In the first study, 20 male and 20 female volunteers were studied under threat-of-shock and no-threat conditions with respect to anxiety levels, skin conductance, EEG auditory evoked response, and alpha-blocking variables. The threat-of-shock increased anxiety levels, skin conductance level, and fluctuations. The P300 component of the AER was greater in(More)
Habituation of the GSR responses obtained from a group of 20 patients sufferings from anxiety states was compared with a group of 20 matched normals, selected for lack of anxiety. Habituation parameter did differentiate the two groups very distinctly, where very fast habituation WP.S noted in the normals. Findings were interpreted in terms of the level of(More)
Habituation of alpha attenuation responses (AAR) obtained from a group of 20 depressed patients was compared with a group of 20 matched normal controls. The slope of the AAR habituation curve over trial showed that the normals habituated much quickly than those of patients. The findings were interpreted in terms of the level of arousal of the(More)
Physiological (Skin conductance) and Psychological (State-trait anxiety) measures of anxiety were employed to assess the level of anxiety in 10 anxious neurotics, 10 schizophrenics and 10 normal subjects. Both the Physiological and Psychological measures were sensitive in detecting the level of anxiety in normals and patients. But interrelationships between(More)
