Pronouns in competition: Predicting acquisition delays cross-linguistically

It is well known that English children between the age of 4 and 6 display a so-called Delay of Principle B Effect (DPBE) in that they allow pronouns to refer to a local c-commanding antecedent. Their guessing pattern with pronouns contrasts with their adult-like interpretation of reflexives. The DPBE has been explained as resulting from a lack of pragmatic knowledge or insufficient cognitive resources. However, such extra-grammatical accounts cannot explain why the DPBE only shows up in particular languages and in particular syntactic environments. More-over, such accounts fail to explain why the DPBE only emerges in comprehension and not in production. This paper hypothesizes that the presence or absence of the DPBE can be explained from the properties of the grammar. Fischer’s (2004) op-timality-theoretic analysis of binding, explaining cross-linguistic variation, and Hendriks and Spenader’s (2005/6) optimality-theoretic account of the acquisition of pronouns and reflexives are combined into a single model. This model yields testable predictions with respect to the presence or absence of the DPBE in par-ticular languages, in particular syntactic environments, and in comprehension and/or production
