Correct standard trials after auditory novel cues had longer adjusted response times under additive models in 140 selected ds004574 v1.0.0 records

Does an auditory novel cue have a response-time association on the next standard trial? This study used consecutive correct trial pairs from OpenNeuro ds004574 v1.0.0. Fixed rules retained 140 people: 92 with Parkinson's disease and 48 controls. Additive models adjusted each person's times for arrow directions, direction repetition, block, trial order, and recorded time gap. The mean auditory next-trial difference was 12.46 ms. The 95% person bootstrap interval was [8.51, 16.56] ms. All six planned checks had positive estimates and lower interval limits above zero. The age and gender adjusted disease-group difference was 7.05 ms, with interval [-1.19, 15.60] ms. The result shows a trial-history association. It does not identify a neural cause or a disease-specific delay. Intervals assume independent person records and condition on the fixed processing rules. The package preserves exact source bytes, hashes, a local plan, code, row links, all results, bootstrap draws, figures, and repeat instructions. Fresh retrieval reproduced all 13 result files exactly. A separate calculation checked person scores and bootstrap arithmetic.
