Titre : Development of emotion comprehension in children with autism spectrum disorder and Williams syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Yoko HAKUNO, Auteur ; Kosuke ASADA, Auteur ; Takahiro IKEDA, Auteur ; Takanori YAMAGATA, Auteur ; Masahiro HIRAI, Auteur Article en page(s) : p.2378-2390 Index. décimale : PER Périodiques Résumé : Abstract Although research has shed light on the development of emotion comprehension in typically developing children, little is known about emotion comprehension in children who are developing atypically. Thus, this study examined the developmental trajectory of emotion understanding in non-clinical (NC) children and children with autism spectrum disorder (ASD) and Williams syndrome (WS) using a Test of Emotion Comprehension. In the test, we measured children's understanding of (I) recognition of emotions based on facial expressions, (II) external causes of emotions, (III) desire-based emotions, (IV) belief-based emotions, (V) the influence of a reminder on a present emotional state, (VI) regulating an experienced emotion, (VII) hiding an emotional state, (VIII) mixed emotions, and (IX) moral emotions. A Bayesian modeling approach was applied to compare the developmental trajectories of emotion understanding across the syndrome groups. The results revealed that NC children and children with WS followed significantly different developmental trajectories in specific aspects of emotion understanding, while children with ASD followed a very similar path to NC children. Children with ASD and NC children gradually developed an understanding of each component of emotion comprehension as they matured. However, the understanding of some components, such as desire-based emotions, hiding an emotional state, and moral emotions, in children with WS was affected by their Autism Spectrum Quotient scores. This is one of the first cross-syndrome studies to assess the development of emotion comprehension in children with ASD and WS, providing important insights for understanding the nature of disability and advancing the development of intervention programs.

Titre : Developmental process of the understanding of linguistic register in children: A comparison of typically developing children, autistic children, and children with Williams syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Yoko HAKUNO, Auteur ; Kosuke ASADA, Auteur ; Takahiro IKEDA, Auteur ; Takanori YAMAGATA, Auteur ; Masahiro HIRAI, Auteur Article en page(s) : p.1902-1915 Langues : Anglais (eng) Mots-clés : autism cross-syndrome comparison linguistic register register selection Williams syndrome Index. décimale : PER Périodiques Résumé : Abstract Although the developmental process of linguistic register?the appropriate manner of speech as determined by the listener and social situation?has been gradually clarified in typically developing (TD) children, research on the mechanism and developmental process of register acquisition in atypically developing children are insufficient. This study compared the developmental process of understanding linguistic register among TD children, autistic children, and those with Williams syndrome (WS), and examined the contributions of social cognition and motivation to the acquisition of linguistic register. Two experiments were designed to assess the recognition of which linguistic register to use when communicating with different listeners and of the listener's feelings according to the speakers' use of register. The results revealed that the process of understanding register-listener associations was nearly identical among all groups of children and their understanding improved with age. Conversely, their understanding of the effect of register selection on the listener's feelings varied. Importantly, as TD children mature, they become aware that adult listeners may feel negatively when spoken to in an inappropriate register, whereas autistic children and those with WS do not exhibit the same awareness. Thus, our results suggest that atypical social cognition and motivation do not disturb the understanding of register-listener associations. However, social cognition and motivation play important roles in understanding the effect of register selection on the listener's feelings. These findings provide a significant contribution to clarifying the mechanism of linguistic register acquisition.

Titre : Differential electrophysiological responses to biological motion in children and adults with and without autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Masahiro HIRAI, Auteur ; Atsuko GUNJI, Auteur ; Yuki INOUE, Auteur ; Yosuke KITA, Auteur ; Takashi HAYASHI, Auteur ; Kengo NISHIMAKI, Auteur ; Miho NAKAMURA, Auteur ; Ryusuke KAKIGI, Auteur ; Masumi INAGAKI, Auteur Article en page(s) : p.1623-1634 Langues : Anglais (eng) Mots-clés : Point-light walker Biological motion Event-related potential (ERP) Autism spectrum disorder Development Children Index. décimale : PER Périodiques Résumé : Abstract Although atypical processing of biological motion (BM) in individuals with autism spectrum disorder (ASD) has been reported, the temporal profile of the neural response to BM is not well explored. In the current study, event-related potentials (ERPs) were measured in 12 individuals with ASD, aged 8–22 years, and 12 age- and gender-matched normal controls, to investigate the electrophysiological response to BM and a control visual stimulus. By introducing a novel experimental paradigm that can dissociate the electrophysiological responses to motion processing and the global shape processing of BM, we found that: (1) the timing of the response was preserved in ASD groups, whereas (2) the ERP response to BM was significantly enhanced compared with scrambled point-light motion (SM) in normal controls; the responses to both BM and SM were not significantly different in subjects with ASD. Because we did not find a significant group effect on the peak and mean amplitude induced by BM, it is presumed that this atypical response in individuals with ASD was due to over-sensitivity to the local motion signals. This experimental paradigm showed atypical local motion processing of BM in individuals with ASD.
