摘要：The individual dynamics of the emotional component of the perception of musical melodies was studied. The indicators of emotional status were involuntary reactions of the summary skin potential (SSP) and arbitrary clicks by subjects on the “like” or “dislike” buttons while listening to melodies. The frequency of arbitrary button clicks serves as an indicator of the degree of differentiation (detail) of the conscious perception of various elements of the melody. By digital processing of the SSP, its derivatives were obtained — heart rate, median frequency and the RMS amplitude of the SSP as functions of time, etc. The temporal dynamics of these indicators turned out to be more intense compared to the frequency of pressing, which is explained by the specificity of the interaction between conscious and unconscious levels of perceptions. In connection with the use of several indicators of continuous emotional dynamics, there is a need for their integral representation. An example of such integration is given for two indicators in the form of individual approximating ellipses. In the future, it is planned to use modern computer graphics to solve the problem.
