Titre : Does Gender Influence Core Deficits in ASD? An Investigation into Social-Communication and Play of Girls and Boys with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Clare HARROP, Auteur ; Stephanie Y. SHIRE, Auteur ; Amanda GULSRUD, Auteur ; Ya-Chih CHANG, Auteur ; Eric ISHIJIMA, Auteur ; Kathy LAWTON, Auteur ; Connie KASARI, Auteur Article en page(s) : p.766-777 Langues : Anglais (eng) Mots-clés : Autism Gender Social-communication Joint attention Play Index. décimale : PER Périodiques Résumé : Due to the predominance of boys diagnosed with autism spectrum disorders (ASD), girls are rarely studied independently. Research specifically focusing on play and social-communication in girls with ASD is extremely varied. We were interested in whether girls with ASD demonstrated equivalent social-communication and play skills in early childhood relative to boys, using two measures focused on the specific quantification of these variables. We also examined whether the associations between developmental variables and social-communication and play differed by gender. Forty girls with ASD were individually matched to 40 boys based on ASD severity. Our results suggest that girls and boys were more similar than different, however they also raise questions about the potential differential associations between development and requesting ability in girls and boys with ASD.

Titre : Reduced P300 amplitude in children and adolescents with autism is associated with slowed processing speed, executive difficulties, and social-communication problems Type de document : Texte imprimé et/ou numérique Auteurs : Jonathan LASSEN, Auteur ; Bob ORANJE, Auteur ; Martin VESTERGAARD, Auteur ; Malene FOLDAGER, Auteur ; Troels W KJÆR, Auteur ; Bodil AGGERNÆS, Auteur ; Sidse ARNFRED, Auteur Article en page(s) : p.222-232 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder autism electroencephalography executive functions P300 selective attention social-communication Index. décimale : PER Périodiques Résumé : Compared to their neurotypically developing peers, children and adolescents with autism spectrum disorders tend to have attenuated neural responses in the parietal lobe when attending sensory input, as reflected by a reduced P3b amplitude measured with electroencephalography. However, it is unknown whether a reduced P3b amplitude in autistic children and adolescents is associated with their autism traits, daily functioning, and/or cognitive functions. To address these questions, we assessed 57 children with autism aged 7-14?years and 57 typically developing children with electroencephalography using a binaural auditory oddball paradigm. Participants further underwent cognitive assessment, and parents reported on autistic traits, executive functioning, and adaptive functioning. As expected, children with autism had lower P3b amplitude compared to controls. Across all participants, a lower P3b amplitude was associated with more parent-reported social-communication problems and impairments in daily executive functioning. Children with autism had reduced visual processing speed, which was coupled to a lower P3b amplitude. In conclusion, we found attenuated P3b amplitude in children with autism performing an auditory selective attention task, which generalized to impaired cross-modal processing of visual input and an underlying impairment in allocating attentional resources critical for social and executive functioning.Lay abstractSelective attention to auditory input is reflected in the brain by an electric amplitude called the P3b amplitude, which is measured using electroencephalography. Previous research has shown that children and adolescents with autism have an attenuated P3b amplitude when they have to attend specific sounds while ignoring other sounds. However, it is unknown whether a reduced P3b amplitude in autistic children and adolescents is associated with their autism features, daily functioning and/or cognitive functions. This study aimed to examine these questions. Therefore, we assessed selective attention to auditory input in 57 children with autism aged 7-14?years and 57 neurotypically developing controls while measuring their brain activity with electroencephalography. Participants further underwent cognitive assessment, and parents reported on autistic traits and daily functioning. As expected, children with autism had lower P3b amplitude compared to their neurotypical peers. Importantly, an attenuated P3b amplitude was associated with more parent-reported social-communication problems and difficulties with daily functioning. Children with autism further had reduced processing speed of visual input, which also was coupled to a lower P3b amplitude. In conclusion, we found attenuated P3b amplitude in children with autism performing an auditory selective attention task, which was related to difficulties with processing visual input and allocating attentional resources critical for social and daily functioning. The results suggest that autistic children are more vulnerable to being disturbed when the environment is filled with conflicting sensory input.

With increases in enrollment of children with autism spectrum disorder (ASD) in school systems, establishing the effectiveness and feasibility of interventions implemented in school settings is important. In clinical settings, interventions targeting social-communication and play behaviors have increased these skills and impacted later language abilities. Results of this single-case design study indicated the ASAP intervention had a positive impact on social-communication and play skills for three preschoolers with ASD. All participants showed either increases in frequency or more stability in targeted behaviors. Social validity results provide additional support for the use of ASAP with preschoolers with ASD.

DICHTER, Auteur Article en page(s) : p.715-728 Langues : Anglais (eng) Mots-clés : autism spectrum disorder fMRI reward prediction error social social-communication Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterized by impaired predictive abilities; however, the neural mechanisms subsuming reward prediction errors in ASD are poorly understood. In the current study, we investigated neural responses during social and nonsocial reward prediction errors in 22 adolescents with ASD (ages 12-17) and 20 typically developing control adolescents (ages 12-18). Participants performed a reward prediction error task using both social (i.e., faces) and nonsocial (i.e., objects) rewards during a functional magnetic resonance imaging scan. Reward prediction errors were defined in two ways: (a) the signed prediction error, the difference between the experienced and expected reward; and (b) the thresholded unsigned prediction error, the difference between expected and unexpected outcomes regardless of magnitude. During social reward prediction errors, the ASD group demonstrated the following differences relative to the TD group: (a) signed prediction error: decreased activation in the right precentral gyrus and increased activation in the right frontal pole; and (b) thresholded unsigned prediction error: increased activation in the right anterior cingulate gyrus and bilateral precentral gyrus. Groups did not differ in brain activation during nonsocial reward prediction errors. Within the ASD group, exploratory analyses revealed that reaction times and social-communication impairments were related to precentral gyrus activation during social prediction errors. These findings elucidate the neural mechanisms of social reward prediction errors in ASD and suggest that ASD is characterized by greater neural atypicalities during social, relative to nonsocial, reward prediction errors in ASD. Autism Res 2020, 13: 715-728. (c) 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We used brain imaging to evaluate differences in brain activation in adolescents with autism while they performed tasks that involved learning about social and nonsocial information. We found no differences in brain responses during the nonsocial condition, but differences during the social condition of the learning task. This study provides evidence that autism may involve different patterns of brain activation when learning about social information.

LANDA, Auteur Article en page(s) : p.1352-1365 Langues : Anglais (eng) Mots-clés : Autism Broad autism phenotype High risk siblings Joint attention Pragmatic language Social-communication Index. décimale : PER Périodiques Résumé : Little empirical evidence exists about school-age pragmatic communication or predictors in siblings at heightened familial risk for ASD (HR) and low-risk (LR) controls. The Pragmatic Rating Scale-School-Age (Landa unpublished) was scored for 49 HR siblings and 18 LR controls at 8-12 years. Social-communication and language measures were collected between 14 and 36 months. At 36-months, siblings were classified as ASD (HR-ASD, n = 15), broad autism phenotype (HR-BAP, n = 19), or typically developing (HR-TD, n = 15). Results revealed a pragmatic continuum with significantly better scores for HR-TD than HR-BAP or HR-ASD, and HR-BAP than HR-ASD. Per regression models including all participants, 14-month joint attention initiations predicted school-age pragmatic communication, as did 24-month social-communication and expressive language scores. Early joint attention, social-communication, and language abilities contribute to later pragmatic functioning.
