Codeswitching is a common feature of bilingual language practices, yet its impact on word learning is poorly understood. Critically, processing costs associated with codeswitching may extend to learning. Moreover, verbs tend to be more difficult to learn than nouns, and the challenges of learning verbs could compound with processing costs…

Research on the effects of bilingualism on third language (L3) development set in bilingual communities is scarce, outdated, and has provided mixed results. This study investigated the effects of exposure and age of onset of acquisition (AOA) of L3-English, as well as first and second language (L1/L2) skills and use, in the development of…

Individuals with lower proficiency in a second language tend to produce more disfluent speech patterns in the second language. Speech disfluencies refer to interruptions in the forward flow of speech and are distinct from the colloquial use of "fluency," to characterize knowledge of a language. Prior research indicates that some speech…

Studies into the role of audiovisual input and captions (i.e., subtitles in the same language as the audio) for L2 learning have shown that such input can positively influence L2 learners' acquisition of lexical items. Few studies have explored the effects of captioning on learners' capacity to segment the speech stream. This study investigates…

A basic question about bilingual development is how the acquisition of one language affects the acquisition of the other. Previous findings are few and mixed. The present study addressed this question with longitudinal data on the dual-language vocabulary growth of 149 US-born children from Spanish-speaking immigrant families, who were followed…

This exploratory, mixed methods study proposes that pedagogical translation be implemented for biliteracy acquisition in mixed heritage language (HL)-second language (L2) secondary Spanish classrooms. It investigates the mediation of pedagogical translation for reading comprehension in two mixed HL-L2 secondary Spanish classrooms at a suburban…

The positive turn in SLA (MacIntyre at al., 2016) has sparked growing interest in the relationship between positive affective variables and language learning outcomes. Foreign language enjoyment has garnered particular attention as a positive emotion supporting language learning behaviors and achievement. However, within psychology and cognition,…

Research has indicated that lexical richness is an important indicator of second language (L2) proficiency. However, most research has examined written, cross-sectional English L2 corpora and does not necessarily indicate how spoken lexical use develops over time or whether observed trends are stable across L2s. This study adds to previous…

Purpose: This 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…

This study investigates the effects of multilingualism and the degree of proficiency in different languages on vocabulary knowledge among Spanish language learners. Participants completed a 160-word meaning recall test designed to measure their knowledge of the 8,000 most frequent Spanish words and a self-assessment questionnaire on their…

This study examines the role of receptive vocabulary knowledge on outcomes of the TOEFL reading comprehension task. Participants included 18 native speakers of Spanish learning English as a foreign language and 17 native speakers of English ranging in age from 19-25 years. Lexical stimuli were presented auditorily and were divided into…

In a replication of Daly and K. Dounavi (2020), the researchers evaluated the effect of foreign tact and bidirectional intraverbal teaching on the emergence of untaught relations. Three university students learned three stimulus sets through three types of teaching: native-foreign intraverbal teaching (vocalizing Spanish words that refer to a…

There are several benefits for Dual Language Learners (DLLs) when their home language is integrated into classroom instruction. For example, instruction in students' home language facilitates the learning of the new language more rapidly and supports bilingualism. One way to enhance young children's language learning is to engage families in home…

Extensive evidence indicates that early vocabulary skills predict later reading development among monolingually developing children. Some evidence suggests that a relationship between vocabulary and later reading also holds across languages among children whose home language differs from the school language. However, these findings have been mixed…

Shifting demographics in K-12 schools have increased Spanish-speaking Multi-Language Learners' (MLLs') enrollment across the United States. While literacy variations between MLLs and proficient English speakers have been studied predominantly with upper elementary students, there remains a need for more exploration among early elementary…
