Verified step by step guidance

1. Understand the concept of a 'sensitive period' in language learning, which refers to a specific time frame in an individual's development when they are particularly receptive to acquiring certain skills or knowledge, such as language.
2. Review the Nativist theory of language acquisition, which posits that humans are born with an innate ability to learn language. This theory suggests that there are biological mechanisms that facilitate language learning during certain periods of development.
3. Consider the key proponents of the Nativist theory, such as Noam Chomsky, who introduced the idea of a 'language acquisition device' (LAD) that is activated during these sensitive periods.
4. Contrast the Nativist theory with other theories of language acquisition, such as the Behaviorist theory, which emphasizes learning through reinforcement and imitation, and the Interactionalist theory, which focuses on the role of social interaction in language development.
5. Recognize that the concept of a sensitive period aligns with the Nativist theory, as it supports the idea of an innate biological timetable for language learning, distinguishing it from other theories that do not emphasize innate biological factors.
