Tóm tắt	The acceptability judgment task is the modern, quantified successor to informal grammaticality judgments: instead of a single linguist marking a sentence grammatical or not, many participants rate carefully controlled sentences on a graded scale, and the ratings are analyzed statistically. Built on factorial designs with fillers and counterbalancing, and on response formats from Likert scales to magnitude estimation to forced choice, it turns intuition into replicable, gradient data. The approach anchors the experimental-syntax program associated with Jon Sprouse and colleagues, which tests grammatical hypotheses with the same methodological rigor as psycholinguistic experiments.	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.
