The third GO contrast is 15.92 ms with arrow pattern adjustment in 125 ds000030 control runs.
In 125 control participants from OpenNeuro ds000030, the third GO reaction-time contrast after STOP was 15.918993 ms after adjustment for four two-transition arrow patterns (95% simultaneous interval 7.861244 to 23.976742 ms). The adjusted-minus-raw change was 0.580844 ms (95% simultaneous interval −1.434850 to 2.596537 ms), which includes zero. The adjusted contrast is positive for this estimator and sample; this exploratory reuse of observations does not establish causality, a neural mechanism, or equality of adjusted and raw population contrasts. Arrow direction is confounded with required button, and timing, STOP outcomes, prior errors, response selection, and longer history may affect the comparison.

We used the nominal schedule definition: active trial types, arrow directions, and following NULL durations. It enabled equal schedule weights and removal of one schedule at a time.

- usesThe third GO contrast is 13.55 ms after adjustment for three arrow transitions in 125 ds000030 control runs.
Its within-participant overlap weights and two-transition pattern adjustment define the direct comparison. The new code gives its 15.918993158960564 ms mean and adds the earlier transition to test the paired change.
- usesThe mean third GO contrast is −1.16 ms with button pattern adjustment in 87 ds004636 v1.0.4 participants.
I used its third GO contrast, two-transition statistical weights, and two-estimate bootstrap procedure. These methods define the primary calculation on ds004636.
