“…controls, suggesting either poorer lip-reading abilities or poorer multisensory integration, or a combination of both (Ross, Saint-Amour, Leavitt, Molholm, et al, 2007), though without a visual-only condition in this previous study it is unknown whether lip-reading abilities were actually poorer in individuals with schizophrenia. Individuals with schizophrenia may also be poorer at lip-reading sentences (Myslobodsky, Goldberg, Johnson, Hicks, & Weinberger, 1992) and single words (Schonauer, Achtergarde, & Reker, 1998). Individuals with schizophrenia also show less neural activation compared to controls in response to silent visual speech, specifically with less activation in the posterior inferior temporal cortex, occipital cortical areas, temporal areas, and the inferior frontal gyrus being found (Surguladze et al, 2001).…”

Multisensory integration, the process by which sensory information from different sensory modalities are bound together, is hypothesized to contribute to perceptual symptomatology in schizophrenia, in whom multisensory integration differences have been consistently found. Evidence is emerging that these differences extend across the schizophrenia spectrum, including individuals in the general population with higher levels of schizotypal traits. In the current study, we used the McGurk task as a measure of multisensory integration. We measured schizotypal traits using the Schizotypal Personality Questionnaire (SPQ), hypothesizing that higher levels of schizotypal traits, specifically Unusual Perceptual Experiences and Odd Speech subscales, would be associated with decreased multisensory integration of speech. Surprisingly, Unusual Perceptual Experiences were not associated with multisensory integration. However, Odd Speech was associated with multisensory integration, and this association extended more broadly across the Disorganized factor of the SPQ, including Odd or Eccentric Behaviour. Individuals with higher levels of Odd or Eccentric Behaviour scores also demonstrated poorer lip-reading abilities, which partially explained performance in the McGurk task. This suggests that aberrant perceptual processes affecting individuals across the schizophrenia spectrum may relate to disorganized symptomatology.

“…Increased attention to irrelevant speech may result in integrating this irrelevant speech with what is seen visually. Considering that individuals with schizophrenia are slightly poorer lip-readers (Schonauer, Achtergarde, & Reker, 1998), they may be more likely to take irrelevant auditory information and bind it mistakenly with visual facial speech information.…”

Multisensory integration, the binding of sensory information from different sensory modalities, may contribute to perceptual symptomatology in schizophrenia, including hallucinations and aberrant speech perception. Differences in multisensory integration and temporal processing, an important component of multisensory integration, are consistently found in schizophrenia. Evidence is emerging that these differences extend across the schizophrenia spectrum, including individuals in the general population with higher schizotypal traits. In the current study, we investigated the relationship between schizotypal traits and perceptual functioning, using audiovisual speech-in-noise, McGurk, and ternary synchrony judgment tasks. We measured schizotypal traits using the Schizotypal Personality Questionnaire (SPQ), hypothesizing that higher scores on Unusual Perceptual Experiences and Odd Speech subscales would be associated with decreased multisensory integration, increased susceptibility to distracting auditory speech, and less precise temporal processing. Surprisingly, neither subscales were associated with any of these measures. These results suggest that perceptual differences may not be present across the schizophrenia spectrum.
