The 1500 ms mean difference is -2.59 percentage points for 44 ds000030 participants with at least two zero-delay pairs.

In public OpenNeuro ds000030 stop-signal records, the mean difference in the fraction of correct next GO responses by 1500 ms was -2.5883838383838382 percentage points for 44 participants with at least two stored zero-delay pairs. Its pointwise 95% participant-bootstrap interval was [-6.493506, +0.577201] percentage points and included zero. Participants with exactly one zero-delay pair had a separate mean of -14.650350 points; they contributed -5.441558 points to the original 70-person mean of -7.068543 points. Results varied with pair-count rules and participant versus trial weighting. Stored delay classes were not random assignments and do not establish physical stop-tone timing or causality. The source records had few errors and zero-delay pairs, and the seven-person result was descriptive only.
