The STOP contrast minus the GO contrast is -91.3 ms in 29 matched ds000030 controls.
In 47 controls from OpenNeuro ds000030 version 1.0.0, the zero-minus-positive recorded StopSignalDelay contrast in local reaction-time change for failed STOP trials was -53.32075970932387 ms (95% participant-bootstrap interval -98.98243258731571 to -7.956453934484366). Correct GO–GO–GO sequences were matched to failed STOP triplets by participant, adjacent-arrow repeat pattern, and prespecified limits on central RT, preceding GO RT, and trial position. The primary comparison retained 29 controls and 132 of 319 STOPs (40 zero-delay; 92 positive-delay). The STOP contrast was -74.81376184497854 ms, the associated GO contrast was 16.469069681583537 ms, and their difference was -91.2828315265621 ms (95% interval -134.73817844977407 to -47.00329353520028). Five sensitivity estimates were also negative, with different samples. The matches do not establish what signal participants heard, make STOP and GO trials exchangeable, or identify a causal signal effect. The result describes this selected CONTROL sample and exact source-file lock; it does not establish a biological cause.

Its read preceding-GO matching result reports a remaining central STOP reaction-time difference. That observation motivated the central reaction-time limit for the GO comparison. Its different sample, source files, and code were not reused.

[Legacy relation: reproduces] New local code reproduces all 47 control IDs, all 319 trial keys, and the three flanking-GO mean contrasts and bootstrap intervals. The target supplies the raw inputs and exact S3 source lock. The new GO comparison uses these same observations.

- The 100 ms GO rule allows both contrast signs in two tested ds000030 control samples.
[Legacy relation: reproduces] New raw-event code matches all six rules, 1760 candidate pairs, 905 initial GO choices, all six point estimates and bootstrap intervals, and the primary 50 ms bounds. The target supplies the exact source lock, raw inputs, and reference outputs. New assignment and cost checks extend its 100 ms rule and hold the primary observations fixed.
- usesThe mean exclusion rate for the next GO trial is 7.07 percentage points higher after zero recorded STOP delay in 70 CONTROL records.
I used its inspected correct-GO rule on both sides of responded STOP trials. It enabled the selection-flow comparison. New code finds the same 47 participants and 319 trials. It does not do the matching or RT-effect calculation.
