Second Language Acquisition and the Critical Period Hypothesis is the only book on the market to provide a diverse collection of perspectives, from experienced researchers, on the role of the Critical Period Hypothesis in second language acquisition. It is widely believed that age effects in both first and second language acquisition are developmental in nature, with native levels of attainment in both to be though possible only if learning began before the closure of a "window of opportunity" – a critical or sensitive period. These seven chapters explore this idea at length, with each contribution acting as an authoritative look at various domains of inquiry in second language acquisition, including syntax, morphology, phonetics/phonology, Universal Grammar, and neurofunctional factors. By presenting readers with an evenly-balanced take on the topic with viewpoints both for and against the Critical Period Hypothesis, this book is the ideal guide to understanding this critical body of research in SLA, for students and researchers in Applied Linguistics and Second Language Acquisition.

This text provides a diverse collection of perspectives, from experienced researchers, on the role of the critical period hypothesis in second language acquisition.

Biolinguistics involves the study of language from a broad perspective that embraces natural sciences, helping us better to understand the fundamentals of the faculty of language. This Handbook offers the most comprehensive state-of-the-field survey of the subject available. A team of prominent scholars working in a variety of disciplines is brought together to examine language development, language evolution and neuroscience, as well as providing overviews of the conceptual landscape of the field. The Handbook includes work at the forefront of contemporary research devoted to the evidence for a language instinct, the critical period hypothesis, grammatical maturation, bilingualism, the relation between mind and brain and the role of natural selection in language evolution. It will be welcomed by graduate students and researchers in a wide range of disciplines, including linguistics, evolutionary biology and cognitive science.

The past fifteen years have witnessed an increasing interest in the cognitive study of the bilingual. A major reason why psychologists, psycholinguists, applied linguists, neuropsychologists, and educators have pursued this topic at an accelerating pace presumably is the acknowledgment by increasingly large numbers of language researchers that the incidence of monolingualism in individual language users may be lower than that of bilingualism. This alleged numerical imbalance between monolinguals and bilinguals may be expected to become larger due to increasing international travel through, for instance, tourism and trade, to the growing use of international communication networks, and to the fact that in some parts of the world (i.e., Europe), the borders between countries are effectively disappearing. In addition to the growing awareness that bilinguals are very common and may even outnumber monolinguals, there is the dawning understanding that the bilingual mind is not simply the sum of the cognitive processes associated with each of the two monolingual modes, and that the two languages of bilingual may interact with one another in complicated ways. To gain a genuinely universal account of human cognition will therefore require a detailed understanding of language use by both pure monolinguals as well as bilinguals, unbalanced and balanced, and of the representations and processes involved. These two insights, that bilingualism is a common human condition and that it may influence cognition, were presumably instrumental in putting bilingualism on the agendas of many researchers of cognition and language in recent years. But other reasons may have played a role too: The study of bilingualism also provides a unique opportunity to study the relation between language and thought. A final reason for the growing interest in this area of research is the awareness that bilingualism may confer the benefit of broadening one's scope beyond the limits of one's own country and culture. This book serves as an excellent introduction to the important topics in the psycholinguistic study of bilingualism. The chapters represent a comprehensive and interrelated set of topics that form the core of contemporary research on the psycholinguistics of bilingualism. The issues raised within this perspective not only increase our understanding of the nature of language and thought in bilinguals but also of the basic nature of the mental architecture that supports the ability to use more than one language.

This book takes a hard look at some of the assumptions that are customarily made concerning the role of age in second language acquisition. The evidence and arguments the contributors present run counter to the notion that an early start in second language learning is of itself either absolutely sufficient or necessary for the attainment of native-like mastery of a second language. Another theme of the book is a doubt that there is a particular stage of maturity beyond which language learning is no longer fully possible. In short, the book presents a challenge to those who take it as given that second language learning is inevitably different in its essential nature from language acquisition in the childhood years and that second language knowledge acquired beyond the critical period is in all circumstances and in all respects doomed to fossilize at a non-native-like level.

Seminar paper from the year 2002 in the subject English Language and Literature Studies - Linguistics, grade: 1,3, Ruhr-University of Bochum, 9 entries in the bibliography, language: English, abstract: In 1967 Eric Heinz Lenneberg established his groundbreaking work "Biological Foundations of Language" in which he tries to push the biological view on language forward. One important point that is discussed is "language in the context of growth and maturation". The Critical Period Hypothesis (CPH) is the essence of this considerations. Lenneberg tries to find evidence for his theory in the study of retarded, aphasic or deaf children and in neurological studies. But at this time the most striking proof for the CPH, Genie, was still imprisoned in a small room in her parents home. Three years after Lenneberg published his work on the CPH, 131/2 years-old Genie was recovered by an eligibility worker and her case rapidly aroused the interest of neurologists, psychologists and linguists. Susan Curtiss, a graduate student of the UCLA Linguistic Department got the possibility to work with Genie for the years to come. Her work Genie - A Psycholinguistic Study of a Modern-Day ′Wild Child′ compiles her experiences on working with Genie added by a detailed case history. What Susan Curtiss found out about Genie′s linguistic development seems to be the evidence for the existence of a critical phase for first language acquisition. This paper gives a brief definition of Lenneberg′s Critical Period Hypothesis, summarizes the case history and the data of Genie′s linguistic development and, according to Susan Curtiss, relates Genie′s case directly to the CPH. Over and above that, it tries to explain, why Genie developed a certain amount of language and with this proved the ′strong′ version of Lenneberg′s hypothesis as wrong.

The authors examine the evidence relative to the idea that there is an age factor in first & second language acquisition & goes on to explore the various explanations that have been advanced to account for such evidence. Finally, it looks at educational ramifications of the age question.
