Abstract
-
In an investigation of auditory temporal integration, right and left ear thresholds to brief and long (2 and 500 ms) 1000 Hz pure tone or white noise stimuli were obtained for 19 psychiatric patients and 10 matched non-patient controls. Clinical evaluations were made with the aid of tape recorded Combined Instrument Schedule/Multiple Diagnostic Strategy Schedule (CIS/MDSS) interviews. The patients were given project diagnoses of schizophrenic or affective psychotic disorder, based on agreement by several well-trained diagnosticians. Symptom profiles based on Cross-National Study norms were also scored by three well-trained raters.;The reliability and validity of psychiatric diagnoses vs. symptom profiles were contrasted for utility in a research setting. Relationships between drug dosage, symptomatology and auditory threshold measures were evaluated. Relationships between within-session auditory threshold variability, symptomatology, and threshold level were also examined. In addition, piloting was performed on two non-patient subjects, to determine the characteristics of auditory temporal integration functions at the parameters used in present study.;The brief and long auditory stimuli were used to assess the relative efficiency of brief and long time constant auditory processing. A duration effect measure of auditory processing (the difference in thresholds to brief and long stimuli) was used to reflect auditory temporal integration.;Affective patients were found to have higher 2 ms click thresholds and steeper-sloped temporal integration functions than those of the control subjects. This replicated earlier work by Bruder and his colleagues (1979; 1976; 1980). These higher thresholds were found to be highly correlated with the presence of speech retardation, flat affect, and bizarre behavior in this group. Higher click threshold (steeper-sloped temporal integration) was also found to be related to the presence of auditory hallucinations in the affective patients. Auditory hallucinations were not found to be correlated with the speech retardation, flat affect, and bizarre behavior symptom cluster in any of the subject groups; however all of these symptom factors do have a high language loading.;These findings, which suggest a deficit in short time constant auditory processing in affective patients with linguistically loaded symptomatology, stand in contrast to those of Bazhin, Wasserman, and Tonkonogii (1975) and Babkoff, Sutton, Zubin & Har-Even (in press). It was the hallucinating affective, and not the schizophrenic group, that showed significantly higher brief thresholds and steeper-sloped temporal integration in the present study.
