West, Kelsey L.; Roemer, Emily J.; Northrup, Jessie B.; Iverson, Jana M. – Journal of Speech, Language, and Hearing Research, 2020

The purpose of this study was to investigate whether different "types" of actions and gestures are more or less likely to develop…

Gangi, Devon N.; Schwichtenberg, A. J.; Iosif, Ana-Maria; Young, Gregory S.; Baguio, Fam; Ozonoff, Sally – Autism: The International Journal of Research and Practice, 2018
Infant social-communicative behavior, such as gaze to the face of an interactive partner, is an important early developmental skill. Children with autism spectrum disorder exhibit atypicalities in social-communicative behavior, including gaze and eye contact. Behavioral differences in infancy may serve as early markers of autism spectrum disorder…

C.; Zander, E.; Charman, T. – Journal of Autism and Developmental Disorders, 2018
Research on sex-related differences in Autism Spectrum Disorder (ASD) has been impeded by small samples. We pooled 28 datasets from 18 sites across nine European countries to examine sex differences in the ASD phenotype on the ADI-R (376 females, 1763 males) and ADOS (233 females, 1187 males). On the ADI-R, early childhood restricted and…

Differences in joint attention are prominent for some children with autism and are often used as an indicator of the disorder. This study examined the joint attention competencies of young children with autism who demonstrated joint attention ability and compared them to children with developmental delays. A total of 40 children with autism and…
