Developmental changes in attention to social information from childhood to adolescence in autism spectrum disorders: a comparative study / Toru FUJIOKA in Molecular Autism, 11 (2020)

Titre : Developmental changes in attention to social information from childhood to adolescence in autism spectrum disorders: a comparative study Type de document : Texte imprimé et/ou numérique Auteurs : Toru FUJIOKA, Auteur ; Kenji J. TSUCHIYA, Auteur ; Manabu SAITO, Auteur ; Yoshiyuki HIRANO, Auteur ; Muneaki MATSUO, Auteur ; Mitsuru KIKUCHI, Auteur ; Yoshihiro MAEGAKI, Auteur ; Damee CHOI, Auteur ; Sumi KATO, Auteur ; Tokiko YOSHIDA, Auteur ; Yuko YOSHIMURA, Auteur ; Sawako OOBA, Auteur ; Yoshifumi MIZUNO, Auteur ; Shinichiro TAKIGUCHI, Auteur ; Hideo MATSUZAKI, Auteur ; Akemi TOMODA, Auteur ; Katsuyuki SHUDO, Auteur ; Masaru NINOMIYA, Auteur ; Taiichi KATAYAMA, Auteur ; Hirotaka KOSAKA, Auteur Article en page(s) : 24 p. 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 : Sex-different abnormalities in the right second to fourth digit ratio in Japanese individuals with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Yasuhiro MASUYA, Auteur ; Yuko OKAMOTO, Auteur ; Keisuke INOHARA, Auteur ; Yukiko MATSUMURA, Auteur ; Toru FUJIOKA, Auteur ; Yuji WADA, Auteur ; Hirotaka KOSAKA, Auteur Article en page(s) : p.1-10 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The prevalence of autism spectrum disorders (ASDs) is higher in men than in women. The extreme male brain theory proposes that excessive prenatal testosterone activity could be a risk factor for ASDs. However, it is unclear whether prenatal sex hormone activity is a risk factor for women. The ratio of the length of the second to fourth digits (2D:4D) is considered to be a biomarker of the prenatal ratio of testosterone to estrogen. Therefore, this study compared the 2D:4D ratios of women with and without ASDs to determine if prenatal sex hormone activity could be a risk factor for ASDs in women.
