Parsers and Grammars: A Tutorial Overview from the Linguistics Building

Area of Science:

• Psycholinguistics
• Computational Linguistics
• Cognitive Neuroscience

Background:

• The relationship between formal grammars and human language processing remains a key area of inquiry.
• Recent advancements in experimental research, particularly electrophysiology, offer new insights into cognitive processes.
• Understanding how parsing systems handle complex structures is crucial for linguistic theory.

Purpose of the Study:

• To re-evaluate the connection between grammars and processing systems.
• To investigate the role of processing strategies and heuristics in language comprehension.
• To explore how grammatical illusions inform our understanding of parser-grammar interactions.

Main Methods:

• Review of experimental research, with a focus on electrophysiological studies from the past 15 years.
• Analysis of how parsing systems manage morphosyntactically complex structures.
• Examination of grammatical illusions and their implications for processing models.

Main Results:

• Parsing systems appear to adhere to grammatical laws rather than solely relying on processing shortcuts.
• Grammatical illusions provide insights into explanatory principles governing parser-grammar relations.
• The duration of illusions is linked to their 'templatability'—how easily they form gestaltic templates.

Conclusions:

• Grammatical illusions are valuable tools for understanding language processing.
• Some perceived illusions may represent grammar functioning in a slowed-down manner.
• The study redefines parser-grammar relations by highlighting the role of templated processing and grammatical adherence.
