SHIC, Auteur ; Gahan PANDINA, Auteur Article en page(s) : p.279-293 Langues : Anglais (eng) Mots-clés : Asd Automated Emotion Expression Facet Facial Index. décimale : PER Périodiques Résumé : Facial expression is impaired in autism spectrum disorder (ASD), but rarely systematically studied. We focus on the ability of individuals with ASD to produce facial expressions of emotions in response to a verbal prompt. We used the Janssen Autism Knowledge Engine (JAKE((R))), including automated facial expression analysis software (FACET) to measure facial expressions in individuals with ASD (n = 144) and a typically developing (TD) comparison group (n = 41). Differences in ability to produce facial expressions were observed between ASD and TD groups, demonstrated by activation of facial action units (happy, scared, surprised, disgusted, but not angry or sad). Activation of facial action units correlated with parent-reported social communication skills. This approach has potential for diagnostic and response to intervention measures.Trial Registration NCT02299700.

Titre : Behavioral, cognitive, and adaptive development in infants with autism spectrum disorder in the first 2 years of life Type de document : Texte imprimé et/ou numérique Auteurs : A. ESTES, Auteur ; Lonnie ZWAIGENBAUM, Auteur ; H. GU, Auteur ; T. ST JOHN, Auteur ; S. PATERSON, Auteur ; J. T. ELISON, Auteur ; Heather C. HAZLETT, Auteur ; Kelly N. BOTTERON, Auteur ; Stephen R.

PIVEN, Auteur Article en page(s) : p.24 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : BACKGROUND: To delineate the early progression of autism spectrum disorder (ASD) symptoms, this study investigated developmental characteristics of infants at high familial risk for ASD (HR), and infants at low risk (LR). METHODS: Participants included 210 HR and 98 LR infants across 4 sites with comparable behavioral data at age 6, 12, and 24 months assessed in the domains of cognitive development (Mullen Scales of Early Learning), adaptive skills (Vineland Adaptive Behavioral Scales), and early behavioral features of ASD (Autism Observation Scale for Infants). Participants evaluated according to the DSM-IV-TR criteria at 24 months and categorized as ASD-positive or ASD-negative were further stratified by empirically derived cutoff scores using the Autism Diagnostic Observation Schedule yielding four groups: HR-ASD-High, HR-ASD-Moderate (HR-ASD-Mod), HR-ASD-Negative (HR-Neg), and LR-ASD-Negative (LR-Neg). RESULTS: The four groups demonstrated different developmental trajectories that became increasingly distinct from 6 to 24 months across all domains. At 6 months, the HR-ASD-High group demonstrated less advanced Gross Motor and Visual Reception skills compared with the LR-Neg group. By 12 months, the HR-ASD-High group demonstrated increased behavioral features of ASD and decreased cognitive and adaptive functioning compared to the HR-Neg and LR-Neg groups. By 24 months, both the HR-ASD-High and HR-ASD-Moderate groups demonstrated differences from the LR- and HR-Neg groups in all domains. CONCLUSIONS: These findings reveal atypical sensorimotor development at 6 months of age which is associated with ASD at 24 months in the most severely affected group of infants. Sensorimotor differences precede the unfolding of cognitive and adaptive deficits and behavioral features of autism across the 6- to 24-month interval. The less severely affected group demonstrates later symptom onset, in the second year of life, with initial differences in the social-communication domain.

DAWSON, Auteur ; A. ESTES, Auteur Article en page(s) : p.276-283 Langues : Anglais (eng) Mots-clés : Academic achievement Autism Inhibition Math Set shifting Working memory Index. décimale : PER Périodiques Résumé : The contributions of Executive Function (EF) to academic achievement in children with Autism Spectrum Disorder (ASD) are not well understood. Academic achievement and its association with EF is described in 32, 9-year-old children with ASD. EF at age 6 and 9, and academic achievement at age 9 were assessed as part of a larger longitudinal study. Better performance on a Spatial Reversal task but not A-not-B with Invisible Displacement at age 6 was associated with better math achievement at age 9. No relationship was found between these EF measures at age 6 and reading or spelling achievement at age 9. Future studies are needed to explore whether improving early EF skills can increase math achievement in children with ASD.

SIKICH, Auteur Article en page(s) : p.1727-1737 Langues : Anglais (eng) Mots-clés : Attention deficit/hyperactivity disorder Comorbidity Executive function Go/No-Go Inhibition Neurodevelopmental disorder Index. décimale : PER Périodiques Résumé : The presence of attention deficit/hyperactivity disorder (ADHD) symptoms in children with autism spectrum disorder (ASD) is associated with worse cognitive control. Children with ASD and ADHD often respond poorly to medications, thus we need alternative treatments. We examined the feasibility, acceptability, and preliminary efficacy of Project Evo-a digital treatment. Nineteen children with ASD and co-occurring ADHD symptoms completed this app-based treatment that targets multi-tasking through gameplay versus a comparison educational treatment. Children had a high engagement with both treatments, and parents and children reported high acceptability. Within-group analyses suggest the multi-tasking but not the educational treatment may improve cognitive control. This multi-tasking treatment is feasible, acceptable, and possibly efficacious for cognitive control impairments in children with ASD and ADHD.
