Combining strengths and weaknesses in visual perception of children with an autism spectrum disorder: Perceptual matching of facial expressions / Kris EVERS in Research in Autism Spectrum Disorders, 5-4 (October-December 2011)

Titre : Combining strengths and weaknesses in visual perception of children with an autism spectrum disorder: Perceptual matching of facial expressions Type de document : Texte imprimé et/ou numérique Auteurs : Kris EVERS, Auteur ; Ilse L.J. NOENS, Auteur ; Jean STEYAERT, Auteur ; Johan WAGEMANS, Auteur Année de publication : 2011 Article en page(s) : p.1327-1342 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder (ASD) Matching Facial emotional expressions Compensation strategy Weak central coherence Enhanced perceptual functioning Index. décimale : PER Périodiques Résumé : Background
Children with an autism spectrum disorder (ASD) are known to have an atypical visual perception, with deficits in automatic Gestalt formation and an enhanced processing of visual details. In addition, they are sometimes found to have difficulties in emotion processing.
Methods
In three experiments, we investigated whether 7-to-11-year old children with ASD were showing superiorities or deficits in matching tasks that required focusing on faces with an emotional expression. Throughout these experiments, we increased the complexity of the stimuli and tasks demands.
Results and conclusions
In matching faces with emotional expressions, children with ASD were not able to show superior processing of details in any of the three experiments. They were able to compensate their inferior processing of emotions in some of the experiments (e.g., by using a slower, more sequential processing style). However, when stimulus complexity (e.g., dynamic facial expressions) or task demands (e.g., extracting and remembering the relevant stimulus dimension) increased, they were no longer able to do so, and they did show performance deficits.En ligne : http://dx.doi.org/10.1016/j.rasd.2011.01.004 Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=125

Titre : Implicit and explicit understanding of ambiguous figures by adolescents with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Melissa L. ALLEN, Auteur ; Alison CHAMBERS, Auteur Année de publication : 2011 Article en page(s) : p.457-472 Langues : Anglais (eng) Mots-clés : ambiguous figures conceptual copying enhanced perceptual functioning representation Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorder (ASD) can process both interpretations of an ambiguous figure (e.g. rabbit/duck) when told about the ambiguity, however they tend not to do so spontaneously. Here we show that although adolescents with ASD can explicitly experience such ‘reversals’, implicit measures suggest they are conceptually processing the images differently from learning disabled peers. Participants copied the same ambiguous figures under different contextual conditions, both before and after reversal experience. Results suggest that adolescents with ASD are not influenced by contextual information when copying ambiguous drawings, since they produce similar pictures before and after reversal, compared with controls. This research has implications for how individuals with ASD understand multiple representations and supports the Enhanced Perceptual Functioning theory.

BLACK, Auteur ; Sharmila VAZ, Auteur ; Richard PARSONS, Auteur ; Torbjörn FALKMER, Auteur ; Julia S. Y. TANG, Auteur ; Susan MORRIS, Auteur ; Hoe LEE, Auteur ; Marita FALKMER, Auteur Article en page(s) : p.101417 Langues : Anglais (eng) Mots-clés : Eye tracking Local bias Weak central coherence Enhanced perceptual functioning Index. décimale : PER Périodiques Résumé : Background Atypical visual perception in individuals with Autism Spectrum Disorders (ASD) may contribute to superiority in disembedding tasks. Gaze behavior has provided some insights in to mechanisms underlying this purported superiority in children, however evidence is limited and requires additional investigation. Method The performance and gaze behavior of 27 adolescents with ASD and 27 matched typically developing (TD) peers were examined during the Figure Ground Subtest of the Test of Visual Perception Skills-third edition (TVPS-3). Results Compared to their TD counterparts, adolescents with ASD were no different in accuracy, however, had a longer response time. Differences in gaze behavior were also observed, characterized by adolescents with ASD spending less time viewing the incorrect and target figures, and spending a greater proportion of time viewing irrelevant areas of the stimuli compared to TD adolescents. Conclusions Results suggest that while altered visual perception was observed, this did not contribute to superiority in disembedding tasks in adolescents with ASD. Future research is required to elucidate conditions under which altered visual perception may contribute to behavioral superiority.
