The Pearson correlation difference is less than zero after adjustment for training GO time in 241 ds000030 participants.

In 241 OpenNeuro ds000030 participants, the raw Pearson correlation difference between B and S scanner halves was positive for chronological and interleaved splits. After linear adjustment for mean training GO time, the point differences were negative, but both 95% intervals included zero. Partial Spearman estimates remained positive, and the analysis cannot establish equal correlations, a biological cause, or a causal effect.

    The archived public training event tables supply the 266 paired training GO reaction-time records used for the adjustment. Their bytes and Git blob identifiers agree with the pinned public source version.

    Its schedule definition uses ordered trial types, arrow directions, and following NULL durations. The new code applies that definition to form the 39 groups for the schedule bootstrap.

    Its executed shared-GO-trial comparison supplies the reason to test a GO-time covariate from a different run. The present calculation uses different training trials and does not repeat its shared-trial experiment.

    [Legacy relation: reproduces] New code reproduces all 21,280 numeric score-table cells, all 241 primary participant identifiers, and the raw half-score correlation and covariance contrasts. This comparison does not reproduce the prior bootstrap draws.
