Previous studies found that bilingual children and adults with typical language development (TLD) perform better than monolinguals in novel word learning, but show lower scores on lexical retrieval tasks (e.g., naming known words). Children with developmental language disorder (DLD) lack in their abilities in both tasks compared with children with…

In error analyses using sentence repetition data, most authors focus on word types of omissions. The current study considers serial order in omission patterns independent of functional categories. Data was collected from Russian and German sentence repetition tasks performed by 53 five-year-old bilingual children. Number and positions of word…

Research on assessing English as a foreign language (EFL) development has been growing recently. However, empirical evidence from longitudinal analyses based on substantial samples is still needed. In such settings, tests for measuring language development must meet high standards of test quality such as validity, reliability, and objectivity, as…

This study addresses the question of how age of acquisition (AoA) affects grammatical processing, specifically with respect to inflectional morphology, in bilinguals. We examined experimental data of more than 100 participants from the Russian/German community in Berlin, all of whom acquired Russian from birth and German at different ages. Using…

Using data from seven cohorts of language immersion lottery applicants in a large, urban school district, we estimate the causal effects of immersion programs on students' test scores in reading, mathematics, and science and on English learners' (EL) reclassification. We estimate positive intent-to-treat (ITT) effects on reading performance in…

This study examines the development and evaluation of a bilingual Vocabulary Size Test (VST, Nation, 2006). A bilingual (English-Russian) test was developed and administered to 121 intermediate proficiency EFL learners (native speakers of Russian), alongside the original monolingual (English-only) version of the test. A comparison of the bilingual…

The study examined two questions: (1) do the greater phonological awareness skills of bilinguals affect reading performance; (2) to what extent do the orthographic characteristics of a language influence reading performance and how does this interact with the effects of phonological awareness. We estimated phonological metalinguistic abilities and…
