Is it avoidance or hypoarousal? A systematic review of emotion recognition, eye-tracking, and psychophysiological studies in young adults with autism spectrum conditions / Hélio Clemente CUVE in Research in Autism Spectrum Disorders, 55 (November 2018)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 55 (November 2018) . - p.1-13 Titre : Is it avoidance or hypoarousal? A systematic review of emotion recognition, eye-tracking, and psychophysiological studies in young adults with autism spectrum conditions Type de document : Texte imprimé et/ou numérique Auteurs : Hélio Clemente CUVE, Auteur ; Yu GAO, Auteur ; Akiko FUSE, Auteur Article en page(s) : p.1-13 Langues : Anglais (eng) Mots-clés : Autism  Emotion  Eye-tracking  Arousal  Two-pathway  Model  Alexithymia Index. décimale : PER Périodiques Résumé : A systematic review was conducted for studies exploring the link between gaze patterns, autonomic arousal and emotion recognition deficits (ERD) in young adults with Autism Spectrum Conditions (ASC) in the context of the eye-avoidance/hyperarousal and the orientation/hypoarousal hypotheses. These hypotheses suggest that ERD in ASC can be explained by either exacerbated physiological arousal to eye-contact interfering with emotion recognition, or blunted arousal not engaging the necessary attention and awareness mechanisms to process emotionally salient cues, respectively. Most studies have suggested that individuals with ASC display an overall reduced attention to the eyes, however, this was not always associated with ERD, and some studies also reported ERD with no evidence of atypical gaze patterns. The evidence from psychophysiological studies is also mixed. While some studies supported that individuals with ASC are hypoaroused during emotion processing, others reported hyperarousal or even partially supported both. Overall, these results suggest that the current autonomic arousal and gaze hypotheses cannot fully account for ERD in ASC. A new integrative model is proposed, suggesting a two-pathway mechanism, in which avoidance and orientation processes might independently lead to ERD in ASC. Current methodological limitations, the influence of alexithymia, and implications are discussed.

The intervention priorities of parents of children with autism spectrum disorders in Iran / Mehdi GHANADZADE in Research in Autism Spectrum Disorders, 55 (November 2018)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 55 (November 2018) . - p.14-24 Titre : The intervention priorities of parents of children with autism spectrum disorders in Iran Type de document : Texte imprimé et/ou numérique Auteurs : Mehdi GHANADZADE, Auteur ; Mitzi WALTZ, Auteur ; Tehnaz RAGI, Auteur Article en page(s) : p.14-24 Langues : Anglais (eng) Mots-clés : Autism  Intervention  Priorities  Parents  LMICs Index. décimale : PER Périodiques Résumé : When designing and implementing evidence-based programs for children with an autism spectrum disorder, the intervention priorities of parents are important criteria. Although studies in developed countries have explored parents’ intervention priorities, there is a paucity of this kind of research in developing countries. This research explores the intervention priorities of 207 Iranian parents for their children with autism in Tehran, the capital of Iran. Participants with children between 2 to 21 years of age were asked to rate their intervention priorities from among 10 main categories. In addition, correlations between children’s difficulties and parental intervention priorities were examined. The results indicate that building social communication skills was the highest intervention priority for parents of Iranian children with autism, a contrast to typical current service provision in Iran. The results also substantiated that presence of social communication difficulties and challenging behaviors in children are typically correlated with parents' intervention priorities.

Exploring the nature of anxiety in young adults on the autism spectrum: A qualitative study / Andrew T. HALIM in Research in Autism Spectrum Disorders, 55 (November 2018)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 55 (November 2018) . - p.25-37 Titre : Exploring the nature of anxiety in young adults on the autism spectrum: A qualitative study Type de document : Texte imprimé et/ou numérique Auteurs : Andrew T. HALIM, Auteur ; Amanda L. RICHDALE, Auteur ; Mirko ULJAREVIC, Auteur Article en page(s) : p.25-37 Langues : Anglais (eng) Mots-clés : Adults  ASD  Anxiety  Thematic analysis  Qualitative study Index. décimale : PER Périodiques Résumé : Background Research exploring the nature of anxiety symptoms in autism spectrum disorder (ASD) has thus far focused on children and adolescents, providing evidence for both typical and atypical anxiety symptom presentations associated with ASD. This study builds on previous research by focusing on young adults, and comparing anxiety presentation between individuals with ASD and non-ASD individuals with anxiety disorders. We anticipated that while the non-ASD group would report only typical anxiety symptoms, and the ASD group would report both typical and atypical presentations of anxiety symptoms. Method Ten individuals with ASD and anxiety (M?=?21.8?years, SD?=?6.76), and 10 individuals with anxiety (M?=?24.4?years, SD?=?4.17) participated in focus groups. Participants responded to semi-structured interview questions specifically developed using the DSM-5 criteria for each of the anxiety disorders, Illness Anxiety Disorder, and Obsessive-Compulsive Disorder. These questions focused on carefully elucidating experiences of anxiety including DSM-5 anxiety symptomatology and ASD-specific anxiety symptomatology. Results Thematic analysis revealed a theme structure for the ASD group composed of both DSM-5-related (e.g., social anxiety themes) and ASD-specific anxiety presentations (i.e., related to core ASD symptomatology). In contrast, the non-ASD group described predominantly DSM-5-related anxiety symptomatology. Conclusions Our findings support the predicted outcome that there are both ASD-specific anxiety and DSM-5-related anxiety symptomatology in young adults with ASD, compared with young adults with anxiety who show only DSM-5 symptomatology. Future research elucidating the relationship between ASD symptomatology and anxiety in ASD, utilising both quantitative and qualitative measures, is crucial to enable a more comprehensive understanding of the nuances of anxiety in ASD. Gaining this knowledge is a crucial step for the development of more accurate and appropriate assessment and treatment tools that can target their specific anxiety experiences.

Language abilities in monolingual- and bilingual- exposed children with autism or other developmental disorders / Yael G. DAI in Research in Autism Spectrum Disorders, 55 (November 2018)

FEIN, Auteur Article en page(s) : p.38-49 Langues : Anglais (eng) Mots-clés : Autism  Bilingual  Language ability  Developmental delay Index. décimale : PER Périodiques Résumé : Background Parents and providers are sometimes concerned that exposure to two languages will impair language acquisition in children with autism spectrum disorder (ASD) or other developmental disorders (DD). However, research to date suggests that language milestones and abilities are unaffected by this exposure. The current study explored language abilities in toddlers with ASD or DD exposed to one versus multiple languages, prior to intervention. To our knowledge, this is the largest investigation of language learning in bilingual-exposed (BE) children with ASD. Methods Participants were 388 children evaluated as part of a larger study on the early detection of ASD. Parents were asked to list all languages that primary caretakers use to communicate with their child. One hundred six BE children (57 ASD, 49 DD) were compared to 282 monolingual-exposed (ME) children (176 ASD, 106 DD). The Mullen Scales of Early Learning assessed nonverbal and verbal abilities. Multiple regression was used to evaluate the relationship of BE to language abilities, beyond the influence of nonverbal cognitive abilities, diagnosis, and socioeconomic status. Results Results showed greater language impairment in ASD than DD, but no main effect for language exposure group nor any interaction of language group by diagnosis. Results remained consistent after controlling for socioeconomic status. Conclusion This study suggests that bilingual caregivers can communicate with their children in both languages without adverse effects on their children’s language functioning.

In this paper, we investigate the same interactive association with ASD while adjusting for the mixture of four metals (lead, mercury, cadmium, and arsenic). Method We used data from 163 case-control pairs of children 2–8 years of age from our autism project in Jamaica, in which we collected blood for heavy metals analysis at enrollment. To minimize potential multicollinearity between concentrations of the four metals, we generated a mixture index using generalized weighted quantile sum regression, which was used in conditional logistic regression models to control for the four metals while assessing the interactive association between GSTP1 and BMC with ASD. Results Similar to the findings we reported previously, we found that in co-dominant and dominant models for GSTP1, among children with the Ile/Ile genotype, those with BMC???12??g/L had 4.6 and 4.27 times higher odds of ASD compared to those with BMC?
