Failed STOP weights for four parts give a lower phase rank correlation than pooled weights in 266 ds000030 pairs.
In 266 paired participants from OpenNeuro ds000030 snapshot 00016, this analysis compared pooled, all-STOP-weighted, and failed-STOP-weighted GO-minus-failed-STOP response-time differences between training and scanner phases. With four consecutive parts, Spearman correlations were 0.3780, 0.3781, and 0.3547, respectively. The failed-STOP versus pooled correlation change was -0.0233 (paired 95% bootstrap interval [-0.0732, 0.0227]), which includes zero and does not establish a population decrease. The failed-STOP selection term had a mean below zero in both phases, but its phase rank correlation was 0.1183 (95% interval [-0.0092, 0.2457]). The analysis uses 32 STOP trials per phase, same-session phases with different context and practice, and no trial bootstrap, p-value, or multiplicity correction. The results do not establish a stable individual correction, estimate stop-signal reaction time, validate a race model, or show biological causality. Sensitivity analyses reuse the same data and are not independent replications.

We used its paired phase-comparison question and intact-participant bootstrap approach. Our RT measures and screen differ. We did not reproduce its SSRT estimates.
