Stop-Signal Reaction Time Task
The Stop-Signal Reaction Time (SSRT) task is a behavioral measure of response inhibition and executive control. Participants make rapid responses to go signals but must cancel responses when an occasional stop signal appears. By analyzing how successfully they inhibit responses and estimating the latency of inhibition (Stop-Signal Reaction Time), researchers measure the speed and efficiency of the neural inhibitory processes that enable self-control, impulse control, and behavioral flexibility.
