A vocabulary of abnormal behaviors in restrictively reared chimpanzees.

The purpose of this paper is to establish a vocabulary for the systematic documentation of abnormal behavior in restrictively reared chimpanzees. Such a vocabulary facilitates communication regarding the range of behavior patterns indicative of psychopathology. The behavior of restrictively reared chimpanzees was observed and descriptive terminology is developed to aid in documentation of the range of abnormal behavior observed in restrictively reared chimpanzees. Such documentation is the first step in monitoring and evaluating a rehabilitation program.
