This stujly examined paranoid and nonparanoid schizophrenic performance on a battery of information processing measures spanning precategorical processing, short-tei|m memory, and long-term memory. Multivariate analyses of the multiple processing indexes revealed two performance dimensions. The first represented "processing efficiency" maximally separating the paranoids and nonpatients, with the nonparanoids falling in between. The second dimension reflected a response style of "propensity toward stating the presence of stimuli or stimulus properties," with the most extreme separation occurring between the paranoids (higher propensity) and nonparanoids. Though closer to the paranoids, the nonpatients fell between the two schizophrenic groups. Discussion draws on the bidimensional characterization of the paranoids and nonparanoids, as well as on their differential performance on individual measures.
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.
