When Stopping Requires Going: Physiological Similarities Between Action Cancellation and the Cancellation of Action Cancellation.

ABSTRACT: The reactive cancellation of real-world actions typically requires complex combinations of both muscle contraction and/or muscle suppression. However, current experimental paradigms solely examine contexts in which action cancellation requires muscle suppression. To provide fundamental insights into inhibitory control mechanisms, we directly compared the latency of action cancellation in novel paradigms where 'stopping' required either suppression of planned activation or reinstatement of ongoing activity. Twenty healthy adults (mean age = 32.2 years) completed novel variants of the stop signal task (SST) in which each trial began with tonic force production to depress two buttons. When a go signal appeared, participants were required to release these buttons. On a subset of trials, a stop
