Removing eligible trial pairs with shared words or colors reduced the Stroop sequence contrast in 54 ds003465 version 1.0.8 adults
For eligible adjacent trials, removing shared words and colors reduced the Stroop sequence contrast in 54 adults. The source was OpenNeuro ds003465 version 1.0.8. Eligible pairs had two correct responses within one task block. Both response times were from 0.2 to 2.0 seconds. The mean contrast fell from 39.17 ms to 23.24 ms. The paired decrease was 15.93 ms, with a 95% participant bootstrap interval from 6.10 to 25.03 ms. The remaining contrast had an interval from 6.77 to 39.08 ms. Each person had equal weight. The study also found redundant model controls and a disagreement between metadata color names and row condition codes. An independent model basis preserved the control space and permitted a unique interaction estimate. The remaining contrast does not prove conflict adaptation. Removing shared features changes the trial sample, and word-response associations remain. A check restricted to two PC50 trials retained only four people. The package includes 226 unchanged source files, code, source hashes, all results, and reproduction instructions. Independent decimal and QR checks passed. Separate analyses, including a run from freshly retrieved inputs, reproduced all 25 numeric output files by SHA-256.

Its two-choice gender Stroop result motivated checks of feature transitions and model rank in this separate eight-color task. This study uses new data and code. It does not repeat that earlier empirical result.

We used its complete no-overlap score in an eight-color Stroop task to check the scope of our structural-zero result. More identities can permit a complete score. We did not reuse its code or data.
- Independent code reproduced a 15.5 ms Stroop sequence score decrease without name overlap in 55 DMCC55B baseline participants
[Legacy relation: reproduces] Independent source parsing reproduced the unadjusted adjacent-pair cell counts, means, and sequence scores. Our main 55-person cohort matches the earlier inclusive secondary cohort. Our corresponding 54-person subset matches its main cohort. All 226 source file hashes match. Earlier result tables were read only after our calculations and source checks were complete. We did not repeat the adjusted models, sign-flip tests, or all secondary analyses.
- Removing shared color names creates a negative Stroop contrast under a stated group-cost model
[Legacy relation: reproduces] Our separate parser and behavior calculations reproduce all 440 cell counts and 605 time values in its all-55 sensitivity table. This comparison uses the same public source data, not another cohort. The bootstrap seeds and draw counts differ, so we do not claim to reproduce its intervals. We do not claim the behavior decrease as a new discovery. We add exact group-transition counts by sequence, a selection proof and example, an equal group weight check, and an original-adjacency tool.
