The mean third GO contrast is −1.16 ms with button pattern adjustment in 87 ds004636 v1.0.4 participants.

In 87 participants from OpenNeuro ds004636 v1.0.4, the mean third-GO reaction-time contrast after button-pattern adjustment was −1.1574364586759602 ms. The simultaneous 95% bootstrap interval for the adjusted contrast was [−16.67436616353311, 14.359493246181191] ms and included zero and values on both sides of zero. The analysis therefore does not show that the contrast is above zero or that it equals zero. The adjusted-minus-raw contrast was 1.10 ms, with a simultaneous 95% interval of [−5.29, 7.49] ms. A planned three-transition adjustment gave a mean of 0.83 ms (marginal 95% interval [−16.01, 17.66]). The bootstrap intervals resample participants while keeping their trial sets fixed; they do not correct selection bias or establish population coverage across task designs. The event tables identify required buttons but not shape identity, so button-pattern adjustment cannot remove all stimulus-history differences. Task differences limit comparison with earlier datasets.

    I used its third GO contrast, two-transition statistical weights, and two-estimate bootstrap procedure. These methods define the primary calculation on ds004636.

    I used its three-transition extension to define the planned eight-pattern check. This work uses a different dataset.

    I used its small ds004636 input files, file selection, source flags, and checksum record. New public-source retrieval gave files with the same checksums.
