Abstract
The purpose of this study was to test the hypothesis that the sedation threshold is correlated with a personality factor, similar to Eysenck''s introversion-extra -version dimension or, in neurotics, a hysterical-obsessional continuum. In one part of the study, 2 psychiatrists independently rated 308 case records for hysterical-obsessional tendency. Their ratings were significantly correlated with the sedation threshold, a high threshold being associated with obsessional tendencies and a low one with hysterical tendencies. Another investigative method used was to correlate the sedation threshold with questionnaire scores of introversion-extra -version (Guilford R and S scales) in 36 neurotic patients and with ease of conditioned eyeblink formation. The threshold was significantly correlated with questionnaire scores in the predicted direction, high thresholds being associated with introversion. The threshold was not significantly correlated with conditionability, although high introversion on the questionnaire was associated with greater condition-ability. The main conclusion reached was that there is an objectively demonstrable neurophysiologica basis for the introversion-extraversion dimension.
