Atypicalities of Gesture Form and Function in Autistic Adults / Ashley B. DE MARCHENA in Journal of Autism and Developmental Disorders, 49-4 (April 2019)

Twenty-one verbally fluent autistic adults and 21 typically developing controls engaged in a controlled conversational task. Group differences were observed in both semantic/pragmatic and motoric features of spontaneously produced co-speech gestures. Autistic adults prioritized different functions of co-speech gesture. Specifically, they used gesture more than controls to facilitate conversational turn-taking, demonstrating a novel nonverbal strategy for regulating conversational dynamics. Autistic adults were more likely to gesture unilaterally than bilaterally, a motoric feature of gesture that was individually associated with autism symptoms. Co-speech gestures may provide a link between nonverbal communication symptoms and known differences in motor performance in autism.

Parent-Endorsed Sex Differences in Toddlers with and Without ASD: Utilizing the M-CHAT / Roald A. ØIEN in Journal of Autism and Developmental Disorders, 47-1 (January 2017)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 47-1 (January 2017) . - p.126-134 Titre : Parent-Endorsed Sex Differences in Toddlers with and Without ASD: Utilizing the M-CHAT Type de document : texte imprimé Auteurs : Roald A.

Baron-Cohen (Trends Cogn Sci 6(6):248–254, 2002) suggested ASD could be considered an extreme expression of normal male, compared to female, phenotypic profiles. In this paper, sex-specific M-CHAT scores from N = 53,728 18-month-old toddlers, including n = 185 (32 females) with ASD, were examined. Results suggest a nuanced view of the “extreme male brain theory of autism”. At an item level, almost every male versus female disadvantage in the broader population was consistent with M-CHAT vulnerabilities in ASD. However, controlling for total M-CHAT failures, this male disadvantage was more equivocal and many classically ASD-associated features were found more common in non-ASD. Within ASD, females showed relative strengths in joint attention, but impairments in imitation.

Social Robots as Embedded Reinforcers of Social Behavior in Children with Autism / Elizabeth S. KIM in Journal of Autism and Developmental Disorders, 43-5 (May 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-5 (May 2013) . - p.1038-1049 Titre : Social Robots as Embedded Reinforcers of Social Behavior in Children with Autism Type de document : texte imprimé Auteurs : Elizabeth S.

Children spoke more in general, and directed more speech to the adult confederate, when the interaction partner was a robot, as compared to a human or computer game interaction partner. Children spoke as much to the robot as to the adult interaction partner. This study provides the largest demonstration of social human-robot interaction in children with autism to date. Our findings suggest that social robots may be developed into useful tools for social skills and communication therapies, specifically by embedding social interaction into intrinsic reinforcers and motivators.

The relationship between autism symptoms and arousal level in toddlers with autism spectrum disorder, as measured by electrodermal activity / Emily Barbara PRINCE in Autism, 21-4 (May 2017)

Toddlers with autism spectrum disorder were found to have greater increases in skin conductance level than their typical peers in response to administered play activities. In the autism spectrum disorder group, a positive relationship was observed between restrictive and repetitive behaviors and skin conductance level increases in response to mechanical toys, whereas the opposite pattern was observed for passive toys. This preliminary study is the first to examine electrodermal activity levels in toddlers with autism spectrum disorder during play-based, naturalistic settings, and it highlights the potential for electrodermal activity as a measure of individual variability within autism spectrum disorder and early development.
