Background. The influence of mild traumatic brain injury (MTBI) on mental functions is not given a proper account in modern neurology and neuropsychology. The data published provide information on the state of higher mental functions (HMF) and on disturbances of the psychological well-being of children and adolescents after MTBI. The analysis of research materials in this area provides data on disorders associated with both local and cerebral symptoms, which form a diverse picture of cognitive and behavioural disorders.

The Objective is to study HMF in adolescents of 10-14 years old after TBI of mild severity as part of the methodology of neuropsychological syndrome analysis (Luria, 1973). Design. The study is based on the original set of techniques designed by A.R. Luria. We focused on assessing the status of various HMF components (motor areas, gnostic areas of memory and intelligence). We also studied the mental activity in its regulatory and dynamic aspects. The population included 31 patients with MTBI and 20 healthy subjects.

Results. The analysis of the results showed that violations of HMF in the acute period were represented by three types of syndromes. The leading place in each syndrome is occupied by deficiency symptoms of non-specific brain structures.

Conclusion. The information obtained enriches the knowledge of neuropsychology about the patterns of development of brain systems and related mental functions in adolescence, and also allows one to choose more suitable options for rehabilitation effects aimed at improving the adaptation of patients, enhancing their quality of life, and preventing negative consequences of MTBI.

The Background of the study is determined by the importance of information exchange for adolescent moral development, in particular the role of cognitive processing of social information (CPI) for the development of moral consciousness.

The Objective of the study was to investigate the relationship between the level of moral development of adolescents and the Internet CPI. The Hypothesis of the study: the features of moral sensitivity and the level of development of moral judgments in adolescents provide background to different stages of cognitive processing of social information on the Internet.

Methods and sampling. The study used the following methods: «Justice – Care» method (S.V. Molchanov) aimed at identifying the level of development of moral judgments was used; the author’s method of identifying the level of moral sensitivity, the method of cognitive processes of assessing social information on the Internet; Yanoff-Bulman scale of basic beliefs (modified By M. A. Padun and A.V. Kotelnikova). The study involved 208 adolescents aged 13-18 years (48% males and 52% females).

Results. On the basis of the cluster analysis, two groups of adolescents were identified – individuals with a high level of development of moral judgments and high moral sensitivity and individuals with a low level of development of moral judgments and heterogeneous moral sensitivity. Moral sensitivity determines how much the subject is aware of the moral content of problem situations. Adolescents with a high level of moral development are characterized by a strong belief in the justice of the world and the experience of the value and significance of their own Self. Differences in cognitive processing of social information are revealed. Adolescents with a high level of moral development are more focused on the choice of response behaviour, taking into account its possible consequences and assessing self-efficacy in the process of social interaction in the Internet space. Adolescents with a low level of moral development are more focused on the interpretive stage of social information analysis, where the task is to understand the moral content of the situation and highlight the moral conflict.

The paper discusses a significant and actual issue of developing autonomy of the individual. Special attention is paid to adolescent age having high potential for developing autonomy in view of certain changes in the psychological and social sphere of the adolescents. The value of interpersonal interaction in the course of developing adolescent autonomy is shown.

The approaches to the concept of interaction are analyzed, four main directions of explaining the essence of interaction are allocated: symbolical interactionism (J. Mid), social exchange (J. Homans, G. Blumer), sociodramatic touch (E. Goffman) transaction analysis (E. Berne). Types of interaction, efficiency of interaction development are considered.

The analysis of interpersonal interaction issues shows its communication with the categories of «relation», «communication» and «joint activity» (B.G. Ananyev, G.M. Andreyeva, S.V. Dukhnovsky, Ya.L. Kolominsky V.N. Kunitsyna, V.N. Myasishchev, B.D. Parygin, etc.). The concept of interpersonal interaction system of the autonomy causing development of adolescence in the paradigm of psychologist-teacher interaction, and also child-parent interaction is described. The advantage of psychological assistance and pedagogical support within the system of interpersonal interaction for further development of adolescent autonomy is proved.

The value of cooperation as one of the types of interpersonal interaction in the course of adolescent autonomy development is shown. Mechanisms of interpersonal interaction, nature of contact in interpersonal interaction, components of a social situation are described.
