Title: Multiple grammars within linguistic populations: Distributions and theoretical implications
Abstract This paper explores the concept of multiple grammars (MGs) and their implications for linguistic theory, language acquisition, and bilingual language knowledge. Drawing on evidence from phenomena such as scope interactions, verb raising, and agreement patterns, I argue that seemingly identical surface structures can be undergirded by different grammatical analyses that may compete within speaker populations. I then propose a typology of MG distributions, includingshared MGs, competing MGs,andpartial MGs, each with distinct consequences for acquisition and use. Contrary to expectations of simplification, bilingualism can sometimes lead to an expansion of grammatical analyses and does not always lead to the elimination of MGs. The paper discusses methods for predicting environments conducive to MGs, considering factors such as structural ambiguity and silent elements. The examination of MGs compels us to explore how learners navigate underdetermined input, especially in bilingual contexts, and to examine the interplay between gradient acceptability judgments and categorical grammatical distinctions. The study of MGs offers valuable insights into language variation, change, and the nature of linguistic competence.  more » « less

  1. Abstract Although language awareness is typically defined as the explicit understanding of language's functions and conventions, much evidence on the influence of diverse language environments on language awareness has shown implicit understandings of language. In contrast, this study examined whether exposure to linguistic diversity predicted monolingual children's explicit language awareness. We examined four aspects of children's explicit language awareness: ability to label languages, understanding of the communicative consequences of speaking different languages, understanding of labeling conventions, and awareness of their language environment. Participants were monolingual 3‐ to 5‐year‐olds (N= 81) who were from (a) a relatively linguistically homogenous community, (b) a relatively linguistically diverse community, or (c) a bilingual household in a relatively linguistically diverse community. Results suggest that community linguistic diversity and home bilingual exposure predict children's explicit language labeling and understanding of labeling conventions but not other aspects of language awareness. These findings provide insight into the role of early language environments in explicit language awareness development.

    Modern deep neural networks achieve impressive performance in engineering applications that require extensive linguistic skills, such as machine translation. This success has sparked interest in probing whether these models are inducing human-like grammatical knowledge from the raw data they are exposed to and, consequently, whether they can shed new light on long-standing debates concerning the innate structure necessary for language acquisition. In this article, we survey representative studies of the syntactic abilities of deep networks and discuss the broader implications that this work has for theoretical linguistics.

    Our research team performed an exploratory analysis of teacher gesturing via a case study of an elementary teacher. We focused on gesturing, a practice found to support both bilingual English learner students’ linguistic development and mathematics achievement, during the teacher’s engineering and science lessons. The research team systematically analyzed teacher video data using McNeill’s gestural dimensions framework and found variation of gesturing types and rates when comparing engineering and baseline science lessons. Additionally, specific types of teacher-gestures appear to be associated with either behavioral or classroom management practices, procedural instructions, and discussion facilitation. We suggest that teacher-gestures such as these have the potential to facilitate bilingual English learners’ language acquisition, while also developing their STEM literacy in general and engineering capacity in particular. Further exploration of teacher-gestures in elementary engineering curricula could lead to an integrated STEM pedagogy that incorporates gesturing as a fundamental teaching strategy, bridging STEM instruction with linguistically responsive instructional practices.

  4. Abstract Cross-linguistic interactions are the hallmark of bilingual development. Theoretical perspectives highlight the key role ofcross-linguistic distancesandlanguage structurein literacy development. Despite the strong theoretical assumptions, the impact of such bilingualism factors in heritage-language speakers remains elusive given high variability in children's heritage-language experiences. A longitudinal inquiry of heritage-language learners of structurally distinct languages – Spanish–English and Chinese–English bilinguals (N= 181,Mage= 7.57, measured 1.5 years apart) aimed to fill this gap. Spanish–English bilinguals showed stronger associations between morphological awareness skills across their two languages, across time, likely reflecting cross-linguistic similarities in vocabulary and lexical morphology between Spanish and English. Chinese–English bilinguals, however, showed stronger associations between morphological and word reading skills in English, likely reflecting the critical role of morphology in spoken and written Chinese word structure. The findings inform theories of literacy by uncovering the mechanisms by which bilingualism factors influence child literacy development.

  5. Recognizing the challenges bilingual children face in school readiness and the potential of bilingual dialogic shared reading in improving language and literacy, this study investigates the use of a bilingual conversational agent (CA) to enhance shared reading experiences in home environments. While current CAs hold promise in fostering young children's learning, they do not typically consider the linguistic and cultural needs of bilingual children and rarely involve parents intentionally. To this end, we developed a bilingual CA, embedded within ebooks, to support children's language learning and parent engagement for Latine Spanish-English bilingual families. A week-long home-based study with 15 families indicated that the bilingual CA elicited a high level of bilingual verbal engagement from children, thereby promoting their vocabulary acquisition. It also stimulated meaningful conversations among parents and children. This study provides design implications for developing CAs for bilingual children and parents.
