Perception of visual-tactile asynchrony, bodily perceptual aberrations, and bodily illusions in schizophrenia

Body perception can be altered in individuals with schizophrenia resulting experiences of undefined boundaries, loss ownership, and size changes. These may also more susceptible to the rubber hand illusion (RHI: an body that induced neurotypical populations), but findings are mixed. Furthermore, multisensory timing, which is thought fundamental for perception, schizophrenia. We tested whether temporal relationship between visual tactile signals predicts self-reported perceptual aberrations RHI susceptibility. found sensitivity detect asynchronies reduced this a significant predictor bodily symptoms. In contrast, we no evidence direct asynchrony detection Instead, our suggest experiencing symptoms increases likelihood endorsing unusual experiences, higher self-ratings not proprioceptive drift scores. Our provide new insight into factors underlie report perceptions
