Theory and previous research using the inkblot body image indexes developed by Fisher and Cleveland indicated that it should be possible to alter perceived boundary defmiteness in schizophrenics by making them aware of their own .bodies. Somatic awareness was induced in four different groups of hospitalized schizophrenics through a variety of means. Highly significant increases in the Barrier score from pretest to posttest were achieved by all groups which experienced actual physical stimulation, supporting the basic hypothesis. The Penetration score for these groups, however, was only slightly affected by the experimental manipulations. An imagination condition failed to produce significant changes in either boundary index.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
