Electrodermal orienting response during episodes of schizophrenic illness and remissions: a case study

Abstract

SummaryThe aim of the present case study was to examine electrodermal orienting response during periods of acute illness and during remission in a male schizophrenic patient. He was exposed five times to a series of moderately intense tones in a standard orienting habituation paradigm, while skin conductance was recorded. He failed to respond to any of the first two tones and was considered a nonresponder both times when he was acutely symptomatically ill. In contrast, he responded to some of the first tones when he was under treatment and both times when he was tested in remission.
