The third GO contrast is 13.55 ms after adjustment for three arrow transitions in 125 ds000030 control runs.
In 125 control runs from OpenNeuro ds000030, the mean third GO reaction-time contrast remained positive after adjustment for three consecutive arrow transitions: 13.547 ms (simultaneous 95% interval 5.795 to 21.300 ms). The paired change from the earlier two-transition adjustment was -2.372 ms (simultaneous 95% interval -5.416 to 0.673 ms), which includes zero. The estimate uses observed within-pattern overlap, with unequal pattern contributions across participants; only 12 participants had all 16 pattern-history cells. The result is exploratory, applies to these observations and schedules, and does not establish a cause. Arrow identity and required button identity coincide in this task, and several history and timing factors remain possible influences.

Its nominal schedule definition uses active trial type, arrow, and following NULL duration. This definition supplies the groups for equal schedule weights and removal of one schedule at a time. No prediction result is reproduced.

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.
