and gestural communication development together with maternal verbal responses and translations (i.e. verbally labeling a gesture referent) suggests that delays in early communication development observed among high-risk infants may alter the input that these infants receive; this in turn may have cascading effects on the subsequent development of communication and language.

Autism Spectrum Disorder01:19

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.

Relationship with Parents: Attachment

Parent-child interactions lay the foundation for how we understand relationships throughout life. These interactions are not uniform across families; instead, they are shaped by a range of environmental, emotional, and behavioral factors unique to each caregiver-child dynamic. Social psychologists study these early relationships to understand how patterns formed in infancy influence social functioning and interpersonal behavior in adulthood.Attachment Theory and Early Relational ModelsJohn...

Socioemotional 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.
