People read more complex sentence structures slower, with processing difficulty emerging early in nested syntax. This finding supports expectation-based theories over retrieval-based ones for syntactic complexity.
Area of Science:
- Psycholinguistics
- Computational Linguistics
- Cognitive Science
Background:
- Syntactic complexity influences language processing.
- Existing theories include retrieval-based and expectation-based accounts.
- Understanding the cognitive mechanisms of syntactic processing is crucial.
Purpose of the Study:
- To investigate the processing of syntactic complexity in Japanese.
- To differentiate between retrieval-based and expectation-based accounts of syntactic complexity.
- To identify the locus of processing slowdown in nested structures.
Main Methods:
- A self-paced reading experiment was conducted in Japanese.
- Participants read sentences with four levels of increasing syntactic nesting.
- Reading times for different sentence structures were recorded and analyzed.
Main Results:
- Reading times increased with greater syntactic nesting.
- The slowdown in processing occurred early within the nested structures.
- No significant slowdown was observed when processing verbs at the end of clauses.
Conclusions:
- The findings do not support retrieval-based integration accounts of syntactic complexity.
- Results align with expectation-based accounts of syntactic complexity.
- Processing difficulty in nested structures is likely driven by predictive mechanisms.
