Left-right Periphery Effects: Evidence for Grammars as Parsers It is standardly assumed that mental systems for grammar and processing are separate and thus, the principles of grammar should not reflect the incrementality of either parsing or production, as this is a performance phenomenon. In this talk, we argue to the contrary that the time-linearity of parsing and growth of interpretation are essential to the articulation of the grammar formalism, with intonation providing important clues to the structural analysis to be provided. The particular focus is Korean, which, as a verb-final language provides a particularly strong challenge to sustaining an incremental account of either parsing or production. In this talk, we extend the account of Cann et al in providing a typology across left and right periphery effects to show how constraints such as the Proper Binding Condition and the Right Roof Constraint are satisfied in Korean, while sustaining a fully incremental account of parsing. Essential to this account will be the use of intonation; and we will provide experimental results which demonstrate the role of intonation in supporting incremental structure building both at the left and at the right peripheries.
