I see what you mean: Semantic but not lexical factors modulate image processing in bilingual adults.

Bilinguals frequently juggle competing representations from their two languages when they interact with their environment (i.e., nonselective activation). As a result, both first (L1) and second language (L2) communication may be impeded when words share orthographic form but not meaning (i.e., interlingual homographs; e.g., CRANE, a machine in English, a skull in French). Similarly, bilinguals' reduced exposure to each known language makes bilingual lexical processing more vulnerable to larger frequency effects. While much is known about processes within the language system, less is known about how the bilingual language system interacts with the visual system, specifically in the context of image processing. We investigated this by testing whether commonly observed semantic (homograph interference) and lexical (frequency) effects extend to a visual word-image matching task. We tested 48 bilinguals, who were asked to determine whether an image corresponded to a written word that was presented immediately beforehand. By modulating the complexity of visual referents and the semantic (Analysis 1) or lexical (Analysis 2) complexity of word cues, we simultaneously burdened the visual and language systems. The results showed that both semantic and lexical factors modulated response accuracy and correct reaction time on the word-image matching task. Crucially, we observed an interaction between the image factor (visual complexity) with the semantic (homograph status) but not the lexical factor (word frequency). We conclude that it is possible for the language and image processing systems to interact, although the extent to which this occurs depends on the degree of linguistic processing involved.

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.
