Four GO time limits change group coefficients by less than 2.5 ms in 124 ds000030 participants.

We examined whether removing very short correct GO response times changed diagnosis group coefficients in the OpenNeuro ds000030 version 1.0.0 stop-signal task data. The analysis used 124 participants in 13 schedules that included all four diagnosis groups, and fit schedule, diagnosis, age, and gender terms. We removed times below 100, 150, 200, and 250 ms, keeping values at each limit. The largest absolute coefficient change was 2.418127651583288 ms, for BIPOLAR at 150 and 200 ms; those limits gave the same result because no accepted time fell between them. All 12 Bonferroni family 95% intervals for changes contained zero, and some intervals included absolute changes greater than 2.5 ms. The results describe this data release, model, and common-schedule sample. They do not identify guesses or recording errors, establish a causal diagnosis effect, or validate stopping-time measures. The source ReactionTime unit and event conversion remain assumptions. Errors may be dependent within schedules, which can affect the intervals.
