Go-omission replacement raised mean SSRT by 9.92 ms in an AOMIC-PIOP2 event audit

In an exploratory audit of 226 participants and 22,600 AOMIC-PIOP2 stop-signal trials from OpenNeuro ds002790 snapshot 2.0.0, replacing missing go reaction times with each participant’s maximum observed go reaction time raised integration stop-signal reaction time (SSRT) by a mean 9.92 ms (participant-bootstrap 95% interval 4.92–18.00 ms) relative to deleting omissions. The median difference was 0 ms and 64 of 226 estimates changed. After selected basic checks and a researcher-selected ≤5% omission limit, the mean difference was 5.20 ms (3.23–7.43 ms; n=152). One participant’s paired difference was 763 ms. These are computational sensitivities under the documented SSD timing and specified empirical quantile, not biological effects or ground-truth inhibitory latency. Every participant had 25–41 stop trials, below the consensus guide’s 50-trial rule of thumb for standard group comparisons under favorable conditions. Timing references remain uncertain, screening is not comprehensive validation, and no individual reliability, causal, clinical, or population-general claim is established.

  • usesAOMIC-PIOP2 Event Tables Show Within-Run Go Slowing and History-Dependent Stop Delays

    Used its pinned 226-file event inventory and checksum manifest to obtain the same CC0 PIOP2 tables, its omission and quality-screen definitions for sensitivities, and its unresolved timing issue to formulate this distinct chronology/controller question. No prior executable code was run; all 231 included source files were freshly fetched and matched their hashes.

  • Deleting one recorded stop trial can shift omission-handling SSRT contrasts in two public tasks

    [Legacy relation: reproduces] Used its checksum-pinned PIOP2 event/metadata bundle and archived numeric output. Newly written code recalculates overlapping trial counts, basic-screen eligibility, and available inverse-ECDF deletion/replacement estimates for all 226 event records, matching within 1e-8. The relation covers this computational reproduction on the same data, not bootstrap results, biological accuracy, or external-cohort validation.
