Phonological vs. natural gender cues in the acquisition of German by simultaneous and sequential bilinguals (German-Russian).

We investigate German-Russian bilingual children's sensitivity to formal and semantic cues when assigning gender to nouns in German. Across languages, young children have been shown to primarily rely on phonological cues, whereas sensitivity to semantic and syntactic cues increases with age. With its semi-transparent gender assignment system, where both formal and semantic cues are psycho linguistically relevant, German has weak phonological cues compared to other languages, and children have been argued to acquire semantic and phonological rules in tandem. German-Russian bilingual children face the challenge of acquiring two different gender assignment systems simultaneously. We tested 45 bilingual children (ages 4-10 years) and monolingual controls. Results show that the children are clearly sensitive to phonological cues, while semantic cues play a minor role. However, monolingual and bilingual children have different defaulting strategies, with monolinguals defaulting to neuter and bilinguals to feminine gender.

Diversity and divergence in bilingual acquisition

AbstractBilingual settings are perceived as exemplary cases of linguistic diversity, and they are assumed to trigger cross-linguistic interaction. The rationale underlying this assumption is the belief that when more than one language is processed in a brain, this will inevitably affect the way in which linguistic knowledge is acquired, stored and used. However, this idea stands in conflict with results obtained by research on children acquiring two (or more) languages simultaneously. They have been demonstrated to be able to differentiate languages from early on and to develop competences qualitatively identical to those of monolinguals. These studies thus provide little evidence supporting the idea that bilingualism must lead to divergent grammatical development.The question then is what triggers alterations of bilinguals’ grammars, especially of the syntactic core, possibly resulting in non-native competences. This has been claimed to occur in the acquisition of second languages, weaker languages of simultaneous bilinguals, or heritage languages. These acquisition types differ from first language development in that onset of acquisition of one language is delayed or that the amount of exposure to one language is reduced. I will argue that age at onset and severely reduced amount of exposure are potential causal factors triggering divergent developments, whereas bilingualism on its own is not a sufficient cause of divergence.

Word Order in Complex Verb Phrases in Heritage Polish Spoken in Germany

This paper deals with word order in complex verb phrases consisting of auxiliaries and infinitive complements in heritage Polish. In Polish, infinitive complements normally follow auxiliaries, but discontinuous structures occur if required by the information structure. We investigate the occurrence and evaluation of adjacent and discontinuous word order patterns in relation to (a) the chronological age at testing and (b) the age of onset of the acquisition of the majority language, German. Therefore, we distinguish between simultaneous bilinguals (2L1, n = 61), early sequential bilinguals (cL2, n = 41) and an age-matched monolingual control group (ML, n = 50). The data consist of elicited oral narratives as well as acceptability judgments. We found that both 2L1 and cL2 bilinguals differ from the ML, but the difference depends on the age at testing and the type of data (oral production or evaluation). While 2L1 bilinguals show a u-curve development, which is shaped by the interplay of delayed acquisition in childhood and attrition in early adulthood, cL2 bilinguals started to prefer discontinuous structures rather early. Only in adulthood do both groups converge and exhibit an overuse and over-acceptance of discontinuous structures compared to the ML, which is due to cross-linguistic influence from German. However, language-internal factors (such as clause structure) also turned out to impact the distribution of adjacent and discontinuous structures in heritage (and monolingual) Polish.

Age of onset, language dominance and dialectal variation: Catalan copula selection in locative contexts with (non-)eventive subjects

ABSTRACT Literature on early language acquisition has observed that age of onset of acquisition (AoA) is relevant for certain grammatical phenomena. Simultaneous bilinguals receive regular and extensive exposure to two languages from birth (Müller, 2009), whereas sequential child learners get in extensive contact to LB once the LA has developed to a certain degree (Meisel, J. M. [2013]. Sensitive phases in successive language acquisition: The Critical Period Hypothesis revisited. In C. Boeckx & K. Grohmann (Eds.), Handbook of biolinguistics (pp. 69–85). Cambridge University Press). Exposure to LB can take place early in childhood (eL2 learners, age 3;0) or starting with elementary school (cL2 learners, age 6;0). In this study, 34 participants were recruited from different Catalan-speaking regions and displayed different AoA-profiles (12 simultaneous, 13 eL2 and 9 cL2 learners) and different degrees of language dominance (17 balanced, 10 Spanish and 7 Catalan dominant). We conducted a Preference Task to examine Catalan copula selection in locative contexts with (non-)eventive subjects, since it may pattern differently in Catalan/Spanish: Both languages select ésser/ser for eventive subjects, non-eventive subjects take estar in Spanish but show variation in Catalan. Our study examines whether the factors AoA, language dominance or the speaker’s linguistic variety determine copula selection. In a nutshell, all speakers preferred ésser with eventive subjects. For non-eventive subjects, the results show that language dominance and speaker’s linguistic variety predict copula preference.

Do Bilinguals Acquire Similar Words to Monolinguals? An Examination of Word Acquisition and the Similarity Effect in Japanese-English Bilinguals' Vocabularies.

Previous research has paid much attention to the overall acquisition of vocabularies among bilingual children in comparison to their monolingual counterparts. Much less attention has been paid to the type of words acquired and the possible transfer or cross-linguistic effects of the other language on vocabulary development. Thus, this study aims to explore similarities and dissimilarities in the vocabularies of simultaneous bilinguals and Japanese monolinguals and considers the possible cross-linguistic similarity effect on word acquisition. Six simultaneous Japanese–English bilingual children (mean age = 34.75 months (2.56)) were language–age-matched with six Japanese monolinguals; their productive vocabularies were compared regarding size and categories. Additionally, characteristic acquired words were compared using correspondence analyses. Results showed that, although delayed due to the reduced inputs, young bilinguals have a similar set of vocabularies in terms of word category as monolinguals. However, bilingual children’s vocabularies reflect their unevenly distributed experience with the language. Fewer interactive experiences with language speakers may result in a lower acquisition of interactive words. Furthermore, there is a cross-linguistic effect on acquisition, likely caused by form similarity between Japanese katakana words and English words. Even between languages with great dissimilarities, resources and cues are sought and used to facilitate bilingual vocabulary acquisition.

Influence of Sequential and Simultaneous Bilingualism on Second Grade Dual Language Students’ Use of Syntax in Reading

This study integrated reading and bilingual theories to examine the reading behaviors of second grade Latinx students in a Dual Language program. It explored how the students’ differing language backgrounds (simultaneous bilinguals and sequential bilinguals who had developed Spanish as a home language) might influence their early reading behaviors. Data sources include Spanish and English informal reading inventories and student interviews. While all students struggled with the syntax of grade-level text in Spanish and English, simultaneous bilinguals’ superior ability to use syntax to self-correct in both languages evidenced a stronger syntactical base. The findings have significant implications for equity of instruction and assessment, including: the need to find new ways to analyze bilingual students’ informal reading inventories from an assets-oriented lens, prudence regarding how informal reading inventory results are used, the need for intensive language development in schools, and the use of caution when applying translanguaging theory to emergent bilingual readers.

Use of Functional Near Infrared Spectroscopy to Assess Syntactic Processing by Monolingual and Bilingual Adults and Children.

This exploratory study assessed the use of functional Near Infrared Spectroscopy (fNIRS) to examine hemodynamic response patterns during sentence processing. Four groups of participants: monolingual English children, bilingual Chinese-English children, bilingual Chinese-English adults and monolingual English adults were given an agent selection syntactic processing task. Bilingual child participants were classified as simultaneous or sequential bilinguals to examine the impact of first language, age of second-language acquisition (AoL2A), and the length of second language experience on behavioral performance and cortical activation. Participants were asked to select the agent of four types of sentences: subject-verb-object (SVO), passive (PAS), subject-extracted relative clause (SR), and object-extracted relative clause (OR) adopted from the “Whatdunit” task by Montgomery et al. (2016). Semantic cues were removed by using inanimate nouns for agents and patients, which constrained participants to make decisions based on syntactic knowledge. Behavioral results showed greater accuracy for canonical SVO and SR sentence types than for noncanonical OR and PAS sentence types, which aligns with prior studies. Neuroimaging results revealed greater hemodynamic responses to relative clauses (i.e., SR and OR sentences) than to simple sentences (SVO and PAS), especially for Chinese-English bilinguals suggesting first-language transfer influencing sentence processing in English. The effects AoL2A and the length of second language experience showed no significant differences between simultaneous and sequential bilinguals or between bilingual adults and children for identifying the correct agent in each sentence. However, neuroimaging results demonstrated greater hemodynamic responses in right dorsolateral prefrontal cortex (DLPFC) and left inferior parietal lobule (IPL) in simultaneous bilinguals compared to sequential bilinguals and greater hemodynamic responses in left and right DLPFC and left IPL among bilingual adults. Different behavioral and neural hemodynamic response patterns afford new insights into the effects of syntactic knowledge on sentence processing.

Simultaneous bilinguals who do not speak a tone language show enhancement in pitch sensitivity but not in executive function

Abstract Previous studies have reported perceptual advantages, such as when discriminating non-native linguistic or musical pitch differences, among first-year infants growing up in bilingual over monolingual environments. It is unclear whether such effects should be attributed to bilinguals’ enhanced perceptual sensitivity and/or cognitive abilities, and whether such effects would extend to adulthood. Twenty-four Dutch, 24 Dutch simultaneous bilingual (DSB), and 24 Chinese Mandarin speakers were examined by three sets of tasks assessing their linguistic pitch and music perception, executive function, as well as interactions across these modalities. Results showed degrees of advantages for DSB and Chinese participants’ over their Dutch peers in lexical tone discrimination and pitch-related music tasks. In tasks related to executive function, no difference was observed between DSB and Dutch participants, while Chinese participants’ performances were modulated by cognitive interference of language processing. Findings suggest that listeners’ enhanced sensitivity to linguistic and musical pitch may stem from acoustic (DSB) and experience (Chinese) rather than cognitive factors. Moreover, Dutch participants showed robust correlations between their linguistic and musical pitch perception, followed by limited correlations in DSB, and virtually no correlation among Chinese participants, illustrating how distinct language experiences can lead to specific pitch perception patterns between language and music.

Early childhood bilingualism: effects on brain structure and function.

Growing up in a bilingual environment is becoming increasingly common. Yet, we know little about how this enriched language environment influences the connectivity of children's brains. Behavioural research in children and adults has shown that bilingualism experience may boost executive control (EC) skills, such as inhibitory control and attention. Moreover, increased structural and functional (resting-state) connectivity in language-related and EC-related brain networks is associated with increased executive control in bilingual adults. However, how bilingualism factors alter brain connectivity early in brain development remains poorly understood. We will combine standardised tests of attention with structural and resting-state functional magnetic resonance imaging (MRI) in bilingual children. This study will allow us to address an important field of inquiry within linguistics and developmental cognitive neuroscience by examining the following questions: Does bilingual experience modulate connectivity in language-related and EC-related networks in children? Do differences in resting-state brain connectivity correlate with differences in EC skills (specifically attention skills)? How do bilingualism-related factors, such as age of exposure to two languages, language usage and proficiency, modulate brain connectivity? We will collect structural and functional MRI, and quantitative measures of EC and language skills from two groups of English-Greek bilingual children - 20 simultaneous bilinguals (exposure to both languages from birth) and 20 successive bilinguals (exposure to English between the ages of 3 and 5 years) - and 20 English monolingual children, 8-10 years old. We will compare connectivity measures and attention skills between monolinguals and bilinguals to examine the effects of bilingual exposure. We will also examine to what extent bilingualism factors predict brain connectivity in EC and language networks. Overall, we hypothesize that connectivity and EC will be enhanced in bilingual children compared to monolingual children, and each outcome will be modulated by age of exposure to two languages and by bilingual language usage.

Assessing Rhotic Production by Bilingual Spanish Speakers

Due to its articulatory precision, the Spanish rhotic system is generally acquired in late childhood by monolingually-raised (L1) Spanish speakers. Heritage speakers and second language (L2) learners, unlike L1 speakers, risk an incomplete acquisition of the rhotic system due to limited Spanish input and possible phonological interference from English. In order to examine the effects of age of onset of bilingualism and cross-linguistic influence on bilinguals’ rhotic productions, twenty-four adult participants (six sequential bilingual heritage speakers, six simultaneous bilingual heritage speakers, six L1 Spanish speakers, six L2 Spanish learners) were audio recorded in a storytelling task and a picture naming task. The alveolar taps [ɾ] and alveolar trills [r] produced in these tasks were examined according to duration of the rhotic sound and number of apical occlusions. Results showed that the sequential bilinguals, but not the simultaneous bilinguals or the L2 learners, patterned similarly to the L1 Spanish speakers in their production of taps and trills. Neither heritage group produced the English alveolar approximant [ɹ]; the L2 learners, on the other hand, did produce [ɹ] when speaking Spanish. The results of this study suggest that early language input can affect the production of sounds that are acquired in late childhood.

Vocabulary Learning Strategies of Italian-Turkish Bilingual Students: Impact of Simultaneous and Sequential Acquisition

Summary Vocabulary learning strategy domain has been one of the areas of research in the language learning strategy field. Bilinguals use different language and vocabulary learning strategies than monolinguals (Hong-Nam & Leavell, 2007; Jessner, 1999). Even though there are numerous studies that investigate and compare monolingual, bilingual, and multilingual language learning strategy use, no studies have been conducted to compare the vocabulary learning strategy use in simultaneous and sequential bilinguals. This paper addresses this gap by investigating and comparing those strategies reported by Italian-Turkish simultaneous and sequential bilingual high school students with a total number of 103 participants, 34 of which are simultaneous bilinguals and the remaining 69 sequential bilinguals. The Vocabulary Learning Strategies Questionnaire (VLSQ) developed by Schmitt (1997) was utilized as the instrument of data collection. We found that simultaneous and sequential bilinguals (a) are medium to high level vocabulary strategy users, (b) report using social strategies the most, (c) do not differ considerably in their choice of vocabulary learning strategy type, but (d) differ substantially in their choices of metacognitive strategy use. The results offer implications for teachers and teacher educators particularly as to how they teach and support bilingual students’ vocabulary learning process in monolingual contexts.

A bilingual advantage in memory capacity: Assessing the roles of proficiency, number of languages acquired and age of acquisition

Aims and objectives: This study examines whether different types of bilingualism modulate memory capacity differently. More specifically, the study assesses the effects of age of acquisition, number of languages acquired and proficiency in the second language (L2) on phonological short-term memory, visuospatial memory and semantic memory. Design: Memory capacity was measured by means of three tasks: the digit span task (phonological short-term memory); the Corsi block task (visuospatial memory); and the word span task (semantic memory). Participants were divided into five groups based on the number of languages acquired, age of acquisition and proficiency: monolinguals, intermediate L2 learners, advanced L2 learners, simultaneous bilinguals and multilinguals. Data and analysis: Analyses of variance were used to analyze participants’ scores for each of the memory tasks. Findings and conclusions: For the word span task, no significant differences were found among the groups, which supports the notion that semantic memory is language independent. Furthermore, intermediate and advanced L2 learners and multilinguals presented significantly higher phonological short-term memory spans compared to simultaneous bilinguals. Finally, intermediate L2 learners and multilinguals significantly outperformed monolinguals on visuospatial memory spans. Results suggest that L2 acquisition might strengthen both visuospatial and phonological short-term memory, which in turn tend to improve as L2 proficiency increases. Originality: While previous studies have provided evidence of a bilingual advantage in memory capacity, these studies have generally grouped different types of bilinguals together (e.g., L2 leaners and heritage speakers). This study takes a step forward by examining differences in memory capacity across different types of bilinguals and in comparison to their monolingual peers in order to better understand the cognitive effects of bilingualism. Significance and implications: When considering age of acquisition, number of languages acquired and proficiency as grouping factors, different effects of bilingualism on memory capacity can be observed. Future studies on this matter should include bilingual participants that are comparable with regard to the aforementioned variables.

Bilinguals benefit from semantic context while perceiving speech in noise in both of their languages: Electrophysiological evidence from the N400 ERP

AbstractAlthough bilinguals benefit from semantic context while perceiving speech-in-noise in their native language (L1), the extent to which bilinguals benefit from semantic context in their second language (L2) is unclear. Here, 57 highly proficient English–French/French–English bilinguals, who varied in L2 age of acquisition, performed a speech-perception-in-noise task in both languages while event-related brain potentials were recorded. Participants listened to and repeated the final word of sentences high or low in semantic constraint, in quiet and with a multi-talker babble mask. Overall, our findings indicate that bilinguals do benefit from semantic context while perceiving speech-in-noise in both their languages. Simultaneous bilinguals showed evidence of processing semantic context similarly to monolinguals. Early sequential bilinguals recruited additional neural resources, suggesting more effective use of semantic context in L2, compared to late bilinguals. Semantic context use was not associated with bilingual language experience or working memory.

Phonetic drift reveals interconnected phonological representations in simultaneous bilinguals: A case study of English and Czech stop consonants

Purpose: The interconnectedness of phonological categories between the two languages of early bilinguals has previously been explored using single-probe speech production and perception data. Our goal was to tap into bilingual phonological representations in another way, namely via monitoring instances of phonetic drift due to changes in language exposure. Design: We report a case study of two teenage English–Czech simultaneous bilinguals who live in Canada and spend summers in Czechia (Czech Republic). Voice onset time (VOT) of word-initial voiced and voiceless stops was measured upon the bilinguals’ arrival to and before their departure from a two-month stay in Czechia. Data and Analysis: Each bilingual read the same set of 71 Czech and 58 English stop-initial target words (and additional fillers) at each time of measurement. The measured VOT values were submitted to linear mixed effects models, assessing the effects of target language, measurement time, and underlying voicing. Findings/Conclusions: After the immersion in a Czech-speaking environment, for both speakers the count of voiced stops realized as prevoiced (i.e., having negative VOT) increased and the measured VOT of voiced stops (appearing different for English and Czech initially) drifted towards more negative (more Czech-like) values in both languages, while no change was detected for the voiceless stops of either English (aspirated) or Czech (unaspirated). The results suggest that the bilinguals maintain three-way VOT distinctions, differentiating voiceless aspirated (English), voiceless unaspirated (Czech), and voiced (English–Czech) stops, with connected bilingual representations of the voiced categories. Originality: Data on phonetic drift in simultaneous bilinguals proficient in their two languages have not previously been published. Significance/Implications: We show that observing phonetic shifts due to changes in the ambient linguistic environment can be revealing about the organization of phonological space in simultaneous bilinguals.

Earlier age of second language learning induces more robust speech encoding in the auditory brainstem in adults, independent of amount of language exposure during early childhood

Learning a second language (L2) at a young age is a driving factor of functional neuroplasticity in the auditory brainstem. To date, it remains unclear whether these effects remain stable until adulthood and to what degree the amount of exposure to the L2 in early childhood might affect their outcome.We compared three groups of adult English-French bilinguals in their ability to categorize English vowels in relation to their frequency following responses (FFR) evoked by the same vowels. At the time of testing, cognitive abilities as well as fluency in both languages were matched between the (1) simultaneous bilinguals (SIM, N = 18); (2) sequential bilinguals with L1-English (N = 14); and (3) sequential bilinguals with L1-French (N = 11).Our results show that the L1-English group show sharper category boundaries in identification of the vowels compared to the L1-French group. Furthermore, the same pattern was reflected in the FFRs (i.e., larger FFR responses in L1-English > SIM > L1-French), while again only the difference between the L1-English and the L1-French group was statistically significant; nonetheless, there was a trend towards larger FFR in SIM compared to L1-French.Our data extends previous literature showing that exposure to a language during the first years of life induces functional neuroplasticity in the auditory brainstem that remains stable until at least young adulthood. Furthermore, the findings suggest that amount of exposure (i.e., 100% vs. 50%) to that language does not differentially shape the robustness of the perceptual abilities or the auditory brainstem encoding of phonetic categories of the language.Statement of significance:Previous studies have indicated that early age of L2 acquisition induces functional neuroplasticity in the auditory brainstem during processing of the L2. This study compared three groups of adult bilinguals who differed in their age of L2 acquisition as well as the amount of exposure to the L2 during early childhood. We demonstrate for the first time that the neuroplastic effect in the brainstem remains stable until young adulthood and that the amount of L2 exposure does not influence behavioral or brainstem plasticity. Our study provides novel insights into low-level auditory plasticity as a function of varying bilingual experience.

Type of early bilingualism effect on the delateralization of /ʎ/ in Basque and Spanish

Abstract The contrast between /ʎ/ and /ʝ/ has been lost in most Spanish varieties. This merger (yeísmo) has also been claimed to have spread to Basque. I study the palatal merger in Azpeitia Basque and Spanish, where simultaneous (2L1 Basque, Spanish) and early-sequential (L1 Basque, L2 Spanish) groups were tested in both languages. Comparing the two bilingual groups, this study found that, as a group, early-sequential bilinguals do not merge the phonemes in either of the two languages. However, while simultaneous bilinguals maintain the distinction in Basque, they tend to merge the phonemes in Spanish. Inter-speaker variation is found within each group and individual reports do not confirm global results. This study has also encountered different types of speakers as far as the palatal merger is concerned in Basque and Spanish: (1) non-mergers in any of the languages, (2) mergers in both languages, (3) mergers only in Spanish, and (4) mergers only in Basque.

How childhood languages shape future language use and cultural orientation

ABSTRACT In this paper, we investigate the effect that parents’ language use (English, Spanish-English or Spanish) had on self-perceived proficiency, frequency of use, language anxiety, code-switching and cultural orientation of 206 Spanish-English bilinguals and multilinguals who were students in Texas where there is a strong presence of Spanish, the minority language. Our results showed that languages that parents had used with their children had a privileged status: bilinguals and multilinguals reported higher levels of proficiency, more frequent use, less anxiety (except for English) and a stronger cultural orientation. The effect was strongest for parents with Spanish-speaking parents. The scores of the simultaneous bilinguals were generally situated between the scores of the sequential Spanish-English and English-Spanish bilinguals from monolingual families. We conclude that relatively more or less use of a particular language in a family home will lead to significant differences in the grown-up children’s future language use and cultural orientation.

Age of acquisition – not bilingualism – is the primary determinant of less than nativelike L2 ultimate attainment

AbstractIt has recently been suggested that bilingualism, rather than age of acquisition, is what underlies less than nativelike attainment in childhood L2 acquisition. Currently, however, the empirical evidence in favor of or against this interpretation remains scarce. The present study sets out to fill this gap, implementing a novel factorial design in which the variables age of acquisition and bilingualism have been fully crossed. Eighty speakers of Swedish, who were either L1 monolinguals, L1 simultaneous bilinguals, L2 sequential monolinguals (international adoptees), or L2 sequential bilinguals (childhood immigrants), were tested on phonetic, grammatical, and lexical measures. The results indicate consistent effects of age of acquisition, but only limited effects of bilingualism, on ultimate attainment. These findings thus show that age of acquisition – not bilingualism – is the primary determinant of L2 ultimate attainment.
