Impulsive responding and the sustained attention   to response task.
Two studies investigated whether the sustained attention to response task (SART) is a better measure of impulsive responding than of sustained attention. Participants performed target detection tasks with global-local letter stimuli using one of two response formats: standard, responding to targets; and SART, withholding to targets. In the first experiment, performance in the SART changed rapidly over time, whereas performance in the standard format was stable over time. In the second experiment, performance in the SART was susceptible to global-local condensation tasks, a result previously found with highly impulsive individuals. Overall the results indicate that the SART is sensitive to impulsive responding.
