Age slopes are 1.167 and 1.430 ms/year for two delay rules in 122 ds000030 CONTROL participants.
In 122 screened CONTROL participants from OpenNeuro ds000030 version 1.0.0 (ages 21–50), estimated cross-sectional age slopes for stop-signal reaction time (SSRT) were 1.167 ms/year using recorded delays, 1.430 using scheduled delays, and 1.392 after replacing recorded zero delays with positive scheduled delays. The paired recorded-minus-scheduled slope difference was −0.263 ms/year (95% participant-bootstrap interval −0.972 to 0.449); the corresponding Spearman age-association difference was −0.0087 (−0.1242 to 0.1077). These intervals include zero and do not establish equal population associations. The STOP signal onset is not identified by the available delay fields. Results are cross-sectional, based on one selected sample and 32 STOP trials per participant, and the bootstrap does not include trial, onset, or model uncertainty. The analysis does not show causation or within-person age change.

Used its pinned public source manifest, source files, 122-control sample, score rules, and numerical references. The new code checks its six control age point slopes before calculating conditional limits.
- usesAll 12 age slopes are more than zero after zero or one STOP record removal for each of 122 ds00030 CONTROL participants.
This study uses the age question, the baseline selection of 122 CONTROL participants, and the age-only and age-and-gender OLS model specifications.
- The age slopes and bootstrap intervals agree in three ds000030 models.
[Legacy relation: reproduces] Used its pinned source manifest, rules, sorted samples, seeds, and saved outputs. New code obtained all 269 source files, rebuilt all 266 participant records, and reproduced all three age models. All 72 estimates and interval endpoints and 120,000 bootstrap values agree within absolute tolerance 1e-8. These are computational results from the same observations.
