The sense of agency refers to the feeling initiating and controlling one's actions their resulting effects on external environment.

Social cognitive and neurocognitive performance is impacted in autism schizophrenia spectrum disorders (SSDs). Here, we compared social across a large transdiagnostic sample of participants with autism, SSDs, typically developing controls (TDCs). Participants (total N = 584; 100, SSDs 275, TDCs 209; aged 16-55 years; 61% male assigned at birth) completed lower-level (eg, emotion processing) higher-level theory mind) tasks, the MATRICS Consensus Cognitive Battery, measure functioning. Nonparametric groupwise comparisons were undertaken, adjusting for age sex, within-group correlations used to examine associations between cognition, neurocognition, Autistic SSD groups performed worse than on lower- few autism-SSD differences found. Autism had lower scores TDCs; demonstrated processing speed, working memory, verbal learning, visual learning versus autism. Positive tasks neurocognition observed groups, self-reported measures empathy consistently correlated This study represents largest comparison both cognition an autism/SSD reported date. those showed similar relative controls, while was less SSDs. These findings underscore importance research into mechanisms underlying deficits highlight potential interventions.
