Fig. 1

Two examples of person-specific network graphs. Circles represent variables (e.g., emotion, cognition), and lines between circles represent associations. The color of lines indicates whether an association is positive (blue) or negative (red), and their thickness and transparency indicate their relative strength. The left panel shows a contemporaneous network with undirected connections, which represent the partial associations between the two variables measured at the same time point. The right panel shows a temporal network with directed connections, which indicate that a variable at time point t-1 (origin of arrow) is partially associated with a variable at time point t (point of arrow)
