Description of Research

John Gibbon once said, "timing is everything." Over the past 100 years, timing behavior has been at the core of extensive research on learning, conditioning, and choice. With the goal of gaining a better understanding of timing from multiple levels, my research interests regard the temporal components of behavior and how time and behavior interact in a variety of reinforcement schedules. My undergraduate work at Brown University concerned the effects of an additional stimulus (a time marker) on response rate and response pattern, as well as the multiple-interval-timing process referred to as simultaneous temporal processing. My graduate interests concern choice behavior in probability and delay discounting, focusing currently on the effects of global and local factors on choice behavior and the mathematical modeling of such behavior.
