Under fixed rules, mean response time has higher correlation between runs than cue cost in 61 children from ds005899 1.0.2

We tested two task scores in all 61 children from OpenNeuro ds005899 version 1.0.2. Mean response time was (C+U)/2. Stop expectancy cost was U-C. C and U were certain and uncertain go response means. We used correct responses from 150 to 1500 ms and the two source-mapped runs. We removed each source group mean from each score and run. Correlations were 0.890 for mean response time and 0.385 for cost. The paired difference was 0.504, with an approximate 95% bootstrap interval from 0.195 to 0.883. All seven fixed checks had positive difference intervals. The package preserves 129 source files, a 9,920-row trial table, code, all resample indices, and repeat instructions. Independent calculations passed. A fresh full repeat matched 15 numerical files and four figure files exactly. The result assumes independent children, correct source labels, and the stated score rules. It concerns two runs in this sample.
