Description: A greater speed of information-processing may facilitate evidence acquisition during decision making and memory updating and give rise to advantages in general cognitive abilities. In this study we explore this hypothesis by using a hierarchical Bayesian cognitive modeling approach to investigate if individual differences in the velocity of evidence accumulation (a drift-diffusion model parameter that explains some variance in reaction times; RT) mediates the relationship between neural processing (estimated by event-related potentials; ERPs) and general cognitive abilities (measured by intelligence tests; IQ)
