Reviewed by: Second language acquisition by Roumyana Slabakova Tania Ionin Second language acquisition. By Roumyana Slabakova. Oxford: Oxford University Press, 2016. Pp. xxi, 483. ISBN 9780199687275. $40. Introduction This book is a textbook of second language acquisition (SLA) written within the theoretical framework of the generative approach to SLA research. The intended readers are advanced undergraduate students and graduate students who have some background in linguistics, in particular in syntax and semantics. The text is intended first and foremost for students with a prior background in generative linguistics. While the main linguistic concepts are explained when they are introduced, such explanations are necessarily brief, and students with no prior background in linguistics would find the more technical parts of the text somewhat difficult to follow. However, students or other readers who have a general interest in language and/or language acquisition, but lack a background in generative linguistics, should still be able to follow the main concepts presented in the book. This textbook is quite unique in that, while its focus is on theoretical research on SLA, it explicitly makes the link to potential pedagogical relevance of the research findings. Brief summary The book consists of thirteen chapters, divided into three parts. Each chapter ends with a section of exercises; at the end of the book are a glossary, references, and an index. Part I, ‘Language’, provides a brief overview of the relevant background information that readers need to have in order to fully appreciate the rest of the book. Ch. 1, ‘Language architecture’, lays out the central argument of generative linguistics for the innateness of language and introduces the reader to several famous proposals on the structure of the language faculty. Ch. 1 then addresses the task faced by a second language learner and lays out the logic of the methodology used in generative SLA research. Ch. 2, ‘Language variation’, walks the reader through the history of the generative study of language variation, from principles and parameters through the minimalist program. Like Ch. 1, Ch. 2 ends by considering the implications of the theoretical linguistic research for the learning task of a second language learner. The goal of Ch. 3, ‘The psychological reality of language in use’, is to prepare the reader for later chapters that address second language processing by reviewing the central models and findings of the literature on language processing and psycholinguistics more generally. Part II, ‘Language acquisition’, has the goal of placing the study of SLA into the study of language acquisition as a whole by considering a number of different language-acquisition scenarios. The focus of this part is on the respective contributions of age of acquisition and of input quantity and quality to the task of language acquisition. Ch. 4, ‘The critical period hypothesis’, goes over the history of critical period studies and addresses the debate about the existence of critical or sensitive periods in SLA. This chapter also considers the role of input, bringing together a number of quite distinct phenomena, including variable input, comparisons between heritage speakers and second language learners, and variability among native speakers at different educational levels. Ch. 5, ‘First language acquisition, two first languages’, provides an overview of the process of first language acquisition; most of the chapter is devoted to monolingual first language acquisition, but the last section discusses simultaneous bilinguals, who form a natural link between monolinguals and adult second language learners. In Ch. 6, ‘Child second language, multilingual and heritage language acquisition, language attrition’, a variety of other types of language acquisition scenarios are discussed. Throughout this chapter, and especially in the last section, the focus is, once again, on the relative contributions of age of acquisition and input quantity and quality to the outcome of the language acquisition process. The position taken in this chapter, and [End Page e198] throughout the rest of the book, is that the effects of age can potentially be overridden by rich input, and that universal grammar remains active in SLA by adults. Part III, ‘Second language acquisition’, is the heart of the book. In addition to providing an overview of SLA research in the core areas of linguistics (with the one exception of...

This article discusses sociolinguistically oriented research on second language acquisition (SLA) in the decade since Firth and Wagner (1997). Over the last 10 years, substantial progress has been made in developing a model of the sociolinguistic processes that inform second language acquisition. This model is supported by empirical evidence on the relationship between social context and second language use and acquisition, which shows that learners' second language (L2) input and processing of L2 input in social settings are socially mediated, that social and linguistic context affect linguistic use, choice, and development, and that learners intentionally assert social identities through their L2 in communicating in social contexts. A strength of sociolinguistically oriented SLA research is its strong focus on linguistic outcomes, tracking the impact of contextual factors in producing those outcomes. Preston (2000, 2002) and Fasold and Preston (2006) provided a central sociolinguistic framework to integrate research on the interaction of social factors and cognitive processes in producing interlanguage, which is a variable linguistic system.

Instructed second language acquisition (ISLA) is a subfield of second language acquisition (SLA) that investigates any type of second language (L2) learning or acquisition that occurs as a result of the manipulation of the L2 learning context or processes. Learners' self‐study of the target language is also considered part of ISLA; however, ISLA research has generally focused more on traditional, face‐to‐face classrooms, as well as online instruction. The defining feature of L2 instruction is that there is an attempt, either by teachers or instructional materials, to guide, facilitate, and manipulate the process of L2 acquisition.

The field of second language acquisition (SLA), a relatively new field of academic study, traces its roots only to the second half of the last century. The field of SLA has roots in various disciplines and areas of study, including the fields of child first language (L1) acquisition, linguistics, psychology, and language pedagogy. Thus, SLA has moved well beyond a one-sided focus on learner internal mechanisms, be they linguistic or cognitive. A great deal of SLA research has concentrated on differences between L1 and second language (L2) acquisition in terms of ultimate attainment. Some SLA researchers argue that learning is based on experience of language usage. More recent SLA research conducted within a cognitivist approach has been designed to provide online measures of processing and interpretation of the L2 and has thus shifted somewhat away from the analysis of naturalistic corpora.

Research shows many problems and ambiguities of second language acquisition (SLA), which have made learners and readers worldwide unsatisfied. Therefore, this study attempts to highlight theories and research that have comprehensive explanations of the problems and ambiguities of second language acquisition, which learners of English as a Foreign Language (EFL) face while learning a second or foreign language. After that, the study discusses a framework discussion on second language acquisition (SLA). It discusses the historical background of SLA research on different decades and the most notable views of different scholars throughout the past decades on second language acquisition. This study is a longitudinal research that identifies the advantages that could be an assist to English as Foreign Language (EFL) learners. Longitudinal research is always based on the qualitative method. This study's data is based on the qualitative method that collects views, opinions, materials, and earlier studies on second language acquisition (SLA). It reveals the most significant theories which precisely connected to second language acquisition (SLA) and largely to applied linguistics. The study resulted in that: (i) second language acquisition still has several doubts and ambiguities in its many different aspects, (ii). In this study, the researcher summarizes second language acquisition (SLA) research's main goals and draws comparisons on the scholars' dissimilarities between language learning and second language acquisition (SLA) on different perceptions that could give insights towards learning of second and foreign languages easily by the English as Foreign Language (EFL) learners.

Artificial Intelligence (AI) has emerged as a central driver of innovation in English Language Teaching (ELT), yet despite widespread adoption of AI-enabled tools, the field of research remains scattered and under-theorized. This systematic review synthesizes peer-reviewed literature published between 2015 and 2025 to identify the state of current research and reveal the key gaps that continue to limit knowledge development. Guided by PRISMA principles, 112 studies were initially retrieved from Scopus, Web of Science, ERIC, and Google Scholar. Following a rigorous inclusion and exclusion process, 48 studies were analyzed using thematic synthesis. The review identifies six major gaps in existing research: the lack of pedagogical integration of AI tools with established second language acquisition (SLA) frameworks, the overconcentration of research in technologically advanced nations with limited evidence from Global South contexts, the neglect of cognitive and affective variables such as cognitive load, motivation, and learner anxiety, the scarcity of longitudinal and experimental research designs, the insufficient focus on equity and accessibility in diverse learning environments, and the absence of robust investigations into ethical challenges such as plagiarism, data privacy, and algorithmic bias. The results indicate that although AI holds great promise for revolutionizing second language acquisition, the current body of research falls short in offering thorough or fair insights. The article ends with a research agenda for the future that prioritizes theory-driven, longitudinal, and contextually inclusive methods, especially in high-stakes test preparation contexts like India’s IELTS.

Towell Liang Chen The lexicon-syntax interface in second language acquisition. Ed. by Roeland van Hout, Aafke Hulk, Folkert Kuiken, and Richard J. Towell. (Language acquisition and language disorders 30.) Amsterdam: John Benjamins, 2003. Pp. vi, 232. ISBN 158811418X. $119 (Hb). This volume contains ten papers, including introductory and concluding chapters by the editors. These papers were presented at ‘The interface between syntax and the lexicon in second language acquisition’ seminar organized by the editors and held in Amsterdam in 2001. Richard Towell (1–20) first outlines the linguistic and psychological perspectives of second language acquisition (SLA) as a context against which the eight papers are then briefly introduced and evaluated. The complementary nature of such different perspectives of SLA research is highlighted. Roger Hawkins and Sara Liszka (21–44) attribute errors in tense marking made by Chinese speakers of English in their spontaneous oral production (e.g. The police CAUGHT the man and TAKE him away.) to the difficulty in assigning the formal feature [past] to the category T(ense), as such a feature is not selected in their first language (L1). Norbert Corver (45–68) analyzes second language (L2) expressions produced by Turkish L2 learners of Dutch within a minimalist interface perspective and argues that ‘L2-expressions are perfect grammatical objects, where perfection amounts to legibility of its information to the systems with which it interacts’ (66). Ineke van de Craats (69–96) uses longitudinal data of eight adults with Turkish and Moroccan Arabic L1 backgrounds learning Dutch as an L2 to explore how the grammatical knowledge of an L2 learner is encoded in the lexicon. It is argued that while these L2 learners are more aware of crosslinguistic differences in morphological and lexical properties of words, they originally assume the L1 formal feature constellation, which gradually changes in favor of the L2 ones. Nigel Duffield (97–128) proposes a dual model of competence to account for both the categorical aspects and the various types of lexical and syntactic gradient effects of our implicit grammatical knowledge. Ton Dijkstra (129–50) reviews available literature on the lexical storage and retrieval in bilinguals, which suggests (i) a largely automatic bilingual word identification system, (ii) the slower activation of L2 than L1, depending on relative L1/L2 proficiency, and (iii) the potential influence of experimental and contextual factors on patterns observed in experiments. John N. Williams (151–74) focuses on the similarities and differences between human and connectionist learning of noun classes. In particular, it is argued that while an arbitrary noun class system with masculine and feminine genders is learnable both by humans and by connectionist networks (via distributional information), gender is a persistent problem in SLA as well as in connectionist learning. Laura Sabourin and Marco Haverkort (175–96) show that differences in linguistic processing are quantitative between aphasic speakers and normative speakers, but are qualitative between native speakers and second language learners. David W. Green (197–218) reviews current research on the representation and processing of lexicon and grammar in L2 and claims that they ‘marginally favor the convergence hypothesis’, that is, ‘as proficiency in L2 increases, the networks mediating L2 converge with those mediating language use in native speakers of that language’ (212), rather than the differential representation hypothesis (i.e. an L2 learner’s representation and processing of the lexical and grammatical knowledge of the target language differ from that of a native speaker of that language). Roeland van Hout, Aafke Hulk, and Folkert Kuiken (219–26) highlight the lexicon as the driving force of language acquisition in their concluding remarks. They suggest that varieties in methodology, learners and languages, linguistic domains, contexts and tasks, and perspectives all need to be considered in order to address more fully the issues in second language acquisition examined in this volume and beyond. This work represents the latest developments in the generative/psycholinguistic studies of second language acquisition. It will certainly advance our understanding of this important...

The rapid integration of artificial intelligence (AI) into language education has transformed traditional second language acquisition (SLA) practices. This study investigates the impact of AI-powered language learning tools (e.g., ChatGPT, Duolingo, and Grammarly) on learners' linguistic competence, motivation, and autonomy. Using a mixed-methods approach, data were collected from 120 intermediate English learners across diverse linguistic backgrounds. Quantitative data were gathered through pre- and post-tests assessing grammar, vocabulary, and writing skills, while qualitative data were obtained through semi-structured interviews and learner diaries. Results indicate significant improvements in vocabulary acquisition and writing accuracy among participants using AI tools, alongside enhanced motivation and self-directed learning. However, challenges such as over-reliance on AI and limited conversational practice were also identified. The findings contribute to the growing body of research on technology-enhanced language learning and offer practical implications for educators and developers of AI-driven language tools.

Professionals are implementing artificial intelligence (AI) technology in different fields owing to its diverse uses and benefits. Similarly, AI professionals are also beginning to implement AI technology in foreign-language education and second-language learning. Therefore, through a systematic literature review, this paper analyzes the role of AI in helping learners of a second language to master pronunciation. A detailed and in-depth search of different well-known databases was conducted, and of 116 articles, only 39 were selected for this paper. AI algorithms can advance language learning and acquisition in almost every dialect and could be significant for different parties in different ways. For example, organizations could utilize AI technology to develop their workers’ knowledge; individual learners could use AI technology to facilitate their studies anywhere and anytime; and traditional learning institutions could incorporate AI-powered methods of language learning to diversify learners’ opportunities. There are many benefits to employing AI in language learning, particularly in second-language learning.

Better understanding of the varied factors that account for successful second language acquisition is a goal that is of obvious interest to anyone within the field of language study. Before the influence of these factors can be adequately understood, of course, they must be defined and utilized in an accurate and consistent way. This paper endeavors to explore and clarify the ambiguity surrounding usage of the terms intelligence and aptitude in second language acquisition in effort to understand the more central issue of how the qualities designated by these terms relate to second language acquisition. This should enable a clearer picture to emerge about the relative importance of intelligence and aptitude among the constellation of factors associated with second language acquisition.

How does a person learn a second language? In this provocative book, Marysia Johnson proposes a new model of second language acquisition (SLA)—a model that shifts the focus from language competence (the ability to pass a language exam) to language performance (using language competently in real-life contexts). Johnson argues that current SLA theory and research is heavily biased in the direction of the cognitive and experimental scientific tradition. She shows that most models of SLA are linear in nature and subscribe to the conduit metaphor of knowledge transfer: the speaker encodes a message, the hearer decodes the sent message. Such models establish a strict demarcation between learners’ mental and social processes. Yet the origin of second language acquisition is located not exclusively in the learner’s mind but also in a dialogical interaction conducted in a variety of sociocultural and institutional settings, says the author. Drawing on Vygotsky’s sociocultural theory and Bakhtin’s literary theory, she constructs an alternative framework for second language theory, research, teaching, and testing. This approach directs attention toward the investigation of dynamic and dialectical relationships between the interpersonal (social) plane and the intrapersonal (individual) plane. Johnson’s model shifts the focus of SLA away from a narrow emphasis on language competence toward a broader view that encompasses the interaction between language competence and performance. Original and controversial, A Philosophy of Second Language Acquisition offers: · an introduction to Vygotsky’s sociocultural theory and Bakhtin’s literary theory, both of which support an alternative framework for second language acquisition; · an examination of the existing cognitive bias in SLA theory and research; · a radically new model of second language acquisition.

Several studies have been conducted to try and understand and explain the morphological and syntactic aspects of adult second language acquisition (SLA). Two prominent hypotheses that have been put forward concerning late L2 speakers' knowledge of inflectional morphology and of related functional categories and their feature values are the Impaired Representation Hypothesis (IRH) and the Missing Surface Inflection Hypothesis (MSIH). The cross-linguistic comparison of the acquisition of questions in German and French provided in this study offers a new perspective to differences and similarities between first language acquisition (FLA) and adult SLA. Comparing a Germanic and a Romance L2, differing not only in their overall linguistic properties (such as i. e. OV/VO, V2, clitics), but explicitly in the formation and regularities of questions, we present striking similarities in adult SLA, and irrespective of the first and the second languages and of instructed versus non-instructed learning. The investigation of the adult SLA of morphological and structural aspects of questions in French and German strengthens the assumption that the acquisition of morphology and syntax is connected in French and German FLA but is disentangled in adult SLA. Our data reveal variability of question syntax, and with the syntactic position of the verb in particular. Instead of discovering the correct position of the verb at a certain stage of acquisition which can be accounted for by parameter setting in FLA, the adult learners gradually approach the target word order but still exhibit a great deal of variation after several years of exposure to the L2. The findings provided here contradict the predictions of the MSIH (Prévost/White 2000; Ionin/Wexler 2002; among others), for not only morphological features, but syntactic finiteness of finiteness are problematic in adult SLA, and that the Impairment Representation Hypothesis (IRH) (Beck 1998; Eubank 1993/1994; among others) accounts for these differences in first and second language acquisition. IRH and FDH mirror our findings, by predicting the use of (domain-general) strategies instead of agreement or feature checking mechanisms.
