We are interested in...


Second-language learning of speech prosody

It is well established that the first language (L1) is claimed to be responsible for second-language learners’ (in)ability to process sounds in a new language. However, the conditions under which the L1 facilitates or inhibits the learning of new sounds have yet to be understood. Adopting phonetic and psycholinguistic approaches, our research focuses on how lexical tones (Mandarin tones: /pā/ ‘eight’ T1, /pá/ ‘to pull out’ T2, /pǎ/ ‘to hold’ T3, /pà/ ‘father’ T4) and lexical stress (English stress: DEsert vs. deSERT) are processed by adult second-language learners who speak different languages as L1.

Sleep-dependent consolidation of lexical tones

Recent evidence shows that sleep plays a crucial role in transforming newly acquired linguistic knowledge into long-term memory. Given unique characteristics of lexical tones (e.g., high talker-variability of pitch), there is still a vast unexplored area in sleep-mediated memory consolidation of tone learning. By combining behavioral experiments and brain imaging technologies (e.g., EEG), we are dedicated to exploring the relationship between sleep and tone learning, providing memory-based insights for cross-language and cross-age learning of lexical tones.

Aging, cognitive, and language learning

Our research is concerned with the well-being of the aging population. Older adults are facing the challenges of age-related dysfunction in language learning and cognition (e.g., memory and attention). Indeed, recent projects have aimed at investigating older adults’ decline in lexical tone learning and the possible relationship with cognitive ability. We also attempt to find evidence that multilingual language experiences (including learning a new language) can mitigate cognitive decline and promote healthy aging.
