Explanation:

The behaviorist approach to language development suggests that reinforcement plays a key role in learning words and grammar, while the nativists claim that language is biologically predetermined. The behaviourist approach to language suggests that students could learn a second language by being taught to produce the correct “response” to the appropriate “stimulus” and they also believe that “infants learn oral language from other human role models through a process involving imitation, rewards, and practice. While the nativists claim that the child is born with an already predetermined template for language.
