The ds003465 version 1.0.8 Stroop dictionary reverses both color groups in all 110 matched task runs
We checked the Stroop color groups in OpenNeuro ds003465 version 1.0.8. All 110 event tables matched their task logs for onset, group, and congruency. The dictionary reversed both color group descriptions in all 11,880 trials from 55 people. We supply a repair that changes only these two descriptions. A test that selected PC50 trials by the source color description gave a mean Stroop cost of 132.4 ms. The corrected selection gave 102.0 ms. The mean paired difference was 30.5 ms, with a 95% person bootstrap interval of 16.3 to 45.0 ms. The run 1 interval crossed zero. This test shows a possible effect of color-based selection. It does not establish an error in any earlier study or a causal control mechanism. The package preserves unchanged source files, fixed source hashes, all person estimates, bootstrap draws, code, and offline reproduction steps. A separate calculation and a complete new public retrieval passed all checks.

- usesAverage Stroop cost had higher correlation between baseline runs than the set difference in 55 ds003465 v1.0.8 adults
This study uses the prior audit source files, fixed source manifest, Git annex pointers, and event-label check. It extends the audit with a new paired comparison of person correlations across runs.
- usesThe Stroop sequence estimate decreased without shared identities in ds003465 v1.0.8 for correct pairs with current times of 0.2–2.0 seconds
The prior audit supplied the initial source archive and showed reversed color group descriptions. This study checked the archive with a fresh public download. It used the task logs to check color group identities before calculation of sequence effects.
- supportsIndependent code reproduced a 15.5 ms Stroop sequence score decrease without name overlap in 55 DMCC55B baseline participants
An independent comparison of recorded trial labels and target names confirmed reversed task dictionary color lists in all 110 runs of ds003465 version 1.0.8. We did not repeat the earlier color-group response-cost comparisons.
- usesPC50 Stroop cost was 45 ms smaller after incongruent MC trials across disjoint color sets in two pooled runs from 52 selected ds003465 v1.0.8 participants
The earlier audit established that Stroop event labels match task logs and that the dictionary color lists are reversed. We used its source archive, fixed Git records, and MIT retrieval code. We repeated the source-log checks and added a new adjacent-trial sequence analysis across disjoint color sets.
- usesRemoving shared color names creates a negative Stroop contrast under a stated group-cost model
We fetched its unchanged 110 event tables, 110 task logs, source metadata, and pinned provenance. We copied its retrieval recipe and corrected one provenance note. Its dictionary audit established which colors belong to each event group. A fresh public download matched all source bytes. We wrote a new parser and sequence analysis. No earlier behavioral estimate was an input.
