The Wug Test was the first experimental proof that young children have extracted generalizable rules from the language around them, rather than simply memorizing words that they have heard, and it was almost immediately adapted for children speaking languages other than English, to bilingual children, and to children (and adults) with various impairments or from a variety of cultural backgrounds. Its conclusions are viewed as essential to the understanding of when and how children reach major language milestones, and its variations and progeny remain in use worldwide for studies on language acquisition. It is "almost universal" for textbooks in psycholinguistics and language acquisition to include assignments calling for the student to carry out a practical variation of the Wug Test paradigm. The ubiquity of discussion of the wug test has led to the wug being used as a mascot of sorts for linguists and linguistics students.
