Our research uses a troup of 30 baboons maintained in a large (700m2) compound. The main originality our research facility is that the members of the group have a free access to a series of operant conditioning test systems, equiped with touch screens, adjacent to the compound. The baboons isolate themseves from the group to participate to the research program on a voluntary basis. This facility is unique in its concept and scale. It allows research programs on both the social and nonsocial aspects of cognition, while meeting the most stringent ethical standards in animal research.
