요약	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.	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.
