Current Projects
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)
Past Projects
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.

Are bilingual children better at learning more similar languages?
- Online parent-report infant vocabulary questionnaire (12-36 months old)Are bilingual children better at recognising more similar words?
- Online toddler touchscreen vocabulary task (20-24 months old)Do bilingual children retrieve words from both languages at once?
- Lab-based experiment - priming paradigm (20, 25, 30 months old)How does a child's learning environment influence their vocabulary?
- Semantic network analysis of child-directed speech corpora + vocabulary questionnaireHow do we define similarity between words in different languages?
- Online adult behavioural experiment; computational modelling
