90 of 243 selected ds000030 version 1.0.0 control mean reaction time checks stay satisfactory after STOP response removal with response fractions from 0.25 to 0.75.
We measured how sensitive the selected mean reaction-time check is to removing responding STOP rows from the ds000030 version 1.0.0 stop-signal task. The check was satisfactory when mean responding GO reaction time exceeded mean responding STOP reaction time. For each of 243 selected scanner and training runs, we calculated exact bounds across removal subsets while keeping at least one STOP response and requiring the response fraction to remain between 0.25 and 0.75. In 90 runs the check stayed satisfactory under every permitted removal; 72 of those required the fraction limit, and 11 checks could change after one or two removals. All nine target changes after removing recorded-zero-delay STOP rows agreed. These are static sensitivity results, not probabilities, biological conclusions, or estimates of stopping ability. The runs include repeated measurements, and the bounds do not cover GO removal, nonresponse removal, or separate arrow means.
