Michael Tomasello
Poverty of stimulus
child’s knowledge of language can NOT be learnt from caregivers or experience in immediate environment alone
Key points of Universal Grammar
- language is innate
- Language Acquisition Device = brain is hardwired to acquire language with exposure
- poverty of stimulus
Problems with Universal Grammar
- did not focus on how language was developed
- did not focus on features of interaction
- did not complete practical experiments
Key points of Usage-based Theory
- language develops alongside cognitive development
- adult interaction with care-givers assists in language development (e.g. corrective feedback)
- evidence includes imitation, repetition, corrective feedback, recognising grammatical patterns
