Positive-delay failures show larger local GO RT increases than zero-delay failures in ds000030 1.0.0
In a descriptive analysis of the OpenNeuro ds000030 1.0.0 scanner stop-signal task, we compared the next-minus-previous correct GO reaction-time (RT) change around failed STOP trials with zero versus positive recorded stop delays. Among 102 paired participants, positive-delay failures had a 67.0 ms larger mean local change (10,000-participant-resample percentile 95% interval 37.4 to 96.0 ms); the median participant contrast was 74.5 ms, with individual contrasts from -403.5 to 472.7 ms. The result describes recorded trial classes in a selected mixed sample. Zero-delay failures were sparse, and the groups differed in STOP response speed, preceding GO RT, planned delay, and trial position. The analysis does not establish tone delivery, inhibition latency, diagnostic differences, or a causal mechanism; response-speed selection and trial history limit interpretation.

Used the verified raw event-table subset and pinned source manifest from this publication; they enabled a new sequential GO RT comparison. No prior estimator code was executed or used.

- usesTask schedule data predict later trial labels with 99.72% accuracy in 266 ds000030 participant tests
Its read body reports 39 distinct trial-type and arrow sequences and warns about shared schedule structure. This observation helped define the schedule-holdout test. The present work does not claim that count as new and does not reproduce its reaction-time contrasts.
- The mean difference in local GO change is 96.8 ms after schedule reference subtraction in 95 ds000030 participants.
[Legacy relation: reproduces] The new code uses the 270 archived source files and repeats the local GO calculation. It reproduces all 102 participant IDs, 466 positive-delay trials, 195 zero-delay trials, the mean, and the seeded bootstrap interval. This is a calculation on the same public observations.
- usesThe mean difference in local GO reaction-time change is 119.4 ms in 32 matched ds000030 1.0.0 participants.
Used its 270 hash-verified raw source files, pinned manifest, and saved primary participant values. These inputs enabled the new fixed-rule trial match and a 102-participant point-value reproduction.
- Both GO baselines give a positive mean difference between STOP classes in 89 ds000030 participants.
[Legacy relation: reproduces] Recomputed all 1,578 eligible failed-triplet source keys, 102 paired participant class counts and means, the group mean, and the specified bootstrap interval from the same verified raw event tables. Maximum numerical difference was 0 ms. No published code ran. This is computational reproduction on the same observations; it does not independently verify biology or sound timing.
