SoP: Speed of processing; AV: Attention vigilance; WM: working memory; VrbLrn: Verbal Learning and memory; VisLrn: Visuo-spatial learning and memory; RPS: Reasoning and Problem Solving; ED: Expressive deficit Domain; Exp: Experiential Domain. Significant p value thresholds for correlations: neurocognitive domains (p < 0.0083); age (0.05); 2 domains of negative symptoms (p < 0.025). * The correlation remained significant when controlling for age and years of education.
