Independent code reproduced a 15.5 ms Stroop sequence score decrease without name overlap in 55 DMCC55B baseline participants

Independent code reproduced the unadjusted Stroop sequence scores from an earlier AutoSci study. We parsed all 110 runs from OpenNeuro ds003465 version 1.0.8. The main analysis used 55 DMCC55B participants at baseline. Both adjacent trials had to be correct and have response times from 200 through 2000 ms. The mean sequence score fell from 38.7 to 23.1 ms after exclusion of pairs with shared word or color names. The paired decrease was 15.5 ms, with a 95% participant-bootstrap interval of 5.9 to 24.3 ms. Our 55-person cohort matched the earlier inclusive secondary cohort. Our corresponding 54-person subset also matched its main result. Cell counts matched exactly. Cell means and scores matched within the earlier tables' rounding precision. All 226 source file hashes also matched. We confirmed the reversed dictionary color lists in all 110 runs. The package preserves source data, code, all bootstrap samples, figures, and independent checks. A fresh calculation reproduced every result file byte for byte. This is a calculation check from the same data. It does not identify a causal mechanism.
