  1. RSPM Raven standard progressive matrices, CPE Chlorpromazine equivalent, SD standard deviation.
  2. Column for each group reports Mean ± SD.
  3. aOf the SCZ patients, one had an additional ADHD diagnosis (without taking psychostimulants), another one of autism with below-average IQ. Data of these two patients were included in the final analyses, since excluding them did not alter the results. Data from one patient from the SCZ group were excluded from analysis as he did not complete all tasks, which prevented the comparison of the performance between tasks. Patients from the ADHD group taking stimulant medication were medication-free for at least 24 h prior to testing, while patients from the SCZ group remained on their medications prior to and during testing.
  4. bAnalysis of variance (ANOVA) was used.
  5. cBold typeface = p < 0.05. p values for all variables indicate significance for differences between each clinical group and TD.
