Semantic Relations Cause Interference in Spoken Language Comprehension When Using Repeated Definite References, Not...

Area of Science:

• Psycholinguistics
• Cognitive Science
• Computational Linguistics

Background:

• Referential expressions (e.g., pronouns, names) are crucial for discourse coherence.
• The salience of a referent influences the choice between pronouns and full noun phrases.
• Current theories like Discourse Prominence Theory and Informational Load Hypothesis attempt to explain these preferences.

Purpose of the Study:

• To investigate how referent status in discourse affects spoken language comprehension.
• To examine the processing differences between pronouns, repeated definite references, and new references.
• To determine the influence of long-term semantic memory on the processing of different referential expressions.

Main Methods:

• Two visual-world experiments were conducted.
• Participants' eye movements (fixations) were recorded during spoken language comprehension.
• The study analyzed processing times for referents following different types of referential expressions.

Main Results:

• Spoken language comprehension showed delayed fixations to referents after repeated definite references compared to pronouns.
• Repeated references are processed differently than new references.
• Long-term semantic memory representations differentially affect the processing of pronouns and repeated names.

Conclusions:

• Semantic discourse representation plays a significant role in referential processing.
• Pronouns and full repeated references are processed distinctly within semantic memory contexts.
• Current theoretical models of reference processing may require refinement based on these findings.
