Can musical aptitude and experience predict success in non-native tone word learning?

Abstract

Non-native linguistic pitch perception is subject to influence from a variety of factors in addition to linguistic background, including musical experience. The present study investigated the effects of musical aptitude and musical experience on Cantonese tone word learning and how these musical factors interact with linguistic experience. Adult native Thai listeners whose native language (L1) is tonal and English listeners with a non-tonal L1, subdivided into musician and non-musician groups, engaged in a seven-session perceptual training program, learning the meanings of 15 novel vocabulary words distinguished by five Cantonese lexical tones. Before training, a musical aptitude task was administered to establish the participants’ level of musicality and auditory discrimination skills. The results show significant group differences in tone word learning proficiency by the end of training. English musicians outperformed their non-musician counterparts; however, the Thai musicians were not significantly different from the Thai non-musicians. Results from regression analyzes further show that higher musical aptitude scores predicted tone word learning success for the English group but not for the Thai group. These findings suggest that the influence of musical experience in constructing novel lexical representations of tone words differs as a function of linguistic background.
