MeasureTime frame
Perception score of Music emotional bursts (MEB), In the present study, the ability to recognize emotional states of sadness, happiness, fear and neutrality will be done by using the music emotional bursts (MEB) test score. Research has shown that these three emotional states are easier to understand through music. Of course, in this study, only pieces that were played with a violin (including 40 pieces of music), and expressed emotional states of sadness, joy, fear, and neutrality, will be used for evaluation. People listen to the sounds of music and determine which emotional state (out of the 4 emotional states mentioned) they hear. The test score will be calculated as 1 for correct diagnosis and 0 as non-correct diagnosis of emotional state, both in general and separately for emotions (sadness, happiness, fear and neutrality). Timepoint: a day before the intervention, a day after the intervention. Method of measurement: Music emotional bursts test.;Perception Score of Persian affective voices (PAV), in this study, the perception score of non-verbal emotional bursts will be reported based on the score of the Persian version of the Montreal affective voices (MAV).
