Titre : Neural Correlates of Audiovisual Temporal Binding Window in Individuals With Schizotypal and Autistic Traits: Evidence From Resting-State Functional Connectivity Type de document : Texte imprimé et/ou numérique Auteurs : Han-Yu ZHOU, Auteur ; Yong-Ming WANG, Auteur ; Rui-Ting ZHANG, Auteur ; Eric F. C. CHEUNG, Auteur ; Christos PANTELIS, Auteur ; Raymond C. K. CHAN, Auteur Article en page(s) : p.668-680 Langues : Anglais (eng) Mots-clés : audiovisual autistic traits resting-state functional connectivity schizotypal traits temporal binding window Index. décimale : PER Périodiques Résumé : Temporal proximity is an important clue for multisensory integration. Previous evidence indicates that individuals with autism and schizophrenia are more likely to integrate multisensory inputs over a longer temporal binding window (TBW). However, whether such deficits in audiovisual temporal integration extend to subclinical populations with high schizotypal and autistic traits are unclear. Using audiovisual simultaneity judgment (SJ) tasks for nonspeech and speech stimuli, our results suggested that the width of the audiovisual TBW was not significantly correlated with self-reported schizotypal and autistic traits in a group of young adults. Functional magnetic resonance imaging (fMRI) resting-state activity was also acquired to explore the neural correlates underlying inter-individual variability of TBW width. Across the entire sample, stronger resting-state functional connectivity (rsFC) between the left superior temporal cortex and the left precuneus, and weaker rsFC between the left cerebellum and the right dorsal lateral prefrontal cortex were correlated with a narrower TBW for speech stimuli. Meanwhile, stronger rsFC between the left anterior superior temporal gyrus and the right inferior temporal gyrus was correlated with a wider audiovisual TBW for non-speech stimuli. The TBW-related rsFC was not affected by levels of subclinical traits. In conclusion, this study indicates that audiovisual temporal processing may not be affected by autistic and schizotypal traits and rsFC between brain regions responding to multisensory information and timing may account for the inter-individual difference in TBW width. LAY SUMMARY: Individuals with ASD and schizophrenia are more likely to perceive asynchronous auditory and visual events as occurring simultaneously even if they are well separated in time. We investigated whether similar difficulties in audiovisual temporal processing were present in subclinical populations with high autistic and schizotypal traits. We found that the ability to detect audiovisual asynchrony was not affected by different levels of autistic and schizotypal traits. We also found that connectivity of some brain regions engaging in multisensory and timing tasks might explain an individual's tendency to bind multisensory information within a wide or narrow time window.

Titre : Audiovisual temporal integration and rapid temporal recalibration in adolescents and adults: Age-related changes and its correlation with autistic traits Type de document : Texte imprimé et/ou numérique Auteurs : Han-Yu ZHOU, Auteur ; Li-Juan SHI, Auteur ; Han-Xue YANG, Auteur ; Eric F. C. CHEUNG, Auteur ; Raymond C. K. CHAN, Auteur Article en page(s) : p.615-626 Langues : Anglais (eng) Mots-clés : adolescents age effect audiovisual integration autistic traits rapid temporal recalibration temporal binding window Index. décimale : PER Périodiques Résumé : Temporal structure is a key factor in determining the relatedness of multisensory stimuli. Stimuli that are close in time are more likely to be integrated into a unified perceptual representation. To investigate the age-related developmental differences in audiovisual temporal integration and rapid temporal recalibration, we administered simultaneity judgment (SJ) tasks to a group of adolescents (11-14 years) and young adults (18-28 years). No age-related changes were found in the width of the temporal binding window within which participants are highly likely to combine multisensory stimuli. The main distinction between adolescents and adults was audiovisual temporal recalibration. Although participants of both age groups could rapidly recalibrate based on the previous trial for speech stimuli (i.e., syllable utterances), only adults but not adolescents showed short-term recalibration for simple and non-speech stimuli. In both adolescents and adults, no significant correlation was found between audiovisual temporal integration ability and autistic or schizotypal traits. These findings provide new information on the developmental trajectory of basic multisensory function and may have implications for neurodevelopmental disorders (e.g., autism) with altered audiovisual temporal integration. Autism Res 2020, 13: 615-626. (c) 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: Utilizing temporal cues to integrate and separate audiovisual information is a fundamental ability underlying higher order social communicative functions. This study examines the developmental changes of the ability to detect audiovisual asynchrony and rapidly adjust sensory decisions based on previous sensory input. In healthy adolescents and young adults, the correlation between autistic traits and audiovisual integration ability failed to reach a significant level. Therefore, more research is needed to examine whether impairment in basic sensory functions is correlated with broader autism phenotype in nonclinical populations. These results may help us understand altered multisensory integration in people with autism.
