Beyond linear order: The role of argument structure in speaking

Abstract

The current study examines how speakers plan sentences in which two words that form hierarchical dependency relationships - arguments and verbs - appear far apart in linear distance, to investigate how linear and hierarchical aspects of sentences simultaneously shape sentence planning processes. The results of six extended picture-word interference experiments suggest that speakers retrieve sentence-final verbs before the articulation of their sentence-initial patient or theme arguments, but not agent arguments, and before retrieving sentence-medial nouns inside modifiers. These results suggest that the time-course of sentence planning reflects hierarchically-defined dependency relationships over and above linear structure.
