English dominance in vocabulary outcomes among bilingual toddlers in Singapore
- Singapore Communicative Development Inventories (18-24 months old)Bilingual language exposure and academic outcomes
- Parent report questionnaires and examination scores
Seeing is believing? Polysemy of perception verbs for belief
- Online game-like computerised 2AFC task (4-6 years old)Are there patterns in the language input to help learners differentiate factive and non-factive verbs?
- Corpus analysis (child-ambient speech corpora)Are learners differentiate factive and non-factive verbs based on patterns in the language input?
- Human simulation paradigm with nonce word sentences (adults)
PhD thesisHow Bilingual Language Experience Shapes the Infant Lexicon: Implications for Word Learning and Lexical Access
ORA depositSupervisors: Prof Kim Plunkett, Dr Janette Chow (University of Oxford)Babies learn a lot in their early years of life. I study how babies learn their first words. Bilinguals need to learn two times the number of words as monolinguals. Some words sound more like each other than others – does this make these words easier to learn? My work looks at how these words that sound alike (cognates) may change how babies learn words and recognise them.
