Purpose: The present study explored the extent to which early prelinguistic communication skills predict expressive language in toddlers with autistic siblings (Sibs-autism), who are known to be at high likelihood for autism and language disorder, and a comparison group of toddlers with non-autistic older siblings (Sibs-NA). Method: Participants…

Purpose: We investigate the extent to which automated audiovisual metrics extracted during an affect production task show statistically significant differences between a cohort of children diagnosed with autism spectrum disorder (ASD) and typically developing controls. Method: Forty children with ASD and 21 neurotypical controls interacted with a…

Purpose: Gesture delay in autistic infants and toddlers has been widely reported. The developmental trajectory of gesture production during early childhood is understudied. Thus, little is known about the possible changes of gesture production over time. The present study aimed to document the development of gesture production in autistic children…

Purpose: This study examined how subgroups of children with autism spectrum disorder (ASD) and developmental language disorder (DLD) perform on theory of mind (ToM) tasks and comprehend mental terms. Method: Eighty Hebrew-speaking children aged 5-6 years were divided into four groups: children with DLD, ASD and language impairment (ASD-LI), and…

Purpose: The current study examined the predictive role of gestures and gesture-speech combinations on later spoken language outcomes in minimally verbal (MV) autistic children enrolled in a blended naturalistic developmental/behavioral intervention (Joint Attention, Symbolic Play, Engagement, and Regulation [JASPER] + Enhanced Milieu Teaching…

Purpose: Intentional communication acts, or purposefully directed vocalizations and gestures, are particularly difficult for infants at elevated likelihood for eventual diagnosis of autism. The ability to measure and track intentional communication in infancy thus has the potential to aid early identification and intervention efforts. This study…

Purpose: Toddlers with Down syndrome (DS) showcase comparable or higher rates of gestures than chronological age-- and language-matched toddlers without DS. Little is known about how gesture use in toddlers with DS relates to multiple domains of development, including motor, pragmatics, language, and visual reception (VR) skills. Unexplored is…

Purpose: Thirty percent of children diagnosed with autism spectrum disorder (ASD) do not develop spoken language. To provide a means of communication for this subset of the population, augmentative and alternative communication (AAC) systems are often utilized. Low-tech options have traditionally been delivered through the in-person modality.…

Purpose: Children with autism are found to have delayed and heterogeneous gesture abilities. It is important to understand the growth of gesture abilities and the underlying factors affecting its growth. Addressing these issues can help to design effective intervention programs. Method: Thirty-five Chinese-speaking preschoolers with autism…

Purpose: Our study addresses three main questions: (a) Do autistics and neurotypicals produce different patterns of disfluencies, depending on the experimenter's direct versus averted gaze? (b) Are these patterns correlated to gender, skin conductance responses, fixations on the experimenter's face, alexithymia, or social anxiety scores? Lastly,…

Purpose: Videogaming offers an interactive, enjoyable, and socially valid context for interaction between autistic and non-autistic students in schools. In this tutorial, I describe an approach that supports communication and peer interaction through group-based videogaming. This approach creates an opportunity for autistic and non-autistic…
