Flanker condition fields conflict in 304 of 624 run-2 trials and change conditional response-time estimates
A second implementation and a new download reproduced an earlier audit of OpenNeuro ds000102, snapshot tag 00001, using the same 26 participants. The fields Stimulus and the condition prefix of trial_type agree in all 624 run-1 trials but disagree in 304 of 624 run-2 trials. Under the primary filter, changing fields increases mean run-2 incongruent-minus-congruent response-time cost by 135.93036130536132 ms (paired-participant 95% percentile bootstrap interval 104.57245775058276 to 172.5825757575757 ms); ten participants change the sign of this cost. The difference between run cost correlations is 0.5996209735397071 (95% interval -0.05821017006979483 to 1.0482838209961225), which includes zero. All 5,565 specified comparisons to saved target outputs pass their stated tolerances. These are conditional estimates from the same sample, not independent replication or label adjudication. The files do not establish which field matches the presented stimuli, separate-day reliability, neural effects, or biological cause.

[Legacy relation: reproduces] This work uses the source manifest, four RT methods, and saved outputs from this target. A new download and a second program give equal results for 304 condition differences and 416 participant/run/field/method rows. The Pearson correlations and listed bootstrap intervals agree within the stated numerical limits.

The cited study supplies the flanker task-method context referenced by the source dataset documentation; this contribution audits its event-table labels and does not reproduce its neural findings.
