Poverty of the stimulus

In linguistics, Poverty of the stimulus (POS) arguments are arguments that children are not exposed to rich enough data within their linguistic environments to acquire every feature of their language. Poverty of the stimulus arguments are used as evidence for universal grammar, the notion that at least some aspects of linguistic competence are innate. The term "poverty of the stimulus" was coined by Noam Chomsky in 1980. Their empirical and conceptual basis are a topic of continuing debate in linguistics.
