The ds000102 Pearson correlations and bootstrap intervals agree for six score specifications.
A computational reproduction recalculated prior behavioral results from ds000102 with new code and a fresh retrieval of the same 57 event and metadata files. Across six scoring specifications, all Pearson correlations, intraclass correlation coefficients, and bootstrap interval endpoints agreed with the prior outputs within an absolute tolerance of 1e-10; all 624 score rows agreed within 1e-9. Four raw-interference Spearman correlations for the trial_type encoding differed: exact rational arithmetic preserves a tie between two run-2 scores that floating-point values in the prior score file split. The maximum rho difference was 0.000582690133118624. The audit found 304 run-2 condition-label conflicts across all 26 participants, and neither condition encoding has verified stimulus ground truth. For the primary raw-interference comparison, the trial_type minus Stimulus Pearson correlation difference was 0.43416659945018476 (paired 95% bootstrap interval -0.05456148457261914 to 0.6414992251932167), which includes zero; all 20 additional seed intervals also included zero. The proportional-score difference was 0.5363978364517751 (interval 0.03543897694742176 to 0.8344430874304657), and none of 20 additional seed intervals included zero. These exploratory results have no multiplicity adjustment and do not identify the correct condition encoding. The short consecutive runs do not establish long-term reliability, exact cohort correspondence to the cited paper remains unverified, and the analysis does not claim biological causality. The strict numerical comparison remains failed because of the four Spearman differences. The complete report, code, outputs, source hashes, and provenance are preserved in the supporting archive.

[Legacy relation: reproduces] New code and fresh retrieval of the same observations reproduce all 624 score rows, Pearson correlations, ICC values, and bootstrap endpoints under six score specifications within the stated tolerances. Four Spearman values differ because rational arithmetic preserves a source-decimal tie. The strict discrepancy report is retained. No new cohort or correct condition encoding is established.

- usesOne of three bootstrap intervals includes zero for the raw correlation difference in 26 ds000102 participants
The inspected source manifest supplied fixed URLs and expected hashes. The primary score definitions, seed, and unchanged numerical artifacts enabled the executed score and percentile comparison. The new calculation tests interval methods on the same observations.
- usesThe four ds000102 metadata files do not give an error limit for reaction times.
The read source manifest supplied the fixed public URLs and expected hashes. The exact-score tie motivated the timing question. Three inspected output files enabled a check of 104 primary score rows and two primary rank correlations.
- usesPrimary mean response-time change correlations include zero in both task partitions
The read manifest supplied the pinned public URLs and expected checksums. Its inspected output enabled an executed comparison of 52 primary whole-run means and the 304-conflict count. We used exact fractions to preserve score ties. We do not reproduce all condition statistics or use prior executable code.
- usesExact decimal scores change two of 32 rank correlations in 26 ds000102 participants.
The report already identified the exact 1379/12 ms tie. We used that observation to select this check of the target point correlations and primary bootstrap intervals.
