A Randomized Controlled Trial for Audiovisual Multisensory Perception in Autistic Youth

Abstract: Differences in audiovisual integration are commonly observed in autism. Temporal binding windows (TBWs) of audiovisual speech can be trained (i.e., narrowed) in non-autistic adults; this study evaluated a computer-based perceptual training in autistic youth and assessed whether treatment outcomes varied according to individual characteristics. Thirty autistic youth aged 8–21 were randomly assigned to a brief perceptual training ( n = 15) or a control condition ( n … Show more

“…Partici pants’ magnitude of integration for audiovisual speech was measured using a previously developed McGurk task (for further information regarding task development and details, see Dunham et al 2020; Feldman et al 2020, 2021). Briefly, stimuli for this task were auditory, visual, or auditory-visual clips of a female speaker saying the syllables “pa” and “ka” at a natural rate and volume with neutral affect.…”

“…This suggests that autistic individuals perform a more time-consuming analysis of bimodal compared to unimodal emotional cues but can thereby still achieve the same relative improvement of accuracy. We suppose that this compensational strategy evolves during childhood development, since previous literature identified generally larger multisensory integration deficits in younger children than in adolescents (36) and particularly, the bimodal facilitation of accuracy in speech recognition (as a social stimulus) was impaired in autistic children (7-12 years) but not adolescents [13-15 years (43)].…”

“…In the current study, we focus on multisensory facilitation (MSF) of accuracy and multisensory facilitation of response time as two distinct parameters of multisensory integration. Compared to non-autistic people, autistic individuals have been shown to benefit significantly less from multimodal presentation, in terms of both accuracy as well as response time, with an overall effect size of −0.41, indicating a small-to-moderate effect across various stimuli in a recent meta-analysis (36). Thereby, multisensory facilitation of response time has been frequently investigated using simple, non-social stimuli (e.g., beeps or flashes) and comparing response times to unimodal and audiovisual presentation.…”

“…Autism spectrum disorder (ASD), characterized by deficits in social communication and the presence of restricted, repetitive behaviors or interests, is a neurodevelopmental disorder affecting approximately 2.3% children aged 8 years in the US and approximately 2.2% of adults (1). ASD children have obvious defects in visual and auditory information integration compared with normal children (2,3). The ability to integrate the visual and auditory components…”

“…Autism spectrum disorder (ASD), characterized by deficits in social communication and the presence of restricted, repetitive behaviors or interests, is a neurodevelopmental disorder affecting approximately 2.3% children aged 8 years in the US and approximately 2.2% of adults ( 1 ). ASD children have obvious defects in visual and auditory information integration compared with normal children ( 2 , 3 ). The ability to integrate the visual and auditory components of social stimuli is theorized to be particularly critical to developing accurate, unified representations of the sensory world and foundational to the development of higher-order social, communication, and cognitive skills ( 4 ).…”
