PRIMATOLOGICAL SYMPOSIA AT
the Seventy-First Annual Meeting of the
American Association of Physical Anthropologists
to be held at The Adam’s Mark Hotel Buffalo,New York April 10 to April 13,2002
Session 4. Primate Cognitive Ecology. Symposium. Grand Ballroom D.
Organizer and Chair:P.A.GARBER,University of Illinois,Urbana.
Compared to many groups of animals,primates are characterized by large brain size,enhanced manipulative abilities,and complex cognitive skills.In this symposium we examine primate cognitive ecology.Our goals are to examine evidence for major
taxonomic differences in primate cognition,and whether a theory that combines causal knowledge of both social and ecological
information offers a clearer understanding of decision-making and cognition in human and nonhuman primates.Emphases will
be placed on problem-solving strategies in natural field settings.Research on primate cognition in captive environments,and
studies of learning and neural development also are included.
