Lexical guidance in sentence processing: a note on Adams, Clifton, and Mitchell (1998)

Area of Science:

• Psycholinguistics
• Cognitive Science
• Computational Linguistics

Background:

• A self-paced reading experiment by Mitchell (1987) indicated parsing difficulty when a noun phrase follows an intransitive verb.
• This finding supported a two-stage parsing theory, suggesting initial disregard for verb subcategorization.
• Adams, Clifton, and Mitchell (1998) disputed these findings using eye-tracking, citing methodological issues with the original experiment.

Purpose of the Study:

• To re-evaluate Mitchell's (1987) findings on parsing difficulty.
• To determine if the observed difficulties were an artifact of the experimental methodology.
• To investigate the role of verb subcategorization in sentence processing.

Main Methods:

• An eye-tracking experiment was conducted.
• Participants read sentences with noun phrases immediately following intransitive verbs.
• Experimental materials were similar to Adams et al. (1998) but featured longer noun phrases.

Main Results:

• A pattern of reading difficulty, mirroring Mitchell's (1987) findings, was observed.
• The difficulties were present despite using longer noun phrases and an eye-tracking methodology.
• These results suggest Mitchell's findings were not solely due to the presentation method.

Conclusions:

• The findings support the existence of parsing difficulties as originally reported by Mitchell (1987).
• The results indicate that verb subcategorization information may play a role in sentence parsing.
• The study casts doubt on the sufficiency of constraint-based parsing models to explain these phenomena.
