Role of expectations in sentence integration
Summary
Causal expectations speed up sentence integration when they are met but slow it down when violated. This suggests expectations are selectively generated and guide comprehension processes.
Area of Science:
- Cognitive Psychology
- Psycholinguistics
- Computational Neuroscience
Background:
- Understanding how people process language and integrate information is crucial.
- Causal expectations play a significant role in predicting upcoming events during discourse comprehension.
Purpose of the Study:
- To investigate the influence of causal expectations on sentence integration.
- To determine how expectation fulfillment or violation affects reading times and judgments.
Main Methods:
- Three experiments were conducted using high-expectation and low-expectation texts.
- Participants read narratives and judged target sentences for relatedness, with reading times recorded.
Main Results:
- Faster unrelated judgments followed high-expectation texts.
- Slower reading times occurred for expectation-violating sentences in high-expectation texts.
- Faster reading and judgments were observed for expectation-fulfilling sentences.
Conclusions:
- Results support a selective generation model of expectations.
- Expectations guide sentence integration, aiding fulfillment and hindering violation.
- No evidence suggests expectations are highly specific predictions.
