Increasing audiovisual speech integration in autism through enhanced attention to mouth

Increasing audiovisual speech integration in autism through enhanced attention to mouth INTRODUCTIONAudiovisual speech integration entails the combination of auditory and visual parts of a speech into a coherent representation (Altieri et al., 2011). Reduced audiovisual integration in McGurk tasks has been reported in autistic children (AC) (Bebko et al., 2014; Iarocci et al., 2010; Irwin et al., 2011; Mongillo et al., 2008; Stevenson et al., 2014). Autism is a neurodevelopmental condition characterized by difficulties in social interactions and communications, as well as restricted and repetitive patterns of behavior (DSM‐5; American Psychiatric Association, 2013). The reduced audiovisual speech integration in AC was associated with language or communication difficulties (Feldman et al., 2018).Audiovisual speech integration has been measured by susceptibility to the McGurk effect, which occurs when the auditory part of a phoneme is dubbed onto the mouth movements of another (visually presented) phoneme, leading to a fused perception of a new phoneme (McGurk & MacDonald, 1976). For example, when the auditory phoneme “ba” was dubbed onto the visual mouth movements of “ga,” people often reported a fused perception of “da” (McGurk & MacDonald, 1976). Using the McGurk effect paradigm, a series of studies investigated audiovisual speech integration in AC (Bebko et al., 2014; Iarocci et al., 2010; Irwin et al., 2011; Mongillo et al., 2008; Stevenson et al., 2014; Woynaroski et al., 2013).

Abstract

INTRODUCTIONAudiovisual speech integration entails the combination of auditory and visual parts of a speech into a coherent representation (Altieri et al., 2011). Reduced audiovisual integration in McGurk tasks has been reported in autistic children (AC) (Bebko et al., 2014; Iarocci et al., 2010; Irwin et al., 2011; Mongillo et al., 2008; Stevenson et al., 2014). Autism is a neurodevelopmental condition characterized by difficulties in social interactions and communications, as well as restricted and repetitive patterns of behavior (DSM‐5; American Psychiatric Association, 2013). The reduced audiovisual speech integration in AC was associated with language or communication difficulties (Feldman et al., 2018).Audiovisual speech integration has been measured by susceptibility to the McGurk effect, which occurs when the auditory part of a phoneme is dubbed onto the mouth movements of another (visually presented) phoneme, leading to a fused perception of a new phoneme (McGurk & MacDonald, 1976). For example, when the auditory phoneme “ba” was dubbed onto the visual mouth movements of “ga,” people often reported a fused perception of “da” (McGurk & MacDonald, 1976).
