Microstructural Anomalies Evaluated by Neurite Orientation Dispersion and Density Imaging Are Related to Deficits in Facial Emotional Recognition via Perceptual-Binding Difficulties in Autism Spectrum Disorder / Fumihiko YASUNO in Autism Research, 13-5 (May 2020)

Titre : Microstructural Anomalies Evaluated by Neurite Orientation Dispersion and Density Imaging Are Related to Deficits in Facial Emotional Recognition via Perceptual-Binding Difficulties in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Fumihiko YASUNO, Auteur ; Manabu MAKINODAN, Auteur ; Masato TAKAHASHI, Auteur ; Kiwamu MATSUOKA, Auteur ; Hiroaki YOSHIKAWA, Auteur ; Soichiro KITAMURA, Auteur ; Rio ISHIDA, Auteur ; Naoko KISHIMOTO, Auteur ; Toshiteru MIYASAKA, Auteur ; Kimihiko KICHIKAWA, Auteur ; Toshifumi KISHIMOTO, Auteur Article en page(s) : p.729-740 Langues : Anglais (eng) Mots-clés : Noddi autism spectrum disorder corpus callosum facial emotional recognition interhemispheric neurite-orientation dispersion and density imaging perceptual integration Index. décimale : PER Périodiques Résumé : The integration of visual features is important for recognizing objects as a coherent whole, a key domain of difficulty in autism spectrum disorder (ASD). We tested the hypothesis that ASD patients exhibit difficulties in facial emotional recognition via perceptual binding difficulties due to weak coherence. We assessed 18 ASD and 27 typically developing individuals for their ability to identify emotional expressions from faces in pictures moving behind a narrow vertical and horizontal slit. In this task, only a single local piece of facial information was provided at any one time through the slit. Using a voxel-based analysis of neurite-orientation dispersion and density imaging (NODDI), we examined the relationship between NODDI index values at each voxel and the behavioral performance of ASD patients in the slit-viewing paradigm. ASD patients demonstrated impaired recognition of facial emotional expression only in horizontal slit-viewing. This deficit was associated with deficits in communication ability. Voxel-based analysis revealed significant negative correlations between behavioral deficits in horizontal slit-viewing and NODDI index values in clusters including the ventral occipital complex region, superior temporal/parietal association areas, and forceps major of the corpus callosum. Our results indicated deficits for the first time in perceptual integration of facial expression across hemispheres in ASD patients due to microstructural disturbances in the corpus callosum and areas related to viewing of the human face. This may underscore the difficulties faced by ASD patients in understanding the emotions of other people, contributing to impairments in communication ability in ASD patients. Autism Res 2020, 13: 729-740. (c) 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We assessed ASD and typically developing individuals for their ability to identify emotional expressions from faces in pictures moving behind a narrow vertical and horizontal slit. ASD patients demonstrated impaired recognition of facial emotional expression only in horizontal slit-viewing. Voxel-based analysis revealed significant negative correlations between behavioral deficits and NODDI index values in clusters including the corpus callosum. Our results indicated deficits in perceptual integration of facial expression across hemispheres in ASD patients potentially resulting from microstructural disturbances.

SOROOR, Auteur ; S. MOKHTARI, Auteur ; H. POURETEMAD, Auteur Article en page(s) : p.1019-1029 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Child Humans Motor Activity Autism spectrum disorders (ASD) Global processing strategy Illusory shape Perceptual integration Perceptual priming Index. décimale : PER Périodiques Résumé : We investigated (1) if the perceptual integration performance is different in children with ASD in comparison with their typically developed (TD) counterparts; and (2) if activating- priming- the global processing strategy, could benefit the integration performance of children with ASD in the subsequent task. We observed that in comparison with the TD group, children with ASD had lower performance in an information integration task that required identification of illusory shapes. Additionally, we observed that priming the global processing strategy increased the correct identification of the illusory shapes in the subsequent task. We suggested that studies on priming effect shed light on the different aspects of perceptual properties of ASD, and could also be used in developing new rehabilitation plans.
