Background. Digital technologies have long become an integral part of everyday life. Internet and Social Networking Sites (SNS) are considered to be one of the socialization institutions along with traditional school and family.

Objective. The research is concerned with studying the peculiarities of teenagers’ social psychological well-being when using SNS. The analysis aims at revealing the impact of demographic, social stratifying and social psychological factors on the type of adolescent self-performance at SNS, their attitude towards regulations of interaction at SNS, their concern about potential risks and also opinions about the effects of SNS socialization on their personality.

Design. The paper is based on the results of 2074 school-aged adolescent survey conducted in 2016 in Moscow region, Russia.

Results. According to the survey, the adolescent well-being when using SNS depends on the type of their self-presentation. The data showed that affective significance of social networking for adolescents who seek the attention of the strangers produces a negative impact on their emotional well-being: those who refer to their SNS profile as “provocative” are more likely to feel the “addiction to virtual interaction and other’s opinions” – 17.4% (mean 7.1%; p≤ .0004), being disturbed by “more popular profiles” – 21,7% (mean 4.2%; p≤ .00001).

Conclusion. The survey showed that nowadays adolescents deem the SNS as the most important communicative field where the fundamental age-related changes take plaare foundce. The tendency to expand social contacts by means of virtual communication was found to produce negative impact on adolescent personal development and social interaction in real life.

The paper is devoted to the dynamics of pithy features of student attitude to the political leaders over the past 10 years in Moscow, Russia. The research data in 2004 and 2014 are based on the method of semantic differential. The research involved the high school students of 10-11 grades, Moscow, Russia (80 individuals in 2004 and 110 individuals in 2014). The students got a list of political leaders, each of them they need to evaluate by a number of semantic features (scales). In both research the same set of 33 words describing various personality traits was used. In 2004 the list of political leaders was composed of the Soviet state’s leaders and the most popular political leaders of that time. In 2014 research, the list of politicians was partially preserved and supplemented because of the changed political situation in Russia. Also the 2014 list was extended with several foreign politicians’ names. The hypothesis of the study suggests that the generation of 2014, compared with the high school students of 2004 presupposes a more simple perception structure of the political leaders.

According to the results of the comparative analysis of the factors the following conclusions were made: 1) simplification of psychosemantic structure which was indicated by the decreased number of factors from 5 in 2004 to 4 in 2004, 2) in 2014 students there is no negative moral evaluation of intolerant manifestations of personality, 3) increased importance of moral characteristics in evaluating the activity and self-presentation of a political leader, 4) the value of power and intelligent characteristic increased.

The paper presented texts of the three previously unknown Lvygotsky’s journal notes and comments on them. These texts were published in mid-July and early September 1917 in the Jewish weekly «New Path» under the pseudonym «L.S.» and «W». In these texts, Lev Vygotsky describes the features of the political behaviour of the Jewish population in connection with the revolutionary events in Russia. On the one hand, a clear discrepancy between the activation of party work and political rhetoric is mentioned, and on the other hand, reduction of the significance of Jewish communal life is highlighted. As a key characteristic of social and psychological wellbeing of the Jewish population Vygotsky singles out absenteeism, i.e. the lack of interest in politics. Eventually the scientist captures the increase in uncertainty in the Jewish environment and fear of the future political, social and economic reforms in Russia. In the comments on Vygotsky notes, there are definitions relating to the various features of the activities of the Jewish political parties and public organizations, information about various policy documents and staff characterized by social and political situation before the elections in the Consituent Assembly (Uchreditel’noe Sobranie). Particular attention is paid to the analysis of stylistic and structural features of the commented text construction. By implicit quoting the relationship between Vygotsky’s texts and the works of other authors is identified.

Particular attention is paid to the author’s attitude to religious texts, which allows to select a characteristic feature of the «double vision» of real events of the revolution against the background of the Jewish history. The comments help to single out features of the political identity of the young Lev Vygotsky in the period between the two revolutions, which is important to study his biography and understanding of his world view.
