To determine if attentional factors influence the suppression of the auditory P50 in a conditioning-testing paradigm, known as the 'sensory gating' effect, we tested 10 healthy young adults in four experimental conditions. The first condition was the traditional passive conditioning-testing paradigm in which a pair of identical auditory clicks is(More)
To replicate the findings of a sensory gating deficit in schizophrenia, and to determine if normals and schizophrenics are equally affected by cognitively mediated task-relevant factors, 10 healthy and 10 schizophrenic young adults were tested in two experimental conditions. In the first condition a pair of identical auditory clicks (conditioning stimulus(More)
The present study examined the effects of pre-exposure of an irrelevant stimulus on reaction time and the contingent negative variation (CNV) in healthy controls and schizophrenic patients. In Phase I, subjects were either pre-exposed (PE) or not pre-exposed (NPE) to repeated presentations of an auditory probe stimulus (white noise), while engaged in(More)
This experiment examined the hypothesis that schizophrenics are less able than normals to make use of information concerning self movement when performing auditory localization tasks, and, therefore apply an alternative localization strategy, probably involving use of the pinnae. In this study three groups (healthy controls, schizophreniform patients and(More)
