Results of the two-way ANOVA analysis evaluating differences between the schizophrenia, bipolar disorder, and healthy controls groups in terms of indices of implicit motor learning and normalized medians of reaction times (mRT%) in blocks 2–5 measured by the limited response time serial reaction time task variant.

BD, bipolar disorder; SZ, schizophrenia; HCs, healthy controls. Effect size lower than 0.01 was counted as negligible, 0.01–0.06 as small, 0.06–0.14 as medium, and for >0.14 as large. P-values for the main effects were adjusted for multiple comparisons (Benjamini–Hochberg correction).
