The aim of the study was to find out the extent of universality of perception of the emotional tone of information for three types of stimulus material: human behavior, music, and non-musical auditory stimuli. A distinction between two aspects of emotional tone perception was proposed: accuracy of evaluation of its modality and sensitivity to its intensity. Methods to measure these two aspects were developed for three types of stimulus material. The hypothesis was proposed that sensitivity is more universal, whereas intensity is more specific regarding the type of stimuli. Empirical evidence in support of the hypothesis was found.
