Purpose In this study, the authors explored the impact of test language and cultural status on vocabulary and working memory performance in multilingual language-minority children. Method Twenty 7-year-old Portuguese-speaking immigrant children living in Luxembourg completed several assessments of first (L1)- and second-language (L2) vocabulary (comprehension and production), executive-loaded working memory (counting recall and backward digit recall), and verbal short-term memory (digit recall and nonword repetition). Cross-linguistic task performance was compared within individuals. The language-minority children were also compared with multilingual language-majority children from Luxembourg and Portuguese-speaking monolinguals from Brazil without an immigrant background matched on age, sex, socioeconomic status, and nonverbal reasoning. Results Results showed that (a) verbal working memory measures involving numerical memoranda were relatively independent of test language and cult...
Working memory in multilingual children: Is there a bilingual effect?
Memory, 2011
This research investigates whether early childhood bilingualism affects working memory performance in 6- to 8-year-olds, followed over a longitudinal period of three years. The study tests the hypothesis that bilinguals might exhibit more efficient working memory abilities than monolinguals, potentially via the opportunity a bilingual environment provides to train cognitive control by combating interference and intrusions from the non-target language. Forty-four bilingual and monolingual children, matched on age, sex, and socioeconomic status, completed assessments of working memory (simple span and complex span tasks), fluid intelligence, and language (vocabulary and syntax). The data showed that the monolinguals performed significantly better on the language measures across the years whereas no language group effect emerged on the working memory and fluid intelligence tasks after verbal abilities were considered. The study suggests that the need to manage several language systems in the bilingual mind affects children’s language skills whilst having little impact on the development of working memory abilities.
Verbal working memory in bilingual children
Journal of speech, language, and hearing research : JSLHR, 2004
The present study compared the performance of 44 Latino children on the Competing Language Processing Task (CLPT; C. Gaulin and T. Campbell, 1994) and the Dual Processing Comprehension Task (DPCT; S. Ellis Weismer, 1996). First, it was of interest to know if there were significant differences between children with and without bilingual proficiency on processing tasks that were assumed to require limited vocabulary knowledge. The second goal of this research was to determine whether there were cross-linguistic differences in verbal working memory by examining performance within bilinguals and between children with limited proficiency in a second language. The performance of the participating children was also examined in the context of research with other English-speaking groups. Finally, given that the CLPT and the DPCT may differ in their processing demands (from a relative focus on storage to one of attention inhibition or resistance to interference), it was important to know the ...
The Performance of Bilingual and Monolingual Children on Working Memory Tasks
Iranian Rehabilitation Journal, 2015
Objectives: The purpose of this research was to explore the possible differences in the working memory of monolingual (Persian) and bilingual (Persian-Baluchi) children. We wanted to examine if there is a statistically significant relationship between working memory and bilingualism. Methods: Four working memory (WM) tests, assessing three WM components, were administered to 140 second grade school students, of whom 70 were monolinguals (35 girls and 35 boys) and 70 were bilinguals (35 girls and 35 boys). The tests used are the following: Forward Digit Span Test, Backward Digit Span Test, Non Word Repetition Test, Maze Memory Test. The results of the two groups were analyzed with multi-group confirmatory factor analysis, aiming to find out any differences in the working memory function of bilingual and monolingual children, and to determine which group has an advantage. Results: The multi-group confirmatory factor analysis was used to measure various WM factors across the two langua...
Predictors of processing-based task performance in bilingual and monolingual children
Journal of Communication Disorders, 2016
In the present study we examined performance of bilingual Spanish-English-speaking and monolingual English-speaking school-age children on a range of processing-based measures within the framework of Baddeley's working memory model. The processing-based measures included measures of short-term memory, measures of working memory, and a novel wordlearning task. Results revealed that monolinguals outperformed bilinguals on the short-term memory tasks but not the working memory and novel word-learning tasks. Further, children's vocabulary skills and socioeconomic status (SES) were more predictive of processing-based task performance in the bilingual group than the monolingual group. Together, these findings indicate that processing-based tasks that engage verbal working memory rather than short-term memory may be better-suited for diagnostic purposes with bilingual children. However, even verbal working memory measures are sensitive to bilingual children's language-specific knowledge and demographic characteristics, and therefore may have limited clinical utility.
The present study aimed at comparing the working memory of Greek monolingual students to bilingual ones from migrant backgrounds who all attend primary school. Secondly, an effort was made to investigate the correlation of the working memory with the academic performance in both groups. Moreover, the correlation of the vocabulary strategies, employed by monolingual and bilingual students in an integrated memory-based text framework (Rachanioti, Griva & Alevriadou, 2017), with their working memory was explored. The sample consisted of 20 monolingual and 20 bilingual students of Albanian origin, who attended the 5th and 6th grade of three primary schools in Eastern Thessaloniki, Greece. The monolingual and bilingual students were matched according to their mark reports on academic performance. The Automated Working Memory Assessment (Alloway, 2007) was used to assess the students’ working memory. The data revealed that monolingual and bilingual students did not differ either in the ve...
A multilingual advantage in the components of working memory
This study compared working memory ability in multilingual young adults and their monolingual peers on four components of working memory (verbal and visuospatial storage, verbal and visuospatial processing). The sample comprised 39 monolingual English speakers, and 39 multilinguals, who spoke an African language as their first and third languages, and English as their second language, all with high levels of proficiency. The multilingual young adults came from lower socioeconomic status (SES) backgrounds and possessed smaller English vocabularies than the monolinguals, features which make this group an under-researched population. Both when SES and verbal ability were and were not statistically controlled, there was evidence of a multilingual advantage in all of the working memory components, which was most pronounced in visuospatial processing. These findings support evidence from bilinguals showing cognitive advantages beyond inhibitory control, and suggest that multilingualism may influence the executive control system generally.

The current study explores the influence of socioeconomic status (SES) and bilingualism on the linguistic skills and verbal short-term memory of preschool children. In previous studies comparing children of low and mid-high SES, the terms "a child with low-SES" and "a child speaking a minority language" are often interchangeable, not enabling differentiated evaluation of these two variables. The present study controls for this confluence by testing children born and residing in the same country and attending the same kindergartens, with all bilingual children speaking the same heritage language (HL-Russian). A total of 120 children (88 bilingual children: 44 with low SES; and 32 monolingual children: 16 with low SES) with typical language development, aged 5; 7-6; 7, were tested in the societal language (SL-Hebrew) on expressive vocabulary and three repetition tasks [forward digit span (FWD), nonword repetition (NWR), and sentence repetition (SRep)], which tap into verbal short-term memory. The results indicated that SES and bilingualism impact different child abilities. Bilingualism is associated with decreased vocabulary size and lower performance on verbal short-term memory tasks with higher linguistic load in the SL-Hebrew. The negative effect of bilingualism on verbal short-term memory disappears once vocabulary is accounted for. SES influences not only linguistic performance, but also verbal short-term memory with lowest linguistic load. The negative effect of SES cannot be solely attributed to lower vocabulary scores, suggesting that an unprivileged background has a negative impact on children's cognitive development beyond a linguistic disadvantage. The results have important clinical implications and call for more research exploring the varied impact of language and life experience on children's linguistic and cognitive skills.
