Linguistic acceptability judgments can stem from grammar rules or processing ease. This study suggests Superiority effects in questions may arise from processing difficulty, not just grammar.
Area of Science:
- Psycholinguistics
- Formal Syntax
- Cognitive Science
Background:
- Linguistic unacceptability judgments may result from grammatical deviance or processing difficulty.
- This ambiguity complicates theories distinguishing formal and functional linguistic constraints.
- The Superiority effect, a dispreference in multiple wh-questions, exemplifies this ambiguity.
Purpose of the Study:
- To investigate the source of ambiguity in acceptability judgments for Superiority effects.
- To differentiate between grammatical deviance and processing difficulty as causes of the Superiority effect.
- To examine the role of D-linking in modulating Superiority effects.
Main Methods:
- Acceptability judgment experiments.
- Self-paced reading experiments.
- Analysis of the interaction between wh-phrase type and processing/judgment outcomes.
Main Results:
- Judgments and processing times for Superiority violations correlated with wh-phrase type.
- Exposure increased acceptability judgments while decreasing processing times.
- Reading times strongly predicted acceptability judgments.
- Wh-phrase complexity influenced both judgments and reading times.
Conclusions:
- D-linking effects appear reducible to general cognitive mechanisms.
- Superiority effects may primarily stem from differential processing difficulty rather than purely grammatical constraints.
- Processing difficulty offers a unified explanation for Superiority and D-linking phenomena.
