3.1. Instable perceptual inference in patients with schizophrenia
As expected, we found high percept survival probabilities across
temporary stimulus removals (median 96.3%, interquartile distance
8.4%), indicating the stabilizing effect of sensory predictions on perception
of the ambiguous stimulus. Remarkably, survival probabilitieswere
significantly lower in patients with schizophrenia than in healthy controls
(Fig. 2A, Z = −2.0, p = 0.02, one-sided Wilcoxon rank-sum
test), in linewith our first hypothesis of aweaker influence of stabilizing
sensory predictions in perceptual inference in schizophrenia.
