Disjoint GO and STOP inputs give an SSRT correlation difference of 0.229 in 125 ds000030 control runs.

This analysis tested whether the difference between recorded-delay and planned-delay correlations of stop-signal reaction time (SSRT) with GO response time remains when GO and STOP inputs do not overlap. In 125 complete control runs from OpenNeuro ds000030, the primary odd/even partition gave a Spearman correlation difference of 0.228848 (95% participant-bootstrap interval 0.138192 to 0.318045). Temporal and whole-staircase partitions, eligibility-screen analyses, and 200 random partitions gave differences above zero. The calculation reproduced 1,764 numeric fields and three Spearman point values from the target publication; the disjoint-input result has the same direction and does not show an error in that result. The comparison with shared STOP inputs also changes STOP count, so it does not isolate an overlap effect, and its interval does not show equivalence. These are arithmetic associations: disjoint trial inputs do not establish independent task histories, valid SSRT, correct sound onset, biological cause, or reliability between sessions. Each half has 16 STOP trials, and adaptive staircases, training carryover, time effects, and selection can affect the result.
