Uma investigação sobre os aspectos emocionais de acordes musicais em uma perspectiva analítico-comportamental

Abstract

The main objective of this thesis was to study the relationship between musical chords and the respective emotions evoked by them using the theoretical basis of Experimental Behavior Analysis. To this end, the thesis was composed of three articles. The first article was a scoping review of peer-reviewed articles published between 2005 and 2023. The keywords used were the entries Chords AND Emotions. In all, 11 articles were selected. The results indicated that all articles used self-report measures in their procedures and that the ability to relate chords to their emotions was present in most of the investigated populations. The second article was a fading-out experiment in which the emotional aspects of chords were used to teach conditional relations between chords and their respective labels. In other words, this article used the conditional relations between major chords-happy faces and minor chords-sad faces to teach the major chords-MAJOR word and the minor chords-MINOR word relations. The results indicated that 10 participants could learn this new ability. In addition, there was generalization to similar stimuli (new major and minor chords) and major and minor excerpts and progressions (untrained skill). Finally, the third article was an experiment in which the transfer of function between musical chords and abstract figures was investigated in a stimulus equivalence procedure with undergraduate students. Thirty-seven participants participated in the procedure, with 30 assigned to the Control group and 7 to the Experimental group. The results indicated that all participants in the Experimental group who performed the training steps could form equivalence classes. Furthermore, the transfer of function was verified through a semantic differential. The results indicated that the abstract figure related to major chords was classified with positive valence adjectives, and the abstract figure related to minor chords was classified with negative valence adjectives.
