Within and Across Language Predictors of Word Learning Processes in Dual Language Learners

Area of Science:

• Psycholinguistics
• Developmental Psychology
• Bilingualism

Background:

• Dual Language Learners (DLLs) are a growing population in early education.
• Understanding their language development is crucial for effective pedagogical approaches.
• Preschool-aged DLLs (3-5 years) present unique challenges and opportunities for language acquisition.

Purpose of the Study:

• To investigate the relationship between vocabulary and grammar comprehension and word learning in preschool DLLs.
• To examine cross-linguistic correlations between Spanish and English language skills.
• To determine if comprehension predicts novel word learning within and across languages, and if dual-language experience moderates these relationships.

Main Methods:

• Hierarchical linear modeling was used to analyze data from 90 preschool-aged Dual Language Learners.
• The study assessed vocabulary and grammar comprehension in both Spanish and English.
• Novel word learning was evaluated, alongside an assessment of dual-language experience.

Main Results:

• Stronger predictive associations were found between comprehension and word learning within each language compared to across languages.
• Cross-linguistic results varied based on the extent of dual-language experience and the specific language domain (vocabulary vs. grammar).
• Knowledge transfer between languages was observed, influenced by structural sensitivity.

Conclusions:

• Dual language exposure may enhance awareness of linguistic parameters, facilitating complex cross-linguistic associations.
• The findings support structural sensitivity theory, suggesting that bilingualism provides a framework for understanding language variations.
• Interventions should consider the interplay between languages and individual differences in dual-language experience.
