Second language acquisition (SLA) is quite a complex area by definition, considering the variety of the techniques, approaches, and methodologies it can utilize. An essential nuance is that many consider this activity monodisciplinary, albeit multidimensional, apparently because of the specificity and clarity of its purposes. In fact, however, SLA appeals to several disciplines and incorporates knowledge from a range of fields, which makes it even more sophisticated.
First, mastering a language, similar to any education, is intertwined closely with psychology as well as neurophysiology. In particular, it relies on memory studies as the resource to explain the neural and chemical processes that occur in the human brain during learning. Awareness of them, in turn, helps organize the studies in the most effective and secure way. Another group of resources involves articles and reports on age psychology; it is essential to consider the age-related peculiarities of the student when counting the optimal load on him or her. In case of inappropriate calculations, the outcomes may vary from poor academic performance to burnout.
Second, it is noteworthy that a language is not solely a communication tool; it reflects the mentality of the nation that has created it. This calls naturally for social, political, historical, and cultural discourses to become acquainted with the peculiarities of the community. Without this, learning becomes practically senseless, as memorizing words or grammar constructions with no view of their origin and role allows for hardly any associations and anchors that enable their spontaneous use. Among the possible types of resources are surveys, interviews, observations, comparative studies, and other than can depict the community from various angles.
To summarize, second language acquisition is a multidisciplinary area of knowledge, notwithstanding its seeming narrowness. Specifically, to be successful and safe, the learning process should consider the neurophysiology of the brain and rely on it. In addition, it is essential to remember than a language is not an abstract theory, but a product of a certain society. Its formation and performance, in turn, are the subjects of sociology, history, political science, and cultural studies.
