The processing of Japanese relative clauses

Abstract

Over the past several years, a considerable amount of research on language comprehension has been carried out under the assumption that comprehension crucially involves language-independent cognitive strategies interacting with grammatical properties specific to a given language. Accordingly, the two factors of grammatical structure and cognitive strategies interact to render certain structures relatively more difficult to process than others. For example, it has been suggested that centre-embedded structures are more difficult to process than right-branching structures because centre-embedding interrupts the main clause and imposes a burden on short term memory, thereby making it relatively more difficult for the hearer to obtain closure on the entire sentence (Kuno 1974). Much attention within the cognitive strategies paradigm has been addressed to the comprehension of English complex sentences, and in particular to those sentences containing relative clauses. Since English permits relative clauses to be attached to NPs playing almost any grammatical role, and since, within a relative clause, the relativized NP can itself play almost any role, sentences containing relative clauses have provided a useful arena for testing various proposed cognitive strategies insofar as they relate to complex structures. In particular, much research has been addressed to SVO sentences in which a relative clause is formed on either the subject or object NP, and in which the relative pronoun is either subject or object.
