How Adolescents with Autism Spectrum Disorder (ASD) Spontaneously Attend to Real-World Scenes: Use of a Change Blindness Paradigm / M. HOCHHAUSER in Journal of Autism and Developmental Disorders, 48-2 (February 2018)
[article]
Titre : How Adolescents with Autism Spectrum Disorder (ASD) Spontaneously Attend to Real-World Scenes: Use of a Change Blindness Paradigm Type de document : Texte imprimé et/ou numérique Auteurs : M. HOCHHAUSER, Auteur ; Adi ARAN, Auteur ; O. GRYNSZPAN, Auteur Article en page(s) : p.502-510 Langues : Anglais (eng) Mots-clés : Adolescents Autism spectrum disorder Change blindness Visual attention Index. décimale : PER Périodiques Résumé : Visual attention of adolescents with autism spectrum disorder (ASD) was assessed using a change blindness paradigm. Twenty-five adolescents with ASD aged 12-18 years and 25 matched typically developing (TD) adolescents viewed 36 pairs of digitized real-world images. Each pair of images was displayed in a 'flicker paradigm' whereby a particular item alternately appeared and disappeared. This item was either a central or a marginal detail of the scene. Change detection response times were measured and compared between groups. Marginal details were more difficult to detect than central details of the scenes in both groups, however, the response times of the ASD group were lower than the TD group. These results challenge the hypothesis of superior visual detection in ASD.

Titre : Investigating attention in young adults with autism spectrum disorder (ASD) using change blindness and eye tracking Type de document : Texte imprimé et/ou numérique Auteurs : Michal HOCHHAUSER, Auteur ; Adi ARAN, Auteur ; Ouriel GRYNSZPAN, Auteur Article en page(s) : 101771 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Change blindness Eye tracking Social interaction Young adults Index. décimale : PER Périodiques Résumé : Background Social interaction at its core entails allocating attention to relevant stimuli. As such, the perception of change requires attention, but studies have suggested that the social impairment in people with autism spectrum disorder (ASD) occurs at the attentual level of "on-line" social cognition. Method Forty-four young adults—22 with autism spectrum disorder (ASD) and 22 with typical development (TD)—participated in two experiments. The first used a change blindness (CB) paradigm where attention was investigated through the detection of changed items with central and marginal levels of interest when viewing images of everyday scenarios. Eye-tracking was used to compare response times, first fixations and total fixation time on changes. The second used social films with eye tracking of gaze fixations. Results Participants with ASD were slower in response time and first fixation than were participants with TD. Participants with TD showed longer fixation on items with marginal (compared to central) levels of interest. The social-film experiment showed that participants with ASD were slower to orient their gazes towards the characters’ faces and looked at speaking characters for less time than did the group with TD. This result correlates with less use of mental verbs in their narratives and less time spent looking at marginal items in the CB experiment. Conclusions Results suggest reduced processing speed in young adults with ASD, which is associated with enhanced processing of local details. Clinically, these results imply that teaching strategies (e.g., cognitive cues) to process social context efficiently could benefit individuals with ASD.

WAGEMANS, Auteur Article en page(s) : p.728-739 Langues : Anglais (eng) Mots-clés : autism spectrum disorders change blindness local-global processing vision research Index. décimale : PER Périodiques Résumé : Previous research suggested that adolescents with autism spectrum disorder are better than typically developing children in detecting local, non-social details within complex visual scenes. To better understand these differences, we used the image database by Sareen et al., containing the size and on-screen location information of all changes in the images, in a change blindness paradigm. In this task, an original and a modified real-world scene, separated by a gray blank, alternate repeatedly until observers detect the change. Our results indicated that participants with and without autism spectrum disorder performed similarly when scenes were presented upright, but that only the performance of the typically developing adolescents became worse in the inverted scene condition. In this condition, the correlation between performance and both image difficulty and change predictability was significantly weaker in autism spectrum disorder than in typically developing participants. We suggest that these findings result from a more locally biased search strategy in people with autism spectrum disorder, compared to typically developing participants, in tasks in which the rapid processing of global information does not help to improve change detection performance. Finally, although we found change location, change size, and age to influence participant performance, none of these was directly linked to the observed group-level differences.

Children and adolescents relied more on social referencing cues in the scene as compared to adults, and in the presence of such cues, were less able to use other kinds of cues.

Twenty-two children diagnosed with ASD and 22 matched typically developing (TD) children were told to detect changes in objects of central interest or objects of marginal interest (MI) embedded in either emotion-laden (positive or negative) or neutral real-world pictures. The results showed that emotion-laden pictures equally interfered with performance of both ASD and TD children, slowing down reaction times compared with neutral pictures. Children with ASD were faster than TD children, particularly in detecting changes in MI objects, the most difficult condition. However, their performance was less accurate than performance of TD children just when the pictures were negative. These findings suggest that children with ASD have better visual search abilities than TD children only when the search is particularly difficult and requires strong serial search strategies. The emotional–social impairment that is usually considered as a typical feature of ASD seems to be limited to processing of negative emotional information.
