“…A potential case in point involves Principle B of the Binding Theory, which governs the distribution of pronouns (Chomsky, 1981). Numerous studies have revealed a discrepancy between child and adult coreference judgements for pronouns: first language (L1) acquirers have considerable difficulty in mastering properties related to Principle B (e.g., Chien and Wexler, 1990;Deutsch et al, 1986;McDaniel et al, 1990). On most 426 SLA and Binding Principle B accounts, this delay does not reflect a competence problem; children's difficulties are attributed to other factors -for example, lack of certain pragmatic principles, processing problems relating to memory capacity, or problems with the tasks employed to test knowledge of Binding Theory (Chien and Wexler, 1990;Grimshaw and Rosen, 1990;Grodzinksy and Reinhart, 1993;Reinhart, 1986).…”
