Abstract

Functional imaging methods show differences in the pattern of cerebral activation associated with the subject's native language (L1) compared with a second language (L2). In a recent PET investigation on bilingualism we showed that auditory processing of stories in L1 (Italian) engages the temporal lobes and temporoparietal cortex more extensively than L2 (English). However, in that study the Italian subjects learned L2 late and attained a fair, but not an excellent command of this language (low proficiency, late acquisition bilinguals). Thus, ...

Abstract

Two studies are reported in which monolingual and bilingual children (Study 1) and adults (Study 2) completed a memory task involving proactive interference. In both cases, the bilinguals attained lower scores on a vocabulary test than monolinguals but performed the same on the proactive interference task. For the children, bilinguals made fewer intrusions from previous lists even though they recalled the same number of words. For the adults, bilinguals recalled more words than monolinguals when the scores were corrected for differences ...

Abstract

BACKGROUND: Laparoscopic simulator training translates into improved operative performance. Proficiency-based curricula maximize efficiency by tailoring training to meet the needs of each individual; however, because rates of skill acquisition vary widely, such curricula may be difficult to implement. We hypothesized that psychomotor testing would predict baseline performance and training duration in a proficiency-based laparoscopic simulator curriculum. METHODS: Residents (R1, n = 20) were enrolled in an IRB-approved prospective study at the beginning of the academic year. All completed the following: a ...

Abstract

Extensive reading has been drawing increasing attention from L2 educators as a potentially effective form of L2 reading instruction. However, some researchers argue that it is not easy to observe the benefits of extensive reading in the short term. The present study was motivated by the need to elucidate the differential effects of extensive reading on different aspects of foreign/second language ability, some of which may improve more quickly than others. Development of general reading ability and lower-level linguistic ability was ...

Abstract

In the rating scales of major international language tests, as well as in automated evaluation systems (e.g. e-rater), a positive relationship is often claimed between lexical diversity, holistic quality of written or spoken discourses, and language proficiency of candidates. This article reports a posteriori validation study that analysed a sample of the archived data of an international language test to examine empirically to what extent such relationships exist. It is also noted that previous studies on lexical diversity in the field ...

Abstract

Given that summer abroad programs are becoming more and more popular, the aim of the present study is to find out whether foreign language proficiency can be significantly improved during a summer stay of 3–4 weeks. The present study examines learners’ linguistic gains through oral fluency and accuracy measures as well as a listening comprehension task. Learners’ oral fluency is examined in terms of syllables per minute, other language word ratio, filled pauses per minute, silent pauses per minute, articulation rate, ...

Abstract

Learner attributions, perceived causes of success and failure, have received little attention in EFL research. Attributions are categorized as either internal (for example effort) or external (for example luck) and may affect how students learn about and impose order on their world. We investigated the attributions of 505 university students in Hong Kong and the connections between attribution and proficiency, gender, and academic discipline. Student interviews identified 26 common attributions, which were listed in a questionnaire: students were asked to what ...

Abstract

The potential for corpora in language learning has attracted a significant amount of attention in recent years, including in the form of data-driven learning (DDL). Careful not to appear to over-promote the field, enthusiasts have urged caution in its application, in particular with regard to lower-level learners, and have argued that extensive learner-training in corpus techniques is an essential condition for DDL to be successful. Such limits seem eminently reasonable, but there is a notable dearth of empirical studies to support ...

Abstract

A number of theories of second language (L2) acquisition acknowledge a role for explicit L2 knowledge. However, the testing of these theories remains problematic because of the lack of a widely accepted means for measuring L2 explicit knowledge. This article seeks to address this lacuna by examining L2 explicit knowledge from two perspectives. First, it considers explicit knowledge as a construct. How can explicit knowledge be defined? How does it differ from other constructs such as L2 proficiency and language aptitude? ...

Abstract

This study analyses the effects of learning contexts on proficiency development as well as attitudinal and behavioral changes. At a Japanese high school where content-based L2 instruction in global studies is a feature of education, TOEFL scores, international posture, L2 WTC, and frequency of communication in L2 were assessed in the participants’ first year and third year, and compared between (a) study abroad and stay-home groups, and (b) two program options with substantially different class hours and emphasis in education. The ...

Abstract

Event-related brain potentials (ERPs) were used to examine the spatiotemporal cortical activation patterns underlying Chinese and English word generation (forming a new word by adding a stroke or a letter to an old Chinese or English word) for low- and high-proficiency Chinese2013English bilinguals. The results revealed that early visual perceptual processing and word identification were similar between the two languages for the N120 and P220 waveforms. However, a greater negative potential (N2502013350) was associated with Chinese words than with English words ...

Abstract

The Percentage of Proficient Students (PPS) has become a ubiquitous statistic under the No Child Left Behind Act. This focus on proficiency has statistical and substantive costs. The author demonstrates that the PPS metric offers only limited and unrepresentative depictions of large-scale test score trends, gaps, and gap trends. The limitations are unpredictable, dramatic, and difficult to correct in the absence of other data. Interpretation of these depictions generally leads to incorrect or incomplete inferences about distributional change. The author shows ...

Abstract

The network of cortical and subcortical regions that contribute to articulation was examined in bilinguals using functional magnetic resonance imaging. Participants were all fluent in French and English: half were bilingual from birth and half were 'late bilinguals' who had learned French after the age of 12. Overt articulation resulted in the bilateral activation of the motor cortex, basal ganglia and cerebellum, and also the supplementary motor area, independent of the language spoken. Furthermore, the threshold and extent of the network ...

Abstract

The purpose of the present functional magnetic resonance imaging (fMRI) investigation was to examine how language proficiency and orthographic transparency (letter-sound mapping consistency) modulate neural activity during bilingual single word reading. Spanish-English bilingual participants, more fluent in their second language (L2; English) than their native language (L1; Spanish), were asked to read words in the two languages. Behavioral results showed that participants were significantly slower in reading words in their less proficient language (Spanish) than in their more proficient language (English). ...

Abstract

Language selection (or control) refers to the cognitive mechanism that controls which language to use at a given moment and context. It allows bilinguals to selectively communicate in one target language while minimizing the interferences from the nontarget language. Previous studies have suggested the participation in language control of different brain areas. However, the question remains whether the selection of one language among others relies on a language-specific neural module or general executive regions that also allow switching between different competing ...

Abstract

Spanish language tests of 801 Cuban and Mexican immigrants showed no evidence of language loss during 50 years of U.S. residence; a few years after immigration, their English vocabulary approximated that of English monolinguals. The critical-age hypothesis was not supported for the acquisition of English vocabulary when English schooling and language usage were controlled by multiple regression. Most Ss continued to speak about as much Spanish as English; but read, wrote, and heard (on television and radio) far more English than ...

Abstract

Recent research on bilingualism has shown that lexical access in visual word recognition by bilinguals is not selective with respect to language. In the present study, the authors investigated language-independent lexical access in bilinguals reading sentences, which constitutes a strong unilingual linguistic context. In the first experiment, Dutch-English bilinguals performing a 2nd language (L2) lexical decision task were faster to recognize identical and nonidentical cognate words (e.g., banaan-banana) presented in isolation than control words. A second experiment replicated this effect when ...

Abstract

Many studies have reported that word recognition in a second language (L2) is affected by the native language (L1). However, little is known about the role of the specific language combination of the bilinguals. To investigate this issue, the authors administered a word identification task (progressive demasking) on 1,025 monosyllabic English (L2) words to native speakers of French, German, and Dutch. A regression approach was adopted, including a large number of within- and between-language variables as predictors. A substantial overlap of ...

Abstract

Twenty-eight native-English speakers enrolled in beginning and intermediate university Spanish courses participated in a mixed language semantic categorization task in which critical words were presented in English (L1) and Spanish (L2) and repetitions of these words (within- and between-languages) were presented on subsequent trials (i.e., immediate repetition). Event-related potentials were recorded to all items allowing for comparisons of the N400 component to repetitions within- and between-languages as well as to words presented for the first time. Three important findings were observed ...

Abstract

We report three reaction time (RT)/event-related brain potential (ERP) semantic priming lexical decision experiments that explore the following in relation to L1 activation during L2 processing: (1) the role of L2 proficiency, (2) the role of sentence context, and (3) the locus of L1 activations (orthographic vs. semantic). All experiments used German (L1) homonyms translated into English (L2) to form prime-target pairs (pine-jaw for Kiefer) to test whether the L1 caused interference in an all-L2 experiment. Both RTs and ERPs were ...

Abstract

The latency of the brain response to semantic anomalies (N400 effect) has been found to be longer in a bilingual's second language (L2) than in their first language (L1) and/or to that seen in monolinguals. This has been explained in terms of late exposure to L2, although age of exposure and language proficiency are often highly correlated. We thus examined the relative contributions of these factors not only in L2 but also in L1 in a group of Spanish-English bilinguals for ...

Abstract

The aim of the present study was to investigate how multiple languages are represented in the human brain. Event-related brain potentials (ERPs) were recorded from right-handed polyglots and monolinguals during a task involving silent reading. The participants in the experiment were nine Italian monolinguals and nine Italian/Slovenian bilinguals of a Slovenian minority in Trieste; the bilinguals, highly fluent in both languages, had spoken both languages since birth. The stimuli were terminal words that would correctly complete a short, meaningful, previously shown ...

Abstract

Abstract Does the brain of a bilingual process language differently from that of a monolingual? We compared how bilinguals and monolinguals recruit classic language brain areas in response to a language task and ask whether there is a "neural signature" of bilingualism. Highly proficient and early-exposed adult Spanish-English bilinguals and English monolinguals participated. During functional magnetic resonance imaging (fMRI), participants completed a syntactic "sentence judgment task" [Caplan, D., Alpert, N., & Waters, G. Effects of syntactic structure and propositional number on ...

Abstract

Decades of research have shown that, from an early age, proficient bilinguals can speak each of their two languages separately (similar to monolinguals) or rapidly switch between them (dissimilar to monolinguals). Thus we ask, do monolingual and bilingual brains process language similarly or dissimilarly, and is this affected by the language context Using an innovative brain imaging technology, functional Near Infrared Spectroscopy (fNIRS), we investigated how adult bilinguals process semantic information, both in speech and in print, in a monolingual language ...

Abstract

The central issue addressed is whether there are electrophysiological markers for high-language proficiency in adults. Event-related brain potentials (ERPs) were recorded in 19 young adults who demonstrated either "normal" or "high" language proficiency. ERPs were obtained during a sentence-processing task and analyzed for specific response components elicited by different word types. The ERPs in the normal and high-language proficiency groups were similar for early sensory related processing but differed in the later components thought to be more closely related to lexical ...

Abstract

We assessed the effects of age of acquisition and language exposure on the cerebral correlates of lexical retrieval in high-proficient, early-acquisition bilinguals. Functional MRI was used to study Spanish-Catalan bilinguals who acquired either Spanish or Catalan as a first language in the first years of life. Subjects were exposed to the second language at 3 years of age, and have used both languages in daily life since then. Subjects had a comparable level of proficiency in the comprehension of both languages. ...
