Toward a cognitive psychology of syntax: Information processing contributions to sentence formulation.

Abstract

it is widely acknowledged that characteristics of the general information processing svstem in which sentence formulation occurs mav provide constraints on syntax in language use. This paper proposes one possibli&urce of such constraints. Evidence is reviewed indicating that the syntax of sentences may .to some degree reflect the transient processing demands of lexical retrieval, suggesting an interaction between syntactic and lexical processing. Specifically, the syntactic structure of utterances appears to be sensitive to the accessibility of lexical information, with phrases containing more accessible information occurring earlier in sentences. The existence of such an interaction argues that the utterance formulation system is not strictly hierarchical, as most current approaches to sentence production imply. A broad framework for models of production is outlined that incorporates these interactions within a limited-capacity processing system. This framework also permits a resolution of contradictions in the literature on pragmatic determinants of constituent order in adult language use.
