Context influences how we understand sentences with ambiguous phrases. Our study shows that matching the context to the sentence meaning speeds up reading, demonstrating the power of thematic expectations in language processing.
Area of Science:
- Cognitive Psychology
- Psycholinguistics
- Computational Linguistics
Background:
- Thematic roles are crucial for sentence comprehension.
- Ambiguous phrases pose challenges for readers.
- Discourse representation influences interpretation.
Purpose of the Study:
- To investigate how context affects thematic processing of ambiguous prepositional phrases.
- To examine the role of verb repetition in thematic interpretation.
- To understand how wh-words bias interpretation of subsequent adjuncts.
Main Methods:
- Participants read sentences with locative or temporal prepositional phrases.
- Contextual sentences (locative or temporal) preceded target sentences.
- Verb repetition was manipulated between context and target sentences.
Main Results:
- Context successfully guided thematic expectations.
- Congruent context-target pairs were read faster than incongruent pairs.
- Verb repetition did not affect the thematic congruence effect.
Conclusions:
- Context plays a significant role in resolving thematic ambiguity.
- Thematic expectations, driven by context, impact reading speed.
- Wh-words may establish thematic roles that bias subsequent interpretations.
