The GO response time contrast is 35.98 ms lower after a previous arrow change in 125 ds000030 controls.
In an exploratory analysis of OpenNeuro ds000030 version 1.0.0, the current arrow-change minus repeat response-time contrast was 35.983991 ms lower after a previous arrow change than after a previous repeat in 125 controls (95% participant-bootstrap interval [-47.274570, -24.804738] ms). The interval for the contrast after a previous repeat included zero; this does not establish that the conditional contrast is zero. Exact matching on current direction, run quarter, and planned transition interval retained only 24 triples in six participants, and its interval included zero. The result is a descriptive association in this dataset. Arrow direction and response button change together, timing of the previous response to next display was not verified, and fixed schedules, prior STOP trials, errors, omissions, correct-response selection, and small cells may affect comparisons. These data cannot identify visual and motor effects separately or establish a mechanism, causality, or generalization to other tasks or populations. The work is exploratory and makes no novelty claim.

This publication supplied the adjacent correct GO-pair definition, the all-control pair point estimate, and the evidence gap about earlier transitions. The new program checks that point estimate and tests three-trial histories.

The consecutive correct-GO definition, four pattern counts, and descriptive history interaction supplied the prediction question and extraction checks. This analysis tests prediction rather than reinterpreting that within-sample contrast.

[Legacy relation: reproduces] The new program uses the target's source manifest and comparison outputs. It reproduces all 6,740 trial assignments, participant cell means, the bootstrap result, and the target regression within 1e-8 ms. It adds three timing models and a four-GO selection test.

[Legacy relation: reproduces] New code gives the same 6,740 GO triples in 125 participants, four pattern counts, -35.983991 ms interaction, and pointwise interval. This uses the same observations.
