BackgroundEmotion recognition is essential to the social adjustment and social interaction of people with intellectual and developmental disabilities (IDDs). Given that music is a medium for expressing and conveying human emotion, we conducted this preliminary study to identify musical passages representing the basic human emotions of happiness, sadness, and anger, with the goal of developing a music-based emotion perception scale for IDDs.MethodsTo identify musical passages for emotion perception, 20 certified music therapists evaluated 100 selected musical passages and established 60 pieces that yielded the highest agreement for each emotion category. During the second phase of this study, 300 neurotypical participants rated 60 passages in terms of the perceived type and intensity of emotions expressed.ResultsThe 60 passages showed high reliability and were statistically classified into three factors: happiness, sadness, and anger. The k-means cluster analysis yielded a cut-off score of 41 for the low emotion perception group (F = 1120.63, P < 0.001). The hierarchical logistic regression analysis revealed that only model 3 (musical passages) was significantly associated with low emotion perception (step χ² = 227.8, P < 0.001).ConclusionThe selected musical passages demonstrated high reliability and established three factors for identifying perceptions of happiness, sadness, and anger. Neither psychological status nor individual demographic characteristics affected the emotion perception results.© 2023 The Korean Academy of Medical Sciences.
