Tóm tắt	In the elicited imitation task, participants listen to spoken sentences — typically of increasing length and grammatical complexity — and repeat each one back. The key insight is that when a sentence exceeds short-term verbatim memory, accurate reproduction is impossible by rote echoing; the listener must comprehend the sentence and reconstruct it through their own grammar. Reproduction accuracy therefore indexes implicit linguistic proficiency rather than parroting. Widely used in second-language acquisition as an efficient proficiency measure and in child-language research to gauge developing grammar, it has been validated as a window onto implicit knowledge.	The grammaticality judgment task asks speakers to decide whether a sentence is grammatical — well-formed according to the rules of their language — and treats that decision as evidence about the mental grammar that produces it. Rooted in Noam Chomsky's generative program, where the native speaker's intuition is the primary data of linguistics, the task ranges from a single linguist consulting their own intuitions to large controlled experiments with binary, scaled, or forced-choice responses. It is a workhorse of syntactic theory and of second-language acquisition research, where it probes what learners know about a target language beyond what they can produce.
