Co-speech gesture in monolinguals has been linked to several cognitive processes: prompting memory stores, conveying spatial concepts, searching for lexical equivalents, and supporting rhythm and cohesion. The production of co-speech gesture also occurs in spoken language bilinguals. Studies have demonstrated that bilinguals fluent in American…

Bilingual experience has an impact on an individual's linguistic processing and general cognitive abilities. The relation between these linguistic and non-linguistic domains, in turn, is mediated by individual linguistic proficiency and developmental changes that take place across the lifespan. This study evaluated this relationship by assessing…

Three studies compared bilinguals to monolinguals on 15 indicators of executive processing (EP). Most of the indicators compare a neutral or congruent baseline to a condition that should require EP. For each of the measures there was no main effect of group and a highly significant main effect of condition. The critical marker for a bilingual…

The present study explored the relation between language control and nonverbal cognitive control in different bilingual populations. We compared monolinguals, Dutch-French unbalanced bilinguals, balanced bilinguals, and interpreters on the Simon task (Simon & Rudell, 1967) and the Attention Network Test (ANT; Fan, McCandliss, Sommer, Raz,…

We use a time-course analysis to examine the roles of vocabulary size and executive control in bilinguals' verbal fluency performance. Two groups of bilinguals and a group of monolingual adults were tested in English with verbal fluency subtests from the Delis-Kaplan Executive Function System. The two bilingual groups were equivalent in their…

This is a research report on children's use of multiple languages and the school curriculum. The study explored factors that trigger use of, and fluency in, multiple languages; and how fluency in multiple languages relates to thought processes and school performance. Advantages and disadvantages of using only one of the languages spoken were…

The "weaker links" hypothesis proposes that bilinguals are disadvantaged relative to monolinguals on speaking tasks because they divide frequency-of-use between two languages. To test this proposal, we contrasted the effects of increased word use associated with monolingualism, language dominance, and increased age on picture naming times. In two…

Discusses two experiments: the first examining multilinguals ability to maintain native language writing quality and fluency in the presence of unattended irrelevant speech while maintaining a concurrent 6-digit memory load; the second in which bilinguals reduced fluency during writing with a six-digit load only. Results are interpreted in terms…

Bilinguals must have a mechanism for controlling attention to their two language systems in order to achieve fluent performance in each language without intrusions from the other. This paper examines the evidence that the experience of controlling attention to two languages boosts the development of executive control processes in childhood for…

Examined word recognition in early fluent Spanish-English bilinguals using a single word presentation lexical decision task. Reaction times (RT) and event-related brain potentials were measured while subjects made a lexical decision on words and pseudowords in either Spanish or English. Result show associative priming as measured by RTs but both…

A study examined how languages affect memory for narrative. Forty bilingual children aged 8-9 listened to a story in either English or Greek, and then retold it in English or Greek. Unexpectedly, children who heard the story in English and retold it in Greek had significantly better story recall than other groups. Educational implications are…

Examined the view that the variation in bilingual short-term memory capacity is determined by differential rates of subvocal rehearsal between the languages. Auditory memory span and articulation time were measured for three bilingual groups who spoke Finnish at home and Swedish at school, and either Finnish of Swedish in both the home and the…

Examined why adults learning second languages make frequent errors in lexical form. More and less fluent bilinguals in English and Spanish performed a translation recognition task in which they had to decide whether the second of two words was the correct translation of the first. Less fluent participants experienced more interference for…

This collection of papers treats second language users in their own right rather than as failed native speakers, reflecting a new shift within the field of second language acquisition research. The 13 papers are: (1) "Background to the L2 User" (Vivian Cook); (2) "Lexical Representation and Lexical Processing in the L2 User"…

The purpose of this investigation was to design and test an information-eliciting question instrument in order to determine whether the structures in the verbal responses of young Mexican-American, bilingual children entering school would reveal the covert mental operations, concepts and oral language skills elicited. The basic objective was to…
