Abstract

The main factors that we believe account for the relative psychological health of Vilab II chimpanzees [New York Blood Center's Laboratory in Liberia] ... are: avoidance of solitary housing and rapid re-socialization and rehabilitation, a caring staff that genuinely like chimpanzees and are sensitive to their needs, and release of post-experimental chimpanzees onto free-ranging habitats [islands] in groupings that approximate the size of a normal chimpanzee troupe. Rehabilitation process allowing subsequent release [retirement] on island is clearly described.
