Mean novel cue response time had higher adjusted correlation between task halves than visual minus auditory time in 141 ds004574 v1.0.0 records
We compared two response-time scores from the same novel cue trials in OpenNeuro ds004574 version 1.0.0. We selected 93 Parkinson's disease records and 48 control records. We removed linear group, age, and recorded gender effects from each half score. The correlation between blocks 1 and 2 and blocks 3 and 4 was 0.895 for the mean response time. It was 0.467 for visual minus auditory response time. The paired difference was 0.428, with a 95% person bootstrap interval from 0.300 to 0.585. All six fixed checks gave a positive difference interval. The package includes 298 source files, a local plan, code, all trial decisions, scores, bootstrap draws, figures, and reproduction instructions. An independent parser and QR calculation checked all primary draws. A fresh source download gave identical analysis results. This exploratory result concerns one short task. It does not establish repeatability across visits, clinical validity, or a neural cause.

We used this publication to obtain the archived ds004574 source bytes and full-task sample rules. Its group contrast result led to the new question about differences between people across task halves. We downloaded every source file again from the pinned public commit. This study uses the same cohort and is not an independent replication.

- usesWith valid times fixed, 150–1,000 ms invalid trial scores allowed both signs of the adjusted visual minus auditory group contrast in 144 ds004574 v1.0.0 records
The report on half-score correlations informed the question and the local exploratory plan.
- usesEarly cue calibration with weight 0.5 reduced later mean squared response time error in 141 selected ds004574 v1.0.0 records with equal cue weights
The prior same-cohort half correlations guided the forecast question, the selected sample, and the fixed calibration weight 0.5. This study adds a later-trial loss test and a loss identity that separates contrast gain from personal mean response speed. It is an exploratory extension, not an independent cohort replication.
