In American Sign Language (ASL), native signers use eye gaze to mark agreement (Thompson, Emmorey and Kluender, 2006). Such agreement is unique (it is articulated with the eyes) and complex (it occurs with only two out of three verb types, and marks verbal arguments according to a noun phrase accessibility hierarchy). In a language production experiment using head-mounted eye-tracking, we investigated the extent to which eye gaze agreement can be mastered by late second-language (L2) learners. The data showed that proficient late learners (with an average of 18.8 years signing experience) mastered a cross-linguistically prevalent pattern (NP-accessibility) within the eye gaze agreement system but ignored an idiosyncratic feature (marking agreement on only a subset of verbs). Proficient signers produced a grammar for eye gaze agreement that diverged from that of native signers but was nonetheless consistent with language universals. A second experiment examined the eye gaze patterns of novice signers with less than two years of ASL exposure and of English-speaking non-signers. The results provided further evidence that the pattern of acquisition found for proficient L2 learners is directly related to language learning, and does not stem from more general cognitive processes for eye gaze outside the realm of language.

The lack of consistency in how bilingual language dominance is assessed currently impedes cross-experiment comparisons (Grosjean, 1998). We present a paper-and-pencil dominance scale that can be used to quantify the language dominancy of bilingual participants. The scale targets three main criteria important in gauging dominance (Grosjean, 1998; Flege, Mackay & Piske, 2002): percent of language use for both languages, age of acquisition and age of comfort for both languages, and restructuring of language fluency due to changes in linguistic environments. Reaction times from a Spanish/English lexical translation task and filler rates and elongation rates from a Spanish/English sentence translation task support the validity of the scale. The scale can be adapted for nonliterate populations by asking questions verbally and recording responses.

This article challenges a recent proposal for the theoretical interpretation of L1 and L2 interaction that results from the abrupt change of language environment in internationally adopted children. According to this proposal (Pallier, Dehaene, Poline, LeBihan, Argenti, Depoux and Mehler, 2003; Ventureyra, Pallier and Yoo, 2004), such children experience a total loss of their L1, while, as adults, they exhibit a nativelike ultimate attainment of their L2. These authors suggest that what they see as a total loss of L1 allows a resetting of the neural network that normally subserves L1 retention and hence permits a complete acquisition of the L2. Data from two of our own research projects, one on L1 remnants in Korean adoptees in Sweden (see Park, forthcoming), and the other on age of acquisition and ultimate L2 attainment of Swedish (see Abrahamsson and Hyltenstam, in press), which included data from Latin American adoptees in Sweden among other participants, suggest (i) that L1 remnants are indeed maintained, (ii) that L2 attainment is not enhanced by severe L1 attrition, and (iii) that there is an age dimension to both the degree of L1 attrition and the level of L2 ultimate attainment in international adoptees. We therefore contend that a maturational interpretation of language replacement data is preferable.

As Bilingualism: Language and Cognition (BLC) enters its 12th year of publication, we the editors of the journal are pleased to report to the BLC readers that the state of the journal is strong.

Functional magnetic resonance imaging (fMRI) was used to compare brain activation from native Japanese (L1) readers reading hiragana (syllabic) and kanji (logographic) sentences, and English as a second language (L2). Kanji showed more activation than hiragana in right-hemisphere occipito-temporal lobe areas associated with visuospatial processing; hiragana, in turn, showed more activation than kanji in areas of the brain associated with phonological processing. L1 results underscore the difference in visuospatial and phonological processing demands between the systems. Reading in English as compared to either of the Japanese systems showed more activation in inferior frontal gyrus, medial frontal gyrus, and angular gyrus. The additional activation in English in these areas may have been associated with an increased cognitive demand for phonological processing and verbal working memory. More generally, L2 results suggest more effortful reading comprehension processes associated with phonological rehearsal. The study contributes to the understanding of differential brain responses to different writing systems and to reading comprehension in a second language.

Crosslinguistic transfer in bilingual language acquisition has been widely reported in various linguistic domains (e.g., Döpke, 1998; Nicoladis, 1999; Paradis, 2001). In this study we examined structural overlap (Döpke, 2000; Müller and Hulk, 2001) and dominance (Yip and Matthews, 2000) as explanatory factors for crosslinguistic transfer in Persian–English bilingual children's production of novel compound words. Nineteen Persian monolinguals, sixteen Persian–English bilinguals, and seventeen English monolinguals participated in a novel compound production task. Our results showed crosslinguistic influence of Persian on English and of English on Persian. Bilingual children produced more right-headed compounds in Persian, compared with Persian monolinguals, and in their English task, they produced more left-headed compounds than English monolinguals. Furthermore, Persian-dominant bilinguals tended more towards left-headed compounds in Persian than the English-dominant group. These findings point to both structural overlap and language dominance as factors underlying crosslinguistic transfer.

Emotion-memory effects occur when emotion words are more frequently recalled than neutral words. Bilingual speakers report that taboo terms and emotional phrases generate a stronger emotional response when heard or spoken in their first language. This suggests that the basic emotion-memory will be stronger for words presented in a first language. Turkish–English bilinguals performed a deep processing task (emotional-intensity rating) or shallow processing task (counting letter features) and two additional deep processing tasks (translation and word association) on five categories of words (taboo words, reprimands, positive words, negative words, and neutral words), followed by a surprise recall task. Reprimands had the highest recall in English (L2), which may be a novelty effect. If reprimands are set aside, then overall emotion-memory effects were similar in the two languages, with taboo words having the highest recall, followed by positive words. Negative words had no recall advantage over neutral words, an unexpected finding. Results indicate that emotional attributes of words are equally available to boost memory in a first and second language in both shallow and deep processing tasks, athough some task-specific effects did occur.

The present paper summarizes research showing that bilingualism affects linguistic and cognitive performance across the lifespan. The effect on linguistic performance is generally seen as a deficit in which bilingual children control a smaller vocabulary than their monolingual peers and bilingual adults perform more poorly on rapid lexical retrieval tasks. The effect on cognitive performance is to enhance executive functioning and to protect against the decline of executive control in aging. These effects interact to produce a complex pattern regarding the effect of bilingualism on memory performance. Memory tasks based primarily on verbal recall are performed more poorly by bilinguals but memory tasks based primarily on executive control are performed better by bilinguals. Speculations regarding the mechanism responsible for these effects are described.

Previous studies have found that proficiency in a second language affects how the meanings of words are accessed. Support for this hypothesis is based on data from explicit memory tasks with bilingual participants who know two languages that are relatively similar phonologically and orthographically (e.g., Dutch–English, French–English). The present study tested this hypothesis with Chinese–English bilinguals using an implicit memory task – the cross-language repetition priming paradigm. Consistent with the result of Zeelenberg, R. and Pecher, D. (2003), we obtained reliable effects of long-term cross-language repetition priming using a conceptual implicit memory task. Overall, the four experiments support the Revised Hierarchical Model as they demonstrate that low fluency bilinguals can only access the conceptual representation of the second language via the lexical representation of the first language.

We examined how the semantics of causal expressions in Russian and English might differ and how these differences might lead to changes in the way second language learners understand causal expressions in their first language. According to the dynamics model of causation (Wolff, 2007), expressions of causation based on CAUSE verbs (make, force) differ from expressions based on ENABLE verbs (let, help, allow) primarily in terms of the causee's inherent tendency toward an endstate, that is, the causee's physical or intentional inclination for a particular state of affairs. In Russian, the tendency appears to be based on internally derived forces, whereas in English, the tendency may be based on either internally or externally derived forces. In two experiments, English and Russian monolinguals and bilinguals described animations in which the causee's tendency was systematically varied. When the causee's tendency was ambiguous, English and Russian monolinguals’ descriptions differed, suggesting that the causal expressions differ in meaning across languages. Of primary interest, Russian–English and English–Russian bilinguals’ causal descriptions differed from those of monolingual speakers of their first language, and in the direction of the second language, even though they performed the task in the first language. This L2 → L1 transfer is explained in terms of the memory phenomenon of retrieval-induced reconsolidation.

This paper investigates the development of referring expressions in the narratives of children learning English as a second language (L2). Spoken narratives in English were elicited from sixty Chinese-speaking participants at four ages – five, eight, ten, and young adults – using the wordless picture book Frog, where are you? (Mayer, 1969). Narrative analysis focused on the referring expressions that the L2 speakers used to introduce and maintain reference to story characters in the narratives and on the referential appropriateness of those expressions. We then compared the results of this study with other, similar studies on children learning English as a first language (L1) and found both universal and L2-specific patterns in the development of referring expressions in discourse. On the one hand, regardless of whether English is acquired as an L1 or L2, appropriate use of referring expressions in discourse is developed gradually and is influenced by both discourse function (introduction vs. maintenance) and character type (main vs. secondary). On the other hand, L2 children in our study differed from L1 children in previous studies in the development of referential appropriateness in character introduction, the use of pronominals for referent maintenance, and the timeline of the mastery of appropriate forms for referent introductions versus referent maintenance.

This study explores the effects that the age of onset (AO) of second language (L2) acquisition exerts on the attrition of first language (L1) event conceptualization patterns. The subjects studied are L1 Spanish–L2 Swedish bilinguals living in Sweden. The specific research questions addressed in the study concern the role of AO in endpoint encoding and temporal perspectivation in goal-oriented motion events. In view of previous findings on age effects in attrition, it is hypothesized that deviations from Spanish monolingual patterns of conceptualization would be limited basically to subjects whose AO is below 12 years of age. The analyses show that subjects with AO > 12 converge with Spanish monolingual controls on both endpoint encoding and temporal perspectivation strategies, whereas deviations from the controls' performance are found exclusively in subjects with AO < 12. It is suggested, in view of these findings, that subjects with early AO are more dependent on advantageous socio-psychological circumstances such as L1 contact and use in order to fully acquire/maintain Spanish event conceptualization patterns, while L1 maintenance in subjects with late AO is less dependent on these factors. It is concluded that patterns of event conceptualization are affected by age in the same way as formal language skills.

In this paper, I investigate the status of the so-called “weaker” language, French, in French/German bilingual first language acquisition, using data from two children from the DuFDE-corpus (see Schlyter, 1990a), Christophe and François. Schlyter (1993, 1994) proposes that the “weaker” language in the unbalanced children she studied has the status equivalent to that of a second language (L2). I will verify this assumption on the basis of certain grammatical phenomena, such as the use of subject clitics, null subjects and negation, with respect to which L1 and L2 learners show different developmental patterns. The results indicate that the “weaker” language of the children analyzed in this study cannot be interpreted as an L2. Both children behave predominantly like monolingual and balanced bilingual L1 learners in both languages.

Dutch–English participants named words and nonwords with a between-language phonologically inconsistent rime, e.g., GREED and PREED, and control words with a language-typical rime, e.g., GROAN, in a monolingual stimulus list or in a mixed list containing Dutch words. Inconsistent items had longer latencies and more errors than typical items in the mixed lists but not in the pure list. The consistency effect depended on word frequency, but not on language membership, lexicality, or instruction. Instruction did affect the relative speed and number of errors in the two languages. The consistency effect is the consequence of the simultaneous activation of two sublexical codes in the bilinguals' two languages and its size depends on the activation rate of the associated lexical representations (high-frequency words versus low-frequency words and nonwords) and on the decision criteria that monitor the response conflict at the decision level: the timing for responding (time criterion) in each language depends on the composition of the stimulus list and the likelihood of responses in either language.

This study shows further evidence for triggered codeswitching. In natural speech from a Dutch–English bilingual, codeswitches occurred more often directly next to a cognate (or “trigger word”) than elsewhere. This evidence from typologically related, cognate languages extends previous evidence for triggering between typologically unrelated languages. With their large proportion of trigger words, the data provide insight into which words can trigger codeswitches; proper nouns, cognate content words with good and moderate form overlap, and cognate function words all induced codeswitching. Further, this study extends the evidence for triggered codeswitching from speech with relatively little codeswitching to speech with a high codeswitching density. In contrast with earlier work, not only words directly following a trigger word but also words directly preceding one were codeswitched more often than other words, suggesting that the scope of triggered codeswitching depends on the frequency of trigger words and of codeswitches in the speech.

By school age, some bilingual children can score equivalently to monolinguals in receptive vocabulary but still lag in expressive vocabulary. In this study, we test whether bilingual children have greater difficulty with lexical access, as has been reported for adult bilinguals. School-aged French–English bilingual children were given tests of receptive vocabulary and picture naming. The bilingual children's performance was compared to English monolinguals'. We found that bilingual children scored slightly lower on some measures of comprehension and lower on producing the target word. The bilinguals were more likely to correctly identify the target picture even if they had not produced the name. The differences in comprehension but not production could be statistically accounted for by the variation in receptive vocabulary. These results suggest that, school-aged bilinguals can be close to monolinguals in receptive vocabulary but have a harder time accessing the exact word for production. We discuss reasons for this difficulty with lexical access and strategies that children used when they did not produce the target word.

This study investigates ultimate attainment at the syntax–discourse interface in adult second-language (L2) acquisition. In total, 91 L1 (first-language) English, L1 Dutch and L1 Russian advanced-to-near-native speakers of German and 63 native controls are tested on an acceptability judgement task and an on-line self-paced reading task. These centre on discourse-related word order optionality in German. Results indicate that convergence at the syntax–discourse interface is in principle possible in adult L2 acquisition, both in off-line knowledge and on-line processing, even for L1 English speakers, whose L1 does not correspond to L2 German in discourse-to-syntax mappings. At the same time, non-convergence of the L1 Dutch groups and differences in the L2 groups' performance between tasks suggest that asymmetries in L1–L2 discourse configurations and computational difficulties in mapping discourse onto syntax constrain L2 performance.

Turkish as spoken in the Netherlands (NL-Turkish) sounds “different” (unconventional) to Turkish speakers in Turkey (TR-Turkish). We claim that this is due to structural contact-induced change that is, however, located within specific lexically complex units copied from Dutch. This article investigates structural change in NL-Turkish through analyses of spoken corpora collected in the bilingual Turkish community in the Netherlands and in a monolingual community in Turkey. The analyses reveal that at the current stage of contact, NL-Turkish is not copying Dutch syntax as such, but rather translates lexically complex individual units into Turkish. Perceived semantic equivalence between Dutch units and their Turkish equivalents plays a crucial role in this translation process. Counter to expectations, the TR-Turkish data also contained unconventional units, though they differed in type, and were much less frequent than those in NL-Turkish. We conclude that synchronic variation in individual NL-Turkish units can contain the seeds of future syntactic change, which will only be visible after an increase in the type and token frequency of the changing units.

This paper examines article use in the L2-English of adult and child speakers of Russian, an article-less language. In earlier work on articles in adult L2-English, Ionin, Ko and Wexler (2004) proposed that speakers of article-less L1s fluctuate between dividing English articles on the basis of definiteness vs. specificity, as a result of direct access to semantic universals. The present paper examines whether similar fluctuation is present for child L2-English learners. Results of an elicitation study with L1-Russian child and adult learners of English show that both groups of learners exhibit sensitivity to definiteness as well as specificity. At the same time, it is found that the behavior of child L2-learners is more consistent with natural language data than that of adult L2-learners. It is proposed that both children and adults have domain-specific knowledge of semantic universals, but that adults, unlike children, also use explicit strategies. This proposal is considered in light of the literature on explicit vs. implicit knowledge.

The work presented here aims to account for the structure of intrasentential code switching between English and Afrikaans within the framework of feature checking theory, a theory associated with minimalist syntax. Six constructions in which verb position differs between English and Afrikaans were analysed in terms of differences in the strength of particular features associated with functional categories, and the ability of verbs of either language to check these features. Predictions for the well-formedness of code-switched constructions were informed by data elicited from thirty fluently bilingual participants by means of relative judgements of visually-presented code-switched sentences and auditorily-presented code-switched utterances, and a sentence construction task. Findings indicated straightforward support for the predictions for adverb, focalisation, and topicalisation constructions, but less support for embedded that and wh clauses and yes-no questions. Alternative explanations for the latter results are proposed. The work suggests that the same mechanisms and devices proposed to account for monolingual data can also account for code-switching data.
