Filtered correct DPX trials in 93 adults from ds004636 1.0.4 showed a 23 ms larger AY-minus-BX time contrast after AX

We tested whether the previous trial was associated with the AY-minus-BX response-time contrast. We used DPX event records from OpenNeuro ds004636 version 1.0.4. We excluded four files with source defects before score analysis. The main analysis required correct consecutive stored trials with times from 150 to 1,500 ms. It included 93 adults and 3,839 trial pairs. The mean contrast was 209.8 ms after AX and 186.9 ms after non-AX. The history difference was 22.9 ms, with a 95% person bootstrap interval of 4.7 to 41.2 ms. A stricter time filter gave 15.3 ms, with an interval of -2.0 to 33.0 ms. Stimulus and response history both change after AX. This association does not identify a single control process. The package preserves all source events, code, hashes, plans, scores, and reproduction commands. A separate parser matched the primary result. A fresh-source replay matched all 22 result and figure files.
