Audiovisual integration and the P2 component in adult Asperger’s syndrome: An ERP-study / Anna BORGOLTE in Research in Autism Spectrum Disorders, 84 (June 2021)
[article]
Titre : Audiovisual integration and the P2 component in adult Asperger’s syndrome: An ERP-study Type de document : Texte imprimé et/ou numérique Auteurs : Anna BORGOLTE, Auteur ; Mandy ROY, Auteur ; Christopher SINKE, Auteur ; Stefan BLEICH, Auteur ; Thomas F. MÜNTE, Auteur ; Gregor R. SZYCIK, Auteur Article en page(s) : 101787 Langues : Anglais (eng) Mots-clés : Asperger’s syndrome Autism Audiovisual integration Double flash illusion EEG P2 Index. décimale : PER Périodiques Résumé : Background A widened temporal window of integration (TWI) in audiovisual processing has been detected for children with autism spectrum disorder. However, research indicates a narrowing of this TWI and an associated change in audiovisual integration in the course of development. Methods To further elucidate audiovisual integration processes in adulthood, we compared adult participants with Asperger’s Syndrome (AS) to healthy controls (HC) by using the sound-induced double flash illusion. For a better understanding of underlying neural mechanisms, event-related potentials were measured via electroencephalography (EEG). Results The number of reported sound-induced flash illusions indicated audiovisual integration. A similar TWI size for both, participants with AS and HC, was found. Additionally, enhanced P2 amplitudes were detected for participants with AS compared to HC. Conclusion Results indicate an involvement of attentional processes in audiovisual perception in participants with AS.

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.

Titre : A Comparison of the Development of Audiovisual Integration in Children with Autism Spectrum Disorders and Typically Developing Children Type de document : Texte imprimé et/ou numérique Auteurs : Natalie TAYLOR, Auteur ; Claire ISAAC, Auteur ; Elizabeth MILNE, Auteur Année de publication : 2010 Article en page(s) : p.1403-1411 Langues : Anglais (eng) Mots-clés : Autism Spectrum Disorder Audiovisual integration Development Index. décimale : PER Périodiques Résumé : This study aimed to investigate the development of audiovisual integration in children with Autism Spectrum Disorder (ASD). Audiovisual integration was measured using the McGurk effect in children with ASD aged 7–16 years and typically developing children (control group) matched approximately for age, sex, nonverbal ability and verbal ability. Results showed that the children with ASD were delayed in visual accuracy and audiovisual integration compared to the control group. However, in the audiovisual integration measure, children with ASD appeared to ‘catch-up’ with their typically developing peers at the older age ranges. The suggestion that children with ASD show a deficit in audiovisual integration which diminishes with age has clinical implications for those assessing and treating these children.

Titre : Temporal synchrony and audiovisual integration of speech and object stimuli in autism Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth SMITH, Auteur ; Shouling ZHANG, Auteur ; Loisa BENNETTO, Auteur Article en page(s) : p.11-19 Langues : Anglais (eng) Mots-clés : Speech processing Audiovisual integration Temporal perception Index. décimale : PER Périodiques Résumé : AbstractBackground Individuals with Autism Spectrum Disorders (ASD) have been shown to have multisensory integration deficits, which may lead to problems perceiving complex, multisensory environments. For example, understanding audiovisual speech requires integration of visual information from the lips and face with auditory information from the voice, and audiovisual speech integration deficits can lead to impaired understanding and comprehension. While there is strong evidence for an audiovisual speech integration impairment in ASD, it is unclear whether this impairment is due to low level perceptual processes that affect all types of audiovisual integration or if it is specific to speech processing. Method Here, we measure audiovisual integration of basic speech (i.e., consonant-vowel utterances) and object stimuli (i.e., a bouncing ball) in adolescents with ASD and well-matched controls. We calculate a temporal window of integration (TWI) using each individual’s ability to identify which of two videos (one temporally aligned and one misaligned) matches auditory stimuli. The TWI measures tolerance for temporal asynchrony between the auditory and visual streams, and is an important feature of audiovisual perception. Results While controls showed similar tolerance of asynchrony for the simple speech and object stimuli, individuals with ASD did not. Specifically, individuals with ASD showed less tolerance of asynchrony for speech stimuli compared to object stimuli. In individuals with ASD, decreased tolerance for asynchrony in speech stimuli was associated with higher ratings of autism symptom severity. Conclusions These results suggest that audiovisual perception in ASD may vary for speech and object stimuli beyond what can be accounted for by stimulus complexity.
