Response slowing after stop signals has lower correlation between training and scanner tasks than mean go response time in 250 ds000030 v1.0.0 adults

We tested response slowing after stop signals in 250 adults from OpenNeuro ds000030 version 1.0.0. The settings were training outside MRI and task performance inside the scanner. Mean slowing was 41 milliseconds in training and 47 milliseconds in the scanner. The correlation between settings was 0.435 for slowing and 0.712 for mean correct go response time. The paired correlation difference was 0.278, with a 95 percent bootstrap interval of 0.137 to 0.430. Planned checks supported this comparison. The settings differed, so this result does not measure repeatability under identical conditions. The package preserves source files, hashes, code, participant measures, checks, and reproduction instructions. Unmapped source response codes limit the exclusion rules and generalization.
