Global reproducibility in patients with schizophrenia and controls, and correlation between global reproducibility and task performance. (Left) The percentage of spatial overlap (%Ovlp) was significantly lower in patients with schizophrenia than in controls (t16.5 = 2.64, p = 0.017). (Right) Percentage of overlap was not correlated with comprehension scores in session 1 for controls (r = 0.12, p = 0.73) but was positively correlated with comprehension scores for patients with schizophrenia (r = 0.82, p = 0.004). Solid lines represent the regression lines (controls: percentage overlap = 0.64 × score + 41.93, R2 = 0.02; schizophrenia patients: percentage overlap = 3.79 × score + 13.60, R2 = 0.68); dotted lines represent the mean comprehension scores in session 1.
