Although there has been much speculation about psychopaths' distinctive use
of speech, to date there have been no published data documenting that psyc
hopaths communicate any differently than others. This study examined the cl
inical observation that psychopathic speech is poorly integrated compared t
o that of controls. 39 inmates from a Wisconsin state penitentiary were ask
ed to produce two stories. Cohesion analysis was used to measure how well i
ntegrated the narratives were. As predicted by Williamson [Williamson, S. E
, (1991), Cohesion and coherence in the speech of psychopathic criminals. U
npublished Ph.D. Thesis, University of British Colomhia.], psychopathy was
associated with a tendency to use fewer cohesive ties per clause. Contrary
to the Williamson (1991) predictions, however, psychopaths did not use more
incompetent references than controls. Despite its limitations, this study
provides a foundation for future work elucidating psychopathic speech. (C)
