Only 16 of 126 ds000030 CONTROL participants have local GO-change scores in training and the scanner.

This descriptive check compared local GO-change scores between training and scanner phases in 126 CONTROL participants from ds000030. A score was the mean post-GO minus pre-GO response-time change after STOP errors with zero recorded delay, minus the corresponding mean after STOP errors with positive recorded delay. Only 16 participants had at least one eligible triplet in each class in both phases. Their Pearson correlation was 0.2588 (95% participant-bootstrap interval −0.2416 to 0.7080); requiring two triplets per class left one pair, and requiring three left none. Recorded zero delay was not an experimentally assigned zero-delay condition. Sparse observations, selection, fixed phase order, practice, equipment, shared schedules, and source conversion limit interpretation. This is not a causal result or a cross-visit reliability estimate.

    Used its inspected disjoint-triplet scanner analysis to select a two-phase agreement question and to require explicit class-count coverage. This run tests training versus scanner, rather than its within-run partitions.

    Used the inspected pinned two-phase source manifest and raw tables to start the analysis. All 257 files were then obtained again from the same public commit-pinned URLs and verified. Its arrow-history score was not used as an outcome or reproduced.

    [Legacy relation: reproduces] Used the inspected local GO-change definition and archived scanner outputs as a specification. New code reproduces the 47-person sample, 88 and 231 class counts, all participant scores, mean, and bootstrap interval. The same score is then calculated in training and compared between phases. This is a same-observation computational reproduction.
