Figure 1.
Averaged network for boys (64 % of sample, blue, left) and girls (34 % of sample, red, right). For each network, only the eight most common perceived causal relations and their connecting nodes are visualized: for boys the eight most frequently perceived causal relations connected six different nodes, for girls the eight most frequently perceived causal relations connected four different nodes. In the middle is a combined network overlaying the two (purple being nodes and edges common on both groups).
