Event Title

Inhibitory Control in Mind and Brain: An Interactive Race Model of Countermanding Saccades

Description

The stop-signal task has been used to study normal cognitive control and clinical dysfunction. Its utility is derived from a race model that accounts for performance and provides an estimate of the time it takes to stop a movement. This model posits a race between “go” and “stop” processes with stochastically independent finish times. In this presentation, Boucher will report how a simple, competitive network can provide an account of what is measured by stop-signal reaction time.
