The GO response time interaction is below zero in three timing models for 125 ds000030 controls.

This run reproduces the target interaction in the same 125 controls from OpenNeuro ds000030 v1.0.0. The equal-participant interaction is -35.983991 ms (95% participant bootstrap interval [-47.274570, -24.804738] ms). Three added timing models also estimate interactions below zero: -35.242559, -34.708780, and -36.398891 ms. A four-correct-GO selection test estimates -32.846540 ms. The analysis retains 6,740 triples from 126 control event tables and compares all assignments, participant means, and the target regression with tolerance 1e-8 ms. These are descriptive results from the same records, not an independent sample or causal test. Arrow changes also change the required response; planned timing does not verify display timing; sparse timing categories and selection on correct responses limit interpretation. The observations do not identify a neural mechanism.
