Bilingual first language acquisition (BFLA) has been considered a possible mechanism of contact-induced change in several recent studies (Siegel, 2008, p. 117; Satterfield, 2005, p. 2075; Thomason, 2001, p. 148; Yip & Matthews, 2007, p.15). There is as yet little consensus on the question, with divergent views regarding both BFLA at the individual level and the implications for language change at the community level.

Do Slovak–German bilinguals apply native Slovak phonological and lexical knowledge when segmenting German speech? When Slovaks listen to their native language, segmentation is impaired when fixed-stress cues are absent (Hanulíková, McQueen & Mitterer, 2010), and, following the Possible-Word Constraint (PWC; Norris, McQueen, Cutler & Butterfield, 1997), lexical candidates are disfavored if segmentation leads to vowelless residues, unless those residues are existing Slovak words. In the present study, fixed-stress cues on German target words were again absent. Nevertheless, in support of the PWC, both German and Slovak listeners recognized German words (e.g., Rose “rose”) faster in syllable contexts (suckrose) than in single-consonant contexts (krose, trose). But only the Slovak listeners recognized, for example, Rose faster in krose than in trose (k is a Slovak word, t is not). It appears that non-native listeners can suppress native stress segmentation procedures, but that they suffer from prevailing interference from native lexical knowledge.

This study investigates how categorial (word class) semantics influences cross-linguistic interactions when reading in L2. Previous homograph studies paid little attention to the possible influence of different word classes in the stimulus material on cross-linguistic activation. The present study examines the word recognition performance of Dutch–English bilinguals who performed a lexical decision task to word targets appearing in a sentence. To determine the influence of word class meaning, the critical words either showed a word class overlap (e.g. the homograph tree [noun], which means “step” in Dutch) or not (e.g. big [adj], which is a noun in Dutch meaning “piglet”). In the condition of word class overlap, a facilitation effect was observed, suggesting that both languages were active. When there was no word class overlap, the facilitation effect disappeared. This result suggests that categorial meaning affects the word recognition process of bilinguals.

Typological differences in expressions of motion are argued to have consequences for event conceptualization. In SLA, studies generally find transfer of L1 expressions and accompanying event construals, suggesting resistance to the restructuring of event conceptualization. The current study tackles such restructuring in SLA within the context of bidirectional cross-linguistic influence, focusing on expressions of Path in English and Japanese. We probe the effects of lexicalization patterns on event construal by focusing on different Path components: Source, Via and Goal. Crucially, we compare the same speakers performing both in the L1 and L2 to ascertain whether the languages influence each other. We argue for the potential for restructuring, even at modest levels of L2 proficiency, by showing that not only do L1 patterns shape construal in the L2, but that L2 patterns may subtly and simultaneously broaden construal in the L1 within an individual learner.

This study investigated the role of verbal working memory on bilingual lexical disambiguation. Spanish–English bilinguals read sentences that ended in either a cognate or noncognate homonym or a control word. Participants decided whether follow-up target words were related in meaning to the sentences. On critical trials, sentences biased the subordinate meaning of a homonym and were followed by targets related to the dominant meaning. Bilinguals with high span were faster at rejecting unrelated targets when the sentences ended in a homonym, whereas bilinguals with low span were slower. Furthermore, error rates for bilinguals with low span showed cognate inhibition, while bilinguals with high span showed no effects of cross-language activation. Results demonstrated that bilinguals with high span benefit from shared lexical codes whether these converge on to a single semantic representation (cognates) or not (homonyms). Conversely, bilinguals with low span showed inhibition from the competing lexical codes, even when they converge onto a single semantic representation.

In this article, we provide a framework of bilingual grammar that offers a theoretical understanding of the socio-cognitive bases of code-switching in terms of five general principles that, individually or through interaction with each other, explain how and why specific instances of code-switching arise. We provide cross-linguistic empirical evidence to claim that these general sociolinguistic principles, stated as socio-cognitive constraints on code-switching, characterize multi-linguistic competence in so far as they are able to show how “local” functions of code-switching arise as specific instantiations of these “global” principles, or (products of) their interactions.

If one asks how many languages there are, one can imagine at least three answers: one, over six billion, or 7,358.

In the present article we provide evidence for the occurrence of transfer of conceptualization patterns in narratives of two German–Turkish bilingual groups. All bilingual participants grew up in Germany, but only one group is still resident in Germany (n = 49). The other, the returnees, moved back to Turkey after having lived in Germany for thirteen years (n = 35). The study is based on the theoretical framework for conceptual transfer outlined in Jarvis and Pavlenko (2008) and on the typology of satellite-framed and verb-framed languages developed by Talmy (1985, 1991, 2000a, b) and Slobin (1987, 1996, 2003, 2004, 2005, 2006). In the present study we provide evidence for the hypothesis that language structure affects the organization of information structure at the level of the Conceptualizer, and show that bilingual speakers’ conceptualization of motion events is influenced by the dominant linguistic environment in both languages (German for the group in Germany and Turkish for the returnees). The returnees follow the Turkish blueprints for the conceptualization of motion, in both Turkish and German event construals, whereas the German-resident bilinguals follow the German blueprints, when speaking German as well as Turkish. We argue that most of the patterns found are the result of transfer of conceptualization patterns from the dominant language of the environment.

The starting hypothesis of the keynote article (KA) is that language acquisition plays an essential role in processes leading to grammatical change. Consequently, a minimal requirement, to be met by explanations of diachronic change is that they rely on mechanisms which are operative in acquisition. The KA is therefore an appeal for interdisciplinary cooperation between historical linguistics and acquisition research.

How bilingual children represent procedural versus narrative text is important for both pedagogical and theoretical reasons. To examine this issue, bilingual children and children learning English as a Second Language (ESL) read Hebrew sentences comprising either a procedural (i.e., “how to”) or a narrative text (i.e., description of “doing”) and reading times were measured. Half the children were primed with the same text, in English, in either the same genre or the opposite genre. Text sentences were then randomly sequenced and sentence sequencing mistakes and correct sentence sequencing times were assessed. Irrespective of genre, primed children read the Hebrew test text more quickly, and they read it as quickly as the English prime text. The priming effect was only evident on the last five sentences of each task. Primed children made fewer sentence sequencing mistakes than unprimed children, except when they were primed and tested with procedural text. With text reading times covaried, time for correct sequencing of the sentences showed only a main effect for genre. These data indicate that procedural genre material is harder to process than narrative genre material for bilingual children but that they are not aware of this greater difficulty. The data have important implications for our understanding of the way bilinguals construct mental models.

It has been claimed that due to their experience in controlling two languages, bilinguals exceed monolinguals in certain executive functions, especially inhibition of task-irrelevant stimuli. Here we investigated the effects of bilingualism on an executive phonological task, namely the forced-attention dichotic listening task with syllabic stimuli. In the standard non-forced (NF) condition, the participants reported all syllables they heard, be it from the right or the left ear. In the forced-right (FR) and forced-left (FL) attention conditions, they had to direct their attention to either the right- or the left-ear stimulus and inhibit information coming to the other ear. We tested Finnish monolinguals and early simultaneous Finnish–Swedish bilinguals from two age groups: (30–50-year-olds and 60–74-year-olds). The results showed that the bilinguals performed better than the monolinguals in the FR and FL conditions. This supports the idea of a bilingual advantage in directing attention and inhibiting task-irrelevant stimuli.

This study examines the effect of proficiency and similarity between the first and the second language on grammatical gender processing in L2. In three experiments, we manipulated gender agreement violations within the determiner phrase (DP), between the determiner and the noun (Experiment 1), the postposed adjective and the noun (Experiment 2) and the preposed adjective and the noun (Experiment 3). We compared the performance of German advanced learners of French to that of French native controls. The results showed a similar P600 effect for native and non-native speakers for agreement violations when agreement rules where similar in L1 and L2 (Experiment 1, depending on proficiency), whereas no effect was found for L2 learners when agreement rules varied across languages. These results suggest that syntactic processing in L2 is affected by the similarity of syntactic rules in L1 and L2.

Previous research has reported that bilingual children sometimes produce mixed noun phrases with ‘correct’ gender agreement – as in der dog (der being a masculine determiner in German and the German word for “dog”, hund, being masculine as well). However, these could obviously be due to chance or to the indiscriminate use of a default determiner. In the current study, we established with high statistical reliability that each of three German–English bilingual children, of 2–4 years of age, produced such mixed NPs with ‘correct’ agreement at significantly greater than chance levels. Also noteworthy was the fact that all three children produced such NPs with German determiners and English nouns much more frequently than the reverse. These findings provide a solid statistical foundation for further studies into the phenomenon of mixed noun phrases with ‘correct’ gender agreement.

Preschoolers tend to rely on what speakers say rather than how they sound when interpreting a speaker's emotion while adults rely instead on tone of voice. However, children who have a greater need to attend to speakers’ communicative requirements, such as bilingual children, may be more adept in using paralinguistic cues (e.g. tone of voice) when interpreting a speaker's affect. We explored whether bilingual children are better able than monolingual children to use paralinguistic cues when interpreting a speaker's emotion. While monolingual and bilingual children were equally capable of identifying emotion using affective information in low-pass filtered speech stimuli (Study 1), bilingual children were better able than monolingual children to use tone of voice when judging emotion in natural speech when content was clear (Study 2).

In this study, we explore native and non-native syntactic processing, paying special attention to the language distance factor. To this end, we compared how native speakers of Basque and highly proficient non-native speakers of Basque who are native speakers of Spanish process certain core aspects of Basque syntax. Our results suggest that differences in native versus non-native language processing strongly correlate with language distance: native/non-native processing differences obtain if a syntactic parameter of the non-native grammar diverges from the native grammar. Otherwise, non-native processing will approximate native processing as levels of proficiency increase. We focus on three syntactic parameters: (i) the head parameter, (ii) argument alignment (ergative/accusative), and (iii) verb agreement. The first two diverge in Basque and Spanish, but the third is the same in both languages. Our results reveal that native and non-native processing differs for the diverging syntactic parameters, but not for the convergent one. These findings indicate that language distance has a significant impact in non-native language processing.

This study compares the development and use of evaluative expressions in the English narratives elicited from 80 Chinese–English bilinguals and 80 American monolingual peers at four ages – five, eight, ten, and young adults – using the wordless picture book Frog, where are you? (Mayer, 1969). Results revealed both similarities and differences between monolingual and bilingual groups. On the one hand, regardless of bilingual status, there is a clear age-related growth in the development and use of evaluative expressions. On the other hand, bilingual children in our study differed from monolingual children in the quantity and quality of evaluative clauses used. The results are discussed with respect to linguistic and cultural differences between English and Chinese.

The present study compares the relative effect of inherent lexical aspect and discursive grounding on the use of L2 Spanish Preterit and Imperfect. The study is based on the analysis of responses to a written 40-item discourse-based forced-choice task among 286 English-speaking learners of Spanish. The analysis of data (repeated measures ANOVA) reveals that as learners gain more experience with the target language, the effect of both lexical aspect and grounding on past tense marking increases. That is, contrary to previous predictions, learners constantly move towards prototypical associations of lexical-narrative factors with morphological markers as knowledge of the second language increases. Second, grounding is the construct that most clearly distinguishes learners from native speakers.

This study investigated whether early especially efficient utilization of executive functioning in young bilinguals would transcend potential cultural benefits. To dissociate potential cultural effects from bilingualism, four-year-old U.S. Korean–English bilingual children were compared to three monolingual groups – English and Korean monolinguals in the U.S.A. and another Korean monolingual group, in Korea. Overall, bilinguals were most accurate and fastest among all groups. The bilingual advantage was stronger than that of culture in the speed of attention processing, inverse processing efficiency independent of possible speed-accuracy trade-offs, and the network of executive control for conflict resolution. A culture advantage favoring Korean monolinguals from Korea was found in accuracy but at the cost of longer response times.
