      Brief Report

      Psychosis, Psychopathy, and Homicide: A Preliminary Neuropsychological Inquiry

      Paul G. Nestor, Ph.D., Matthew Kimble, Ph.D., Ileana Berman, M.D., and Joel
      Haycock, Ph.D.

      OBJECTIVE: This study attempted to statistically distinguish subgroups of
      murderers with mental disorders from among 26 hospitalized men (mean age=34
      years) who were committed to a maximum security forensic hospital. METHOD:
      Measures consisted of objective ratings of psychosis and psychopathy and
      neuropsychological tests of intelligence, memory and attention, executive
      functions, and academic abilities. RESULTS: Cluster analysis produced two
      distinct subgroups: one defined by high incidence of psychosis and low level of
      psychopathy and one by low incidence of psychosis and high level of
      psychopathy, each corresponding to distinct neuropsychological differences in
      intellectual abilities, learning disabilities, and social intelligence.
      CONCLUSIONS: In light of this relatively small, highly select group, these
      novel findings must be viewed as preliminary. Studies of larger cohorts are
      needed before definitive conclusions can be drawn as to the reliability of
      these two distinct symptom clusters, each independently validated by
      neuropsychological measures of intelligence, sociality, and academic abilities
