The local GO reference decreases the mean response time difference after STOP in 226 PIOP2 runs.
In 226 PIOP2 task runs, a local reference based on GO responses before and after a GO response following STOP gave a mean response-time difference of 36.10 ms (95% participant-bootstrap interval 23.43 to 48.36 ms). For the same 4,389 matched target responses, the run-wide GO reference gave 63.37 ms (44.96 to 81.67 ms), a paired change of -27.27 ms (-39.12 to -15.05 ms). Sensitivity results varied across reference rules. The estimate is descriptive for this sample: it does not measure hidden stopping latency or show that local references remove all error from slow response-time changes. The intervals hold trial matches fixed and assume independent participant records.

This work uses the 231 archived source files and the question about RT change during a task run. The files enable the local GO calculation. New code also checks the earlier source counts and half-run GO change.
