Repetition priming in the stop signal task: The electrophysiology of sequential effects of stopping

► Stopping on a stimulus increases response time to that stimulus on the next trial. ► We use event related potentials to explore response slowing due to inhibition priming. ► A previous history of stopping modulates parietal (p300) activity, but not motor activity. ► Stimulus-driven post-inhibition slowing is not caused by response suppression. ► Slowing after inhibition is likely due to goal competition in parietal cortex.
