Titre : Eye-Tracking Reveals Absent Repetition Learning Across the Autism Spectrum: Evidence From a Passive Viewing Task Type de document : Texte imprimé et/ou numérique Auteurs : Sebastian B GAIGG, Auteur ; Marie K. KRUG, Auteur ; Marjorie SOLOMON, Auteur ; Amanda ROESTORF, Auteur ; Claire DERWENT, Auteur ; Sophie ANNS, Auteur ; Dermot M. BOWLER, Auteur ; Susan RIVERA, Auteur ; Christine W. NORDAHL, Auteur ; Emily J. H. JONES, Auteur Article en page(s) : p.1929-1946 Langues : Anglais (eng) Mots-clés : eye movement language impairment learning learning disabilities memory Index. décimale : PER Périodiques Résumé : In the domain of memory, autism is characterized by difficulties in explicitly remembering the specific order of stimuli, whereas implicit serial order memory appears to be preserved. This pattern is of considerable interest because serial order memory is known to play a critical role in children's language development. Currently, however, few paradigms exist that can effectively probe serial order memory across heterogeneous groups of children, including those who are minimally verbal. We present two experiments, involving 39 adults (20 ASD; 19 TD) and 130 children (86 ASD; 44 TD), that address this issue using an eye-tracking paradigm, which simply required participants to "watch out for a bunny" that appeared in repeating sequences of screen locations. The adults in Experiment 1 all had normative IQs, whereas Experiment 2 included children with and without substantial language and intellectual difficulties. In both experiments gaze latencies and anticipatory fixations to the bunny indicated reliable repetition learning effects in the TD but not the ASD groups. Importantly, we were able to acquire reliable data from around half of the children with significant language impairments in Experiment 2, indicating that the paradigm can shed light on important learning processes in this underrepresented group. We discuss the implications of these findings for theories of memory in ASD as well as for the utility of eye-tracking technology to probe repetition learning effects in autism. Autism Res 2020, 13: 1929-1946. © 2020 The Authors. Autism Research published by International Society for Autism Research and Wiley Periodicals LLC. LAY SUMMARY: Remembering the specific order of stimuli plays an important role in language development and is thought to be a source of difficulty for autistic individuals. Research in this area, however, rarely includes autistic participants who are minimally verbal. Here we develop an eye-tracking paradigm that demonstrates serial order learning difficulties across the autism spectrum. We discuss the implications of these findings for our understanding of the role of memory difficulties in the varied language profiles across the autism spectrum.

Titre : Not So Automatic Imitation: Expectation of Incongruence Reduces Interference in Both Autism Spectrum Disorder and Typical Development Type de document : Texte imprimé et/ou numérique Auteurs : Andrew GORDON, Auteur ; Raphael GEDDERT, Auteur ; Jeremy HOGEVEEN, Auteur ; Marie K. KRUG, Auteur ; Sukhvinder OBHI, Auteur ; Marjorie SOLOMON, Auteur Article en page(s) : p.1310-1323 Langues : Anglais (eng) Mots-clés : Automatic imitation Cognitive control Imitation Proactive control Index. décimale : PER Périodiques Résumé : Research has observed evidence for both hypo-(supposedly due to a broken mirror neuron system) and hyper-(thought to be the result of deficits in adaptive control) imitation in autism spectrum disorder (ASD). This work sought to adjudicate between these findings using an automatic imitation (AI) paradigm with the novel manipulation of the need to engage adaptive control of imitation. Results demonstrated that ASD participants do not display a specific deficit in AI capability, are able to engage in proactive control of AI, and that relative to a well-matched effector condition, AI is not selectively associated with ASD symptom severity. These data cast doubt upon the notion of impairments in imitation or its control in ASD.

Titre : Using the NIH Toolbox to Assess Cognition in Adolescents and Young Adults with Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Marjorie SOLOMON, Auteur ; Andrew GORDON, Auteur ; Ana-Maria IOSIF, Auteur ; Raphael GEDDERT, Auteur ; Marie K.

MUNDY, Auteur ; David HESSL, Auteur Article en page(s) : p.500-511 Langues : Anglais (eng) Mots-clés : NIH Toolbox adolescents adults cognitive control executive control executive functions latent profile analysis phenotypes subtypes of ASD young adults Index. décimale : PER Périodiques Résumé : Despite the clinically significant impact of executive dysfunction on the outcomes of adolescents and young adults with autism spectrum disorders (ASD), we lack a clear understanding of its prevalence, profile, and development. To address this gap, we administered the NIH Toolbox Cognition Battery to a cross-sectional Intelligence Quotient (IQ) case-matched cohort with ASD (n = 66) and typical development (TD; n = 66) ages 12-22. We used a general linear model framework to examine group differences in task performance and their associations with age. Latent profile analysis (LPA) was used to identify subgroups of individuals with similar cognitive profiles. Compared to IQ case-matched controls, ASD demonstrated poorer performance on inhibitory control (P?0.001), cognitive flexibility (P?0.001), episodic memory (P?0.02), and processing speed (P?0.001) (components of Fluid Cognition), but not on vocabulary or word reading (components of Crystallized Cognition). There was a significant positive association between age and Crystallized and Fluid Cognition in both groups. For Fluid (but not Crystallized) Cognition, ASD performed more poorly than TD at all ages. A four-group LPA model based on subtest scores best fit the data. Eighty percent of ASD belonged to two groups that exhibited relatively stronger Crystallized versus Fluid Cognition. Attention deficits were not associated with Toolbox subtest scores, but were lowest in the group with the lowest proportion of autistic participants. Adaptive functioning was poorer in the groups with the greatest proportion of autistic participants. Autistic persons are especially impaired on Fluid Cognition, and this more flexible form of thinking remains poorer in the ASD group through adolescence. LAY SUMMARY: A set of brief tests of cognitive functioning called the NIH Toolbox Cognition Battery was administered to adolescents and young adults with autism spectrum disorders (ASD; n =?66) and typical development (TD; n =?66) ages 12-22?years. Compared to TD, ASD showed poorer performance in inhibiting responses, acting flexibly, memorizing events, and processing information quickly (Fluid Cognition). Groups did not differ on vocabulary or word reading (Crystallized Cognition). Crystallized and Fluid Cognition increased with age in both groups, but the ASD group showed lower Fluid, but not Crystallized, Cognition than TD at all ages. A categorization analysis including all participants showed that most participants with ASD fell into one of two categories: a group characterized by poor performance across all tasks, or a group characterized by relatively stronger Crystallized compared to Fluid Cognition. Adaptive functioning was poorer for participants in these groups, which consisted of mostly individuals with ASD, while ADHD symptoms were lowest in the group with the greatest proportion of TD participants.

KRUG, Auteur Article en page(s) : p.3567-3580 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We used parent report data to investigate video game playing, aggression, and social impairment in adolescents with autism spectrum disorder. Parents of autistic adolescents were more likely to report that their child plays video games as a hobby compared to parents of adolescents with typical development and also reported that their children spent more time playing video games. For autistic participants, we found no differences in aggression levels or social impairment when comparing players versus non-players. However, playing video games "more than average," as compared to "average" was associated with greater aggression and greater social impairment on "awareness" and "mannerisms" subscales. Future studies should focus on how type of video game(s) played is associated with these clinically important variables.
