Over the past 15 years, a number of acquisition studies have found that young children allowpronouns to take an antecedent within their clause, in violation of Principle B of the bindingtheory. Thus, unlike adults, they allow him to refer to Nathan in thesentence Nathan praised him. Thornton and Wexler present results of a newexperiment testing knowledge of binding within VP ellipsis structures of the form Nathanpraised him, and Albert did too. Whereas adults do not allow the pronouns in each conjunctto have different antecedents, some children do. Based on their findings, Thornton and Wexlerpropose that children's syntactic knowledge is intact (and hence Principle B is beingobserved) but their pragmatic knowledge is incomplete.
