  • Chomsky

        • Can follow simple instructions
      • 2-3 years
        • Links words together, for example 'me car'

      • Crucial in order for children to learn language
      • The critical period is identified as being 'infancy and childhood'
      • Chomsky believes that language would not develop with LAD
      • Children who have been exposed to more than one language from birth will be more fluent in both rather than later on in life
      • Children are preprogramed to acquire language and it evolves naturally
    • Chomsky states that children will still make pluralising errors
      • Chomsky believes that his theory can be applies to all languages as they all contain nouns, verbs, constantans, and vowles
    • Criticisms
      • There is a lack of scientific evidence to support his theory
      • He puts emphasis on grammar in sentence development rather than meaning
      • Bruner argues that children require social interaction in order to develop language
        • Bruner has a bigger influence
      • His theory did not take into account
