Evidence suggests that cultural experiences and learning multiple languages have measurable effects on children's development of executive function (EF). However, the precise impact of how bilingualism and culture contribute to observed effects remains inconclusive. The present study aims to investigate how these factors shape the development of early EF constructs longitudinally, between monolingual and bilingual children at ages 3, 3½ and 4 years, with a set of EF tasks that are uniquely relevant to the effects of bilingualism and cultural practices. We hypothesize that the effects of bilingualism and cultural backgrounds (i.e., Eastern) are based on different, though related, cognitive control processes associated with different EF constructs. Results revealed a significant bilingualism effect on cognitive control processes measuring selective attention, switching, and inhibition; while an effect of culture was most pronounced on behavioral regulation/response inhibition. Contributions of bilingualism and cultural experiences on individual EF constructs across development are discussed.

Cross-language (L1-to-L2) syntactic priming is the repetition of utterance structure from one language to another independently of meaning and has motivated models of language-shared representations of L1-L2 equivalent structures (Salamoura and Williams, submitted; Schoonbaert, Hartsuiker and Pickering, submitted). These models assume that the phenomenon is the result of residual activation of syntactic features encoding verb structural preferences and they, therefore, predict its initiation by a single verb prime (cf. Pickering and Branigan, 1998, for L1). This prediction was confirmed in a sentence completion task where we obtained syntactic priming from L1 Dutch to L2 English with Prepositional Object (PO) and Double Object (DO) datives upon presentation of single Dutch verbs that take either PO or DO only.

The current study set out to examine word recognition in early fluent Spanish–English bilinguals using a single word presentation lexical decision task (LDT). Reaction times (RTs) and event-related brain potentials (ERPs) were measured while subjects (16 per language condition) made a lexical decision on words and pseudowords in either Spanish or English. Results show associative priming as measured by RTs, but both associative and categorical priming in the ERPs in both language conditions. The dissociation of RT and ERP effects suggests that the two measures might tap into different underlying processes during semantic priming or reflect different sensitivities towards semantic priming. Furthermore, both RT and ERP measures revealed symmetrical priming in L1 and L2. These data indicate that word recognition in early fluent bilinguals is equivalent for L1 and L2.

Maze use appears to be higher in bilingual speakers than in their functionally monolingual peers. One question is whether this is due to the speaker's bilingual status or to the characteristics of the bilingual's language(s). Narratives for 22 Spanish–English bilingual 4–6-year-olds and their functionally monolingual age-matched peers were analyzed for maze use. Bilingual and functionally monolingual children used similar percentages and patterns of mazes. Children produced more grammatical revisions in Spanish than English. Bilingual and functionally monolingual children used similar grammatical revision strategies in Spanish and English. Children's maze use in each language was correlated with measures of language productivity such as mean length of utterance and number of words used in the sample. These findings suggest that the role of language is important in maze use and that bilingual children do not necessarily have greater levels of linguistic uncertainty than do their functionally monolingual peers.

In introducing this special issue of Bilingualism: Language and Cognition, we feel it is critical to clarify what we understand ‘linguistic convergence’ to mean in the context of bilingualism, since ‘convergence’ is a technical term more readily associated with the field of language contact than with the field of bilingualism (for recent discussions of the role of convergence in contact see Thomason and Kaufman, 1988; Thomason, 2001; Myers-Scotton, 2002; Clyne, 2003; Winford, 2003). Within the language contact literature, the term invites a variety of uses. Some researchers adopt a definition of convergence that requires that all languages in a contact situation change, sometimes to the extent that the source of a given linguistic feature cannot be determined (see April McMahon's commentary in this issue). For others, convergence may be more broadly defined to also apply to situations in which one language has undergone structural incursions of various sorts from contact with another.

The performance of bilingual children and adults in Wales on Welsh and English vocabulary and grammar and on cognitive measures is re-analysed in relation to SES indicators of parental education and parental professions. Results are reported for 732 participants ranging across seven age groups from age 3 to over 60 and from four home language types, monolingual English, and bilinguals with only English at home, Welsh and English at home, or only Welsh at home. Results reveal extensive evidence of SES influence on performance, and of a complex relation of exposure in the home and SES level on performance, modulated by the age of the participant and whether one is considering the majority or minority language.

This study aims to examine the influence of multiple translations of a word on bilingual processing in three translation recognition experiments during which French–English bilinguals had to decide whether two words were translations of each other or not. In the first experiment, words with only one translation were recognized as translations faster than words with multiple translations. Furthermore, when words were presented with their dominant translation, the recognition process was faster than when words were presented with their non-dominant translation. In Experiment 2, these effects were replicated in both directions of translation (L1–L2 and L2–L1). In Experiment 3, we manipulated number-of-translations and the semantic relatedness between the different translations of a word. When the two translations of a word (i.e., bateau) were related in meaning (synonyms such as the English translations boat and ship), the translation recognition process was faster than when the two translations of a word (i.e., argent) were unrelated in meaning (the two translations money and silver). The consequences of translation ambiguities are discussed in the light of the distributed conceptual feature model of bilingual memory (De Groot, 1992b; Van Hell and De Groot, 1998b).

Spanish phonological development was examined in six sequential bilingual children at the point of contact with English and eight months later. We explored effects of the English vowel and consonant inventory on Spanish. Children showed a significant increase in consonant cluster accuracy and in vowel errors. These emerging sequential bilingual children showed effects of English on their first language, Spanish. Cross-linguistic transfer did not affect all properties of the phonology equally. Negative transfer may occur in specific areas where the second language is more complex, requiring reorganization of the existing system, as in the transition from the Spanish five-vowel to the English eleven-vowel system.

This article studies the acquisition of copulas by a Spanish–English bilingual between the ages of 1;6 and 3;0, examines the possibility of interlanguage influence, and considers the distributional frequencies of copular constructions in the speech of the child and in the language input from adults. The study is of interest because the bilingual child needs to acquire semantic and syntactic contrasts in Spanish that are not explicitly marked in English. This difference raises questions about the timing of acquisition of the Spanish copulas under pressure from a stronger language, in addition to the language-internal questions concerning the acquisition of the semantics and syntax of these verbs. The results show that copular constructions develop autonomously, but with a slight delay in the acquisition of estar interpreted as a possible type of influence from English. The distributional analysis reveals parallels between the child's and the adults' uses of copulas, thus supporting a process of acquisition guided by the nature of the interactions that the child enters into with the adults who surround him.

This study investigated the extent to which cognitive abilities that involve explicit cognitive processes (i.e., explicit language aptitude) are related to second language (L2) learning outcomes under two corrective feedback conditions. The study followed a pretest-posttest-delayed posttest experimental design. Forty-eight L2 learners of English carried out three oral production tasks, in which their errors on the indefinite article were treated according to their group assignment (i.e., explicit, implicit, and no-feedback). A set of controlled oral production tests was administered as pretest and posttest. Explicit language aptitude was measured using three subtests from the LLAMA Language Aptitude Test battery (Meara, 2005). Results showed that explicit language aptitude predicted immediate posttest performance only under the explicit feedback condition, suggesting that this type of feedback requires mental processes that are facilitated by explicit cognitive abilities and that its short-term effectiveness is not the same for learners with different aptitude levels.

When speakers describe motion events using different languages, they subsequently classify those events in language-specific ways (Gennari, Sloman, Malt & Fitch, 2002). Here we ask if bilingual speakers flexibly shift their event classification preferences based on the language in which they verbally encode those events. English–Spanish bilinguals and monolingual controls described motion events in either Spanish or English. Subsequently they judged the similarity of the motion events in a triad task. Bilinguals tested in Spanish and Spanish monolinguals were more likely to make similarity judgments based on the path of motion versus bilinguals tested in English and English monolinguals. The effect is modulated in bilinguals by the age of acquisition of the second language. Late bilinguals based their judgments on path more often when Spanish was used to describe the motion events versus English. Early bilinguals had a path preference independent of the language in use. These findings support “thinking-for-speaking” (Slobin, 1996) in late bilinguals.

In everyday communication, speakers make use of a variety of contextual and gestural cues to modulate the meaning of an utterance. Young children have difficulty in integrating multiple communicative cues when some of them have to be interpreted differently depending on other co-occurring cues. However, bilingual children, who regularly experience communicative challenges that demand greater attention and flexibility, may be more adept in integrating multiple cues to understand a speaker's communicative intent. We replicated Nurmsoo and Bloom's (2008) procedure with three-year-old monolingual and bilingual children using a procedure in which they saw two novel objects while the experimenter could see only one. The experimenter looked at the object she could see and said either “There's the [novel-word!]” or “Where's the [novel-word]?”. Compared to monolinguals, bilingual preschoolers were better able to integrate the semantics of “where”, perceptual access of the experimenter, and the nonlinguistic context of the game to successfully differentiate the speaker's communicative intent.

Valian (2014) suggests that the messy state of the literature examining the effects of bilingualism on executive functioning (EF) stems from lack of clarity in how EFs are defined and measured, and from lack of control over other factors that can modulate EF. We argue that the lack of clarity in how bilingualism is defined and measured is no less problematic. We focus our commentary on two related issues.

In this paper we discuss three areas of development that have been shown to be fundamental to the acquisition of literacy. These areas are experience with stories and book reading, concepts of print, and phonological awareness. In each area, we review the research comparing the development of these skills by bilingual and monolingual children. In all three areas, research has been contradictory regarding whether or not bilingual children differ from their monolingual peers. We attempt to reconcile some of these diverse findings by identifying more specifically the effects that bilingualism has on children's early literacy development.

Neural plasticity in speech acquisition and learning is concerned with the timeline trajectory and the mechanisms of experience-driven changes in the neural circuits that support or disrupt linguistic function. In this selective review, we discuss the role of phonetic learning in language acquisition, the “critical period” of learning, the agents of neural plasticity, and the distinctiveness of linguistic systems in the brain. In particular, we argue for the necessity to look at brain–behavior connections using modern brain imaging techniques, seek explanations based on measures of neural sensitivity, neural efficiency, neural specificity and neural connectivity at the cortical level, and point out some key factors that may facilitate or limit second language learning. We conclude by highlighting the theoretical and practical issues for future studies and suggest ways to optimize language learning and treatment.

This study investigates whether late second/foreign language (L2) learners can rely on mechanisms similar to those of native speakers for processing morphologically complex words. Specifically, it examines whether native English speakers who have begun learning French around the onset of puberty can decompose -er (Class I) French verbs. Mid-to-high-proficiency L2 learners and native French speakers completed a masked-priming word-naming task. Latencies for morphologically related, orthographically related, and semantically related prime–target combinations were compared to latencies for identical and unrelated prime–target combinations. The results reveal the following effects: full morphological priming for both native and non-native speakers, with this effect increasing with French proficiency for L2 learners; partial orthographic priming for both groups; greater priming in the morphological condition than in the orthographic condition for both groups; and no semantic priming for either group. We conclude that L2 learners have access to similar mechanisms to those of native speakers for processing morphologically complex words.

Although variation in the ways individuals process language has long been a topic of interest and discussion in the psycholinguistic literature, only recently have studies of bilingualism and its cognitive consequences begun to reveal the fundamental dynamics between language and cognition. We argue that the active use of two languages provides a lens through which the interactions between language use, language processing, and the contexts in which these take place can be fully understood. Far from bilingualism being considered a special case, it may provide the common basis upon which the principles of language learning and use can be modeled.

This study aimed to examine the so-called bilingual advantage in older adults’ performance in three cognitive domains and to identify whether language use and bilingual type (dominant vs. balanced) predicted performance. The participants were 106 Spanish–English bilinguals ranging in age from 50 years to 84 years. Three cognitive domains were examined (each by a single test): inhibition (the Simon task), alternating attention (the Trail Making test), and working memory (Month Ordering). The data revealed that age was negatively correlated to performance in each domain. Bilingual type – balanced vs. dominant – predicted performance and interacted with age only on the inhibition measure (the Simon task). Balanced bilinguals showed age-related inhibition decline (i.e., greater Simon effect with increasing age); in contrast, dominant bilinguals showed little or no age-related change. The findings suggest that bilingualism may offer cognitive advantage in older age only for a subset of bilinguals.

Many attempts have been made to teach native Japanese listeners to perceptually differentiate English /r–l/ (e.g. rock–lock). Though improvement is evident, in no case is final performance native English-like. We focused our training on the third formant onset frequency, shown to be the most reliable indicator of /r–l/ category membership. We first presented listeners with instances of synthetic /r–l/ stimuli varying only in F3 onset frequency, in a forced-choice identification training task with feedback. Evidence of learning was limited. The second experiment utilized an adaptive paradigm beginning with non-speech stimuli consisting only of /r/ and /l/ F3 frequency trajectories progressing to synthetic speech instances of /ra–la/; half of the trainees received feedback. Improvement was shown by some listeners, suggesting some enhancement of /r–l/ identification is possible following training with only F3 onset frequency. However, only a subset of these listeners showed signs of generalization of the training effect beyond the trained synthetic context.

Cross-language priming is a widely used experimental paradigm in psycholinguistics to study how bilinguals’ two languages are represented and organized. Researchers have observed a number of interesting patterns from the priming effects of both translation equivalents and semantically related word pairs across languages. In this study, we implement a self-organizing neural network model, DevLex–II, to simulate these two types of priming effects across Chinese and English. Specifically, our model incorporates a computational mechanism for simulating spreading activation based on the distance between bilingual words in the semantic space. The model also considers additional factors that modulate priming effects, such as the initial activation level of the prime words and the degree to which the target word can be recognized. Our model reveals differences with respect to the priming effects as a function of bilingual type (early versus late L2 learners), directions of priming (L1 to L2 versus L2 to L1), and types of priming (translation versus semantic priming). These simulated differences are compared with empirical findings from previous studies and discussed in the light of interactive and developmental theories of bilingual lexical representation.
