Delay-field choice changes participant ranks and GO-speed associations in 126 ds000030 control runs
In 126 public control scanner runs from OpenNeuro ds000030, calculating integration-method stop-signal reaction time (SSRT) with recorded rather than planned stop delay reversed 1,466 of 7,875 participant pairs (18.62%). The Spearman association with mean responding GO reaction time changed from 0.01805 for planned delay to 0.25083 for recorded delay; the paired difference was 0.23277 (participant-bootstrap 95% interval 0.12695 to 0.33688). A filled-delay diagnostic had 46 pair reversals against planned delay. The comparison holds the cohort, responses, and estimator fixed. It shows sensitivity to delay-field choice in these data. It does not identify acoustic cue onset, a true stopping time, causal inhibition-speed coupling, population independence, or test-retest reliability. Each run contains 32 STOP trials, and acquisition/converter versions and acoustic logs are unverified.

Its read all-266 scanner audit reported screened rank disagreement, motivating this control-only extension that counts exact pair reversals and paired changes in a GO-speed association; its cohort and screen are not claimed replicated.

I used its source URLs, hashes, 126-run selection, SSRT method, and person-level numeric reference. These inputs permit a checked comparison with disjoint GO trial sets. New code gives the same full-run values.
