Fig. 2.

Responses in the ERT (Emotional Recall Task) visualized as experiential co-occurrence networks. Each node represents an emotion word reported in the ERT. Node size is proportional to number of people reporting the given emotion. Color denotes the valence of emotion on a continuous scale from negative (red) to positive (blue). The edges connecting two nodes are weighted by the proportion of participants who reported both emotions. To ensure readability, we present only those emotions reported by at least 4% of a sample in each wave. The four most frequently reported emotions are shown below each network, along with the proportions of participants reporting them. Cumulative numbers of infections on the first date of data collection in each wave are shown in the yellow boxes.
