189. Psychometrics of Hierarchical Drift Diffusion Modeling of the Flanker Task: Reliability and Associations With Event-Related Potentials and Neuropsychological Performance

Computational models are increasingly used to study cognitive functions in psychiatric disorders, but little research has compared the psychometric properties of their parameters to simpler behavioral measures. We examined the reliability and validity of three behavioral measures of a cognitive control task: the Eriksen flanker, specifically 1) raw accuracy, 2) a NIH Toolbox derived score, and 3) parameters from a hierarchical drift diffusion model (HDDM).
