My research seeks to understand the neural plasticity of language learning by measuring dynamic neural changes with electrophysiological techniques.

Role for lifelong tuning of linguistic representation: In a series of language training experiments, I studied the experience-dependent malleability of people’s syntactic knowledge. I found that sensitivity to native language statistical information continues across the life span, even after linguistic knowledge has already been acquired and consolidated. Eye-tracking results showed preschoolers and adults were able to reshape their existing syntactic preference about specific verbs (verb bias) by implicitly keeping track of the co-occurrence information about each familiar verb and upcoming syntactic structures in their recent language experience. My work highlighted the role of a flexible learning system in our lifelong experiences of language usage.

Neural plasticity of linguistic statistical learning: How does the human brain adapt to the dynamic change of statistics in the language input? I used Event-related potentials (ERPs) and EEG to explore learning-induced neural plasticity as learners’ continuously accumulate novel linguistic information. In the context of verb bias learning, the ERP results revealed a dynamic shift in the nature of sentence processing as learners’ experience with novel verbs increased. In the context of cross-situational meaning acquisition, EEG characteristics during the visual processing of corresponding scenes separate successful from less successful vocabulary learners.
