Bilingualism is a powerful experiential factor, and its effects have been proposed to extend beyond the linguistic domain by boosting the development of executive functioning skills. Crucially, recent findings suggest that this effect can be detected in bilingual infants before their first birthday indicating that it emerges as a result of early…

Learning about emotions is an important part of children's social and communicative development. How does children's emotion-related vocabulary emerge over development? How may emotion-related information in caregiver input support learning of emotion labels and other emotion-related words? This investigation examined language production and input…

The field of language policy and planning (LPP) has increasingly expanded its focus beyond legislative measures and macro-level policies toward understanding the power of social actors and their interpretation, appropriation, and creation of language policies in societies. This article aims to advance LPP theory and research by offering a critical…

On a 2022 fieldtrip to Ecuador, we encountered a large community of Media Lengua speakers in the province of Cotopaxi where the language was thought to be dormant. This is the same region where Pieter Muysken had first documented this 'mixed language' in the 1970s. However, subsequent fieldwork thereabout by several linguists had failed to turn up…

This article describes the changing linguistic landscape on the North Shore of Vancouver, British Columbia, Canada, during the first three months of the COVID-19 pandemic. I present an account of the visual representation of change along the area's parks and trails, which remained open for socially-distanced exercise during the province's…

Both the amount "and" responsiveness of adult language input contribute to the language development of autistic and non-autistic children. From parent-child interaction footage, we measured the amount of adult language input, overall parent responsiveness, and six discrete parent responsive behaviours ("imitations, expansions,…

The purpose of this study was to better understand multimodal usage in teacher professional learning. Thus, this qualitative phenomenology study was created and executed to better understand how leaders of teacher professional learning understand and implement modes in courses designed for teacher scholarship. Focusing on leader influences,…

The past thirty years have shown a rise in models of language acquisition in which the state of the learner is characterized as a probability distribution over a set of non-stochastic grammars. In recent years, increasingly powerful models have been constructed as earlier models have failed to generalize well to increasingly complex and realistic…

Vocabulary knowledge has been recognized as a crucial component in learning and teaching of both native and non-native learners, text understanding, and educational success (Coxhead, 2018; Saeedi et al., 2023; Schmitt et al., 2021), leading to the development of word lists for different purposes. Hence, this study aimed at developing a newspaper…

The Interface Hypothesis proposes that second language (L2) learners, even at highly proficient levels, often fail to integrate information at the external interfaces where grammar interacts with other cognitive systems. While much early L2 work has focused on the syntax-discourse interface or scalar implicatures at the semantics-pragmatics…

Research in language development has only recently begun to focus on the inherent variability of language. Previous studies have explored at what age children begin to produce variable linguistic forms and how these forms progress through development. While children produce adult-like variation early on, some variable forms take longer to acquire…

This study investigates the use of a popular online expression 'skr' by Chinese micro-blogging users on Weibo. Used originally as a hip-hop term for the sound of cars drifting tires, 'skr' was exploited by Chinese micro-blogging users for other meanings and functions. Data were collected from Weibo users' postings over a month. Using the Search…

Second language acquisition has been observed to be variable in its outcome such that, unlike native speakers, all second language learners do not achieve total success. Second language acquisition is made of macro and micro processes. External and internal (e.g., age, individual differences) factors are assumed to affect language processing in…

This dissertation examines complementizer agreement (CA) phenomena in which phi-features appear on a complementizer, clause-linking marker, or otherwise, syntactically speaking, at the C[superscript 0] position. This dissertation will argue that CA is in fact a straightforward output of the syntax module under standard Minimalist assumptions, and…

In this paper, the role and nature of language and language development will be discussed. Research and theory in second language acquisition has demonstrated that (i) language is an abstract, implicit and complex system. Input (ii) plays a key role in language development; despite the fact that some knowledge of language is innate (iii). Overall,…
