Differences in cognitive scores on the MCCB between the SCH and HC groups were examined via two-sample t-tests. SCH, schizophrenia group; HC, healthy control group; PANSS, Positive and Negative Syndrome Scale; MCCB, MATRICS Consensus Cognitive Battery; SOP, speed of processing; AV, attention/vigilance; WM, working memory; Vrbl_Lrng, verbal learning and memory; Vis_Lrng, visual learning and memory; RPS, reasoning and problem-solving; SC, social cognition.
