Figure 1 Central Lemurs Are More Likely to Learn the Task Solution The lemurs who learned (white) were highly social and had engaged in more affiliative interactions than the lemurs who did not learn (gray). Node size: outdegree; numbers: order of learning. Networks are constructed from data collected before the task learning experiment. See also Table S1.

Figure 2 Frequently Observed Lemurs Become More Central in Affiliation Networks Data shown from the frequently observed lemurs in Windmill (n = 17). Because of high inter-individual variation in the frequency of being observed, we plotted ranks instead of raw values. The most frequently observed lemur was assigned a rank of 1 (x axis). A negative change in centrality rank (y axis) indicates that the lemur became more central after the experiment. See also Table S1.
