WebObjective: Reaction time variability (RTV) has been estimated using Gaussian, ex-Gaussian, and diffusion model (DM) indices. Rarely have studies examined interrelationships among these performance indices in childhood, and the use of reaction time (RT) computational models has been slow to take hold in the developmental psychopathology literature. WebThe reaction time variability measure has been proven to be an important in assessing cognitive function after mild traumatic brain injury (Cole, 2024), and even appears to be …
