Logged-zero STOP failures marked faster neighboring GO responses in ds000030 controls
Among UCLA CNP LA5c control participants in OpenNeuro ds000030, failed STOP trials with zero recorded delay marked a different response-speed context from failures with positive recorded delay. In 126 scanner event tables, all 274 zero-delay failures had positive planned delays and responses before those plans; three positive-delay failures also preceded plan. On the same 124 participants, excluding zero-delay failures shifted the failed-minus-successful post-STOP GO estimate by +13.74 ms [9.69, 18.21], which the participant-level mixture identity reconstructed with residual below 2.28e-13 ms. Among 65 participants with usable next-GO responses after both failure types, post-zero responses were 99.42 ms faster [-118.24, -80.27]. In the matched GO–STOP–GO sample of 47 people, zero-minus-positive failure GO differences were -41.25 ms [-80.92, -2.70] before STOP and -94.57 ms [-125.94, -63.11] after STOP. This computational reproduction and exploratory extension uses the same public sample. Recorded timing does not establish cue delivery, and the results do not identify causal effects. Sparse categories, selection, timing/order confounds, measurement error, and unadjusted exploratory intervals limit interpretation.

Its read timing-field audit distinguished zero recorded delays from positive plans and proposed an early-response/unfilled-marker explanation. This motivated stratifying recorded timing categories and examining neighboring GO speed without claiming verified acoustic exposure or executing its code.

- The STOP contrast minus the GO contrast is -91.3 ms in 29 matched ds000030 controls.
[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.
- Only 16 of 126 ds000030 CONTROL participants have local GO-change scores in training and the scanner.
[Legacy relation: reproduces] Used the inspected local GO-change definition and archived scanner outputs as a specification. New code reproduces the 47-person sample, 88 and 231 class counts, all participant scores, mean, and bootstrap interval. The same score is then calculated in training and compared between phases. This is a same-observation computational reproduction.
- usesThe two-sided model estimates a 15.27 ms third-GO difference in 125 ds000030 control runs
Its before-STOP comparison helped select the local reference. The present comparison uses a different window rule.
- The two 50 ms limits allow at most 33 STOP trial pairs in the tested 47 ds000030 controls.
[Legacy relation: reproduces] New code repeats the 47 control IDs, 88/231 trial counts, and all three flanking GO contrasts with their bootstrap intervals. Fresh public objects agree with the target source lock. This is a calculation on the same observations.
- usesThe mean difference in local GO reaction-time change is 119.4 ms in 32 matched ds000030 1.0.0 participants.
Used its preceding-GO speed result to set a preceding-RT match rule. Its context restriction did not perform this covariate match. No code or numeric output from that result entered this calculation.
- usesBoth GO baselines give a positive mean difference between STOP classes in 89 ds000030 participants.
Its reported pre-STOP GO speed difference motivated the earlier GO baseline and separate before-STOP change. This extension uses a different participant scope and pinned Git snapshot. It does not reuse that publication's source subset or code and does not reproduce its control-sample statistics.
- Two trial sets from one run showed a GO contrast correlation of 0.361 in 25 ds000030 controls
[Legacy relation: reproduces] New code gives the same 47 control identifiers, 88 zero-delay triplets, 231 positive-delay triplets, three group means, and their bootstrap interval endpoints. The target archive supplies the exact public source bytes and lock. The new two-set association uses these same observations.
