As I write the introduction to my penultimate volume of the Annual Review of Applied Linguistics, I find myself grateful for three aspects of the job. First, I have learned so much about research that I did not know existed, in the case of this issue, linguistic landscape research. Second, I am grateful for colleagues who, while experts in their specific areas, have an amazing breadth of knowledge of the field of applied linguistics. Such individuals are rare finds, and I am lucky to have several such people on my editorial board. Finally, I would not be able to put together issues on certain topics without the help of colleagues whom I have called upon for brainstorming sessions. I am thankful for colleagues who are so willing to help. For this issue, I thank, in particular, Jasone Cenoz.

This article looks at the definitions and scope of multilingualism and the different perspectives used in its study. Multilingualism is a very common phenomenon that has received much scholarly attention in recent years. Multilingualism is also an interdisciplinary phenomenon that can be studied from both an individual and a societal perspective. In this article, several dimensions of multilingualism are considered, and different types of multilingualism are discussed. The article summarizes the themes researched in various areas of the study of multilingualism such as neurolinguistics, psycholinguistics, linguistics, education, sociolinguistics, and language policy. These areas look at language acquisition and language processing as well as the use of different languages in social contexts and adopt a variety of research methodologies. The last section of the article compares monolingual and holistic perspectives in the study of multilingualism, paying special attention to new approaches developed in the past few years that argue for establishing more fluid boundaries between languages.

Multilingual first language acquisition refers to the language development of children exposed to two or more languages from birth or shortly thereafter. Much of the research on this topic adopts a comparative approach. Bilinguals are thus compared with their monolingual peers, and trilinguals with both bilinguals and monolinguals; within children, comparisons are made between a child's two (or more) languages, and between different domains within those languages. The goal of such comparisons is to determine the extent to which language development proceeds along similar paths and/or at a similar rate across groups, languages, and domains, in order to elaborate upon the question of whether these different groups acquire language in the same way, and to evaluate how language development in multilingual settings is influenced by environmental factors. The answers to these questions have both theoretical and practical implications.

The goal of this article is to discuss the results of some of this recent research on multilingual first language acquisition by reviewing (a) properties of the developing linguistic system in a variety of linguistic domains and (b) some of the characteristics of multilingual first language acquisition that have attracted attention over the past five years, including cross-linguistic influence, dominance, and input quantity/quality. Trilingual first language acquisition is covered in a dedicated section.

The goal of this article is to introduce the reader to contemporary adult multilingual acquisition research within generative linguistics. In much the same way as monolingual and bilingual acquisition studies are approached within this paradigm, generative multilingual research focuses primarily on the psycholinguistic and cognitive aspects of the acquisition process. Herein, we critically present a panoramic view of the research questions and empirical work that have dominated this nascent field, taking the reader through several interrelated epistemological discussions that are at the vanguard of contemporary multilingual morphosyntax work. We finish this article with some thoughts looking towards the near future of adult multilingual acquisition studies.

Over the last decade, research on multilingualism has grown and has provided researchers with new insights into the mechanisms at work in the multilingual brain. While some studies of multilinguals have shown similar results to what has been seen in studies of bilinguals, certain unique properties of multilinguals are beginning to be noticed, particularly regarding early language representation, gray matter density, and speed of lexical retrieval. In addition, research on cognitive control, language switching, working memory, and certain consequences of multilingualism (advantages and disadvantages) are reviewed in terms of their effects on the brains of bilinguals and multilinguals. Although there is little agreement among papers concerning specific regions that are structurally different in monolinguals and multilinguals, publications do show differences. Similarly, there are studies reporting somewhat different regions called upon for processing a given language in multilinguals compared to monolinguals.

Recent studies have shown that when bilinguals or multilinguals read written words, listen to spoken words, or plan words that they intend to speak in one language alone, information in all of the languages that they know is momentarily active. That activation produces cross-language competition that sometimes converges to facilitate performance and sometimes diverges to create costs to performance. The presence of parallel activation across languages has been documented in comprehension, in studies of word recognition, and also in production, in studies of lexical speech planning. The observation that one of the two or more languages cannot be switched off at will is particularly surprising in production, where the intention to express a thought should be guided by conceptually driven processes. Likewise, in comprehension, recent studies show that placing words in sentence context in one language alone is insufficient to restrict processing to that language. The focus of current research on the multilingual lexicon is therefore to understand the basis of language nonselectivity, to consider how the language in use is ultimately selected, and to identify the cognitive consequences of having a lexical system that is open to influence by the languages not in use. In this article, we review the recent cognitive and neural evidence on each of these issues, with special consideration to the question of how the nature of the evidence itself shapes the conclusions drawn about the organization and access to the lexicon in individuals who speak more than one language.

We review the characteristics of developmental language disorders (primary language impairment, reading disorders, autism, Down syndrome) and acquired language disorders (aphasia, dementia, traumatic brain injury) among multilingual and multicultural individuals. We highlight the unique assessment and treatment considerations pertinent to this population, including, for example, concerns of language choice and availability of measures and of normative data in multiple languages. A summary of relevant, recent research studies is provided for each of the language disorders selected.

This survey article presents studies on multilingualism in the workplace carried out in different regions. One aim is to give a cross-cultural picture of workplace studies on different languages, and another is to discuss both positive and problem-based accounts of multilingualism at work. The conditions for workplace discourse have been influenced by a series of changes taking place in recent decades. Technological advances have led to new types of networks and workplaces, making linguistic issues salient, at the same time as many low-paid workers are found in traditional jobs, for which the face-to face interaction is central. A model is presented, the aim of which is to grasp the complex and dynamic interplay between workplace discourse and its various contextual frames. Overviews of studies on multilingualism at work are discussed with a focus on workplaces in the inner, outer, and expanding English circles; in transnational companies; and in multilingual regions and English lingua franca workplaces in Europe. Workplaces with workforce diversity are also dealt with. In the discussion section, the scope is enlarged and workplace discourse is related to various contextual frameworks. Finally, some key topics for future studies are sketched.

This article offers an overview of the main developments in the field of linguistic landscape studies. A large number of research projects and publications indicate an increasing interest in applied linguistics in the use of written texts in urban spaces, especially in bilingual and multilingual settings. The article looks into some of the pioneer studies that helped open up this line of research and summarizes some of the studies that created the springboard for its rapid expansion in recent years. The focus is on current research (from 2007 onward), including studies that illustrate main theoretical approaches and methodological development as key issues of the expanding field, in particular when applied in settings of societal multilingualism.

Publications on the linguistic landscape cover a wide range of innovative theoretical and empirical studies that deal with issues related to multilingualism, literacy, multimodality, language policy, linguistic diversity, and minority languages, among others. The article shows some examples of the use of the linguistic landscape as a research tool and a data source to address a number of issues in multilingualism. The article also explores some possible future directions. Overall, the various emerging perspectives in linguistic landscape research can deepen our understanding of languages in urban spaces, language users, and societal multilingualism in general.

Multilingual education policy has been a controversial affair in South Africa, especially over the last 60 years. Recent research conducted by government-led and independent agencies shows declining student achievement within an education system that employs 11 home languages for education in the first three grades of primary school, followed by a transition to English medium for the majority (approximately 80%) of speakers of African languages. Research that focuses on the linguistic practices of students in urban settings suggests that there is a disjuncture between the construction of multilingualism within contemporary education policy and the multilingual reality of students (e.g., Heugh, 2003; Makoni, 2003; Makoni & Pennycook, 2012; Plüddemann, 2013; Probyn, 2009; Stroud & Heugh, 2011). There is also a disjunction between constitutional and other government policies that advance, on paper, a multilingual policy, yet are implemented through an assimilatory drive towards English (Alexander & Heugh, 1999). As predicted nearly two decades ago, the ideological framing of multilingualism during the negotiations in the early 1990s was to have consequences for the way in which language policy would unfold in the education sector over the next 20 to 30 years (Heugh, 1995, 1999). While poor student achievement in school may be ascribed to a range of socioeconomic indicators, this article draws attention to contributory factors that relate to language(s) in education. These include different constructions of multilingualism in education in relation to sociolinguistic and educational linguistic considerations, contradictory interpretations of multilingual education in a series of education policy documents, pedagogical weaknesses, and recent attempts to strengthen the provision of African languages education alongside English in the first 10 years of school (Grades R and 0–9; e.g., Department of Basic Education (DBE), 2013a, 2013b).

This article surveys recent English-language research on language policy and education in the 15 countries that are now two decades removed from Soviet hegemony. I examine how researchers employ geometric concepts such as asymmetry, parallelism, and trajectories to analyze multilingualism in this region. I then discuss the spatial turn in post-Soviet scholarship on language policy and schooling through attention to the ways language is produced in and through place, the management and experience of language in particular places, and the production of place through language and schooling. In conclusion, I argue that states have inherited schools with a Soviet-era commitment to multilingualism, but have been challenged to transform them into new types of post-Soviet plurilingual institutions—ones that generally promote the titular language, create space for instruction in minority languages, and educate in a foreign language. Evidence from these countries also speaks powerfully to the ways teachers, students, and parents use school space in dynamic ways to negotiate community boundaries and cultivate particular national identities through deliberate language practice.

This article focuses on the multilingual educational policies in India and Pakistan in the light of challenges in implementation and everyday communicative practices. The challenges these countries face in the context of the contrasting forces of globalization and nationalism are common to those of the other communities in this region. Both India and Pakistan have adopted versions of a tripartite language formula, in which the dominant national language—Urdu in Pakistan, and Hindi in India—along with a regional language and English are to be taught in primary and secondary schools. Such a policy is aimed at accommodating diverse imperatives, such as providing access to schooling to everyone regardless of their mother tongues, developing national identity through competence in a common language, and tapping into transnational economic resources through English. However, this well-intentioned policy has generated other tensions. There are inadequate resources for teaching all three languages in all regions and social levels. Certain dominant languages enjoy more currency and upset the multilingual balance. Furthermore, as people integrate English into their repertoires in recognition of the better-paid employment opportunities and communication media associated with globalization, language practices are becoming more hybrid. To resolve such tensions between policy and practice, some scholars propose a plurilingual model indigenous to the region. Rather than compartmentalizing languages and demanding equal competencies in each of them, such a model would allow for functional competencies in complementary languages for different purposes and social domains, without neglecting mother-tongue maintenance.

Increasing multilingualism in Canada has captured the interest of applied linguists who investigate what it implies for policy and educational practice. This article provides a review of recent discussions of Canadian policy in the literature, current research on multilingual learners, and emerging innovations in multilingual pedagogies. The literature on policy indicates that some researchers treat policy as text and identify disjunctions between policy documents and the reality of a linguistically and culturally diverse population, while others view it as discursive practice and document how policy is constructed locally through language in response to a changing environment. The research on multilingual learners is based primarily on field-based reports that reveal how multilingual language practices are complex, dynamic, and ideological, and are tied to identity construction. The growing number of innovations in multilingual pedagogies suggests that more educators are beginning to see identity work and multimodal literacies as central to teaching students of diverse origins. This article concludes that there is a gap between official language policy and research on multilingualism in Canada.

Since the handover, policymakers in Hong Kong have faced the daunting task of determining the educational roles of two major international languages (Putonghua and English), as well as a vibrant local language (Cantonese), which is the mother tongue of around 90% of the city's predominantly Chinese population. Their response to this unprecedented challenge has been to set the ambitious goal of developing students’ ability to read and write Chinese and English and to speak Cantonese, Putonghua, and English. At the same time, however, they are pursuing policies that in some respects run counter to this commendable if ill-defined aim. This article examines the background to and rationale for the promotion of biliteracy and trilingualism and reviews recent research into the government's major language-in-education initiatives since 1997, namely, the adoption of a compulsory mother-tongue policy at junior secondary level, the recent fine-tuning of this controversial policy, and the use of Putonghua as the medium of instruction in Chinese subjects at primary and secondary levels.
