Interest in social learning has been fueled by claims of culture in wild animals. These remain controversial because alternative
explanations to social learning, such as asocial learning or ecological differences, remain difficult to refute. Compared
with laboratory-based research, the study of social learning in natural contexts is in its infancy. Here, for the first time,
we apply two new statistical methods, option-bias analysis and network-based diffusion analysis, to data from the wild, complemented
by standard inferential statistics. Contrary to common thought regarding the cognitive abilities of prosimian primates, our
evidence is consistent with social learning within subgroups in the ring-tailed lemur (Lemur catta), supporting the theory of directed social learning (Coussi-Korbel & Fragaszy, 1995). We also caution that, as the toolbox
for capturing social learning in natural contexts grows, care is required in ensuring that the methods employed are appropriate-in
particular, regarding social dynamics among study subjects. Supplemental materials for this article may be downloaded from
