Multidimensional scaling (MDS) 2D projection of dFCs from three subjects with different overall task performance (A, B, and C), and clustering accuracy vs. RT for each subject during the working memory task (D). The dFCs are color coded based on the task. Rest: gray dot; memory: blue crosshair; video: yellow dot; math: green dot. (A) Subject 1 is a good subject with well distinguishable dFNC structure leading to very high overall clustering accuracy (100%). (B) Subject 22 is a mediocre performer with a few outliers leading to relatively high overall clustering accuracy (84.38%). (C) Subject 11 is a bad performer, and the lack of structure led to degraded overall clustering accuracy (53.12%). (D) Clustering accuracy was correlated with average RT for the memory task. Each cross-represented a subject.
