This study investigated the effects of the amount of cumulative heritage language (HL) exposure during three time periods, on heritage and majority language performance in young adulthood, among two distinct groups of immigrant populations in the USA. Within each time period, exposure from three different sources were examined, and amount of cumulative exposure was calculated encompassing exposure from preceding periods. Factors that may modulate exposure effects were also assessed. Results showed that greater cumulative HL exposure from people at home during all three time periods significantly predicted HL skills for both language groups. For effects on English skills, only the Spanish group showed any influences of exposure. These effects were modulated by parental English proficiency. Input from other sources had less impact. The present findings support the role of parental input throughout childhood, adolescence, and early adulthood in improving HL skills, with less noticeable consequences for the majority language.

This study examines the influence of previously acquired languages – namely, Colloquial Arabic (CA) and English – on the acquisition of Standard Arabic (SA) by L3 and L2 learners. It reports on the role of typological and structural proximity in language transfer and whether transfer patterns change over time. The study involved 105 participants: 41 CA-L1, English-L2 learners of SA, 47 English-L1 learners of SA, and 17 Arabic-L1 speakers. The participants completed three written tasks focusing on: definite article use, verb subcategorization rules, and sentential negation. The results indicate that CA plays a positive role in L3 learners’ acquisition of SA, mainly in forms where SA and CA converge, whereas English seems to play more of a negative role for both L3 and L2 learners. Thus, structural proximity seems to play a positive role in transfer to the L3. Negative transfer, irrespective of proximity/distance, diminishes as learners advance in their study of SA.

We measured mutual intelligibility of 16 closely related spoken languages in Europe. Intelligibility was determined for all 70 language combinations using the same uniform methodology (a cloze test). We analysed the results of 1833 listeners representing the mutual intelligibility between young, educated Europeans from the same 16 countries.

Lexical, phonological, orthographic, morphological and syntactic distances were computed as linguistic variables. We also quantified non-linguistic variables (e.g. exposure, attitudes towards the test languages). Using stepwise regression analysis the importance of linguistic and non-linguistic predictors for the mutual intelligibility in the 70 language pairs was assessed.

Exposure to the test language was the most important variable, overriding all other variables. Then, limiting the analysis to the prediction of inherent intelligibility, we analysed the results for a subset of listeners with no or little previous exposure to the test language. Linguistic distances, especially lexical distance, now explain a substantial part of the variance.

Bilingual language control has previously been tested separately in tasks of language comprehension and language production. Whereas these studies have suggested that local control processes are selectively recruited during mixed-language production, the present study investigated whether measures of global control show the same dependence on modality, or are shared across modalities. Thirty-eight Dutch-French bilingual young adults participated by completing two tasks of bilingual language control in both modalities. Global accuracy on mixed-language comprehension was related to mixing costs on bilingual verbal fluency, but only when compared to the L2-baseline. Global performance on mixed-language production was related to forward (L1-to-L2) switch costs. Finally, a significant correlation was found between the mixing cost on verbal fluency and forward switch costs on the comprehension task. The results are interpreted as evidence for the involvement of monitoring processes in bilingual language control across modality. The results also highlight the relevance of language switch directionality.

Early Spanish-English bilinguals and English controls were tested on the production and perception of negative, short-lag, and long-lag Voice Onset Time (VOT), VOT types spanning the Spanish and English phonetic categories: phonologically, negative and short-lag VOT stops are distinct phonemes in Spanish, but realizations of voiced stops in English. Dominance was critical: more English-dominant bilinguals produced more short-lag VOT stops in response to negative VOT stimuli, and were also less accurate than more balanced bilinguals at discriminating negative from short-lag VOT. Bilinguals performed similarly to monolinguals overall, but they produced more negative VOT tokens and shorter short-lag VOT in response to negative VOT. Their productions were also less well correlated with perception and showed more variation between individuals. These results highlight the variable nature of bilingual production and perception, and demonstrate the need to consider language dominance, individual variation, as well as modalities and tasks when studying bilinguals.

In Papiamento-Dutch bilingual speech, the nominal construction is a potential ‘conflict site’ if there is an adjective from one language and a noun from the other. Adjective position is pre-nominal in Dutch (cf. rode wijn ‘red wine’) but post-nominal in Papiamento (cf. biña kòrá ‘wine red’). We test predictions concerning the mechanisms underpinning word order in noun-adjective switches derived from three accounts: (i) the adjective determines word order ( Cantone & MacSwan, 2009 ), (ii) the matrix language determines word order ( Myers-Scotton, 1993 , 2002 ), and (iii) either order is possible ( Di Sciullo, 2014 ). An analysis of spontaneous Papiamento-Dutch code-switching production ( Parafita Couto & Gullberg, 2017 ) could not distinguish between these predictions. We used event-related brain potentials (ERPs) to measure online comprehension of code-switched utterances. We discuss how our results inform the three theoretical accounts and we relate them to syntactic coactivation and the production-comprehension link.

This study investigates 37 child heritage speakers’ direct object (DO) clitics in Spanish. Results from a production task show that DO expression versus omission was related to Spanish vocabulary: the lower the vocabulary score, the more omitted DOs. In contrast, DO clitic gender was related to English: children who used more English in the home and who had higher English vocabulary scores produced more gender mismatches, most notably lo referring to feminine referents. Results from a comprehension task suggest that children do not attend to clitic gender for referent identification. We argue that the disambiguation function of DO clitic gender, which is infrequent in discourse, may take a long time to develop. Overall, the study suggests that the extent to which restricted input and crosslinguistic influence affect child heritage speakers’ minority language grammar may be mediated by the nature of the linguistic phenomenon in question.

The present study explores the acquisition of the Russian accusative [acc] case inflections in two groups of bilingual children (Russian-Dutch and Russian-Hebrew) who acquire Russian as their Heritage Language (HL) and two groups of monolingual Russian-speaking children within the Unified Competition Model ( MacWhinney, 2008 , 2012 ). Seventy-two typically developing children participated in the study. Children’s performance on three tasks was compared: elicited production, forced-choice comprehension and sentence repetition.

The current study confirmed the predictions of the Unified Competition Model: monolingual children view the [acc] case inflection as a reliable cue. Conversely, bilingual children showed lower accuracy on nouns which require the use of a dedicated [acc] marker. Similarly, the percentage of children manifesting sensitivity to [acc] case cue was low in bilinguals. The findings of the study extend the Unified Competition Model to patterns of HL acquisition in bilinguals. Cue detection in HL for bilinguals is challenged when exposure is limited.

We investigate reference production in bilingual children. Based on Kibrik (2011) , we analyze the production of referring expressions in discourse in terms of activation of a referent. We propose a novel approach, which calculates activation by taking into account different activation-lending factors and their respective weight. This allows us to compare the activation encoded by referring expressions across languages and groups of speakers, and to run correlational analyses with the speakers’ cognitive profiles. In particular, the study addresses the correlation between activation and lexical processing among bilinguals, based on the distribution of referring expressions in narratives by 20 German-Greek bilingual children, compared to their monolingual peers. We found that bilingual pronouns correspond to a lower activation than monolingual ones. Speed of lexical retrieval is a predictor of the bilingual performance. Our model of analysis accounts for how reference production varies across individuals and which cognitive mechanisms underlie this variation.

Research focused on the cognitive processes surrounding bilingual language representation has revealed the important role that translation ambiguity plays in how languages are stored in memory ( Tokowicz & Kroll, 2007 ). In addition, translation of emotionally related information has been shown to be challenging because a direct translation does not always exist ( Basnight-Brown & Altarriba, 2014 ). The focus of the current study was to explore the processing of ambiguous words for translations that differ in orthography. In Experiment 1, Chinese-English bilinguals translated concrete and abstract words that differed in the number of translations across languages. In Experiment 2, emotion words were introduced into the context, in order to examine differences in emotion translation across languages. The results revealed that words with a single translation were produced faster and more accurately than words that had multiple translations. Finally, translation of emotional stimuli was faster when translating Chinese words as compared to English words.
