Sensory hypersensitivity predicts repetitive behaviours in autistic and typically-developing children / S. E. SCHULZ in Autism, 23-4 (May 2019)
[article]
Titre : Sensory hypersensitivity predicts repetitive behaviours in autistic and typically-developing children Type de document : Texte imprimé et/ou numérique Auteurs : S. E. SCHULZ, Auteur ; R. A. STEVENSON, Auteur Article en page(s) : p.1028-1041 Langues : Anglais (eng) Mots-clés : autism spectrum disorder repetitive behaviours restricted interests sensory hypersensitivity sensory processing Index. décimale : PER Périodiques Résumé : The objective of this study was to examine the relationship between sensory hypersensitivity and restricted interests and repetitive behaviours associated with autism spectrum disorder and their typically-developing peers. Furthermore, the aims included the examination of the relationship across sensory modalities and various types of restricted interests and repetitive behaviours. Data were collected from the parents of 114 children: 49 of whom were diagnosed with autism spectrum disorder and 65 typically-developing children. Parents completed the Sensory Profile 2 - Child Version and the Repetitive Behaviours Questionnaire, Second Edition. The results suggested that sensory hypersensitivity is strongly related to the core autism spectrum disorder symptom of repetitive behaviours. This relationship was not specific to autism spectrum disorder; repetitive behaviours significantly increased with sensory hypersensitivity in typically-developing individuals as well. This effect was consistent across all modalities in both autism spectrum disorder and typically developing groups; group differences were observed in the oral and tactile modalities. Furthermore, sensory hypersensitivity was significantly predictive of repetitive behaviours in all participants, autism spectrum disorder and typically-developing, and importantly, autism spectrum disorder diagnosis did not add any predictive influence above and beyond sensory hypersensitivity. Finally, sensory hypersensitivity was significantly predictive of all subdomains of repetitive behaviours, including repetitive motor movements, rigidity and adherence to routine, preoccupation with restricted patterns of interest and unusual sensory interests, and diagnosis added no predictive ability beyond sensory hypersensitivity.

Titre : Neurophysiological hyperresponsivity to sensory input in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Y. TAKARAE, Auteur ; S. R. SABLICH, Auteur ; S. P. WHITE, Auteur ; J. A. SWEENEY, Auteur Article en page(s) : p.29 Langues : Anglais (eng) Mots-clés : Autism Contrast sensitivity Heterogeneity Individual differences Sensory hypersensitivity Index. décimale : PER Périodiques Résumé : BACKGROUND: Atypical sensory processing is a common clinical observation in autism spectrum disorder (ASD). Neural hyperexcitability has been suggested as the cause for sensory hypersensitivity, a frequently reported clinical observation in ASD. We examined visual evoked responses to parametric increases in stimulus contrast in order to model neural responsivity of sensory systems in ASD. METHODS: Thirteen high-functioning individuals with ASD and 12 typically developing (TD) individuals completed a steady-state visual evoked potential study. Stimuli were vertical circular gratings oscillating at 3.76 Hz at varying contrasts (5, 10, 20,..., 90 % contrast, 10 levels). The average spectral power at the stimulus oscillation frequency was calculated for each contrast level. RESULTS: The magnitude of evoked sensory responses increased at a significantly greater rate and resulted in disproportionately elevated activation with higher contrasts in the ASD group. Approximately 45 % of ASD participants had rates of response increases greater than any TD participant. This alteration was highly associated with parental reports of these participants' sensory difficulties. CONCLUSIONS: Greater increases in visual responses over contrast manipulation suggest heightened excitability in the sensory cortex in ASD participants. Heightened neural excitability was observed in a substantial portion but not all of the ASD participants. This pattern suggests that individuals with higher excitability may constitute a neurobiologically distinct subgroup requiring individualized treatment interventions.

Titre : Over-Responsiveness and Greater Variability in Roughness Perception in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Sarah M. HAIGH, Auteur ; Nancy MINSHEW, Auteur ; David J. HEEGER, Auteur ; Ilan DINSTEIN, Auteur ; Marlene BEHRMANN, Auteur Article en page(s) : p.393-402 Langues : Anglais (eng) Mots-clés : autism tactile variability sensory hypersensitivity Index. décimale : PER Périodiques Résumé : Although sensory problems, including tactile hypersensitivity and hyposensitivity (DSM-5) are commonly associated with autism, there is a dearth of systematic and rigorous research in this domain. Here, we report findings from a psychophysical experiment that explored differences in tactile perception between individuals with autism and typically developing control participants, who, using their index finger, rated a series of surfaces on the extent of their roughness. Each surface was rated multiple times and we calculated both the average rating and the variability across trials. Relative to controls, the individuals with autism perceived the surfaces as rougher overall and exhibited greater variability in their ratings across trials. These findings characterize altered tactile perception in autism and suggest that sensory problems in autism may be the product of overly responsive and variable sensory processing.
