“…Hence, the behavioral data suggest no substantial perceptual alterations in SCZ. Given that previous studies have reported aberrant multisensory processing in SCZ (de Boer-Schellekens et al, 2014), the lack of perceptual alterations in the current study is somewhat surprising. In unisensory processing, aberrant neural processing often coincides with altered perception, which is reflected in behavioral deficits (Senkowski and Gallinat, 2015; Uhlhaas and Singer, 2015).…”

Recent behavioral and neuroimaging studies have suggested multisensory processing deficits in patients with schizophrenia (SCZ). Thus far, the neural mechanisms underlying these deficits are not well understood. Previous studies with unisensory stimulation have shown altered neural oscillations in SCZ. As such, altered oscillations could contribute to aberrant multisensory processing in this patient group. To test this assumption, we conducted an electroencephalography (EEG) study in 15 SCZ and 15 control participants in whom we examined neural oscillations and event-related potentials (ERPs) in the sound-induced flash illusion (SIFI). In the SIFI multiple auditory stimuli that are presented alongside a single visual stimulus can induce the illusory percept of multiple visual stimuli. In SCZ and control participants we compared ERPs and neural oscillations between trials that induced an illusion and trials that did not induce an illusion. On the behavioral level, SCZ (55.7%) and control participants (55.4%) did not significantly differ in illusion rates. The analysis of ERPs revealed diminished amplitudes and altered multisensory processing in SCZ compared to controls around 135 ms after stimulus onset. Moreover, the analysis of neural oscillations revealed altered 25–35 Hz power after 100 to 150 ms over occipital scalp for SCZ compared to controls. Our findings extend previous observations of aberrant neural oscillations in unisensory perception paradigms. They suggest that altered ERPs and altered occipital beta/gamma band power reflect aberrant multisensory processing in SCZ.

“…In support of these theories, there have been numerous empirical findings of impaired temporal processing of sensory inputs in individuals with schizophrenia, both in the visual modality alone (Capa, Duval, Blaison, & Giersch, 2014;de Boer-Schellekens, Stekelenburg, Maes, Van Gool, & Vroomen, 2014;Giersch et al, 2009;Lalanne, Van Assche, Wang, & Giersch, 2012;Schmidt, McFarland, Ahmed, McDonald, & Elliott, 2011;Tenckhoff, Tost, & Braus, 2002) and in audiovisual modalities together (Foucher, Lacambre, Pham, Giersch, & Elliott, 2007;Martin, Giersch, Huron, & Wassenhove, 2013;Noel, Stevenson, & Wallace, 2018;Stevenson, Park, et al, 2017). Individuals with schizophrenia also have decreased audiovisual multisensory integration compared to controls (de Jong, Hodiamont, Van den Stock, & de Gelder, 2009;Tseng et al, 2015;Williams, Light, Braff, & Ramachandran, 2010) (Zhou et al, 2018).…”

Schizotypal traits are not related to multisensory integration or audiovisual speech perception

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.

“…Given the known toj and sj differences in measuring synchrony perception (e.g., García-Pérez & Alcalá-Quintana, 2012;Vatakis et al, 2008) and the differential findings for longer vs. shorter intervals (e.g., de Boer-Schellekens et al, 2014;Lalanne, van Assche, & Giersch 2012a;Martin et al, 2013), Capa and colleagues (2014) compared patient performance in tojs and sjs utilizing the same stimuli. This experimental set-up allowed them to address whether sz is associated with distorted temporal ordering, in which case tojs should be afflicted more than sjs, or with distortions only at brief time intervals, in which case both tasks should be afflicted at the same level.…”
