In this final report for my AFOSR grant, I discuss significant findings over the 3 year grant period, including a systematic examination of diffusion model fitting packages along with an evaluation of individual differences and the effects of the number of observations on parameter recovery practice effects and the ability of the model to recover parameter values with low numbers of observations recovery of individual differences using simulated data bias and accuracy of parameter recovery. I discuss results from a study of the effects of sleep deprivation on memory, a study on driving simulation, and another study on the effects of video gaming on decision making. I also discuss new models for the gono-go task and for multichoice decisions and confidence judgments, and results from our continued investigation of integrating models of perceptual processing with decision models and another on examining psychometric functions with the diffusion model.
