Children aged 5 and adults interpret ambiguous modal verbs similarly, suggesting adult-like logical form (LF) development in children. Difficulties may stem from non-grammatical factors, not LF acquisition.
Area of Science:
- Linguistics
- Developmental Psychology
- Psycholinguistics
Background:
- Children's acquisition of logical form (LF) operations remains debated.
- Ambiguous modal verbs pose challenges in understanding sentence meaning.
Purpose of the Study:
- To investigate children's interpretation of ambiguous modal verbs.
- To compare children's and adults' understanding of logical form (LF).
Main Methods:
- Truth value judgment task administered to 15 children (4;8-6;2) and 37 adults.
- Analysis of sentence interpretations involving the ambiguous modal verb 'yinggai'.
Main Results:
- Both children and adults predominantly favored the epistemic interpretation of 'yinggai'.
- Children's interpretations were found to be adult-like.
Conclusions:
- Supports the view of adult-like logical form (LF) development by age five.
- Suggests that challenges in interpreting covert movements may be due to extra-grammatical factors.
