Color Afterimages in Autistic Adults / J. MAULE in Journal of Autism and Developmental Disorders, 48-4 (April 2018)
[article]
Titre : Color Afterimages in Autistic Adults Type de document : Texte imprimé et/ou numérique Auteurs : J. MAULE, Auteur ; K. STANWORTH, Auteur ; E. PELLICANO, Auteur ; A. FRANKLIN, Auteur Article en page(s) : p.1409-1421 Langues : Anglais (eng) Mots-clés : Adaptation Afterimages Autism Color Top-down knowledge Index. décimale : PER Périodiques Résumé : It has been suggested that attenuated adaptation to visual stimuli in autism is the result of atypical perceptual priors (e.g., Pellicano and Burr in Trends Cogn Sci 16(10):504-510, 2012. doi: 10.1016/j.tics.2012.08.009 ). This study investigated adaptation to color in autistic adults, measuring both strength of afterimage and the influence of top-down knowledge. We found no difference in color afterimage strength between autistic and typical adults. Effects of top-down knowledge on afterimage intensity shown by Lupyan (Acta Psychol 161:117-130, 2015. doi: 10.1016/j.actpsy.2015.08.006 ) were not replicated for either group. This study finds intact color adaptation in autistic adults. This is in contrast to findings of attenuated adaptation to faces and numerosity in autistic children. Future research should investigate the possibility of developmental differences in adaptation and further examine top-down effects on adaptation.

Titre : Ensemble perception of color in autistic adults Type de document : Texte imprimé et/ou numérique Auteurs : John MAULE, Auteur ; Kirstie STANWORTH, Auteur ; Elizabeth PELLICANO, Auteur ; Anna FRANKLIN, Auteur Article en page(s) : p.839-851 Langues : Anglais (eng) Mots-clés : autism color ensemble perception visual perception priors global processing Index. décimale : PER Périodiques Résumé : Dominant accounts of visual processing in autism posit that autistic individuals have an enhanced access to details of scenes [e.g., weak central coherence] which is reflected in a general bias toward local processing. Furthermore, the attenuated priors account of autism predicts that the updating and use of summary representations is reduced in autism. Ensemble perception describes the extraction of global summary statistics of a visual feature from a heterogeneous set (e.g., of faces, sizes, colors), often in the absence of local item representation. The present study investigated ensemble perception in autistic adults using a rapidly presented (500 msec) ensemble of four, eight, or sixteen elements representing four different colors. We predicted that autistic individuals would be less accurate when averaging the ensembles, but more accurate in recognizing individual ensemble colors. The results were consistent with the predictions. Averaging was impaired in autism, but only when ensembles contained four elements. Ensembles of eight or sixteen elements were averaged equally accurately across groups. The autistic group also showed a corresponding advantage in rejecting colors that were not originally seen in the ensemble. The results demonstrate the local processing bias in autism, but also suggest that the global perceptual averaging mechanism may be compromised under some conditions. The theoretical implications of the findings and future avenues for research on summary statistics in autism are discussed.

Participants used mutual exclusivity to fast map novel word-picture relationships and retention was assessed following a 5-min delay. Children with ASD achieved significantly greater retention accuracy when learning from photographs rather than cartoons and, surprisingly, responded more accurately than TD children when learning from photographs. Our results demonstrate that children with ASD benefit from greater iconicity when learning words from pictures, providing a data-grounded rationale for using colour photographs when administering picture-based interventions.
