Tradeoff between switching and response inhibition in Experiment 1. a) Perseverators on the task switching measure showed better response inhibition (i.e., faster stop signal reaction times) than switchers. b) Perseverators’ advantage in response inhibition cannot be explained by a speed-accuracy trade-off, as perseverators and switchers were equally accurate in responses to all trial types. c) Perseverators’ advantage in response inhibition cannot be explained by switchers being more primed to go, as perseverators and switchers were equally fast. In addition, both perseverators and switchers showed faster RTs for incorrect stop signal trials than for “no signal” or “go signal” trials, an indicator that serves to validate the stop signal task.
