With fixed trial rules, mean response time has a higher flanker–Stroop correlation than adjusted slowing after errors in 136 selected ds004602 1.0.3 participants

We compared behavior scores between flanker and Stroop tasks in OpenNeuro ds004602 version 1.0.3. Fixed trial rules selected 136 people. The Pearson correlation between tasks was 0.701 for mean correct response time and 0.242 for adjusted slowing after errors. The paired difference was 0.458, with a 95% person bootstrap interval of 0.261 to 0.648 from 20,000 draws. All nine planned check comparisons retained a positive difference. In 125 selected people, the slowing score also had lower correlations between task halves. The package preserves 363 event files, seven source metadata files, three source MATLAB files, 152,453 trial records, code, and bootstrap draws. A separate parser, score calculation, complete offline repeat, and fresh downloads checked the results. The result assumes correct event labels and times. It applies to selected observed behavior scores and does not identify a latent brain trait correlation.
