Atypical sensory reactivity influences auditory attentional control in adults with autism spectrum disorders / Debra S. KARHSON in Autism Research, 9-10 (October 2016)
[article]
Titre : Atypical sensory reactivity influences auditory attentional control in adults with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Debra S. KARHSON, Auteur ; Edward J. GOLOB, Auteur Article en page(s) : p.1079-1092 Langues : Anglais (eng) Mots-clés : P50 P1 N100 autism attention EEG/ERP sensory reactivity Index. décimale : PER Périodiques Résumé : Frequent observations of atypical sensory reactivity in people with autism spectrum disorders (ASD) suggest that the perceptual experience of those on the Spectrum is dissimilar to neurotypicals. Moreover, variable attention abilities in people with ASD, ranging from good control to periods of high distractibility, may be related to atypical sensory reactivity. This study used auditory event-related potential (ERP) measures to evaluate top-down and bottom-up attentional processes as a function of perceptual load, and examined these factors with respect to sensory reactivity. Twenty-five age and IQ-matched participants (ASD: 22.5 year, SD?=?4.1 year; Controls: 22.8 year, SD?=?5.1 year) completed the Adolescent/Adult Sensory Profile prior to performing a modified 3-stimulus (target, non-target, and distractor) auditory oddball target detection task EEG was recorded during task completion. ERP analysis assessed early sensory processing (P50, ?50 ms latency; N100, ?100 ms latency), cognitive control (N200, ?200 ms latency), and attentional processing (P3a and P3b, ?300 ms latency). Behavioral data demonstrates participants with ASD and neurotypical performed similarly on auditory target detection, but diverged on sensory profiles. Target ERP measures associated with top-down control (P3b latency) significantly increased under greater load in controls, but not in participants with ASD. Early ERP responses associated with bottom-up attention (P50 amplitude) were positively correlated to increased sensory sensitivity. Findings suggest specific neural mechanisms for increased perceptual capacity and enhanced bottom-up processing of sensory stimuli in people with autism. Results from participants with ASD are consistent with load theory and enhanced perceptual functioning.

Parents of 143 infants who were at high- and low-risk for ASD rated their child's temperament traits when they were 9, 15 and 24 months old; they rated anxiety and ASD traits when they were 36 months old. The findings suggest that behavioural inhibition may be an early predictor of later anxiety in children with and without ASD and that lower levels of effortful control in children who later develop ASD may contribute to the higher expression of anxiety within this population.

E. SCHULZ, Auteur ; R. A. STEVENSON, Auteur Article en page(s) : p.121-134 Langues : Anglais (eng) Mots-clés : adults autism spectrum disorders behavioural measurement reactivity repetitive behaviours and interests sensitivity sensory impairments Index. décimale : PER Périodiques Résumé : Recent studies have suggested that individuals who exhibit heightened sensitivity also exhibit higher rates and severity of restricted interests and repetitive behaviours. This line of research has been conducted almost exclusively through caregiver reports of sensitivity. Here, a more rigorous psychophysics paradigm was applied to assess sensory sensitivity and relate hypersensitivity to restricted interests and repetitive behaviours. In addition, commonly used questionnaire measures of sensory sensitivity were collected to determine if self-reported measures accurately reflect behavioural measures of sensory sensitivity. In all, 90 typically developing participants completed a visual detection task, a questionnaire measure of sensory processing and a measure of restricted interests and repetitive behaviours. Visual sensitivity, measured both behaviourally and with questionnaires, is positively related to restricted interests and repetitive behaviours. Surprisingly, visual sensitivity as measured behaviourally and through self-report are unrelated. Furthermore, a regression analysis suggests that while restricted interests and repetitive behaviours can be predicted based on both behavioural and self-reported sensitivity, these two predictors account for different portions of the variance in restricted interests and repetitive behaviours. Thus, while these results provide evidence supporting the contribution of sensory sensitivity to restricted interests and repetitive behaviours, these results also indicate that behavioural and questionnaire measures of sensory sensitivity are measuring two distinct constructs. We hypothesize that behavioural measures are measuring sensory sensitivity, while questionnaires measures are in fact measuring sensory reactivity.

We compared the prevalence of parent-reported suicidality ideation and considered the role of emotion dysregulation in 330 psychiatric inpatient youth with ASD, 1169 community youth with ASD surveyed online, and 1000 youth representative of the US census. The prevalence of suicidal ideation was three and five times higher in the community and inpatient ASD samples, respectively, compared to the general US sample. In the ASD groups, greater emotion dysregulation was associated with suicidal ideation. Implications include consideration of emotion regulation as a potential mechanism and treatment target for suicidality in ASD.

Atypical emotion regulation (ER) may underlie these accompanying features. This special issue of the Journal of Autism and Developmental Disorders presents a series of mechanistic and applied papers on ER and emotional experiences in ASD. Important concepts for future research are discussed, including how to conceptualize emotion dysregulation in ASD, the importance of capturing variability in emotion dysregulation in ASD studies, and the promise of intervention approaches that target ER impairments. This special issue highlights the growing emphasis on ER and emotional distress in ASD, and aims to encourage continued research in this area given the potential for this line of inquiry to lead to improved outcomes.
