Nowadays, most children attend supplementary classes. This research attempts to review and summarize the results of 14 international studies on the influence of music lessons on children aged 5-12. The paper considers the influence of music lessons on the development of regulatory functions and language abilities. The authors conclude that music lessons have a significant influence on the regulatory functions of children, especially on inhibition and working memory. The relationship between language and music classes highlighted in numerous studies are discussed. With prolonged daily music lessons, children can develop vocabulary and phonological awareness.

The efficiency of performance in various sports has the development of certain specific skills at its core. In ice hockey, both the technical aspects (techniques, stance) and the cognitive ones (keeping attention on the puck, game strategy, etc.) are highly important. This study is aimed at the identification of specific features that determine the performance efficiency of professional hockey players. We used virtual reality (VR) to study the differences between professional ice hockey players and novices in terms of motor responses to the puck’s presentation on different levels of difficulty. The study involved 22 participants, 13 of them being professional ice hockey players (Mage=20±2.9; mean age of training experience М=14.18±3.8) and 9 being not experienced participants (Mage=20±1.4). The study showed that the stick response time of professional hockey players is significantly higher (0.98 ms vs 1.5 ms, p≤0.05) in more difficult situations close to a real game. Moreover, professionals proved to have more stable movement patterns of the knee and hip joints. They also make fewer head movements as a response to stimuli during all runs (0.66 vs 1.25, p≤0.05). Therefore, the results indicate specific spatial-temporal, technical and tactical, and energetic determinants, that ensure higher performance efficiency in hockey players

To achieve high results in sports, both motor and cognitive skills are important. However, the formation of cognitive components of sports activity can be influenced by personality traits, for example, such a multidimensional trait as perfectionism. The aim of the research was to determine the relationship between various parameters of perfectionism and the cognitive component of skill in sports. The study involved 311 athletes aged 14 to 32 years (M = 19.5; SD = 2.03). The following instruments were used in the study: The Sport Multidimensional Perfectionism Scale 2 and The Three-Factor Questionnaire of Perfectionism (for diagnosing perfectionism); Questionnaire of Metacognitive Involvement in Activities (for diagnosing metacognitive involvement); and The Mental Image Inventory in Sports (to determine the frequency of using mental images). It has been shown that the athletes with more pronounced perfectionism are able to better understand and evaluate their performance; they can more accurately notice mistakes and more often use mental images in the training process. Also, as a result of a series of regression analyzes, it has been found that such parameters of perfectionism as “high personal standards” and “regime organization” affect the frequency of using cognitive and motivational images, as well as metacognitive involvement in the activities of the athletes who took part in the study. Thus, perfectionism has a significant impact on various parameters of the cognitive component of skill development, which in turn can affect the performance of an athlete in training and competition.

Coping behavior plays a significant role in the recovery of an injured athlete. Identifying the features of coping behavior can make an invaluable contribution to the development of such a problem as the psychological rehabilitation of an athlete. The objective of this study was to examine the features of coping behavior of injured athletes. The study sample consisted of 279 professional athletes of various sports, who, for the purposes of the study, filled out the following questionnaires: a balanced scale of life satisfaction (basic needs) and a scale of emotional state of E.Diener and a COPE questionnaire designed to measure situational coping strategies and dispositional styles. Depending on the gender, the classification of the sport, the number and severity of injuries, the athlete gravitates towards different coping strategies. We have found a link between the general well-being of the injured athlete and coping strategies such as positive reformulation, emotional focus, and humor. Based on the results of the one-way analysis of variance, we partially confirmed our hypothesis that there are differences in the coping strategies used by athletes representing different categories: gender, sport classification, number of injuries, and severity of injury. The performed correlation partly confirmed our assumption that there is a relationship between the general well-being of the injured athlete and the coping strategies used. Despite the fact that the correlation coefficients showed low values, we believe that this is due to the heterogeneity of our sample.

Relevance. Due to the rapidly changing living conditions, self-regulation skills are the most important components of personality that allow to adapt to reality faster and organize activities inthe most successful way. Th is becomes especially relevant for teenagers who are involved in a large number of classes and projects, in addition to their main activities at school. Objectiveis to study the features of regulatory functions and their interrelations with various personality characteristics in adolescents engaged in scientifi c activities. Study. Th e study involved 78 adolescents aged 14–17 years (Mage = 15, 96; SDage = 1.01) who were trained in the framework of the “Big Challenges” project of the SIRIUS educational Center in the direction of “Science’ in 2021. Several methods aimed at studying self-regulation, stress levels, subjective well-being and perfectionism in adolescents were chosen as diagnostic tools. Results. It was shown that the level of self-regulation of adolescents in activity is better developed than their level of emotional self-regulation. It was also demonstrated that the level of general self-regulation in adolescents involved in science is signifi cantly interrelated with indicators of resilience and self-directed perfectionism. Conclusion. Th e study confi rmed the importance of studying the features of self-regulation in adolescents and revealed the need to develop practical recommendations for their development.
