SynopsisFourteen chronic male schizophrenic patients and six male control subjects were com pared in an escape paradigm involving temporal warning of the presentation of an aversive tone stimulus to which an escape response was to be made. The characteristic heart rate deceleration shown immediately prior to the aversive stimulus by control subjects was absent in the schizophrenic group. Further features of this novel test paradigm distinguished the control and schizophrenic groups. This psychophysiological test procedure may be fruitful for schizophrenia research.
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.
