Poster Presentations

Over the course of three days, “The Mind of the Chimpanzee” conference will feature the most comprehensive collection of chimpanzee cognition research in the world. The  term “cognition research” in this case refers to a broad scope of inquiry into the way chimpanzees view their world and process information, both in captive and field settings. 

During the evening of Saturday, March 24, 2007, conference delegates will have the opportunity to view a wide range of scientific presentations in poster format.  Presenters will be available for discussion of their findings and cocktails will be served from 5:30pm-7:00pm.

The following posters will be available for viewing:
