Socially-biased learning is widespread in the animal kingdom and important
in behavioral biology and in evolution. However, common misconceptions abou
t socially-biased learning stand in the way of its effective study by psych
ologists. Our aim in this paper is to recruit psychologists' interest in so
cially-biased learning by (1) defining this domain, and distinguishing it f
rom imitation, (2) explaining the significance of socially-biased learning
in behavioral evolution, (3) recommending comparative methods to analyze so
cially-biased learning in natural settings. Linked examination of the varyi
ng social contexts of practice and the forms and rate of change in individu
al practice can indicate the extent to which social context accounts for di
fferences in learning. We close with a model of how social bias might modul
ate learning, and suggest ways of testing this model.
