Mean GO reaction time is higher at the first three GO trials after STOP in 125 ds000030 control runs.
In 125 control participants from OpenNeuro ds000030, mean correct GO reaction time was higher at the first, second, and third active-trial positions after the most recent STOP than at a reference position with no STOP in the prior three active trials. Equal-participant mean differences were 50.22, 23.87, and 15.34 ms; approximate simultaneous 95% participant-bootstrap intervals were 41.77–58.68, 15.89–31.85, and 7.44–23.24 ms. Seven planned sensitivity calculations retained positive differences. These observational comparisons do not estimate a causal STOP effect or a neural mechanism. They use the observed schedule mix, assume independent participants for approximate intervals, and form an exploratory extension on the same data as an earlier next-GO result. The tested result does not establish generalization to new schedules or participants.

The 131-file source lock, public event tables, and TrialOutcome label audit enabled the three-position history analysis. The same data also give the reported 42.61 ms comparison to two decimals.

- The two-sided model estimates a 15.27 ms third-GO difference in 125 ds000030 control runs
[Legacy relation: reproduces] New code gives the same 125 participant IDs, trial counts, mean differences, and interval limits. The calculation uses the same source observations.
- The third GO contrast is 13.55 ms after adjustment for three arrow transitions in 125 ds000030 control runs.
[Legacy relation: reproduces] New code on the same locked files gives the same 125 participant identifiers, all 504 participant/class counts, raw mean contrasts, and three-value interval limits. This relation does not cover the target common-window or sensitivity results.
- usesThe STOP history model has 2.31% lower mean squared error in 38 ds000030 schedule tests.
Its nearest-STOP rule for the previous three active positions supplied the history inputs and prediction question. This run tests excluded-schedule prediction error with new code. It does not repeat the earlier descriptive means or claim causality.
- usesThe third GO contrast is 15.92 ms with arrow pattern adjustment in 125 ds000030 control runs.
We used the locked event tables, participant selection, and third GO and reference definitions. The new code gives the same raw contrast and counts.
