A Longitudinal Investigation of the Relations Between Emergent Bilingual Children's Language Experience and Bilingual Language Outcomes.
Article in Journal of speech, language, and hearing research : JSLHR, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study aims to characterize Spanish-English emergent bilingual (EB) children's language experiences and to examine how these experiences contribute to their bilingual development over a 2-year period. All EB children were enrolled in dual language immersion (DLI) programs. This setting provides a unique opportunity to explore how bilingual language experiences shape bilingual language development across time.
methodFifty-seven Spanish-English EB children participated in the study. Bilingual language skills were assessed at two time points: Time 1 (2019) and Time 2 (2021). Participants were in Grade 1 or 3 at Time 1 (
resultsOver time, teacher-reported Spanish experience at school increased and English experience decreased, while child-reported English experience at home remained stable. Except for Spanish vocabulary, significant gains were found for all language measures, indicating continuous development trajectories. Teacher-reported English experience at Time 1 positively predicted English vocabulary gains. Time 2 teacher-reported Spanish experience and child-reported English experience negatively predicted Spanish vocabulary growth, suggesting possible trade-offs.
conclusionsThis study highlights the importance of balanced, high-quality bilingual experience across home and school. DLI programs support growth in multiple language domains, though Spanish expressive vocabulary may need targeted support. Findings have educational and clinical implications for assessment, early intervention, and promoting heritage language use without compromising English-language development.
