Phonological Well-Formedness Constraints in Mandarin Phonotactics: Evidence From Lexical Decision

Abstract

This article investigates the role of phonological well-formedness constraints in Mandarin speakers’ phonotactic grammar and how they affect online speech processing. Mandarin non-words can be categorized into systematic gaps and accidental gaps, depending on whether they violate principled phonotactic constraints based on the Obligatory Contour Principle (OCP). Non-word acceptability judgment experiments have shown that systematic gaps received lower wordlikeness ratings than accidental gaps. Using a lexical decision task, this study found that systematic gaps were rejected significantly faster than accidental gaps, even after lexical statistics were taken into account. These findings thus provide converging evidence for the essential status of the OCP-based phonotactic constraints in Mandarin speakers’ phonological knowledge.
