The document discusses several theories of language development in children:
- The learning perspective argues that children learn through imitation, punishment and reinforcement. B.F. Skinner's theory of operant conditioning also suggested children learn language through reinforcement.
- The nativist perspective, associated with Noam Chomsky, argues that humans have an innate language acquisition device that allows them to instinctively learn language without instruction.
- Interactionists, such as Lev Vygotsky, believe that both biological and social factors influence language development. Vygotsky's zone of proximal development describes how children learn through interactions with more knowledgeable others.
- Other theories discussed include Piaget's concepts of assimilation and accommodation, the theory of language codes,
