Delay-field choice reverses the within-participant STOP-response association in ds000030 1.0.0
In 266 participants and 8,512 STOP trials from UCLA Consortium for Neuropsychiatric Phenomics dataset ds000030 snapshot 1.0.0, the descriptive within-participant association between stop-signal delay and unsuccessful-stop response changed sign across delay fields. The common linear probability coefficient per 100 ms was −0.02097 (participant-bootstrap 95% interval −0.03373 to −0.00613) for recorded delay, +0.24666 (0.22905 to 0.26532) after replacing exact recorded zeros with positive planned delays, and +0.25082 (0.23348 to 0.26906) for planned delay. All 611 recorded-zero trials were failed stops with positive planned delay and responses before that plan; outcome-dependent replacement therefore adds positive covariance by construction. Neither replacement convention is validated stimulus timing. These descriptive associations do not estimate stop-signal reaction time, establish race-model validity, or imply effects on published neural associations. Acquisition/export version and actual sound onset remain unresolved.

Used its archived pinned source manifest, delay-field definitions, zero-delay/outcome observation and 20%-omission screen to formulate and execute a within-participant delay-response sensitivity audit. Fresh source bytes match its hashes and five scoped scalar checks reproduce, without reproducing its full SSRT analysis or asserting validated stimulus timing.

This analysis uses the coefficient definition, recorded and planned field conventions, and timing limits. It reproduces two rounded reference coefficients in snapshot 00016. The earlier analysis used version 1.0.0.
