Atypical perception in autism: A failure of perceptual specialization? / Bat-Sheva HADAD in Autism Research, 10-9 (September 2017)
[article]
Titre : Atypical perception in autism: A failure of perceptual specialization? Type de document : Texte imprimé et/ou numérique Auteurs : Bat-Sheva HADAD, Auteur ; Eugenia K. GOLDSTEIN, Auteur ; Natalie N. RUSSO, Auteur Article en page(s) : p.1510-1522 Langues : Anglais (eng) Mots-clés : ASD autism perception perceptual specialization color perception separable and integral perception predictive coding Index. décimale : PER Périodiques Résumé : We examined whether reduced perceptual specialization underlies atypical perception in autism spectrum disorder (ASD) testing classifications of stimuli that differ either along integral dimensions (prototypical integral dimensions of value and chroma), or along separable dimensions (prototypical separable dimensions of value and size). Current models of the perception of individuals with an ASD would suggest that on these tasks, individuals with ASD would be as, or more, likely to process dimensions as separable, regardless of whether they represented separable or integrated dimensions. In contrast, reduced specialization would propose that individuals with ASD would respond in a more integral manner to stimuli that differ along separable dimensions, and at the same time, respond in a more separable manner to stimuli that differ along integral dimensions. A group of nineteen adults diagnosed with high functioning ASD and seventeen typically developing participants of similar age and IQ, were tested on speeded and restricted classifications tasks. Consistent with the reduced specialization account, results show that individuals with ASD do not always respond more analytically than typically developed (TD) observers: Dimensions identified as integral for TD individuals evoke less integral responding in individuals with ASD, while those identified as separable evoke less analytic responding. These results suggest that perceptual representations are more broadly tuned and more flexibly represented in ASD.

Titre : Individuals with autism show non-adaptive relative weighting of perceptual prior and sensory reliability Type de document : Texte imprimé et/ou numérique Auteurs : Nahal BINUR, Auteur ; Hagit HEL-OR, Auteur ; Bat-Sheva HADAD, Auteur Article en page(s) : p.2052-2065 Langues : Anglais (eng) Mots-clés : Humans Autistic Disorder Autism Spectrum Disorder Reproducibility of Results Bayesian perception autism spectrum disorder inferred perception perceptual illusions width-height illusion Index. décimale : PER Périodiques Résumé : Unique perceptual skills and abnormalities in perception have been extensively demonstrated in those with autism for many perceptual domains, accounting, at least in part, for some of the main symptoms. Several new hypotheses suggest that perceptual representations in autism are unrefined, appear less constrained by exposure and regularities of the environment, and rely more on actual concrete input. Consistent with these emerging views, a bottom-up, data-driven fashion of processing has been suggested to account for the atypical perception in autism. It is yet unclear, however, whether reduced effects of prior knowledge and top-down information, or rather reduced noise in the sensory input, account for the often-reported bottom-up mode of processing in autism. We show that neither is sufficiently supported. Instead, we demonstrate clear differences between autistics and neurotypicals in how incoming input is weighted against prior knowledge and experience in determining the final percept. Importantly, the findings tap central differences in perception between those with and without autism that are consistent across identified sub-clusters within each group.

However, the mechanisms underlying these deficiencies are unclear. Therefore, we examined the social information processing (SIP) patterns and social behaviors of 25 preschool children with ASDs in comparison to a matched group of 25 typically developing children. We found children with ASDs to be less likely than typically developing children to efficiently encode social information, to positively construct and evaluate competent responses, and to exhibit prosocial behaviors. They were also more likely than typically developing children to attribute hostile intentions to others in benign social situations, to construct and evaluate more positively aggressive responses, to construct more avoidant responses, and to display more externalizing behaviors. Interestingly, counterintuitive patterns of relationships were found within the ASD group with more competent SIP and theory of mind (ToM) patterns relating to less competent social behaviors. Finally, within the ASD group, more competent SIP patterns were found to be significantly related to higher ToM capacities.

Titre : Strong Bias Towards Analytic Perception in ASD Does not Necessarily Come at the Price of Impaired Integration Skills Type de document : Texte imprimé et/ou numérique Auteurs : Bat-Sheva HADAD, Auteur ; Yair ZIV, Auteur Article en page(s) : p.1499-1512 Langues : Anglais (eng) Mots-clés : Global–local processing Weak central coherence (WCC) Enhanced perceptual functioning (EPF) ASD Holistic-analytic processing Contour integration Index. décimale : PER Périodiques Résumé : We first demonstrated analytic processing in ASD under conditions in which integral processing seems mandatory in TD observers, a pattern that is often taken to indicate a local default processing in ASD. However, this processing bias does not inevitably come at the price of impaired integration skills. Indeed, examining the same group of individuals with ASD on a task with explicit demands for integrated representations, Experiment 2 showed that the same observers with ASD demonstrated intact spatial integration. The results further showed that performance was not only quantitatively, but also qualitatively comparable to that of TD observers, demonstrating the sensitivity of integration in ASD to the same interactive effects of Gestalt cues.
