Abnormal Gait Patterns in Autism Spectrum Disorder and Their Correlations with Social Impairments / Linlin GONG in Autism Research, 13-7 (July 2020)  

Public ISBD [article]  inAutism Research > 13-7 (July 2020) . - p.1215-1226 Titre : Abnormal Gait Patterns in Autism Spectrum Disorder and Their Correlations with Social Impairments Type de document : Texte imprimé et/ou numérique Auteurs : Linlin GONG, Auteur ; Yajie LIU, Auteur ; Li YI, Auteur ; Jing FANG, Auteur ; Yisheng YANG, Auteur ; Kunlin WEI, Auteur Article en page(s) : p.1215-1226 Langues : Anglais (eng) Mots-clés : autism  gait  motor coordination  motor deficits  social impairments Index. décimale : PER Périodiques Résumé : Ground walking in humans is typically stable, symmetrical, characterized by smooth heel-to-toe ground contact. Previous studies on children with autism spectrum disorder (ASD) identified various gait abnormalities. However, they produced inconsistent findings, particularly for the occurrence of toe walking and gait symmetry between feet, owing to their reliance on retrospective reports, visual analysis of videos, or kinematic analysis of the gait. The present study examined gait functions in children with ASD using plantar pressure that quantified foot-ground interaction with high spatial and temporal resolutions. Fifty-eight 4-6-year-old children with ASD (12 low-functioning and 46 high-functioning autism) and 28 age-matched typically developed children walked straight 6 m at their preferred speed for 10 repetitions. We found that both ASD groups walked with more flat-footed contact pattern, more left-right asymmetry, and larger step-to-step variability than their controls. Furthermore, these abnormal gait characteristics were related to social impairments measured by the Autism Spectrum Quotient and Social Responsive Scale, supporting a close association between impaired motor coordination and core symptoms of autism. Autism Res 2020, 13: 1215-1226. © 2020 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We examined gait functions among children with autism by measuring their foot plantar pressure during simple straight walking. Children with ASD walked with a characteristic foot-ground contact pattern with inappropriate contact forces and large step-to-step variability when compared with their age-matched controls. These walking abnormalities were dependent on their social impairments but independent from their intelligence, indicating a close relationship between atypical motor coordination and core symptoms of autism.

Actions Speak Louder Than Words: The Role of Action in Self-Referential Advantage in Children With Autism / Gaowa WUYUN in Autism Research, 13-5 (May 2020)  

Public ISBD [article]  inAutism Research > 13-5 (May 2020) . - p.810-820 Titre : Actions Speak Louder Than Words: The Role of Action in Self-Referential Advantage in Children With Autism Type de document : Texte imprimé et/ou numérique Auteurs : Gaowa WUYUN, Auteur ; Jiao WANG, Auteur ; Long ZHANG, Auteur ; Kai WANG, Auteur ; Li YI, Auteur ; Yanhong WU, Auteur Article en page(s) : p.810-820 Langues : Anglais (eng) Mots-clés : action  autism spectrum disorder  ownership  self  self-referential advantage Index. décimale : PER Périodiques Résumé : Impaired self-processing in children with autism spectrum disorder (ASD) is believed to be closely associated with social-communicative deficits, a core symptom of ASD. In three experiments, we aimed to investigate (a) whether children with ASD exhibited deficient in self-processing, as reflected by their superior memory for self-related items as compared to other-related items, and (b) the role that action played in promoting self-processing in ASD. In Experiment 1, children with ASD, children with intellectual disability (ID), and typically developing children were asked to memorize items on the cards assigned to them or to the experimenter. The results indicated that the TD and ID groups had a self-referential memory advantage, but the ASD group did not. Experiments 2 and 3 examined whether the deficit in self-processing among children with ASDs was ameliorated when participants performed or observed an action to indicate the ownership of the items. We found that when children with ASD performed self-generated actions or observed virtual actions, they displayed a similar self-referential memory advantage as the other two groups. Our findings reveal that action plays an important role in the self-processing in children with ASD, and thereby contribute to a more comprehensive understanding of self-processing deficits in this population.

Activation of Thematic and Taxonomic Relations During Lexical-Semantic Processing in Autistic Children: Evidence From Eye Movements / Tianbi LI ; Ruoxi SHI ; Ran WEI ; Li YI in Autism Research, 18-5 (May 2025)  

Public ISBD [article]  inAutism Research > 18-5 (May 2025) . - p.1037-1049 Titre : Activation of Thematic and Taxonomic Relations During Lexical-Semantic Processing in Autistic Children: Evidence From Eye Movements Type de document : Texte imprimé et/ou numérique Auteurs : Tianbi LI, Auteur ; Ruoxi SHI, Auteur ; Ran WEI, Auteur ; Li YI, Auteur Article en page(s) : p.1037-1049 Langues : Anglais (eng) Mots-clés : autism  children  eye tracking  lexical-semantic network  lexical-semantic processing  taxonomic relations  thematic relations Index. décimale : PER Périodiques Résumé : ABSTRACT This study investigated the activation of thematic and taxonomic relations during online lexical-semantic processing in autistic children using an eye-tracking competition task. Thirty-six preschool-aged autistic children and 35 age-, gender-, and verbal-IQ-matched neurotypical (NT) children viewed arrays containing a target object, a thematically related competitor, a taxonomically related competitor, and an unrelated distractor while hearing the target word. Results revealed three key findings. First, both groups demonstrated activation of thematic and taxonomic relations during lexical processing, with comparable timing of activation onset. Second, while autistic children began to systematically orient attention to the target as quickly as NT children, they showed reduced overall attention to the target during lexical processing. Third, autistic children exhibited stronger activation of taxonomic relations and stronger taxonomic competition effects on target recognition compared to NT children, whereas their activation of thematic relations and thematic competition effects were comparable to NT children. These findings suggest that while the basic thematic and taxonomic activation processes remain robust in autistic children, and while their initial activation of the target and semantically related representations is as fast as that of NT children, the increased sensitivity to taxonomic relations in autistic children might interfere with the overall processing efficiency of target words. These results advance our understanding of lexical-semantic organization and processing in autism and provide implications for language intervention strategies.

Atypical understanding of mental terms in Chinese-speaking children with autism spectrum disorder / Li YI in Research in Autism Spectrum Disorders, 7-11 (November 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-11 (November 2013) . - p.1411-1417 Titre : Atypical understanding of mental terms in Chinese-speaking children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Li YI, Auteur ; Yuebo FAN, Auteur ; Jing ZHAO, Auteur ; Dan HUANG, Auteur ; Yunyi LI, Auteur ; Xiaobing ZOU, Auteur Article en page(s) : p.1411-1417 Langues : Anglais (eng) Mots-clés : Mental terms  Verb factivity  Theory of mind  Autism spectrum disorder  Chinese Index. décimale : PER Périodiques Résumé : Abstract The present study investigated how Chinese children with autism spectrum disorder (ASD) understand mental terms, especially their knowledge of verb factivity. We examined these children's ability to understand mental terms representing true belief (i.e., zhi1dao4, know) and false belief (i.e., yi3wei2, thought) and compared their ability with that of typically developing (TD) children matched with age, and TD children matched with verbal mental age (VMA). Children were asked to participate in a game to find a toy according to the experimenter's testimony, which involved these mental terms. Results showed that all children from these three groups understood zhi1dao4 better than yi3wei2. Particularly, children with ASD performed statistically significantly worse in understanding mental terms than their age-matched TD children, but not differently from VMA-matched TD children. The understanding of mental verbs was correlated with the language ability of children with ASD, and with age, language ability and executive function of TD children. After controlling for the effects of age, general language ability, and executive functions, the group difference of mental verb understanding still existed.

Autistic children?s visual sensitivity to face movement / Qiandong WANG in Development and Psychopathology, 36-4 (October 2024)  

Public ISBD [article]  inDevelopment and Psychopathology > 36-4 (October 2024) . - p.1616-1625 Titre : Autistic children?s visual sensitivity to face movement Type de document : Texte imprimé et/ou numérique Auteurs : Qiandong WANG, Auteur ; Xue LI, Auteur ; Xiaoyun GONG, Auteur ; Tingni YIN, Auteur ; Qinyi LIU, Auteur ; Li YI, Auteur ; Jing LIU, Auteur Article en page(s) : p.1616-1625 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  biological motion  development  eye-tracking  face movement Index. décimale : PER Périodiques Résumé : There is a pressing need for studies of large sample sizes and variable age ranges to delineate the mechanism underlying reduced visual attention to biological motion in autism. Here we focused on the basic movement of the eyes or mouth in guiding attention. The stimuli face blinked continuously or moved the mouth silently. In a large sample (145 autistic and 132 non-autistic participants) ranging from 3 to 17 years old, we assessed whether autistic participants showed reduced visual attention to basic movement of the eyes or mouth using a free-viewing eye-tracking task. We found that, like non-autistic participants, autistic participants increased their eye-looking time when viewing the blinking face and increased mouth-looking time when viewing the mouth-moving face. Furthermore, these effects were stable across ages, suggesting the presence of a developmentally stable attentional capture by basic face movements in both groups. We also found that autistic participants looked less at basic face movement than non-autistic participants. Our results suggest that autistic children and adolescents could modulate their visual attention to the basic face movements, but their modulation effect is weaker than non-autistic participants. These results further our understanding of the mechanism underlying visual attention-to-face movement in autistic people.
