 Human development involves different stages appropriate to each particular age. It is known that physical and mental growth of a person is closely related to his/her age. To properly manage the learning and upbringing processes, teachers have made many attempts to classify periods of human life and knowledge, which carries important information. Each age period corresponds to the appropriate level of physical, cognitive, social and emotional development. Therefore, the theory of human development elaborated by Erik Erikson with regard to adolescence builds awareness that this age group develops due to the physical, biological, cognitive, social, and emotional factors that influence the individuals personality.

The theory of human development of Erik Erikson plays a crucial role in social psychology. Here, the author aims to explain the growth of personality in the context of the social environment. Erikson argues each stage of development has inherent expectations of society, which the individual can either justify or not, and then he/she is either included in society or rejected by it (McLeod, 2017). Hence, this idea has formed the basis for distinguishing the stages of life. As such, each stage is characterized by the roles a person plays in the community. However, the solution of the problem depends both on the already achieved level of human development and on the general spiritual atmosphere of the society in which this individual lives.

The theory identifies the fifth stage of human development as adolescence, which lasts from 12 to 19 years of age. It postulates that the transition from childhood to adulthood causes both physiological and psychological changes (McLeod, 2017). Thus, the latter are manifested as an internal struggle between the aspiration for independence, on the one hand, and the desire to remain dependent on those who care about a person as well as wish to be free from the responsibility for being an adult, on the other hand. As a result, parents or other close people become enemies or idols. Hence, a teenager is constantly confronted with questions: Who is he/she and who will he/she be in the future? Is he/she a child or an adult? How does his/her ethnicity, race and religion affect attitudes of the public towards him/her? Therefore, this theory helps develop social responsibility and sexual maturity.


Human development of schoolchildren relates to the educational activity, during which the child does not only master skills and methods of acquiring knowledge, but also is enriched with new meanings, motives and needs. Moreover, adolescence is one of the most difficult periods of school ontogeny, which is called transitional, since it is characterized by a transition from childhood to adolescence, from immaturity to maturity (Bhabha, 2014). Adolescence is a period of rapid and uneven growth of the body. In this regard, inconsistency, uneven development of the heart and vessels, as well as heightened activity of endocrine glands often lead to some temporary circulatory disorders, increased blood pressure, cardiac tension in adolescents, and the rise in their excitability, which can be expressed by irritability, fatigue, dizziness and palpitation. In addition, the nervous system of the youngster is not always able to withstand strong or long-acting stimuli, and under such influence it often passes into a state of inhibition or conversely strong excitation.

Cognitive and Language Development of Adolescents

The development of the intellectual sphere of teenagers is accompanied by numerous changes that distinguish them from young children. According to the research, the cognitive development is marked by their ability to think abstractly (McLeod, 2017). Besides, during adolescence one finds new motivation in studying connected with advanced ideals, professional intentions and future achievements. Therefore, an adolescent starts to develop theoretical thinking that allows him/her to shape reasoning, which goes from general to particular. For example, a teenager is able to solve intellectual problems operating with different hypotheses due to his/her new ability (Capuzzi & Stauffer, 2016). Furthermore, a juvenile acquires the adult logic of thinking that allows him to analyze events that occur in everyday life.

In adolescence, children considerably enrich their language. Thus, they expand their dictionary and can operate with a bigger number of words. In fact, they discover that a language helps them express their thoughts and fix a certain view of the world (Capuzzi & Stauffer, 2016). For instance, a teenager begins to use easily non-standard forms of the language. In addition, adolescents often imitate adult speech, follow instances from media, television, their peers, etc. In this period, youngsters acquire slang that brings a special meaning to their subculture. Hence, this allows them to escape from social control. However, cognitive development of the teenagers personality is quite contradictory. During this time, children are more likely to communicate with their peers, interpersonal contacts are formed, and adolescents have a greater desire to belong to a certain group.

Physical Development in Adolescence

The central factor of physical development in adolescence is puberty, which has a significant effe
