Music expertise is known to be beneficial for cognitive function and development. In this study, we conducted 1-year music training for school children in China. The children were assigned to music or second-language after-class training groups. A passive control group was included. We aimed to investigate whether music training could facilitate working memory development compared to second-language training and no training. Before and after the training, auditory WM was measured via a digit span task, together with the vocabulary and block (...) tests of the Wechsler Intelligence Scale for Child IV. The results of the DS task revealed superior development in the music group compared to the other groups. However, further analysis of DS forward and backward tasks indicated that the performance of the three training/non-training groups only differed significantly in DS backward scores, but not in the DS forward scores. We conclude that music training may benefit the central executive system of WM, as reflected by the DS backward task. (shrink)

In this chapter we present a new approach to research in music perception allowing one to investigate how musical sound representations are formed in the human brain. By studying subjects' brain responses to unattended stimuli we can determine, for instance, whether neural circuits are more readily activated by musical sounds implicitly learned than by unfamiliar sounds even in non-musicians. Indeed, neuronal populations seem to respond more efficiently to pitch deviations within sound patterns following the rules of Western scale structure, rather (...) than to deviations inside patterns artificially created. Moreover, neural circuits are selectively activated by mistunings inside tonal melodies or by out-of-key chords inside harmonic cadences even when attention is not directed towards the sounds. These data together suggest that incoming sounds are more efficiently processed when they match the neural templates derived from our musical culture. The existence of 'musical memories' in the auditory cortex that are effortlessly activated enabling us, e.g., to identify and recognize speech vs. music sounds can thus be postulated. (shrink)
