Zero recorded delays coincide with early responses and shift SSRT arithmetic in ds000030 controls
In OpenNeuro ds000030 snapshot 1.0.0, 274 of 4,032 STOP trials (6.80%), from 84 of 126 selected control participants, have a recorded StopSignalDelay of zero, a positive LadderTime, and a response before that staircase time. Every such event is labelled UnsuccessfulStop and has a nonzero button code. With other integration choices fixed, replacing each recorded zero with that trial’s LadderTime lowers the arithmetic estimate by a mean 30.06 ms (participant bootstrap 95% interval 23.56–37.02 ms). The corresponding mean estimates are 225.18 ms using recorded delays and 195.12 ms in this hybrid sensitivity analysis. These are field-definition and arithmetic observations. The audit did not measure tone onset, validate the hybrid as a correction, establish true SSRT, or challenge prior neural findings. It covers one snapshot and one availability-defined control cohort. Physical cue timing and the exact deployed task and conversion code remain unknown.

- A second calculation gives the reported delay results for 126 ds000030 control runs.
[Legacy relation: reproduces] A separate calculation reproduces the 126-control trial counts, participant estimates, 124-control basic screen, delay transitions, and both bootstrap intervals. Fresh pinned data match all source hashes. The original-code replay also gives six identical outputs.
- Shared ds000030 stop-signal files show that screening and delay conventions explain summary differences
[Legacy relation: reproduces] Used its pinned control files, source manifest and authenticated subject outputs to recompute 2,772 specified nonempty metric/eligibility comparisons, its 126-control means and 124-control basic screen. Fresh version-source bytes match. Does not reproduce bootstrap intervals, figures, staircase analyses, acoustic timing or biological validity.
