The DMCC project is committed to the incorporation of current best practices to maximize the transparency, reproducibility, and ease of dissemination of project tools and findings. Please explore the following links to access released data sets, DMCC55B and DMCC13benchmark.
DMCC55B
Dataset Description: The DMCC55B dataset has 55 healthy unrelated young adult participants. Each performed four well-established cognitive control tasks (Stroop, AX-CPT, Cued Task-Switching, and Sternberg Working Memory) while undergoing moderately high-resolution functional MRI scanning. The dataset includes a range of state and trait self-report questionnaires, as well as behavioral tasks assessing individual differences in cognitive ability. The DMCC project is on-going and features additional components (e.g., related participants, manipulations of cognitive control mode, resting state fMRI, longitudinal testing) that will be publicly released following study completion. This DMCC55B subset is released early with the aim of encouraging wider use and greater benefit to the scientific community. The DMCC55B dataset is suitable for benchmarking and methods exploration, as well as analyses of task performance and individual differences.

DMCC13benchmark
Data set includes raw and preprocessed (fmriprep and HCP pipelines) imaging datasets for 13 DMCC participants used in some benchmarking analyses, including those described here.
DMCC13benchmark only partially overlaps with DMCC55B, even for the several participants included in both datasets: DMCC13benchmark includes resting state runs from all sessions (up to 30 minutes total), but no individual difference questionnaire responses.
