AbstractThe human brain has been uniquely equipped with the remarkable ability to acquire more than one language, as in bilingual individuals. Previous neuroimaging studies have indicated that learning a second language (L2) induced neuroplasticity at the macrostructural level. In this study, using the quantitative MRI (qMRI) combined with functional MRI (fMRI) techniques, we quantified the microstructural properties and tested whether second language learning modulates the microstructure in the bilingual brain. We found significant microstructural variations related to age of acquisition of second language in the left inferior frontal region and the left fusiform gyrus that are crucial for resolving lexical competition of bilinguals’ two languages. Early second language acquisition contributes to enhance cortical development at the microstructural level.Significant statementThe ability to communicate in two languages is becoming more and more important in the increasingly global community. Does learning a second language (L2) affect the human brain development? At the macrostructural level, there has been neuroimaging evidence revealing neuroplasticity induced by the acquisition of L2. Here, we employed the quantitative MRI technique to investigate the microstructural variations related to L2 learning, and found that age of acquisition of L2, but not its proficiency, is associated with cortical proliferation. Early second language acquisition seems to enhance cortical development at the microstructural level.

AbstractThe increasing recognition of the concept language ideology and the corresponding increasing use of the term have not yet been matched by applications in the field of second language acquisition. However, applications of the concept in analysis of actual classroom practices have shown it to have considerable explanatory power. Greater consideration of language ideology in SLA is necessary not only to achieve greater understanding of the role of ideology in various areas but also to show connections between these areas that may yield important generalizations and to impel the application of the concept in areas where it has been neglected by highlighting its uneven treatment.

<p>The importance of the learner's attitudes and motivation plays a major role for most psycholinguists, either in a language learning situation or in a second language acquisition context. A quick look at the major theories of language acquisition can be helpful to establish this. Krashen's monitor model argues attitudes and motivation most influential in unconscious language acquisition. The learner's motivational level acts as an affective filter on language intake (Krashen 1981, p. 102). In another model language learning begins when the learner feels motivated to communicate something to someone (see Carroll's conscious reinforcement model, 1981). Reinforcement takes place when the desired end is obtained. Bialystok's strategy model (1978) demonstrates that it can be assumed that learners will seek language exposure only if they feel motivated. Therefore, using their explicit and/or implicit knowledge, communication will take place. This study investigates the challenges and the importance of motivation for second language learning or SL acquisition.</p>

In China, the second language learning has always played an important role in primary and higher education. The issue of how children acquire the second language has experienced a boom in China over the past decade as the proficiency of a person’s English level mainly depends on its acquisition in primary stage. The main focus of this paper is to examine the role of UG in the second language acquisition and to what extent it plays in the process. To illustrate this, the four access hypotheses were given firstly. In addition, the role of UG from the aspect of Chinese learners’ acquiring the English reflexives was discussed. In this section, the importance of analyzing the reflexives and the different features of them in Chinese and English were exhibited.

Learning Language

Usage-based approaches focus on learning language through engaging in the interpersonal communicative and cognitive processes. They consider language as the best accomplishment of our social and cognitive competences which bridges society and cognition. Based on usage-based approaches, language can be learned from language use, by means of social skills and generalizations over usage events in interaction. These approaches actually explore how language learning occurs through language experience. Therefore, usage-based approaches are input-dependent and experience-driven and assume frequency of usage as an inseparable part of language learning which plays an important role in the language production, language comprehension, and also grammaticality of the patterns. While usage-based approaches have been successful in showing how first language is learnt from the input, it is still less clear how these approaches can be made use of in second language learning. The present study provides an overview of the usage-based approaches to second language acquisition and their cognitive and social underpinnings. Firstly, the notion, underlying tenets, and major constructs of usage-based approaches are summarized. Then usage-based linguistics is described in detail. Finally, cognitive and social aspects of usage-based approaches are taken into account.

Learning Success

Every case of second language learning is different, but they are often influenced by systematic factors. What causes a learner to succeed or fail? In this case study, the language learning experiences of a single nonnative English speaker who successfully acquired English sheds light on the interplay between several of these aspects. An interview with a single adult subject reveals that for this particular individual, a high aptitude, as well as identity and personality characteristics that aligned with an openness to experience and learning in general, were more effective than factors of motivation. While identifying how and why a single individual may be successful or unsuccessful might not be generalizable to all learners, it can serve as a tool in helping to understand differences in L2 learning success.

Is there a critical period for second language acquisition? When should one begin learning a second language? These are questions that have always been present and they stiil have not become any less controversial or complex. There is not any specific age that could be determined or proclaimed to be the most appropriate. A lot of things must be taken into consideration with spesific emphasis on the goals of the learner. Whether reaching a native -like accent and proficency is the ultimate aim or obtaining a certain level that will enable an everyday communication? Since a great number of experiments and research have shown that both younger and older students can achieve high levels in their second language, a fair atribute and attention should be paid to both theories respectfully.It has been hypothesized that there is a critical period for second language acquisition as well as for first language acquisition. According to this theory there is a time in human development when the brain is predisposed for success in language learning. It is belived that some developmental changes in the brain affect the nature of language acquisition. Therefore, any language learning that occurs after the end of the critical period may not be based on innate biological structures belived to contribute to first language acquisition or second language acquisition in early childhood. The general learning abilites that the older learners depend on, are claimed to be less efective than the innate capacities available to young children. Most studies of the relationship between age of acquisition and second language development have focused on learners’pronounciation. It is frequently observed that most children from immigrant families eventually speak the language of their new community with native –like fluency and accent, while their parents quite often fall behind in this mastery even long after they had been living and working in the new community. Nevertheless, some researches argue that older learners may have one advantage: they appear to be able to learn faster in the early stages of second language learning. Age is one of the characteristics that determine the way in which an individual approaches second language learning. But the opportunities for learning (inside the classroom and outside), the motivation to learn , and individual differences in aptitude for language learning are also important determining factors that affect both rate of learning and eventual susscess in learning. It must be acknowledged that achieving native-like mastery of the second language is neither a realistic nor a neccessarilya desired goal for many second language learners in many educational contexts.
