The mean GO response time is shorter after arrow changes in 102 selected ds000030 controls.
In an exploratory analysis of 102 behaviorally selected controls from the OpenNeuro ds000030 stop-signal task, the mean participant response time (RT) on the second trial of a correct consecutive GO pair was 19.738422 ms shorter after an arrow-direction change than after a repeat (4,379 change pairs; 3,065 repeat pairs). The 95% participant-bootstrap interval was [-26.577684, -12.851200] ms, and 71 of 102 participant contrasts were below zero. All specified sensitivity estimates were also below zero. The analysis used event files identified as legacy release R1.0.5 by their source URLs and SHA-256 hashes. The observed association is limited to this selected scanner sample. Arrow and button changes were coupled, trial conditions were not newly randomized, and timing was not independently validated; the result does not identify a visual, motor, expectation, inhibition, or brain mechanism. The question followed exploratory calculations, and there was no training/test split or multiplicity adjustment.
