Societal expectations for social-emotional behavior differ across sexes; however, diagnostic definitions of autism do not account for this when delineating "typical" versus "atypical." This study examines sex differences in autism in one behavior associated with strong gender biases: smiling. Computer vision was used to…

Autistic youth often experience challenges in interactions with neurotypical peers. One factor that may influence successful interactions with peers is interpersonal synchrony, or the degree to which interacting individuals align their behaviors (e.g. facial expressions) over time. Autistic and neurotypical youth were paired together into three…

Unstructured activity periods are central components of early childhood education programs. Deficits in social communication and social interaction presented by children with autism spectrum disorder (ASD) become apparent in these settings during unstructured activities, such as outdoor recess. Thirty-two preschool-age children with and without…

Differences in social communication and interaction styles between autistic and typically developing have been studied in isolation and not in the context of real-world social interaction. The current study addresses this "blind spot" by examining whether real-world social interaction quality for autistic adults differs when interacting…

Deficient social communication and interaction behaviors are a hallmark feature of individuals with autism spectrum disorder. These social communication and interaction deficits potentially stem from problems with explicit social cognition (i.e. processes that are controlled and largely conscious) as well as with implicit social cognition (i.e.…

Peer interaction can be challenging in autism spectrum disorder, but naturalistic peer-observation scales for preschoolers are scarce. This study examined psychometric qualities of the newly developed Autism Peer Interaction Observation Scale. We tested the Autism Peer Interaction Observation Scale to (a) characterize peer interactions of…

Purpose: This study examines the relationship between parental interaction style (responsive vs directive) and child-initiated joint engagement within caregiver-child interactions with toddlers diagnosed with autism spectrum disorders. Method: Videotaped interactions of 85 toddler-caregiver dyads were coded for child engagement and both parental…

Case study research methodology was used to describe the play behaviors of three infants at 12 months of age, who were later diagnosed with an autism spectrum disorder. Data included standardized test scores, and analyses of video footage of semi-structured play sessions from infants identified as high risk for autism, because of having a sibling…
