Language development of preschoolers can be positively stimulated and enhanced by exposure to language of peers. Likewise, interactions of young learners with native-monolingual classmates may contribute to their L2 development. However, research on peer interaction effects in young learners' domains of L2 development is meager. This qualitative…

The role of children's receptive vocabulary knowledge in word and nonword reading (decoding) in an orthographically transparent language is debated. Moreover, we have little understanding of how the role of vocabulary might differ between monolingual children and bilingual children from immigrant families (or language minority bilingual children…

Word knowledge and the speed of word processing in monolingual children and adults are influenced by word properties, such as the age of acquisition (AoA), imageability, and frequency. Understanding how different properties of words contribute to the ease of processing by bilingual children is a critical step for establishing models of childhood…

This dissertation investigated how a bilingual's experiences can affect how their first language pronunciation can differ from monolingual speakers of their two languages. We used a methodology incorporating quantitative phonetic measurements of voice onset time and vowel formants, grammar and vocabulary tests, and qualitative measures of language…

Spanish-English bilingual learners are the fastest growing demographic in U.S. elementary schools. Yet many schools, particularly those in new immigration destination regions, continue to measure bilingual students' vocabulary using monolingual norms. This inequitable practice makes it appear as if bilingual learners have lower language abilities…

The aim of this study was to investigate whether bilingually raised children in the Netherlands, who receive literacy instruction in their second language only, show an advantage on Dutch phoneme-awareness tasks compared with monolingual Dutch-speaking children. Language performance of a group of 47 immigrant first-grade children with various…

The importance of input factors for bilingual children's vocabulary development was investigated. Forty-seven Argentine, 42 South Korean, 51 European American, 29 Latino immigrant, 26 Japanese immigrant, and 35 Korean immigrant mothers completed checklists of their 20-month-old children's productive vocabularies. Bilingual children's vocabulary…

This study focused on the role of bilingual versus monolingual preschool education in the development of lexical knowledge in Russian (L1) and Hebrew (L2) among second-generation Russian-Hebrew speaking immigrants in Israel. The study was designed as a longitudinal and comparative study. The lexical knowledge of children was measured three times…

A substantial amount of literature regarding first language (L1) acquisition has shown that reading for meaning significantly contributes to vocabulary expansion and strongly relates to overall academic success. Research in the English as a Second Language (ESL) context, however, has presented mixed results, in particular for recent immigrant…

Bilinguals sometimes report on difficulties in finding words while speaking in the first language (L1) or the second language (L2), which is frequently attributed to the negative influence of one language onto the other. This paper addresses this issue by investigating the relationship between L1 and L2 vocabulary knowledge of Korean-English…
