SSRT rank agreement is lower with recorded delays in two splits of 102 ds000030 controls
In 102 screened controls from OpenNeuro ds000030 release R1.0.5, participant stop-signal reaction time (SSRT) rank agreement was lower with recorded delays than with nominal delays in two splits of one scanner run. Spearman correlations were 0.335497 versus 0.534682 for the temporal split and 0.380959 versus 0.713001 for the interleaved split. Paired participant-bootstrap 95% intervals for recorded-minus-nominal correlation were [-0.390010, -0.025818] and [-0.518646, -0.163996]. The hybrid rule, which replaces recorded zero delays with nominal values, had correlations close to nominal. Each half had 16 STOP trials. Temporal halves differed in task behavior, and adaptive staircases link trials across halves. The analysis does not establish that any delay rule measures true stopping time, and it does not test independent sessions or full-run test-retest reliability.

Used its hash-pinned 126-control event tables, source URLs and manifests, 102-person full-run screen, three delay rules, and participant reference table. These enabled 1,386 executed whole-run value comparisons and the new fixed-cohort disjoint-half analysis. All 129 source files were subsequently read from their public URLs and verified. No fetched analysis code was run. This relation concerns computational inputs and definitions, not verified acoustic timing.

- Recorded delays give lower rank agreement in 9,995 complete random splits of 102 ds000030 control runs.
[Legacy relation: reproduces] A new calculation gives the same full-run and half-run table fields and all 12 reported Spearman point values. It uses the same 102-person screen and original split rules. It passes 12,738 reference checks at tolerance 1e-8. It does not reproduce the original bootstrap random stream. New whole staircase and random splits extend the tested scope.
- usesThe zero-entry contribution increases mean squared SSRT differences in four splits of 102 ds000030 controls.
Used its source hashes, 102-control screen, temporal and interleaved split rules, and reference score tables. Fresh source files and new code enabled the mean squared half-difference component calculation. The relation does not assert acoustic validity.
- usesPooled and delay-cell rejection rates varied across four simulated stop-signal models
Its pinned R1.0.5 source manifest supplied the 126 CONTROL event paths, source hashes, and source selection. All source bytes were downloaded again. Its analysis code and split-rank results were not reused.
- usesDisjoint GO and STOP inputs give an SSRT correlation difference of 0.229 in 125 ds000030 control runs.
We used its temporal and within-staircase alternating trial partition rules. These rules supplied disjoint 48 GO and 16 STOP inputs per half. We calculated a different endpoint: SSRT correlation with the other half GO time.
