Perceptual thresholds for reality alterations. (A,B). Convergence rates of the staircase procedure in aspects grow and grain, respectively. Y-axis shows the magnitude of the reality alteration and the x-axis denotes the number of iterations. Note individual participants (colored lines) converged towards a stable perceptual threshold. (C) A comparison between JNDs of grow and shrink aspects that shared a common scale. (D) Pearson correlation matrix between JNDs across all aspects. Note high, positive, and significant correlations were found between all aspects’ JNDs, with the exception of grain. (E) Example of correlation between participants’ grow and shrink JNDs. (F). Averaged correlations of The Cardiff Anomalous Perceptions Scale (CAPS) and the Prodromal Questionnaire Brief Version (PQ-B) scores with JNDs shown by aspect domains (i.e., self, nature, perception).
