Emotional assessment of auditory stimuli of different intensity
(RESUME)

Subjects with strong and weak nervous systems were to provide verbal emotional assessment (of the type: indifferent, pleasant, unpleasant, very unpleasant, unbearable, painful) of auditory stimuli of different intensivity in combination with arranging them on a quantitative (numerical) scale. Results of the study prove the hypothesis that in persons with strong nervous system arousal provoked by strong stimulation is higher and reaches therefore the pain and discomfort thresholds earlier as compared with persons with weak nervous system.
