Anaphoric reference to quantified antecedents: an event-related brain potential study.

Area of Science:

• Cognitive Neuroscience
• Psycholinguistics
• Computational Linguistics

Background:

• Anaphoric reference in quantified sentences is complex.
• Positive and negative quantifiers influence reader focus on different entity sets.
• Understanding complement anaphora is crucial for sentence processing models.

Purpose of the Study:

• To investigate how readers process anaphoric reference to quantified antecedents using event-related potentials (ERPs).
• To examine the neural correlates of processing positive versus negative quantifiers and their subsequent anaphoric references.
• To test theoretical accounts of complement anaphora in sentence comprehension.

Main Methods:

• Recorded electroencephalogram (EEG) while participants read sentences with positive or negative quantifiers.
• Presented anaphoric references to either the reference set or the complement set.
• Analyzed event-related potentials (ERPs), specifically the N400 component.

Main Results:

• The pronoun 'their' elicited a larger N400 following negative quantifiers compared to positive quantifiers.
• A larger N400 was observed on disambiguating words for complement set reference after positive quantifiers.
• Conversely, a larger N400 occurred for reference set reference after negative quantifiers.

Conclusions:

• Findings suggest distinct neural processing for positive and negative quantifiers in anaphora resolution.
• The N400 component reflects the integration difficulty associated with complement anaphora.
• Results provide insights into the cognitive mechanisms underlying sentence comprehension and quantifier processing.
