Effect of musical experience on learning lexical tone categories.

Previous studies suggest that musicians show an advantage in processing and encoding foreign-language lexical tones. The current experiments examined whether musical experience influences the perceptual learning of lexical tone categories. Experiment I examined whether musicians with no prior experience of tonal languages differed from nonmusicians in the perception of a lexical tone continuum. Experiment II examined whether short-term perceptual training on lexical tones altered the perception of the lexical tone continuum differentially in English-speaking musicians and nonmusicians. Results suggested that (a) musicians exhibited higher sensitivity overall to tonal changes, but perceived the lexical tone continuum in a manner similar to nonmusicians (continuously), in contrast to native Mandarin speakers (categorically); and (b) short-term perceptual training altered perception; however, there were no significant differences between the effects of training on musicians and nonmusicians.
