Both accuracy and task completion times were analyzed. Executive functions and processing speed were evaluated using standard neuropsychological measures. Group comparisons and regression analyses were performed adjusting for age, education, and executive performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>DM1 patients showed different patterns for accuracy and completion time across social-cognitive tasks. RMET accuracy was reduced, whereas SET accuracy was comparable between groups. In contrast, completion times were consistently prolonged across all social-cognition tasks in DM1. These differences remained significant after controlling for executive function. SET completion time showed stronger discriminative performance than SET accuracy measures, whereas RMET completion time and accuracy showed comparable discriminative performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Social cognition in DM1 is characterized by prolonged completion times, while accuracy is relatively preserved on several measures. This discrepancy suggests that conventional accuracy-based assessments may not fully capture subtle differences in social-cognitive performance. Temporal metrics may reveal aspects of social cognition performance not detected by accuracy-based assessments alone and contribute to a more comprehensive neuropsychological evaluation.<\/jats:p>\n
