Training and scanner SSRT have a positive partial correlation in 107 ds000030 pairs
In 107 CONTROL participant pairs from OpenNeuro ds000030 version 1.0.0, training and scanner stop-signal reaction time (SSRT) scores had a partial correlation of 0.569498 after linear adjustment for the mean of the two scanner starting delays (95% participant-bootstrap interval 0.424589–0.703082). The scores are arithmetic estimates in milliseconds, not direct measurements of biological stopping time. The positive association was similar across three recorded-delay definitions and two larger samples. These descriptive results do not establish independence between sessions, a causal effect of delay transfer, or the result of an independent delay reset. Each run had 32 STOP trials; the analysis does not measure trial uncertainty, timing error, screen-selection uncertainty, or regression validity.

Its inspected source manifest, exact 107/118/126 pair selections, score definitions, run table, and raw correlation outputs define this extension. All 260 source files were retrieved anew and hash-verified. New code matches every run-table cell, sample identifier, and raw correlation, then calculates partial correlations. Its full staircase-transition audit is outside this calculation.

- usesStarting delay reduces scheduled SSRT leave-one-out mean squared error by 7.28% in 107 screened ds000030 control pairs.
Its mean starting-delay adjustment and distinction between arithmetic covariance terms and regression motivate the combined training-score and starting-delay model. This run fits that model inside participant holdouts and adds prediction intervals. It does not repeat the partial-correlation bootstrap or test a delay reset.

Its mean scanner starting-delay regression definition and interpretation limits give the adjustment for this 232-pair sensitivity calculation. This work does not reproduce its 107-control sample or bootstrap interval.
