Responses to the Brazilian Portuguese version of the Emotional Outburst Questionnaire were collected from 327 caregivers of young people (6-25 years) with autism spectrum disorder, Down?s syndrome, or intellectual disability. Responses were compared to a previous sample of 268 responses from the English version of the questionnaire. The latent factor structure of the contextual items was measurement invariant across both versions. The Brazilian responses were classified into three distinct clusters (Sensory Sensitivity; Perceived Safety; Perceived Unsafety) which considerably overlapped with the English clusters.

Dynamic functional connectivity in the right temporoparietal junction captures variations in male autistic trait expression / Laura BRAVO BALSA in Autism Research, 17-4 (April 2024)  

Public ISBD [article]  inAutism Research > 17-4 (April 2024) . - p.702-715 Titre : Dynamic functional connectivity in the right temporoparietal junction captures variations in male autistic trait expression Type de document : Texte imprimé et/ou numérique Auteurs : Laura BRAVO BALSA, Auteur ; Ahmad ABU-AKEL, Auteur ; Carmel MEVORACH, Auteur Article en page(s) : p.702-715 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Autistic individuals can experience difficulties with attention reorienting and Theory of Mind (ToM), which are closely associated with anterior and posterior subdivisions of the right temporoparietal junction. While the link between these processes remains unclear, it is likely subserved by a dynamic crosstalk between these two subdivisions. We, therefore, examined the dynamic functional connectivity (dFC) between the anterior and posterior temporoparietal junction, as a biological marker of attention and ToM, to test its contribution to the manifestation of autistic trait expression in Autism Spectrum Condition (ASC). Two studies were conducted, exploratory (14 ASC, 15 TD) and replication (29 ASC, 29 TD), using resting-state fMRI data and the Social Responsiveness Scale (SRS) from the Autism Brain Imaging Data Exchange repository. Dynamic Independent Component Analysis was performed in both datasets using the CONN toolbox. An additional sliding-window analysis was performed in the replication study to explore different connectivity states (from highly negatively to highly positively correlated). Dynamic FC was reduced in ASC compared to TD adults in both the exploratory and replication datasets and was associated with increased SRS scores (especially in ASC). Regression analyses revealed that decreased SRS autistic expression was predicted by engagement of highly negatively correlated states, while engagement of highly positively correlated states predicted increased expression. These findings provided consistent evidence that the difficulties observed in ASC are associated with altered patterns of dFC between brain regions subserving attention reorienting and ToM processes and may serve as a biomarker of autistic trait expression.

Hierarchical Processing in ASD is Driven by Exaggerated Salience Effects, not Local Bias / Ayelet BAISA in Journal of Autism and Developmental Disorders, 51-2 (February 2021)

Participants with ASD and typically developing controls performed a Navon letters task under conditions of global salience, local salience or equal salience of both levels. Results revealed no group differences in level of processing (global or local) and no local bias for ASD. Rather, both groups showed better performance when targets were more salient compared to when distractors were more salient. Importantly, participants with ASD exhibited increased sensitivity to salience at the distractor level. We conclude that inconsistent findings in the context of global/local processing in ASD may stem from such exaggerated salience effects.

Reduced distractor interference in neurotypical adults with high expression of autistic traits irrespective of stimulus type / Mayra MULLER SPANIOL in Autism Research, 11-10 (October 2018)  

Public ISBD [article]  inAutism Research > 11-10 (October 2018) . - p.e2005 Titre : Reduced distractor interference in neurotypical adults with high expression of autistic traits irrespective of stimulus type Type de document : Texte imprimé et/ou numérique Auteurs : Mayra MULLER SPANIOL, Auteur ; Lilach SHALEV, Auteur ; Carmel MEVORACH, Auteur Article en page(s) : p.e2005 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Attention atypicality is evident in autism spectrum disorder (ASD) and its broader phenotype with previous studies suggesting that in some cases participants can be more efficient at ignoring distracting irrelevant information. However, it is not clear to what extent this improved filtering capacity is driven by perceptual atypicality, such as local bias or atypical face processing, which is also sometimes reported in these populations. For instance, better ability to ignore the global aspect of a display could stem from a local perceptual bias rather than from improved distractor inhibition. To test whether distractor suppression per se, is associated with high expression of autistic traits, in the present study a large cohort of neurotypical participants (n = 218), in whom expression of autistic traits was assessed, performed two nonspatial attention selection tasks with different categories of stimuli (global/local and face/scene). Importantly, both tasks involved a conflict with one aspect of the stimuli designated as the target and the other designated as the distractor. Across the two experiments adults with high autistic traits were overall, better able to ignore distractors than adults with low autistic traits, irrespective of the type of perceptual processing involved. These results support the notion that autistic tendencies are associated with increased attention filtering (at least when target and distractor remain constant) which is not dependent on perceptual biases. Thus, future work in the broader autism phenotype should explicitly consider the effect played by attention mechanisms in this population. Autism Res 2018, 11: 1345–1355. © 2018 International Society for Autism Research, Wiley Periodicals, Inc. Lay Summary In the present study, we show that neurotypical adults with high autistic traits are better able to avoid distraction from conspicuous (but completely irrelevant) distractors when told in advance to do so. This ability is not affected by the type of visual input (for instance, whether the distractor is a face or whether small rather than large letters should be reported). This finding could be important in better understanding the way attention is utilized in Autism.
