Supervisors: Efthymia Kapnoula (BCBL), Arthur Samuel (BCBL)
Summary:
- To examine whether listeners with higher speech perception gradiency (i.e., sensitivity to subphonemic differences) reproduce speech sounds more accurately
- To examine whether listeners with higher speech perception consistency (i.e., stability of speech sound encoding) reproduce speech sounds more consistently
Methods: Visual Analogue Scale (VAS), speech imitation task, various behavioral tasks and questionnaires

Summary:
- To track the development of gradiency (i.e., sensitivity to subphonemic differences) and consistency (i.e., stability of speech sound encoding) in English learners of Spanish over a three-year period
- To investigate the relationships between gradiency, consistency, and cognitive load in the processing of accented speech
Methods: Visual Analogue Scale (VAS), pupillometry experiment, behavioral tasks, and linguistic diversity questionnaire

Supervisor: Urs Maurer (Chinese University of Hong Kong)
Collaborator: Shuting Huo (Chinese University of Hong Kong)
Summary:
- Distinct adaptation patterns were found for multiple repetitions in different components
- The mismatch negativity (MMN) combines two processes: an initial adaptation in the N1 and a continuous memory trace effect in the P2
Method: EEG with a pure tone roving paradigm

Supervisor: Tomohiro Inoue (Chinese University of Hong Kong)
Collaborator: Shawn Hemelstrand (Chinese University of Hong Kong)
Summary:
- Phonological similarity, no matter measured objectively (OPS) or subjectively (SPS), appears to have minimal impact on Japanese cognate lexical decision among Cantonese-Japanese bilinguals
- This finding diverges from previous studies conducted on alphabetic languages, which showed a positive relationship between phonological similarity and cognitive processing
Method: Japanese (L2) lexical decision task
