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 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.

Childhood high-frequency EEG activity during sleep is associated with incident insomnia symptoms in adolescence / Julio FERNANDEZ-MENDOZA in Journal of Child Psychology and Psychiatry, 60-7 (July 2019)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 60-7 (July 2019) . - p.742-751 Titre : Childhood high-frequency EEG activity during sleep is associated with incident insomnia symptoms in adolescence Type de document : texte imprimé Auteurs : Julio FERNANDEZ-MENDOZA, Auteur ; Yun LI, Auteur ; Jing FANG, Auteur ; Susan L. CALHOUN, Auteur ; Alexandros N. VGONTZAS, Auteur ; Duanping LIAO, Auteur ; Edward O BIXLER, Auteur Année de publication : 2019 Article en page(s) : p.742-751 Langues : Anglais (eng) Mots-clés : adolescence  beta  childhood  electroencephalogram  hyperarousal  incidence  insomnia symptoms Index. décimale : PER Périodiques Résumé : BACKGROUND: Insomnia has been associated in cross-sectional studies with increased beta (15-35 Hz) electroencephalogram (EEG) power during nonrapid eye movement (NREM) sleep, an index of cortical hyperarousal. However, it is unknown whether this cortical hyperarousal is present before individuals with insomnia develop the disorder. To fill this gap, we examined the association of childhood sleep high-frequency EEG activity with incident insomnia symptoms (i.e., absence of insomnia symptoms in childhood but presence in adolescence). METHODS: We studied a case-control subsample of 45 children (6-11 years) from the Penn State Child Cohort, a population-based random sample of 421 children, who were followed up after 8 years as adolescents (13-20 years). We examined low-beta (15-25 Hz) and high-beta (25-35 Hz) relative power at central EEG derivations during NREM sleep and, in secondary analyses, during sleep onset latency, sleep onset, and REM sleep. Incident insomnia symptoms were defined as the absence of parent-reported difficulty falling and/or staying asleep during childhood and a self-report of these insomnia symptoms during adolescence. RESULTS: Childhood high-beta power during NREM sleep was significantly increased in children who developed insomnia symptoms in adolescence (n = 25) as compared to normal sleeping controls (n = 20; p = .03). Multivariable-adjusted logistic regression models showed that increased childhood high-beta EEG power during NREM sleep was associated with a threefold increased odds (95% CI = 1.12-7.98) of incident insomnia symptoms in adolescence. No other significant relationships were observed for other sleep/wake states or EEG frequency bands. CONCLUSIONS: Increased childhood high-frequency EEG power during NREM sleep is associated with incident insomnia symptoms in adolescence. This study indicates that cortical hyperarousal during sleep may be a premorbid neurophysiological sign of insomnia, which may mediate the increased risk of psychiatric disorders associated with insomnia.

Face-viewing patterns predict audiovisual speech integration in autistic children / Shuyuan FENG in Autism Research, 14-12 (December 2021)  

Public ISBD [article]  inAutism Research > 14-12 (December 2021) . - p.2592-2602 Titre : Face-viewing patterns predict audiovisual speech integration in autistic children Type de document : texte imprimé Auteurs : Shuyuan FENG, Auteur ; Haoyang LU, Auteur ; Quan WANG, Auteur ; Tianbi LI, Auteur ; Jing FANG, Auteur ; Lihan CHEN, Auteur ; Li YI, Auteur Année de publication : 2021 Article en page(s) : p.2592-2602 Langues : Anglais (eng) Mots-clés : Acoustic Stimulation  Autism Spectrum Disorder/complications  Autistic Disorder/complications  Child  Child, Preschool  Female  Humans  Mouth  Speech  Speech Perception  Visual Perception  McGurk effect  atypical face-viewing patterns  audiovisual speech integration  autistic children  eye movements Index. décimale : PER Périodiques Résumé : Autistic children show audiovisual speech integration deficits, though the underlying mechanisms remain unclear. The present study examined how audiovisual speech integration deficits in autistic children could be affected by their looking patterns. We measured audiovisual speech integration in 26 autistic children and 26 typically developing (TD) children (4- to 7-year-old) employing the McGurk task (a videotaped speaker uttering phonemes with her eyes open or closed) and tracked their eye movements. We found that, compared with TD children, autistic children showed weaker audiovisual speech integration (i.e., the McGurk effect) in the open-eyes condition and similar audiovisual speech integration in the closed-eyes condition. Autistic children viewed the speaker's mouth less in non-McGurk trials than in McGurk trials in both conditions. Importantly, autistic children's weaker audiovisual speech integration could be predicted by their reduced mouth-looking time. The present study indicated that atypical face-viewing patterns could serve as one of the cognitive mechanisms of audiovisual speech integration deficits in autistic children. LAY SUMMARY: McGurk effect occurs when the visual part of a phoneme (e.g., "ga") and the auditory part of another phoneme (e.g., "ba") uttered by a speaker were integrated into a fused perception (e.g., "da"). The present study examined how McGurk effect in autistic children could be affected by their looking patterns for the speaker's face. We found that less looking time for the speaker's mouth in autistic children could predict weaker McGurk effect. As McGurk effect manifests audiovisual speech integration, our findings imply that we could improve audiovisual speech integration in autistic children by directing them to look at the speaker's mouth in future intervention.

Twenty-eight 4- to 7-year-old children with ASD and 28 age- and IQ-matched typically developing (TD) peers learned the distrusting and deceptive rules in a non-social condition, in which they were playing with a computer, or a social condition with another person pretending to interact via a computer. Results showed intact rule-learning ability in the ASDs in the non-social condition, but poorer overall performance and slower learning process than TD children when they thought that they interacted with a human opponent. Rule learning in ASD was affected by their beliefs about the social context.

Trust and Deception in Children with Autism Spectrum Disorders: A Social Learning Perspective / Yiying YANG in Journal of Autism and Developmental Disorders, 47-3 (March 2017)

We tested 42 high-functioning children with ASD and 38 age- and ability-matched typically developing (TD) children in trust and deception tasks and a novel condition with reduced social components. Results indicated that while TD children improved their performance with more social components, children with ASD lacked this additional performance gain, though they performed similarly as TD children in the condition with reduced social components. Our findings highlight that deficits of ASD in trust and deception are primarily associated with failure of use of social cues.
