Invited Lecture 2 It is standardly assumed that mental systems for grammar and processing are separate with principles of grammar not reflecting the incrementality of processing. I argue however that reflecting time-linearity of growth of interpretation is an essential part of the grammar formalism, with intonation providing important clues to the analysis a parser has to provide. I demonstrate how real-time processing of long-distance dependency in Korean, a typical head-final language, is incremental, speakers using clues from case and prosody. I adopt Dynamic Syntax (DS, Cann et al 2005), which assumes that structure building is incremental, and left-to-right. In DS, long-distance dependency definitionally involves the construction of an early underspecified structural relation and its later update, and case may be constructive, allowing the construction of a local argument-node relation in an emergent sentential structure. Prosody is also an important source of structure building, indicating non-locality. In particular, I focus on the role of Intonational Phrase (IP, See Jun 2000 Korean Intonational Model) in on-line structure building. In this talk, I discuss the results of five psycholinguistic tests and corpus studies (Sejong (2002)). Psycholinguistic experiments include (i) off-line phrasing and completion test; (ii) off-line auditory fragment completion; (iii) off-line prosodic phrasing; (iv) on-line frame-by-frame self-paced reading and (iv) on-line cross-modal self-paced comprehension. The results of psycholinguistic tests and corpus extraction studies confirm incrementality of interpretation given indications provided by intonation, and buttress the strong Grammar-Parser correspondence proposed by Dynamic Syntax.
