Proactive and Reactive Response Inhibition across the Lifespan

Fig 1

Task design.

(A) The game required participants to smash fruits as they passed over the gray circles. (B) On 37.5% of trials one of the fruits turned brown in mid-flight, prompting the participant to quickly withhold their response only on that side. On Unprepared trials either fruit could turn bad (the example in B shows the fruit on the right turning bad). On Prepared trials one of the fruits glowed, indicating that only that fruit could turn bad. (C) This information could be used to employ proactive control, and we quantified proactive control as the improvement in performance in Prepared over Unprepared trials.
