What this research studies

This research investigates how Spanish/English bilingual preschoolers perceive and produce speech sounds as they transition from Spanish to English. The study focuses on children who start learning English after being exposed to Spanish, aiming to understand their speech sound abilities in both languages. By tracking the development of these skills over time, the research seeks to identify key factors that influence language learning and literacy. The project involves various tasks to assess speech perception, production, and vocabulary in both languages.

Who could benefit from this research

Good fit: Ideal candidates for this research are low-income preschoolers who are Spanish speakers and are beginning to learn English.

Not a fit: Patients who are not bilingual or who have already achieved proficiency in both languages may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could enhance educational strategies for bilingual children, improving their language development and literacy outcomes.

How similar studies have performed: Previous research has shown success in understanding speech perception in bilingual learners, but this specific focus on sequential bilinguals is relatively novel.
