Abstract
We present the results of three experiments investigating the interpretation of comparative constructions involving pronominal reference in which binding Principle C is violated. We show that both children and adults retrieve interpretations that are not predicted. On the one hand, children appear to represent elided pronominal material functionally instead of in a strict identity relation with a pronoun on the surface, generating interpretations that are entirely unexpected from the perspective of the adult grammar. On the other, adult participants often appear to ignore Principle C, being influenced by factors such as prosodic focus, the type of comparative, and structural position of the pronoun. We propose that the way in which the sentence processor is deployed in the incremental processing of such comparative constructions gives rise to so-called acceptable ungrammaticality.
