The same GO input gives higher mean staircase score correlation in 241 ds000030 scanner records.

Using 241 OpenNeuro ds000030 scanner records, this analysis compared the mean Pearson correlation between two stop-signal staircase scores when both used the same 48 GO trials versus separate 48-trial GO sets. With 16 STOP trials per score, the same-input mean was higher under nominal, recorded, and hybrid delay rules; the contrasts were 0.045584, 0.053624, and 0.045664. Participant and schedule bootstrap intervals were positive for all three rules, and all 200 random GO partitions had positive contrasts. Results also include a 265-record sample and a 199-record part-quality sensitivity sample. The finding concerns these arithmetic scores and this dataset. It does not show accurate individual stopping times, biological causality, or which estimator is better. Bootstrap intervals depend on their stated sampling assumptions.

    Its schedule definition uses trial labels, arrow directions, and following NULL durations. This work uses that definition for the schedule bootstrap.

    Its public scanner input files and source inventory enabled this score calculation. Source hashes and four new public downloads were checked.

    Its proposed staircase-specific score parts helped select the two source staircases. Its GO timing result motivated random GO partitions.

    Its same-GO comparison changes GO count from 48 to 96. This work uses that limitation to set an equal-count comparison.
