Is There a Cognate Effect in Bilingual Children With Developmental Language Disorder?

An Exploration of the Nature of Vocabulary Change Following Language and Literacy Together Intervention

PURPOSE

This exploratory study evaluates how bilingual first graders' vocabulary use in narrative changed after a Spanish-language intervention that focuses on connection between language and literacy.

METHOD

Ten Spanish-English bilingual first graders produced three English and three Spanish narratives based on the Test of Narrative Language protocol pre- and postintervention. All samples were transcribed. Based on comprehensive word inventories, all words produced by the children were identified as being core words; Tiers 1, 2, and 3 words; and/or cognates in both languages. We also coded all utterances for use of internal state terms (ISTs). We evaluated total and unique production of these kinds of words.

RESULTS

Postintervention children increased their total number of cognates and ISTs across languages. They also increased the unique core words, Tier 1 words, and cognates postintervention. They also used more of each of these kinds of words in Spanish-the language of intervention-than in English.

CONCLUSIONS

Children make qualitative changes to their vocabulary postintervention. There is greater change in the use of core words and Tier 1 words in Spanish. These increases in productivity and variability were indicated by the number of unique words added to the children's repertoires in ways that supported narrative production.

A Narrative Approach to Synthesizing Research on Vietnamese Bilingual and Monolingual Children

PURPOSE

This review article offers a narrativized synthesis of my research over the past 15+ years with Vietnamese-speaking children based on data collected from individual bilingual and monolingual children in preschool and elementary schools.

METHOD

I begin with a positionality narrative to describe who I am in relation to the research conducted. I provide an overview of the research program including tool building and how my research with bilinguals in the United States led me to international collaborations in Vietnam.

RESULTS

I present main findings from this body of work in three areas: typical bilingual development, reading performance in Vietnam, and characteristics of developmental language disorder in the Vietnamese language. Implications within each area are discussed in terms of clinical application and future research directions. Practitioners and researchers alike can freely access the Vietnamese assessment tools created and validated to date from our website, https://vietslp.sdsu.edu/.

CONCLUSIONS

This research overview aims to offer clinicians and researchers the sociocultural context for understanding the relevance of this body of research. It also serves as an invitation for new generations of scholars, particularly scholars of color, to see their own unique positionings and perspectives as valuable and necessary for scientific innovation and progress.

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.
