Language dominance predicts cognate effects and metalinguistic awareness in preschool bilinguals

Bilingual Toddlers' Vocabulary Growth Interacts with Existing Knowledge and Cross-Linguistic Similarity

We explored whether bilingual toddlers make use of semantic and phonological overlap between their languages to learn new words. We analysed cross-sectional and longitudinal CDI data on the words understood and produced by 1.0 to 3.0-year-old bilingual toddlers with English and one additional language. Cognates were more likely to be understood and produced compared to non-cognates. Cognate effects were modulated by whether the toddler knew the translation equivalent in the other language, highlighting that young learners are sensitive to the similarities across their languages. Additionally, exploratory analyses suggest that children with smaller vocabularies rely more on translation equivalents to support the acquisition of difficult words. Children with larger vocabulary sizes exhibited no preference for translation equivalents in comprehension, and a preference for new concepts in production. The rapid acceleration of vocabulary growth in the second year of life may explain this developmental change in translation equivalent preference.

Metalinguistic and Reading Skills in a Sample of Colombian Children with Attention Deficit Hyperactivity Disorder

Objective: This study aimed to examine metalinguistic skills and reading processes in children diagnosed with ADHD, compared to a matched control group. Method: An explanatory experimental design was employed, involving a sample of 194 children from Manizales, comprising 97 children diagnosed with ADHD and 97 controls. The study utilized tasks from the Children's Neuropsychological Assessment (CNA) protocol to assess metalinguistic and reading abilities. Results: Children with ADHD exhibited significantly lower performance across all metalinguistic and reading tasks compared to the control group, except for spelling and silent reading comprehension tasks. Conclusions: These findings corroborate previous research conducted in Manizales, underscoring the specific challenges in metalinguistic and reading domains among children with ADHD. Future research should explore the influence of working memory on phonological awareness and its implications for metalinguistic skills and reading development.

Bilingualism and Development of Literacy in Children: A Systematic Review

Background

The importance of biliteracy in bilingual children's development has been widely investigated and discussed for the last several decades, suggesting beneficial effects of writing and reading in two languages for bilingual children as well as for adult second language learners.

Objective

To analyze research on the link between bilingualism and literacy development in two or more languages and the factors that may influence a successful or problematic biliteracy acquisition. RQ (1): What is the relationship between bilingualism and literacy of bilingual children? RQ (2): What strategies are used to develop biliteracy?

Design

The review analyzes 50 studies of literacy development in bilingual children. The selected articles have been separated based on their methodology: 25 articles gave a critical analysis of more than 1,100 studies on the topic, strengthening the theoretical basis of existing research, and 25 other articles were empirical research articles demonstrating practical evidence for the former.

Results

Our analysis revealed that literacy in bilinguals, or biliteracy, can be seen as a necessary condition for fluent development of bilingualism, though it is not a necessary condition (which is explained by the difference between structures of specific languages and writing systems, instruction in literacy, and cognitive baggage invoked by the task used to measure the skill) (Bialystok, 2002). Research suggests that bilingualism impacts children's ultimate acquisition of literacy via the beneficial effects of bilingualism overall: advanced biliteracy boosts the development of phonological and phonemic awareness and metacognitive abilities. Thus, biliteracy can be considered as an advantage in terms of maintaining bilingual acquisition in general and developing writing skills in particular.

Conclusion

There is a lack of studies on the development of writing skills in different educational contexts, across countries and cultures, which must be addressed and complemented by new empirical research. Research will enable policymakers to improve educational programs in accordance with the needs of bilingual children, who are the majority in the current global population.

The Effect of Phonological Overlap on English and Spanish Expressive Vocabulary

PURPOSE

This study examined the effect of phonological overlap on English and Spanish expressive vocabulary accuracy as measured by the bilingual Expressive One-Word Picture Vocabulary Test-Fourth Edition (EOWPVT-IV). We hypothesized that if languages interact during an expressive vocabulary task, then higher phonological overlap will predict higher expressive vocabulary accuracy, especially in the nondominant language.

METHOD

Twenty English-dominant bilingual children (English-Spanish) completed the bilingual EOWPVT-IV. We calculated phonological overlap between 117 English and Spanish words included in the bilingual EOWPVT using the Crosslinguistic Overlap Scale for Phonology.

RESULTS

Generalized logistic mixed-effect models revealed that phonological overlap and word frequency predicted vocabulary accuracy in Spanish, in addition to item difficulty. Age and item difficulty were the only predictors of English accuracy.

CONCLUSIONS

Phonological overlap was a significant predictor of Spanish vocabulary accuracy (the least dominant language of the children in our sample), suggesting a transfer between vocabulary in the dominant language into vocabulary in the least dominant language. Future studies should investigate how languages interact in bilingual children to provide us with information about how to create and administer vocabulary tests that represent vocabulary in each language and use vocabulary teaching strategies that promote dual language development.

How does bilingual experience influence novel word learning? Evidence from comparing L1-L3 and L2-L3 cognate status

Bilingual experience exerts a complex influence on novel word learning, including the direct effects of transferable prior knowledge and learning skill. However, the facilitation and interference mechanism of such influence has largely been tangled by the similarity of the previously learned word knowledge. The present study compared Chinese-English bilinguals' paired-associate learning of nonwords in logographic and alphabetic writing systems. The logographic nonwords resemble the form and meaning of L1 Chinese words in varying degrees, being cognates, false cognates, or non-cognates of Chinese. The alphabetic nonwords resemble the form and meaning of L2 English words, being cognates, false cognates, or non-cognates of English. The learning sequence of logographic and alphabetic words was cross-balanced. The learning results were measured in production and recognition tasks. As for learning the logographic nonwords, both the recognition and production results showed that cognates were learned significantly faster than the non-cognates, and the false cognates were also learned significantly faster than the non-cognates. This suggests stronger facilitation rather than interference from L1 on novel word learning. As for learning the alphabetic nonwords, both the recognition and production results revealed that cognates were learned significantly faster than the non-cognates, but false cognates showed no advantage over the non-cognates. This indicates that interference from L2 is stronger than that from L1. Taken together, the results provide new evidence for the dissociable facilitation and interference effects of bilingual experience. These results carry potential educational implications in that learning novel words depends on substantial bilingual experience.
