Higher Tactile Temporal Resolution as a Basis of Hypersensitivity in Individuals with Autism Spectrum Disorder / Masayuki IDE in Journal of Autism and Developmental Disorders, 49-1 (January 2019)

Several studies have shown high individual variations in temporal processing of tactile stimuli. We hypothesized that these individual differences are linked to differences in hyper-reactivity among individuals with ASD. Participants performed two tasks as to vibrotactile stimuli: One is a temporal order judgement task, and another is a detection task. We found that individuals with ASD with higher temporal resolution tended to have more severe hypersensitivity symptoms. In contrast, the tactile detection threshold/sensitivity were related to the severities of stereotyped behaviour and restricted interests, rather than to hypersensitivity. Our findings demonstrate that higher temporal resolution to sensory stimuli may contribute to sensory hypersensitivity in individuals with ASD.

Joint attention and intelligence in children with autism spectrum disorder without severe intellectual disability / Misako SANO in Autism Research, 14-12 (December 2021)  

Public ISBD [article]  inAutism Research > 14-12 (December 2021) . - p.2603-2612 Titre : Joint attention and intelligence in children with autism spectrum disorder without severe intellectual disability Type de document : texte imprimé Auteurs : Misako SANO, Auteur ; Yuko YOSHIMURA, Auteur ; Tetsu HIROSAWA, Auteur ; Chiaki HASEGAWA, Auteur ; Kyung-Min AN, Auteur ; Sanae TANAKA, Auteur ; Nobushige NAITOU, Auteur ; Mitsuru KIKUCHI, Auteur Article en page(s) : p.2603-2612 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder/complications  Child  Child, Preschool  Cognition  Early Intervention, Educational  Humans  Intellectual Disability/complications  Intelligence  Kaufman Assessment Battery (K-ABC)  autism  autism diagnostic observation schedule  children  intelligence  joint attention Index. décimale : PER Périodiques Résumé : In children with autism spectrum disorder (ASD), joint attention is regarded as a predictor of language function, social skills, communication, adaptive function, and intelligence. However, existing information about the association between joint attention and intelligence is limited. Most such studies have examined children with low intelligence. For this study, we investigated whether joint attention is related to intelligence in young children with autism spectrum disorder (ASD) without severe intellectual disability. We analyzed 113 children with ASD aged 40-98 months. Their Kaufman Assessment Battery (K-ABC) Mental Processing Index (MPI) scores are 60 and more (mean 93.4). We evaluated their intelligence using K-ABC and evaluated their joint attention using ADOS-2. After we performed simple regression analyses using K-ABC MPI and its nine subscales as dependent variables, using joint attention as the independent variable, we identified joint attention as a positive predictor of the MPI and its two subscales. From this result, we conclude that joint attention is related to intelligence in young children with ASD without severe intellectual disability. This result suggests a beneficial effect of early intervention targeting joint attention for children with ASD. LAY SUMMARY: Joint attention is the ability to coordinate visual attention with another person and then shift one's gaze toward an object or event. Impairment of joint attention is regarded as an early marker of autism spectrum disorder (ASD). This study revealed impairment of joint attention as associated with lower intelligence in ASD children. These results are expected to constitute a rationale for future studies, particularly addressing beneficial effects of early intervention targeting joint attention for children with ASD.

Weakened Bayesian Calibration for Tactile Temporal Order Judgment in Individuals with Higher Autistic Traits / Makoto WADA in Journal of Autism and Developmental Disorders, 53-1 (January 2023)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 53-1 (January 2023) . - p.378-389 Titre : Weakened Bayesian Calibration for Tactile Temporal Order Judgment in Individuals with Higher Autistic Traits Type de document : texte imprimé Auteurs : Makoto WADA, Auteur ; Yumi UMESAWA, Auteur ; Misako SANO, Auteur ; Seiki TAJIMA, Auteur ; Shinichiro KUMAGAYA, Auteur ; Makoto MIYAZAKI, Auteur Article en page(s) : p.378-389 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Previous psychophysical studies reported a positive aftereffect in tactile temporal order judgments, which can be explained by the Bayesian estimation model ( ËœBayesian calibration’). We investigated the relationship between Bayesian calibration and autistic traits in participants with typical development (TD) and autism spectrum disorder (ASD). Bayesian calibration was weakened in TD participants with high autistic traits, consistent with the Ëœhypo-priors’ hypothesis for autistic perceptions. The results from the ASD group were generally observed as a continuation of those from the TD groups. Meanwhile, two ASD participants showed irregularly large positive or negative aftereffects. We discussed the mechanisms behind the general results among TD and ASD participants and two particular results among ASD participants based on the Bayesian estimation model.
