This paper examines whether adult learners of English whose native languages (Korean and Mandarin Chinese) lack articles are influenced by transfer from demonstratives and numerals in their acquisition of English articles. To this end, the results of two studies are reported. The first study examines native Korean and Mandarin speakers’ preferences for bare vs. non-bare (demonstrative or numeral) forms in different types of definite and indefinite environments. The results of this study give rise to specific predictions for L1-Korean and L1-Mandarin L2-English learners’ sensitivity to article omission errors in different types of definite and indefinite contexts in English. These predictions are tested in the second study, which uses both an offline task (grammaticality judgments) and an online task (self-paced reading) to investigate learners’ sensitivity to errors of article omission. L1-Korean and L1-Mandarin L2-English learners are found to behave very similarly when tested in English, despite different preferences exhibited by native speakers of Korean and Mandarin.  It is concluded that learners of these article-less first languages do not transfer the semantics of demonstratives and numerals onto articles in their second language.

The present study investigated cross-linguistic influence (CLI) in the word order of Dutch-English bilingual children, using elicited production and acceptability judgment tasks. The goal was to examine whether monolingual and bilingual children produced and/or accepted V2 word orders in English, as in * Yesterday painted she an apple. We investigated whether the likelihood of CLI was related to language dominance, age at testing, and the degree of surface overlap (i.e., V2 word orders with auxiliaries versus main verbs).

Even though none of the participants produced V2 word orders in English, in the acceptability judgment task bilingual children were more likely to accept V2 word orders than monolingual peers. Whilst monolinguals sometimes accepted V2 word orders with auxiliaries, bilinguals did so significantly more often (constituting a quantitative difference) and with main verbs, too (implying a qualitative difference). Therefore, we conclude that CLI can occur independently of surface overlap and that it can lead to both quantitative and qualitative differences between bilinguals and monolinguals. The likelihood of CLI was predicted by language dominance, but not by age. Some bilinguals still accepted V2 word orders at age ten, suggesting that in some cases CLI may be more persistent than previously thought.

The term ‘receptive bilingualism/multilingualism’ is used for diverse populations, all of which understand a language without producing speech in it, but differ in the way this receptive ability was achieved and in the linguistic knowledge underlying it. In previous studies, not enough attention is given to the differences between types of receptive bilinguals (RBs); however, a thorough analysis of all types is necessary to understand the nature of receptive bilingualism and, consequently, language comprehension and production in general.

I propose a classification of RBs based on the presence and nature of an acquisition process that led to receptive abilities. In this classification, RBs who comprehend a language mutually intelligible with one they know are distinguished from RBs with acquired knowledge. Within the former, RBs with and without previous exposure are distinguished. Within acquired types, RBs who comprehend a heritage language are distinguished from RBs who comprehend a second/foreign language.

Definite and demonstrative determiners in English share the same central semantics of uniqueness (e.g., Hawkins, 1991 ; Ionin, Baek, Kim, Ko, & Wexler, 2012 ; Wolter, 2006 ), but the computation of the semantics is constrained by different discourse conditions and determined by pragmatic knowledge, which pertains to the interface between semantics and pragmatics. This paper investigates whether L2 learners may have persistent difficulty in acquiring properties involving the semantics-pragmatics interface, by exploring the acquisition of L2 English definite and demonstrative determiners by advanced and near-native L1 Chinese learners of English. It also examines whether acquisition results are influenced by the learners’ L1 Chinese, which lacks an article system but allows demonstrative determiners. The results from a forced-choice written task show that advanced learners were unable to distinguish between the two determiners in different discourse conditions; near-native-level L1 Chinese learners displayed a native-like preference for the definite determiner, but not for the demonstrative determiner. It is argued that convergence at the semantics-pragmatics interface is not impossible for L2 learners, but (un)acquirability may be constrained by asymmetries in the L1–L2 realizations of semantics-pragmatics mappings. The findings raise interesting questions for future research into factors that can influence the acquisition of external interfaces.

Earlier work indicates that bilingualism may positively affect statistical learning, but leaves open whether a bilingual benefit is (1) found during learning rather than in a post-hoc test following a learning phase and (2) explained by enhanced verbal short-term memory skill in the bilinguals. Forty-one bilingual and 56 monolingual preschoolers completed a serial reaction time task and a nonword repetition task (NWR). Linear mixed-effect regressions indicated that the bilinguals showed a stronger decrease in reaction times over the regular blocks of the task than the monolinguals. No group differences in accuracy-based measures were found. NWR performance, which did not differ between the groups, did not account for the attested effect of bilingualism. These results provide partial support for effects of bilingualism on statistical learning, which appear during learning and are not due to enhanced verbal short-term memory. Taken together, these findings add to a growing body of research on effects of bilingualism on statistical learning, and constitute a first step towards investigating the factors which may underlie such effects.

It has been suggested that bilingualism is beneficial for executive control and could have positive long-term effects by delaying the onset of symptoms of degenerative diseases. This research investigates, for the first time, the impact of bilingualism on executive control (monitoring and inhibitory control) in individuals with Multiple Sclerosis (MS), a neurodegenerative disease which commonly causes deficiencies in the cognitive system. Bilingual and monolingual adults, with and without an MS diagnosis, performed a flanker task with two degrees of monitoring demands (high monitoring vs. low monitoring). Results showed that bilingual MS patients had inhibitory control and monitoring abilities that were similar to healthy bilingual controls. In contrast, monolingual MS patients showed similar inhibitory control but significantly worse monitoring abilities compared to monolingual healthy controls. We propose that the similar behaviour between bilingual groups suggests that bilingualism might counteract cognitive deficits related to MS, especially with respect to monitoring. The high monitoring cost observed in monolingual patients seems related to underlying deficits in monitoring and possibly switching, executive control abilities commonly impaired in MS patients from early stages. Our findings provide some preliminary evidence for the cognitive reserve hypothesis in bilingual MS patients.

Child-level factors such as input quantity and quality have received little attention by studies of bilingual language acquisition in situations of societal bilingualism. The present study addresses this gap by investigating the acquisition of quantified partitivity in Catalan-Spanish bilingualism. The two languages present different licensing conditions for noun ellipsis in quantified partitive objects: Catalan requires quantitative clitic en whereas Spanish requires only the quantifier. Bilingual participants (N = 338), ages 4–9, were administered two Oral Production Tasks, one for each language. Analyses of participants’ responses showed that a different combination of child-level factors accounted for their performance in each language, revealing dominance effects. Once participants were classified into three groups (Catalan-dominant, Balanced bilingual, and Spanish-dominant) according to their language dominance, between-group differences were found in each language with respect to the acquisition timeline of the respective structure.

Although SLA research has extensively investigated the role of lexical aspect in L2 acquisition of tense-aspect marking, the role of L1 is not yet fully understood. This paper investigates the effect of cross-linguistic variation in lexical aspect and explores how the learning of lexical aspect interacts with the acquisition of aspectual morphology, using oral picture-description and written judgment tasks. 391 learners of Japanese (L1 English, Chinese, and Korean) participated in the study. The results show that L2 learners have problems in rejecting incorrect L2 aspectual structures (but not in accepting correct ones) when such structures involve L1–L2 discrepancy in lexical aspect. The results also confirmed a strong L1 effect at the level of surface inflected verbal form, showing significantly higher accuracy for items for which direct translation yields correct meaning than those that do not. It is argued that L1 transfer may be playing an important role in the L2 acquisition of aspect in that both positive and negative transfer collectively determine the order of acquisition predicted by the Aspect Hypothesis.

This study investigated the extent to which phonological and orthographic overlap between the two languages of bilinguals predicts word processing abilities in their dominant and non-dominant languages. Forty-four English-dominant L1 English-L2 Spanish speakers and Spanish-dominant Spanish heritage speakers performed a lexical decision task while reading words in English and Spanish. We calculated orthographic and phonological similarity of cognate and noncognate words using the Levenshtein distance measure. Results showed that both bilingual groups benefited from orthographic similarity when reading Spanish and English words, whereas a facilitative effect was restricted to Spanish words that shared phonology across languages. These findings suggest a different contribution of phonological and orthographic similarity in bilingual word recognition, independently of language dominance.

This study investigates restructuring in heritage language (HL) grammars with a special focus on the driving forces behind changes in the underlying grammar. We evaluate the effect of Age of Onset of bilingualism (AoO) on possible grammatical restructuring. Relatedly, we assess whether HL grammar divergence from the baseline can be attributed to the Age of Acquisition of a particular linguistic phenomenon and/or to the structural properties of the dominant language, under transfer.

With these general questions in mind, we conducted an auditory acceptability judgement task evaluating sensitivity to form (mis)matches in adjective-noun and numeral-noun expressions in adult Russian-Hebrew speakers: HL-speakers with AoO before age 5, HL-speakers with AoO between 5–13, and the Russian-dominant bilinguals.

The results demonstrate a robust effect of AoO: HL speakers with earlier AoO are less accurate in detecting ungrammaticalities across the board. We argue that similarities in the structures in the heritage and dominant language allow HL speakers to maintain properties of monolingual grammars; dissimilarities, on the other hand, may lead to reanalysis in the HL grammar. However, the newly-built representations in the HL do not match those of the dominant language, suggesting that changed representations do not result from direct transfer.
