Musical Advantage in Lexical Tone Perception Hinges on Musical Instrument

Abstract

Different musical instruments have different pitch processing demands. However, correlational studies have seldom considered the role of musical instruments in music-to-language transfer. Addressing this research gap could contribute to a nuanced understanding of music-to-language transfer. To this end, we investigated whether pitched musicians had a unique musical advantage in lexical tone perception relative to unpitched musicians and nonmusicians. Specifically, we compared Cantonese pitched musicians, unpitched musicians, and nonmusicians on Thai tone discrimination and sequence recall. In the Thai tone discrimination task, the pitched musicians outperformed the unpitched musicians and the nonmusicians. Moreover, the unpitched musicians and the nonmusicians performed similarly. In the Thai tone sequence recall task, both pitched and unpitched musicians recalled level tone sequences more accurately than the nonmusicians, but the pitched musicians showed the largest musical advantage. However, the three groups recalled contour tone sequences with similar accuracy. Collectively, the pitched musicians had a unique musical advantage in lexical tone discrimination and the largest musical advantage in level tone sequence recall. From a theoretical perspective, this study offers correlational evidence for the Precision element of the OPERA hypothesis. The choice of musical instrumental may matter for music-to-language transfer in lexical tone discrimination and level tone sequence recall.
