A systems approach to multilingual language attitudes: A case study of Montréal, Québec, Canada.

Purpose: People are shaped holistically by dynamic and interrelated individual and social-ecological systems. This perspective has been discussed in the context of varied aspects of bilingual experiences, namely language acquisition and development. Here, we applied a Systems Framework of Bilingualism to language attitudes, which may be especially responsive to social-ecological influences. Methodology: One hundred twenty-three French-English bilingual adults (M age = 21.20, SD = 3.21) completed self-report questionnaires on demographic information and their attitudes toward languages. A subset of these bilinguals (n = 73) completed a social network survey. Data and analysis: We used language-tagged social network analysis and geospatial demographic analysis to examine the role of individual characteristics (i.e., first language), interpersonal language dynamics (i.e., person-to-person interactions), and ecological language dynamics (i.e., neighborhood language exposure). Findings and Conclusions: At an individual level, we found that bilinguals' language background (i.e., first language) predicted attitudes of solidarity toward a language (i.e., whether a language is associated with personal identity and belongingness). When considering sociolinguistic layers of influence, we found that bilinguals' social network and neighborhood-level language exposure jointly predicted their attitudes of solidarity toward a language, as well as their attitudes toward the protection of minority languages. Originality: While most studies have examined language experience in a unidimensional nature, the present study investigated multilingual language attitudes by considering multiple systems within a social-ecological framework. Implications: Taken together, the results suggest that several interrelated interpersonal and ecological systems are associated with language attitudes, which could have important implications for planning future language policies in multilingual societies such as Montréal.

From One Bilingual to the Next: An Iterated Learning Study on Language Evolution in Bilingual Societies.

Studies of language evolution in the lab have used the iterated learning paradigm to show how linguistic structure emerges through cultural transmission-repeated cycles of learning and use across generations of speakers . However, agent-based simulations suggest that prior biases crucially impact the outcome of cultural transmission. Here, we explored this notion through an iterated learning study of English-French bilingual adults (mostly sequential bilinguals dominant in English). Each participant learned two unstructured artificial languages in a counterbalanced fashion, one resembling English, another resembling French at the phono-orthographic level. The output of each participant was passed down to the next participant, forming diffusion chains of 10 generations per language. We hypothesized that artificial languages would become easier to learn and exhibit greater structure when they were aligned with participants' bilingual experience (i.e., English languages being easier to learn overall), or as a function of practice (i.e., languages learned second being easier to learn overall). Instead, we found that English-like languages became more structured over generations, but only when they were learned first. In contrast, French-like languages became more structured regardless of the order of learning, suggesting the presence of an asymmetric switch cost during artificial language learning. Moreover, individual differences in language usage modulated the amount of structure produced by the participants. Overall, these data suggest that bilingual experience impacts how novel languages are learned at an individual level, which can then scale up to cultural transmission of novel language at a group level.

Something old, something new: A review of the literature on sleep-related lexicalization of novel words in adults.

Word learning is a crucial aspect of human development that depends on the formation and consolidation of novel memory traces. In this paper, we critically review the behavioural research on sleep-related lexicalization of novel words in healthy young adult speakers. We first describe human memory systems, the processes underlying memory consolidation, then we describe the complementary learning systems account of memory consolidation. We then review behavioural studies focusing on novel word learning and sleep-related lexicalization in monolingual samples, while highlighting their relevance to three main theoretical questions. Finally, we review the few studies that have investigated sleep-related lexicalization in L2 speakers. Overall, while several studies suggest that sleep promotes the gradual transformation of initially labile traces into more stable representations, a growing body of work suggests a rich variety of time courses for novel word lexicalization. Moreover, there is a need for more work on sleep-related lexicalization patterns in varied populations, such as L2 speakers and bilingual speakers, and more work on individual differences, to fully understand the boundary conditions of this phenomenon.

Cross-language activation and executive control modulate within-language ambiguity resolution: Evidence from eye movements.

An important question within psycholinguistics is how knowledge of multiple languages impacts the coactivation of word forms and meanings during language comprehension. To the extent that a bilingual's known languages are always partially active, as predicted by models such as the bilingual interactive activation plus model (Dijkstra & Van Heuven, 2002), cross-language activation should influence which meanings are accessed and in which order. Here, we monitored the eye movements of 48 French-English and 40 English-French bilingual adults as they read within-language homonyms embedded in more or less semantically constraining English sentences. The within-language homonyms were either cognate homonyms, whose subordinate meanings were also French cognates (e.g., sage, "herb" or, less frequently, "wise man" in English and, also, "wise man" in French), or uniquely English (e.g., chest). French-English bilinguals processed cognate homonyms with subordinate meanings more quickly than uniquely English homonyms with subordinate meanings, and individual differences in executive control capacity modulated their processing of uniquely English homonyms only. In contrast, English-French bilinguals processed all within-language homonyms similarly, regardless of cognate status and executive control capacity. Our findings suggest that cross-language activation impacts within-language ambiguity resolution by changing the relative dominance of the meanings associated with a word form, and that cross-language activation varies as a function of the language tested (first or second language).
