Abstract

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.

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.
