Human language learning differs significantly across individuals in the process and ultimate attainment. Although decades of research exploring the neural substrates of language learning have identified distinct and overlapping brain networks subserving learning of different components, the neural mechanisms that drive the large interindividual differences in learning success are still far from being understood. In this talk, I will introduce recent works from my group on neural mechanisms of language learning across multiple components (e.g., auditory and speech category learning, word and grammar learning). With machine learning and predictive modeling techniques, we have identified potential neuromarkers that showed robust predictive powers [...]
This talk presents articulatory and acoustic data in order to investigate the non-coalescence of /h/ in South Jeolla. Seoul Korean speakers produce /pap/ ‘rice’ followed by /hana/ ‘one’ as [pa.pha.na] with the coalescence of /p/ and /h/; this is called an aspiration merger. In South Jeolla Korean, this merger may be blocked, as in cases where speakers produce /pap + hana/ as [pa.ba.na]. Electroglottographic (EGG) data indicates the existence of two groups of South Jeolla speakers: one that merges the plosive and /h/ (the merger group), and the other with the canonical South Jeolla Korean pronunciation that does not merge the [...]
