Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Developmental change Eye-tracking Social information Index. décimale : PER Périodiques Résumé : BACKGROUND: Elucidating developmental changes in the symptoms of autism spectrum disorder (ASD) is important to support individuals with ASD. However, no report has clarified the developmental changes in attention to social information for a broad age range. The aim of this study was to investigate the developmental changes in attention to social information from early childhood to adolescence in individuals with ASD and typically developed (TD) children. METHODS: We recruited children with ASD (n = 83) and TD participants (n = 307) between 2 and 18?years of age. Using the all-in-one-eye-tracking system, Gazefinder, we measured the percentage fixation time allocated to areas of interest (AoIs) depicted in movies (the eyes and mouth in movies of a human face with/without mouth motion, upright and inverted biological motion in movies showing these stimuli simultaneously, people and geometry in preference paradigm movies showing these stimuli simultaneously, and objects with/without finger-pointing in a movie showing a woman pointing toward an object). We conducted a three-way analysis of variance, 2 (diagnosis: ASD and TD) by 2 (sex: male and female) by 3 (age group: 0-5, 6-11, and 12-18 years) and locally weighted the scatterplot smoothing (LOESS) regression curve on each AoI. RESULTS: In the face stimuli, the percentage fixation time to the eye region for the TD group increased with age, whereas the one for the ASD group did not. In the ASD group, the LOESS curves of the gaze ratios at the eye region increased up to approximately 10?years of age and thereafter tended to decrease. For the percentage fixation time to the people region in the preference paradigm, the ASD group gazed more briefly at people than did the TD group. LIMITATIONS: It is possible that due to the cross-sectional design, the degree of severity and of social interest might have differed according to the subjects' age. CONCLUSIONS: There may be qualitative differences in abnormal eye contact in ASD between individuals in early childhood and those older than 10?years.

Titre : Sensory Processing Patterns and Fusiform Activity During Face Processing in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Ayaka KUNO-FUJITA, Auteur ; Toshiki IWABUCHI, Auteur ; Keisuke WAKUSAWA, Auteur ; Hiroyuki ITO, Auteur ; Katsuaki SUZUKI, Auteur ; Akira SHIGETOMI, Auteur ; Kosaka HIROTAKA, Auteur ; Masatsugu TSUJII, Auteur ; Kenji J. TSUCHIYA, Auteur Article en page(s) : p.741-750 Langues : Anglais (eng) Mots-clés : autism spectrum disorder fMRI face processing fusiform gyrus sensory processing sensory profile Index. décimale : PER Périodiques Résumé : A growing body of evidence has indicated that individuals with autism spectrum disorder (ASD) exhibit abnormal reactions to sensory stimuli and impaired face processing. Although behavioral studies have reported that individual differences in sensory processing patterns are correlated with performance in face processing tasks, the neural substrates underlying the association between sensory processing patterns and face processing remain unknown. Using functional magnetic resonance imaging, the present study examined the relationships between sensory processing patterns assessed with the Adolescent/Adult Sensory Profile (AASP) and brain activity during a one-back task with two types of stimuli (face or house pictures). We enrolled 18 Japanese adults with ASD and 19 age- and IQ-matched controls. Sensation Avoiding scores, which were assessed using the AASP, were positively correlated with right fusiform activity during the presentation of pictures of faces in the ASD group, but not in the control group. This suggests that abnormal sensory processing patterns in ASD are associated with abnormal face-related brain activity, possibly resulting in impaired face processing. Autism Res 2020, 13: 741-750. (c) 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Sensory abnormalities are one of the most common symptoms in people with autism spectrum disorder (ASD). This study shows that individuals with ASD who react abnormally to sensory stimuli also exhibit atypical brain activity when recognizing faces. Abnormal sensory processing may partly explain the difficulty that people diagnosed with ASD have in identifying others' faces.
