Aiming to shed new light on the discussion on transfer at initial stages of third language (L3) acquisition and development at later stages, this article reports on an empirical study of L3 acquisition of Mandarin temporal-aspectual sentence-final particles (SFPs) le, ne and láizhe by English speaking and English-Cantonese bilingual learners, at both low and high proficiency levels. Cantonese is typologically and structurally closer to Mandarin than English is. Our findings show obvious facilitative effects on le by its Cantonese counterpart in English-Cantonese bilingual learners’ L3 Mandarin, which supports the L3 models that advocate the deterministic role of structural similarity in the transfer source selection. A transfer asymmetry is observed between the cases of le and láizhe. No transfer effects are found in the L3 Mandarin data of láizhe, even though it has an equivalent SFP in Cantonese. This discrepancy is argued to be attributable to input factors and misleading forms. Moreover, patterns observed over different proficiency levels indicate that the quality and quantity of input and the register property of a particular SFP can greatly affect initial transfer and later development of L3 acquisition.

This study investigates the second language (L2) acquisition of a constraint on definiteness in Japanese floating numeral quantifiers (NQs) by native English and Korean speakers. The constraint arises because of the specific structural relation between a floating NQ and its associated noun, resulting in an obligatorily indefinite interpretation. The indirect – or, covert – encoding of definiteness in this structure allows investigation of predictions based on the cline of difficulty proposed by Cho and Slabakova (2014) , whereby L2 acquisition of a covert property may be facilitated if the first language (L1) expresses the relevant feature overtly. English is such a language, having overt morphology to express definiteness, whereas Korean has floating NQs that are obligatorily, and covertly, indefinite, as in Japanese. Sensitivity to definiteness in Japanese floating NQs was measured using an acceptability judgement task. Although both L1-Korean and L1-English speakers of Japanese showed sensitivity to the constraint at group level, follow-up analyses suggested that the Korean group had more consistent knowledge. We argue that the complexity of the acquisition task – which was greater for the English-speakers than the Korean-speakers – played a bigger role in attainment than overt versus covert encoding of the relevant feature in the L1.

The empirical evidence for whether narrative macrostructure skills are shared between a bilingual child’s two languages is inconclusive, and it is not known how macrostructure (overall story structure) is influenced by general language proficiency and amount of exposure. The present study investigates these issues in 100 Turkish-Swedish bilingual 4-to-7-year-old children growing up in Sweden. Oral narratives were elicited in both Turkish and Swedish with two picture-based tasks from the Multilingual Assessment Instrument for Narratives (MAIN) in the telling mode. We investigated to what extent the language of elicitation influences bilingual children’s macrostructure (story structure, episodic complexity), and explored effects of age, narrative task, narrative length, expressive vocabulary and language exposure, both separately and combined, on macrostructure in the respective language. Story structure and episodic complexity were found to increase similarly with age in both Turkish and Swedish from 4 to 7 years. Scores did not differ between the two MAIN storytelling tasks. Expressive vocabulary and narrative length influenced story structure scores positively and similarly in both languages. Daily language exposure and length of exposure to Swedish did not show any significant effect. The results can be interpreted in support of a carry-over of narrative macrostructural skills between the two languages.

Studies of macrostructure in bilingual children investigated potential age and language effects, without systematically taking into account bilingualism factors such as language dominance, exposure to narratives, and general language abilities. These issues were addressed in a study of macrostructure production by 69 bilingual Lebanese Arabic-French children aged 4–9. The children were administered the Multilingual Assessment Instrument for Narratives in the tell mode and a standardized conceptual vocabulary test. Parental questionnaires were also used to gather information on language exposure and use. Age effects and limited effects of language were found for all measures of macrostructure production (story structure, structural complexity and use of internal state terms). Significant correlations arose between these measures, vocabulary scores, and age, and between structural complexity scores and language dominance. Regression analyses revealed the predictive role of vocabulary in the development of macrostructure. These results are compatible with the idea that macrostructure is not language dependent. They also suggest that minimal language skills are needed for expressing macrostructure. The limited impact of bilingualism factors could stem from the fact that French and Lebanese Arabic are majority languages in Lebanon, meaning that the children had received continuous exposure to both languages, including within the school system.

Previous studies have shown that bilingual children typically score more poorly on nonword repetition (NWR) tasks than monolingual peers, which has been attributed to bilinguals’ lower proficiency in the language that the NWR task is based on. To enable fairer assessments of bilingual children, Cross-Linguistic NWR tasks (CL-NWR tasks) have been developed that are based on the linguistic properties of many languages. The aim of this study is to investigate whether young children’s performance on a CL-NWR is less dependent on existing knowledge of a specific language than performance on a Language-Specific (Dutch-based) NWR (LS-NWR). Bilingual and multilingual two- and three-year-olds (N = 216) completed a CL-NWR and LS-NWR, as well as a Dutch receptive vocabulary task. Parents reported the number of languages children spoke other than Dutch. Results of linear mixed-effect regressions showed that Dutch vocabulary scores related to performance on the CL-NWR task less strongly than to performance on the LS-NWR task. The number of non-Dutch languages spoken did not differentially relate to performance on the two tasks. These findings indicate that CL-NWR tasks – at least as used here – allow for more language-neutral NWR assessments within linguistically diverse samples, already at toddler age.

Verbal morphology is a particularly vulnerable domain in the grammars of Spanish heritage speakers (HSs). Among the most frequently studied phenomena is mood selection, identified as a pervasive locus of variability that affects the production of subjunctive more prominently. The present article explores this area of research by examining the effects of mood selection type on HSs’ subjunctive use. In contrast with previous studies, this investigation controls for propositional modality, focusing its analyses on instances of obligatory and variable subjunctive selection within deontic predicates. Results from a production task revealed that, despite the presence of between-group differences driven by participants’ levels of proficiency, type of selection did not significantly modulate their rates of subjunctive use. These findings challenge previous claims about the extent to which this factor affects Spanish HSs’ performance, and highlight the importance of considering propositional modality when examining the acquisition of mood.

While novel and conventional metaphor comprehension has received much attention in the monolingual context, thus far little electrophysiological research has been conducted with a view to examining how bilingual speakers process metaphors in their non-native language (L2) as well as how L2 proficiency level might modulate such processes. The present study aims to investigate the electrophysiological correlates of novel and conventional metaphor comprehension in intermediate and advanced Chinese-English bilingual speakers. The participants performed a semantic decision task to English (L2) novel metaphoric, conventional metaphoric, literal, and anomalous word pairs. The results showed a graded N400 effect from literal utterances, to conventional metaphors, novel metaphors, and finally to anomalous utterances in both groups of participants, indicating that both types of metaphors were more cognitively taxing than literal utterances, irrespectively of L2 proficiency level. Additionally, between-group differences that were irrespective of utterance type were found in the N400 time frame, indicating more extended lexico-semantic access in the intermediate relative to the advanced group. Finally, in both groups of participants, an anterior sustained negativity was found in response to anomalous, novel metaphoric, and conventional metaphoric word pairs, thus suggesting a continuing difficulty of meaning integration.

How parents talk to young children matters to language and cognitive development. In the early years the quantity, quality, and diversity inherent in language from parents in the home predict differences in vocabulary knowledge, school readiness, and later academic achievement. However, most of what is known about child-directed speech (CDS) comes from studies of monolingual parents, and little is known about features of speech from bilingual parents. Here, we asked whether degree of bilingualism assessed within a single parent might be positively associated with CDS features that are known to facilitate children’s lexical and grammatical structures across languages – parental partial repetitions. During unscripted narrations (n = 91) of a picture book to their toddlers in English, mothers who reported being more bilingually balanced used a higher proportion of self-repetitions (both single words and 2-word combinations) within a brief time-frame. At the same time, more bilingual mothers preserved the same degree of lexical diversity as more monolingual mothers. The results obtained even accounting for differences in socio-economic status. These findings are discussed in terms of adaptive strategies that bilingual parents may consciously or unconsciously adopt in bilingual language development

Sound patterns in heritage languages are often highly variable, potentially with influences from majority languages. Yet, the core phonological system of the heritage language tends to remain stable. This article considers variation in the phonetic and phonological patterns of /r/ in American Norwegian heritage language speakers from neighboring communities in western Wisconsin, in the Upper Midwestern United States. Drawing on acoustic data from speakers born between 1879 and 1957, I examine the distribution of four rhotic allophones, including an English-like approximant, over time. These data reveal an increase of approximants that is structured within the Norwegian phonological system and its processes. Furthermore, analyzing these changes with the proposed modular framework provides clarity for how heritage language sound systems do and do not change under contact and contributes to our understanding of the asymmetric phonetic and phonological heritage language patterns.
