The processing of non-canonically ordered constituents in long distance dependencies by pre-school children: a real-time investigation.

Four experiments were performed which had the goal of determining how and when young children acquire the ability to understand long distance dependencies. These studies examined the operations underlying the auditory processing of non-canonically ordered constituents in object-relative sentences. Children 4-6 years of age and an adult population participated in the study, which employed a cross modal picture priming methodology to determine when constituents in a non-canonical position are reactivated during ongoing sentence comprehension. The results support the view that even very young children have the same structural processing reflex seen in adults. Namely, children re-activate a non-canonically positioned (fronted) direct object NP immediately at the post-verb gap site during sentence processing.
