In countries with several official languages, language separation often remains a structural principle in institutional education. Co-located schools, in which two autonomously administered schools with different languages of instruction share a physical space, may challenge this separation. Such schools have existed for a long time, but…

From early in life, infants synchronize with others on a physiological level, a process thought to underlie social connections and group cohesion. This synchronization is seen, for example, when their pupils dilate in response to observing another person with dilated pupils -- known as "pupillary contagion." There is mixed evidence on…

This study investigated three key issues in heritage language (HL) research. Previous research shows HL speakers have an advantage on oral production tasks compared to L2 speakers who instead perform better on written tasks. Furthermore, both L2 and HL speakers are claimed to have a "yes-bias" towards retaining ungrammaticality in GJTs.…

The study investigates the reflections on tempo-aspectual morphology in Italian expressed by undergraduate multilingual learners with previous knowledge of Swedish and a Romance language (N = 22). The reflections of the participants, who were divided into four groups depending on a combination of proficiency in their background Romance language…

The main goal of this tutorial is to promote the study of children with developmental language disorder (DLD) across different languages of the world. The cumulative effect of these efforts is likely to be a set of more compelling and comprehensive theories of language learning difficulties and, possibly, of language acquisition in general.…

Conversely to plenty of studies describing how L1 transfer affects L2 systems, where the two grammars, L1/L2, often only come to interact later in life, less is known of dominant language transfer in heritage language grammars. Unlike in L2 speakers, the dominant language of the heritage speaker potentially affects its weaker language already from…

With increasing mobility of people across the world, there is a pressing need to develop evidence-based teaching practices that lead to high-quality education, which serves the needs of inclusive societies and social and epistemic justice. This book presents cutting-edge qualitative case-study research across a range of educational contexts,…
