Audiovisual Speech Perception in Children with Autism Spectrum Disorders: Evidence from Visual Phonemic Restoration / J. IRWIN in Journal of Autism and Developmental Disorders, 52-1 (January 2022)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 52-1 (January 2022) . - p.28-37 Titre : Audiovisual Speech Perception in Children with Autism Spectrum Disorders: Evidence from Visual Phonemic Restoration Type de document : Texte imprimé et/ou numérique Auteurs : J. IRWIN, Auteur ; T. AVERY, Auteur ; D. KLEINMAN, Auteur ; N. LANDI, Auteur Article en page(s) : p.28-37 Langues : Anglais (eng) Mots-clés : Auditory Perception  Autism Spectrum Disorder  Child  Cues  Evoked Potentials  Humans  Speech  Speech Perception  Visual Perception  Audiovisual  Autism  Phonemic restoration Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorders have been reported to be less influenced by a speaker's face during speech perception than those with typically development. To more closely examine these reported differences, a novel visual phonemic restoration paradigm was used to assess neural signatures (event-related potentials [ERPs]) of audiovisual processing in typically developing children and in children with autism spectrum disorder. Video of a speaker saying the syllable /ba/ was paired with (1) a synthesized /ba/ or (2) a synthesized syllable derived from /ba/ in which auditory cues for the consonant were substantially weakened, thereby sounding more like /a/. The auditory stimuli are easily discriminable; however, in the context of a visual /ba/, the auditory /a/ is typically perceived as /ba/, producing a visual phonemic restoration. Only children with ASD showed a large /ba/-/a/ discrimination response in the presence of a speaker producing /ba/, suggesting reduced influence of visual speech.

TROIANI, Auteur Article en page(s) : p.5086-5099 Langues : Anglais (eng) Mots-clés : Attention  Autism  Eye tracking  Pupillometry  Visual perception Index. décimale : PER Périodiques Résumé : We assessed the association between dynamic changes in pupil response in the context of visual perception and quantitative measures of the autism phenotype in healthy adults. Using Navon stimuli in a task-switching paradigm, participants were instructed to identify global or local information based on a cue. Multiple pupil response trajectories across conditions were identified. We combined trajectory patterns for global and local conditions and used data-driven methods to identify three distinct pupil trajectory sub-groups. We report higher scores on quantitative measures of autism features in individuals who demonstrated an increased change in pupil diameter across both conditions. Results demonstrate the use of individualized pupil response trajectories in order to quantitatively characterize visual perception associated with the broader autism phenotype (BAP).

Motor skills, visual perception, and visual-motor integration in children and youth with Autism Spectrum Disorder / Leila FABER in Research in Autism Spectrum Disorders, 96 (August 2022)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 96 (August 2022) . - 101998 Titre : Motor skills, visual perception, and visual-motor integration in children and youth with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Leila FABER, Auteur ; Nellie VAN DEN BOS, Auteur ; Suzanne HOUWEN, Auteur ; Marina M. SCHOEMAKER, Auteur ; Sara ROSENBLUM, Auteur Article en page(s) : 101998 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder  Motor skills  Visual perception  Visual-motor integration Index. décimale : PER Périodiques Résumé : Background Motor skill deficits are prevalent among children with Autism Spectrum Disorder (ASD) however, little is known about the underlying mechanism of these deficits. In response to this gap, this study investigated how visual perception (VP) and visual-motor integration (VMI) are associated with motor skills among children and youth with ASD. Methods Sixty-seven individuals with ASD and sixty-seven age- and gender-matched individuals without ASD (age range: 9.83?15.13 years) participated. Motor skills were assessed with the Movement Assessment Battery for Children-2 (MABC-2) and VP and VMI with the respective components of the Beery-Buktenica Developmental Test of Visual-Motor Integration-6 (Beery VMI-6). Results Significantly more children and youth with ASD were in the red and orange zone of the MABC-2 traffic-lighting system for the total MABC-2 and the Aiming and Catching and Balance components compared to the children and youth without ASD. Both groups did not differ on the VP and VMI components of the Beery VMI-6. Pearson correlations between VP and VMI, and motor skills were weak but significant for the individuals without ASD, but not for the ASD group. Conclusion The current study added to the evidence about motor skill deficits among children and youth with ASD. VP and VMI were not related to motor skills, suggesting that these functions ? as measured in the current study ? are no underlying mechanisms of motor skill deficits of children with ASD and average intelligence. Diagnostic implications are provided for the evidence of motor skill deficits among children and youth with ASD.

Relationship Between the Performance of Self-Care and Visual Perception Among Young Children With Autism Spectrum Disorder and Typical Developing Children / I-Jou CHI in Autism Research, 14-2 (February 2021)  

Public ISBD [article]  inAutism Research > 14-2 (February 2021) . - p.315-323 Titre : Relationship Between the Performance of Self-Care and Visual Perception Among Young Children With Autism Spectrum Disorder and Typical Developing Children Type de document : Texte imprimé et/ou numérique Auteurs : I-Jou CHI, Auteur ; Ling-Yi LIN, Auteur Article en page(s) : p.315-323 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  self-care  visual perception  visual-motor integration  young child Index. décimale : PER Périodiques Résumé : Studies investigating the performance of self-care and visual perception in young children with autism spectrum disorder (ASD) are limited. The relationship between self-care performance and visual perception ability in young children with ASD is not yet clearly understood. Here, self-care performance was evaluated by the caregivers and therapists of children with ASD. The differences in self-care performance and visual perception ability were investigated in 66 children with ASD and 66 typically developing (TD) children between the ages of 48-83?months. The relationships between self-care and visual perception were tested in both two groups. The Assessment of Motor and Process Skills (AMPS) and the Chinese version of the Pediatric Evaluation of Disability Inventory (PEDI-C) were used to assess the children's self-care performance. The Test of Visual Perceptual Skills-Third Edition (TVPS-3) and the Developmental Test of Visual Perception-Third Edition (DTVP-3) were used to evaluate visual perception ability. Young children with ASD obtained significantly lower scores for self-care performance (AMPS and PEDI-C) and visual perception ability (TVPS-3 and DTVP) compared with TD children. Additionally, positive correlations were found between self-care performance and visual perception ability in young children with ASD. The results provide a valuable contribution to our understanding about self-care and visual perception performance of young children with ASD. The findings of this research highlight the need for pediatric practitioners to include self-care and visual-motor integration evaluations for young children with ASD. LAY SUMMARY: Young children with ASD obtained significantly lower scores for self-care performance and visual perception ability compared with TD children. Positive correlations were found between self-care performance and visual perception ability in young children with ASD. The results provide a valuable contribution to our understanding about self-care and visual perception performance of young children with ASD.

The Broader Autism Phenotype and Visual Perception in Children / Antoinette SABATINO-DICRISCIO in Journal of Autism and Developmental Disorders, 48-8 (August 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-8 (August 2018) . - p.2809-2820 Titre : The Broader Autism Phenotype and Visual Perception in Children Type de document : Texte imprimé et/ou numérique Auteurs : Antoinette SABATINO-DICRISCIO, Auteur ; V. TROIANI, Auteur Article en page(s) : p.2809-2820 Langues : Anglais (eng) Mots-clés : Broader autism phenotype  Children  Global-local processing  Tvps  Visual perception Index. décimale : PER Périodiques Résumé : Atypical visual perception has increasingly been described in individuals with autism spectrum disorders (ASD) and linked to quantitative, autism-like features that are present in children and adults without ASD. We investigated whether individual differences in visual processing skills were related to quantitative measures of autism traits in a pediatric sample with a range of clinical features. Visual processing was comprehensively characterized using the test of visual perceptual skills (TVPS), a standardized test of visual perception with seven subtests that capture a range of visual processing abilities. The TVPS Figure Ground (TVPS-FG) subtest requires an individual to disembed a smaller figure from a larger scene. TVPS-FG subtest scores were positively correlated with children's autism features as measured by a parental report of the Broader Autism Phenotype Questionnaire (BAP-Q). The correlation with BAP-Q was specific to the TVPS-FG subtest, as the other TVPS subtest scores were not significantly related to the BAP-Q. This adds to the growing body of research documenting that atypical visual processing is associated with the autism phenotype and highlights the importance of capturing quantitative traits in heterogeneous developmental brain disorders.
