The visit agreement gap between mean and contrast times was uncertain in 54 ds005012 v1.0.3 participants with at least five successes per condition and visit

We tested two behavior scores from the public monetary incentive delay task in OpenNeuro ds005012 version 1.0.3. The scores use stored successful responses for large gain and no money at stake. The main sample has 54 participants with at least five successes per tested condition and visit. The median visit interval is 390.5 days. The absolute agreement ICC was 0.133 for the mean score and 0.021 for the incentive contrast. The gap was 0.112. Its 95% paired participant bootstrap interval was -0.193 to 0.432. Thus, the main test did not establish higher agreement of the mean score or equal agreement. Positive group contrasts of about 8 milliseconds coexisted with very low estimated agreement of individual contrast scores. Mean response times and deadlines were about 50 milliseconds shorter at visit 2. The data do not identify the cause. Six checks were specified in the local plan. The deadline ratio check had a gap interval above zero. It changes the score meaning and does not replace the main test. A separate parser and covariance calculation passed. A fresh source download reproduced all 18 main output files exactly. The package preserves source files, hashes, code, scores, all resampling indices, results, figures, and instructions. It does not test neural signals or recover response times on failed trials.
