Drawing on the framework of Dynamic Systems Theory that affords a holistic approach to understand the language development, the current study conducted a cross-sectional and longitudinal analyses of how 51 Japanese learners of English with various experiential, cognitive and sociopsychological profiles differentially attained two different aspects of L2 pronunciation (comprehensibility, accentedness) in foreign language classroom settings. The participants engaged in four weeks of explicit pronunciation instruction. Their extemporaneous speech was collected via a picture description task at the beginning and end of the project. Subsequently, the pre- and post-test samples were rated for accentedness and comprehensibility, and then linked to a range of individual differences (IDs) factors including aptitude, motivation, anxiety, and English learning experience specific to L2 pronunciation development. At the outset of the project, the cross-sectional results suggested (a) three types of IDs examined in the current thesis were relatively independent from each other, and (b) recent L2 learning outside the classroom and anxiety levels were the strong predictors of both comprehensibility and accentedness, whereas and phonemic coding ability was uniquely linked to accentedness. Concerning the improvement in comprehensibility and accentedness after the intervention, the result of longitudinal study demonstrated the overall effectiveness of pronunciation instruction. However, no IDs showed interaction effect on the effectiveness of pronunciation instruction. Based on the findings, I discuss L2 pronunciation learning as a multifaceted, dynamic and ever-changing system as a result of complex interactions between multiple ID factors and pronunciation dimensions.
