Electrodermal Nonresponding in First-Episode Psychosis as a Function of Stimulus Significance

Abstract

reviewed the literature on electrodermal nonresponding (EDNR) in schizophrenia and the mood disorders / because the signal value or meaningfulness of stimuli may differentially affect the likelihood of observing EDNR in individuals with these types of disorders, we have paid special attention to how nonresponding in these diagnostic groups varies with stimulus meaningfulness (from the chapter) presented the results of a large-scale investigation of EDNR in first-episode psychotic patients with these disorders / [showed] that although EDNR may be common among psychotic individuals, it may have special significance when it appears in schizophrenic patients because it is only in these patients that EDNR appears to be associated with being born during the winter (PsycINFO Database Record (c) 2007 APA, all rights reserved)
