An arrow group fails the mean response time check in 17 of 124 ds000030 control runs that pass the pooled screen.
Among 124 OpenNeuro ds000030 control runs that passed a pooled response-time screen, 17 failed the mean-time check in one arrow group: 10 for LEFT arrows and 7 for RIGHT arrows, with no overlap. This count falls within the central 95% range (9–20) from each of two random-partition methods. Across 126 selected runs, 18 had a failure in either arrow group. Participant-level RIGHT-minus-LEFT mean-time differences were descriptive and their bootstrap intervals included zero for failed-STOP time and the mean-time gap. These results test whether a pooled screen also passes by arrow group; they do not establish an arrow-specific cause or a race-model violation. The analysis uses the recorded trial data and the target report’s cohort and screen, retains its stated exclusions and limitations, and does not assess physical sound onset or neural outcomes.

Its source manifest specified the exact 130 public files and hashes. Its pooled table supplied 1,008 comparison values and flags. This enabled the same 124-run screen cohort and a source-data comparison before the arrow-group check.
