Georgia State University researchers Robert Latzman and William Hopkins recently published findings on psychopathic tendencies in chimpanzees in the journal Clinical Psychological Science. Using a chimpanzee personality measure, they identified and measured behaviors consistent with each of the three dispositional tendencies included in the triarchic model of personality for humans: disinhibition, boldness, and meanness.
The research provides a foundation for better understanding not only the nature and origin of psychopathic tendencies in humans but also, consistent with recent National Institutes of Health priorities, lays the groundwork for understanding the underlying biological basis of other clinical conditions.
