Auditory attention is a very important basic cognitive ability in the current multimediaera, and it is also the core of speech recognition and music listening functions. Based on the extendedconstruction theory of positive emotion, this study combed and analyzed the influence of music emotionon auditory attention processing. The main findings were: (1) Positive music emotion can expand thescope of attention processing, promote the flexibility of thinking, and generally reduce the inhibition ofnegative information; (2) When positive musical emotions are aroused, the processing mode of individualauditory attention is generally bottom-up, which is manifested as more dispersed attention. Future studiescan focus on the differences between music emotion and auditory attention processing of individualswith different personality traits on the one hand, and the differences in brain responses of the effects ofdifferent music emotion titers on auditory attention on the other hand, so as to promote the developmentof music in the fields of mental health, cognitive processing and even artificial intelligence while assistingthe research on the basic theory of music psychology.
