Research interests in our laboratory involve a range from mathematical psychology, cognitive psychology, decision making, and neuroscience.
 
Currently, we are applying diffusion decision models to topics in decision making, cognitive decisions, and neuroscience.  These include trying to understand the effects of aging, memory disorders, concussion, and sleep deprivation on memory and decision making, to understand cognitive and perceptual processes involved in driving, to understand the neural basis of decision making using EEG, fMRI, and single cell recording data (from monkeys).  Diffusion models use stochastic differential equations and recent modeling has extended the standard two choice model to single response task and confidence judgments in memory (multi-alternative decisions).
