Toddlerhood is marked by advances in several lexico-semantic skills, including improvements in the size and structure of the lexicon and increased efficiency in lexical processing. This project seeks to delineate how early changes in vocabulary size and vocabulary structure support lexical processing (Experiment 1), and how these three skills…

This two-year longitudinal study examined the role of linguistic interdependence between Spanish and English among a group of first, second, and third generation immigrant Spanish-English bilingual children. Starting from a theoretical perspective on linguistic interdependence that takes into account linguistic constructs and their measurement,…

We investigated the associations between teacher-rated and direct assessments of early elementary students' speech and language skills to explore whether using teachers as primary screeners yielded assessment data that reliably identified young students with language difficulties who many need a more comprehensive evaluation. We assessed first-…

Models of monolingual literacy propose that reading acquisition builds upon children's semantic, phonological, and orthographic knowledge. The relationships between these components vary cross-linguistically, yet it is generally unknown how these differences impact bilingual children's literacy. A comparison between Spanish-English bilingual and…

Most vocabulary growth during the school-age years occurs incidentally. However, little is understood about the influence of language skills on word knowledge growth during reading. Using a pretest-posttest quasi-experimental design, we examined incidental word learning through reading, considering the presence/absence of supportive context and…

This study explored effects of Spanish oral language skills (vocabulary and syntax) on the development of English oral language skills (vocabulary, morphology, semantics, syntax) and reading comprehension among 156 bilingual Latino children in second through fifth grade whose first language was Spanish and whose second language was English. Using…
