Anchoring effects in judging grammaticality of sentences

This study was undertaken to examine the anchoring effect in judgments of the grammaticality of sentences. Thirty-three students judged the target sentences involving an intermediate level of judged grammaticality. The first group of 11 subjects judged the sentences paired with the sentences involving high grammaticality (high anchor); the second group of 11 judged them when paired with the sentences involving low grammaticality (low anchor); and the third group of 11 judged them without being given anchor sentences. Analysis shows a clear contrast effect such that the subjects given low-anchor sentences judged the target sentences as more grammatical, while those given high-anchor sentences tended to judge them as less grammatical. Implications of the findings were discussed as they were related to Chomsky's contention about a native speaker's intuition regarding judgments of grammatically.
