Referential context and executive functioning influence children's resolution of syntactic ambiguity

Area of Science:

• Developmental Psychology
• Psycholinguistics
• Cognitive Science

Background:

• Classic studies indicate preschoolers' difficulties with online sentence comprehension compared to adults.
• Five-year-olds often fail to use referential context or recover from parsing errors.
• Emerging research suggests delayed sensitivity and a role for executive function in children's parsing abilities.

Purpose of the Study:

• To investigate if children recruit referential context cues with sufficient processing time.
• To examine the role of executive functioning in children's ability to resolve syntactic ambiguity.

Main Methods:

• Two experiments using temporarily ambiguous instructions (e.g., "Put the frog on the pond into the tent").
• Monitoring children's eye-gaze and actions during comprehension.
• Utilizing slow speech rates and between-subjects manipulation of referential context.
• Assessing executive function through tasks like Simon Says and Flanker.

Main Results:

• Eye-movement and action analyses demonstrated emerging sensitivity to referential context in children.
• Children's error rates and failure to revise interpretations were linked to executive function scores.
• Findings indicate children can utilize referential context under specific conditions.

Conclusions:

• Children, like adults, can employ referential context in syntactic processing.
• Domain-general executive functions play a role in resolving syntactic ambiguity in children.
• Processing time and executive capacity are crucial for children's language comprehension development.
