Developing Social Communication Skills Using Dual First-Person Video Recording Glasses: A Novel Intervention for Adolescents with Autism / Sarah HURWITZ in Journal of Autism and Developmental Disorders, 50-3 (March 2020)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 50-3 (March 2020) . - p.904-915 Titre : Developing Social Communication Skills Using Dual First-Person Video Recording Glasses: A Novel Intervention for Adolescents with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Sarah HURWITZ, Auteur ; Tybytha RYAN, Auteur ; Daniel P KENNEDY, Auteur Article en page(s) : p.904-915 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Conversation  Multiple baseline design  Social skills  Video recording glasses  Video self-modeling Index. décimale : PER Périodiques Résumé : Adolescents with autism often experience pronounced difficulties with social communication, and novel interventions designed to improve core abilities are greatly needed. This study examines if providing immediate video feedback, an extension of video self-modeling, can aid adolescents with autism to self-identify strengths and irregularities from their social interactions. Using multiple baseline design across four participants, individuals engaged in naturalistic conversations wearing video recording glasses. During the intervention, videos were reviewed immediately and participants recognized when they were not following typical social-communicative convention. Based on observational data coded from videos, all four participants modified their behavior during subsequent conversations. Although adolescents with autism may hypothetically know to behave, viewing themselves on video may provide practical cues to support social insight and behavioral change.

Estimation of the prevalence of autism spectrum disorder in South Korea, revisited / Peter C. PANTELIS in Autism, 20-5 (July 2016)  

Public ISBD [article]  inAutism > 20-5 (July 2016) . - p.517-527 Titre : Estimation of the prevalence of autism spectrum disorder in South Korea, revisited Type de document : Texte imprimé et/ou numérique Auteurs : Peter C. PANTELIS, Auteur ; Daniel P KENNEDY, Auteur Article en page(s) : p.517-527 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  epidemiology  prevalence  two-phase screening Index. décimale : PER Périodiques Résumé : Two-phase designs in epidemiological studies of autism prevalence introduce methodological complications that can severely limit the precision of resulting estimates. If the assumptions used to derive the prevalence estimate are invalid or if the uncertainty surrounding these assumptions is not properly accounted for in the statistical inference procedure, then the point estimate may be inaccurate and the confidence interval may not be a true reflection of the precision of the estimate. We examine these potential pitfalls in the context of a recent high-profile finding by Kim et al. (2011, Prevalence of autism spectrum disorders in a total population sample. American Journal of Psychiatry 168: 904–912), who estimated that autism spectrum disorder affects 2.64% of children in a South Korean community. We reconstructed the study’s methodology and used Monte Carlo simulations to analyze whether their point estimate and 95% confidence interval (1.91%, 3.37%) were reasonable, given what was known about their screening instrument and sample. We find the original point estimate to be highly assumption-dependent, and after accounting for sources of uncertainty unaccounted for in the original article, we demonstrate that a more reasonable confidence interval would be approximately twice as large as originally reported. We argue that future studies should give serious consideration to the additional sources of uncertainty introduced by a two-phase design, which may easily outstrip any expected gains in efficiency.

The influence of presentation modality on the social comprehension of naturalistic scenes in adults with autism spectrum disorder / Haley M GEDEK in Autism, 22-2 (February 2018)  

Public ISBD [article]  inAutism > 22-2 (February 2018) . - p.205-215 Titre : The influence of presentation modality on the social comprehension of naturalistic scenes in adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Haley M GEDEK, Auteur ; Peter C. PANTELIS, Auteur ; Daniel P KENNEDY, Auteur Année de publication : 2018 Article en page(s) : p.205-215 Langues : Anglais (eng) Mots-clés : autism spectrum disorder,emotion recognition,high-functioning autism,multisensory integration,social comprehension Index. décimale : PER Périodiques Résumé : The comprehension of dynamically unfolding social situations is made possible by the seamless integration of multimodal information merged with rich intuitions about the thoughts and behaviors of others. We examined how high-functioning adults with autism spectrum disorder and neurotypical controls made a complex social judgment (i.e. rating the social awkwardness of scenes from a television sitcom) across three conditions that manipulated presentation modality—visual alone, transcribed text alone, or visual and auditory together. The autism spectrum disorder and control groups collectively assigned similar mean awkwardness ratings to individual scenes. However, individual participants with autism spectrum disorder tended to respond more idiosyncratically than controls, assigning ratings that were less correlated with the ratings of the other participants in the sample. We found no evidence that this group difference was isolated to any specific presentation modality. In a comparison condition, we found no group differences when participants instead rated the happiness of characters (a more basic social judgment) in full audiovisual format. Thus, although we observed differences in the manner with which high-functioning adults with autism spectrum disorder make social judgments compared to controls, these group differences may be dependent on the social dimension being judged, rather than the specific modality of presentation.

Visual Disengagement: Genetic Architecture and Relation to Autistic Traits in the General Population / Monica SIQUEIROS SANCHEZ in Journal of Autism and Developmental Disorders, 50-6 (June 2020)

In this study we used twin modelling to assess the role of genetics in basic measures of visual disengagement, and tested their putative association to autistic traits in the general population. We used the Gap Overlap task in a sample of 492 twins. Results showed that most of the covariance among eye movement latencies across conditions was shared and primarily genetic. Further, there were unique genetic contributions to the Gap condition, but not to the Overlap condition-i.e. the one theorized to capture visual disengagement. We found no phenotypic association between autistic traits and disengagement, thus not supporting the hypothesis of visual disengagement as an endophenotype for autistic traits.

Volitional eye movement control and ADHD traits: a twin study / Monica SIQUEIROS SANCHEZ in Journal of Child Psychology and Psychiatry, 61-12 (December 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-12 (December 2020) . - p.1309-1316 Titre : Volitional eye movement control and ADHD traits: a twin study Type de document : Texte imprimé et/ou numérique Auteurs : Monica SIQUEIROS SANCHEZ, Auteur ; Terje FALCK-YTTER, Auteur ; Daniel P KENNEDY, Auteur ; Sven BÖLTE, Auteur ; Paul LICHTENSTEIN, Auteur ; Brian M.

In this twin study, we examined the relation between performance on a response inhibition eye-tracking paradigm and parent-rated ADHD traits in a population-based twin sample. We hypothesized that altered eye movement control is associated with the severity of ADHD traits and that this association is attributable to genetic factors. METHODS: A total of 640 twins (320 pairs, 50% monozygotic) aged 9-14 years) from the Child and Adolescent Twin Study in Sweden (CATSS) participated. Twins performed the antisaccade task indexing inhibitory alterations as either direction errors (following exogenous cues rather than instructions) or premature anticipatory eye movements (failure to wait for cues). We calculated the associations of eye movement control and ADHD traits using linear regression mixed-effects models and genetic and environmental influences with multivariate twin models. RESULTS: Premature anticipatory eye movements were positively associated with inattentive traits (? = .17; 95% CI: 0.04, 0.31), while controlling for hyperactive behaviors and other covariates. Both premature anticipatory eye movements and inattention were heritable (h(2)  = 0.40, 95% CI: 0.22, 0.56; h(2)  = 0.55; 95% CI: 0.42, 0.65; respectively), and their genetic correlation was small but statistically significant (r = .19, 95% CI: 0.02, 0.36). However, the genetic correlation did not remain significant after adjusting for covariates (age, sex, hyperactivity traits, IQ). No link was found between direction errors and ADHD traits. CONCLUSIONS: This study indicates that there is a specific, genetically influenced, relation between top-down eye movement control and the inattentive traits typical of ADHD.
