Social Learning Strategies And Predation Risk, Proc. Biol. Sc.
 









Excerpt: Animals can acquire information from the environment privately, by
sampling it directly, or socially, through learning from others. Generally,
private information is more accurate, but expensive to acquire, while social
information is cheaper but less reliable. Accordingly, the ‘costly information
hypothesis' predicts that individuals will use private information when the
costs associated with doing so are low, but that they should increasingly use
social information as the costs of using private information rise. While
consistent with considerable data, this theory has yet to be directly tested in
a satisfactory manner. We tested this hypothesis by giving minnows (Phoxinus
phoxinus) a choice (...).
