The relationship between the level of preschoolers’ cognitive development and the success of their adjustment to primary school

Introduction. The article studies the problem of children’s adaptation to systematic learning at primary school, which is significant in a rapidly changing world, determining both the conditions of the educational environment and the requirements for the level of preschoolers’ preparation. The purpose of this study is to evaluate the influence of the level of preschoolers’ cognitive development on their adaptation to systematic learning at primary school. Materials and Methods. The methodology of the study is based on a systematic approach that allows the authors to reveal psychophysiological characteristics of the subject, the complex of which provides the most complete picture of the child’s development. The following methods were used: theoretical analysis, synthesis; diagnostic methods, allowing to assess the level of cognitive development and academic performance of the examined children; methods of mathematical statistics for processing empirical data. Results. Through theoretical analysis and generalization of research data, it is shown that the majority of children have developed basic cognitive functions by the older preschool age. However, carrying out a comprehensive diagnosis of the preschoolers’ functional development in preparatory groups, the authors identified low levels of voluntary regulation, visual-spatial perception and visual-motor coordination in a third of the examined preschoolers. Based on the data analysis of these children’ academic performance at primary school, the authors identified influence of the level of the above mentioned cognitive functions in preschool age on academic performance at primary school. Longitudinal analysis showed a gradual increase in academic performance in this group of students by the third year at primary school. Conclusions. Based on the results obtained, the authors showed that the level of cognitive functions development, as well as social and communication skills, significantly influences the successful adaptation of first-year primary schoolchildren and subsequent academic performance at primary school. In conclusion, the authors point out that it is necessary to conduct a comprehensive assessment of cognitive development in older preschool age in order to identify individual characteristics and predict possible risks of maladjustment at school.

Physical fitness as a factor in the effectiveness of the competitive activity of 17-18-year-old football players during the transition to professional teams

The need to demonstrate high results, on which a coach's career depends, forces the latter to practically ignore the psychophysiological features of the body of athletes aged 17-21 during the educational and training process and measures to restore players after exertion. As a result, the demands of professional football for most of the talented youth become excessive, which leads to overfatigue and a high level of injuries. The most rational approach to solving the problem of training football players during the transition to professional teams should be based on a systematic training methodology that will ensure effective development of sportsmanship, systematic growth of functional capabilities and their proper implementation. It should be noted that the indicators of physical and technical fitness of football players after graduating from the children's and youth football school do not meet the requirements of professional football. The article is devoted to solving the problem of the effectiveness of the competitive activity of 17-18-year-old football players during the transition to professional teams. The work revealed that the age range from 17 to 21 years falls on the period of an athlete's life, when the formation of all functional systems, which ensure high performance and immunity of the body against adverse factors that appear during intense training, is basically completed. It was noted that the physical and technical fitness indicators of football players after graduating from the children's and youth football school do not meet the requirements of professional football. The peculiarities of physical fitness in relation to the effective competitive activity of 17-18-year-old football players at the stage of specialized basic training were analyzed. The data of the study served as indicators of the players' physical fitness. As a result of the conducted correlational analysis of the physical fitness of young football players aged 17-18 years, an average and low value of the relationship was determined, which implies a fairly close relationship between the level of physical fitness and almost all indicators of the sportsmen's motor qualities, except for the indicator that characterizes the starting speed. It has been confirmed that the preparedness of athletes in football depends on their functional indicators, which, in turn, determine the effectiveness of certain tactical and technical actions.

INDICATORS OF OCULOMOTOR ACTIVITY AND CEREBRAL HEMODYNAMICS IN STUDENTS WITH DIFFERENT TYPES OF AUTONOMIC NERVOUS SYSTEM REACTIVITY IN COGNITIVE TASK PERFORMANCE

Background. The current stage of human development is characterized by high dynamics of knowledge accumulation, acceleration of social and technical development. The need to study psychophysiological characteristics of cognitive activity with time limitation increases under these conditions. Time limit can make activity more efficient or less effective. Purpose. To study indicators of oculomotor activity and cerebral hemodynamics of students with different types of autonomic nervous system reactivity during cognitive activity. Materials and methods. The study involved 110 students of the Northern (Arctic) Federal University named after M.V. Lomonosov took part in the study (average age of students 19.0±0.5 years). To identify specific features of ensuring cognitive activity in different time conditions, the type of reactivity of the autonomic nervous system (ANS) was determined in the subjects using the VNS-Spectrum computer complex (Neurosoft). Students performed cognitive tasks without and with time limits. At the same time, eye movements were recorded using the stationary binocular eye tracking system iView X™ RED, 500 Hz, and cerebral hemodynamic parameters were recorded using the Reo-Spectrum 2 hardware and software complex (Neurosoft). The efficiency of cognitive activity of the participants was also assessed. Statistical analysis was performed using the application package IBM SPSS Statistics 22.0. Results. Students with different types of reactivity of the autonomic nervous system had different effectiveness of cognitive activity without time limitation and with time limitation. Students with a sympathotonic type of autonomic reactivity had a higher result in processing visual information under time pressure. These students had more stable statistical relationships between the parameters of oculomotor activity and cerebral hemodynamics. Representatives with a vagotonic type of reactivity of the autonomic nervous system had the lowest rates of success in cognitive activity. These students showed less stable structure of statistical relationships between oculomotor activity and cerebral hemodynamics Conclusion. General and specific changes in cerebral hemodynamics and oculomotor activity, features of the effectiveness of cognitive activity under time constraints in young people with different types of autonomic nervous system reactivity were identified.

Examining the relationship between subjective exercise tolerance and psychophysiological reactivity during physical stress.

It has been hypothesized that one's ability to control impulses aids in sustaining effort despite experiencing painful physical sensations. Physical exercise has been used extensively as an intervention to strengthen the inhibitory control system and protect an individual's cognitive plan of action. It is unclear, however, whether the high levels of exercise tolerance could facilitate inhibitory control under varied stressors. The present study explored the relationship between subjective exercise tolerance and psychophysiological characteristics that indicate reactivity capacity when exposed to the cold pressor test. Thirty-six participants were divided into two groups based on their subjective exercise tolerance profiles. During the test, participants' psychophysiological reactivity was monitored via heart rate variability. Participants were also required to answer questions about their perceptual and affective states at the beginning and immediately after the stress test. The study revealed insights into dominance perception and emotional states among individuals with varying subjective exercise tolerance levels. High-tolerant individuals endured physical discomfort longer (~50 s) and exhibited higher perceived dominance at the outset of the test when compared to their low-tolerant counterparts. Despite differences in task performance, both groups experienced more positive affective states post-task, potentially as a result of a heightened sense of self-accomplishment. Notably, both groups showed similar levels of psychophysiological reactivity, suggesting a protective effect of physical tolerance on ensuing biological responses. Overall, this study sheds light on the complex relationship between exercise tolerance, dominance perception, and psychophysiological reactivity during physically demanding tasks, enriching our understanding of how developing physical tolerance may impact inhibitory control under stress.

Impact of controlled physical training on clinicopathological and psychophysiological features of patients with chronic heart failure and type 2 diabetes

Aim. To evaluate the effectiveness of long-term (five-year) supervised physical exercise in patients with chronic heart failure (CHF) following myocardial infarction (MI) and type 2 diabetes mellitus (T2DM).Materials and Methods. The study included 88 patients with CHF of functional class II-III after MI and concomitant T2DM. In addition to standard medication therapy, patients in the main group (n = 42) performed regular moderate-intensity physical exercises for 30−60 minutes at least 5 days a week. The control group consisted of 46 patients who received standard medication therapy. Patients in both groups had similar clinical and demographic characteristics. After 5 years of follow-up, we assessed the incidence of a composite endpoint (death, MI, emergency myocardial revascularization, acute CHF decompensation), quality of life (measured by the SF36 questionnaire), levels of anxiety and depression (measured by the HADS questionnaire), and levels of fatigue (measured by the MFI-20 questionnaire). By the end of the five-year observation period, data were available for 40 patients in the main group (11 patients were excluded from the study due to discontinuation of regular physical exercise) and 42 patients in the control group.Results. The incidence of the composite endpoint was 55.2% and 80.9% in main and control group, respectively (p = 0.038). Regular physical exercise over the five-year period was associated with a higher quality of life according to the SF36 questionnaire (64.5 [63.1; 67.8] vs. 49.2 [48.4; 49.8], p = 0.001), lower levels of anxiety (5.8 [5.1; 7.7] vs. 8.0 [6.8; 9.2], p = 0.042) and depression (2.9 [2.2; 4.2] vs. 10.7 [10.5; 12.3], p = 0.001) according to the HADS questionnaire, and lower levels of general fatigue according to the MFI-20 questionnaire (9.1 [8.5; 11.2] vs. 15.1 [14.5; 15.4], p = 0.019).Conclusion. Long-term regular physical exercise in patients with CHF and T2DM improves cardiovascular outcomes and psychological status of patients.

Methodological aspects of training systems of junior taekwondist

The article analyzes the basis of achievements in the field of promotion of theoretical and methodological bases of sports training on the basis of taekwondo; it is necessary to organize these methodical exercises before the training of taekwondo; the necessity of the processes of natural development and adaptation to the physical advantages of young taekwondo players; the necessity of scientific equipment for the stimulus of training advantages in the minds of emotional states is shown. The specific features of the preparation of taekwondo fighters with the consideration of morphofunctional and psychophysiological features of athletes in the initial-training process are revealed. The most important aspects of taekwondo training or contribute to the optimization of the level of training of athletes are identified. Among the various directly the field of psychophysiology of sports is one of the most promising fields for the search for new approaches to the preparation of highly qualified athletes. The same observation of psychophysiological characteristics gives additional information about the functional state of the athlete for different minds of activity. One of the key nutrients is the prediction of potentially high results in a particular sport on the basis of a comprehensive study of mental and mental strengths and anatomical and physiological tasks. The methodology of SAN can be used to monitor the dynamic emotional state of the athlete, reflected in the indicators of self-esteem, activity and mood during the training period. The results of the psychological test revealed the dependence of the indicators of self-esteem, activity and mood on the indicators of physical activity. The effectiveness and efficiency in taekwondo is determined by the demonstration of high agility, the unprecedented strength of the attackers and defenders, the strength of the tactical and emotional fight. Considering that the effectiveness of taekwondo activities depends on the athlete's ability to jump, we analyze the information that is important to understand the psychophysical functions of the control of the athlete's physical position. this correction of the training process.

Comparative Analysis of Academic, Behavioral, and Psychophysiological Variables in Male and Female Vocational Training Students.

The purpose of this study was to investigate whether or not there are notable differences between male and female vocational training students in terms of academic, behavioral, and psychophysiological characteristics. A total of 411 vocational training students, 210 of whom were male and 201 of whom were female, participated in an online survey that assessed academic, behavioral, and psychophysiological patterns. In terms of extraversion and openness to experience, our research revealed that no statistically significant differences were noticed. When it came to agreeableness, however, significant differences were seen, with female students getting higher marks than male students. Furthermore, we found that there were significant gender differences in terms of neuroticism and conscientiousness, with female students achieving higher scores than male students. When compared to their male counterparts, females displayed higher performance in terms of academic success. They also demonstrated superior values in terms of reported stress, anxiety, and cognitive inflexibility. The findings of this study provide a more in-depth understanding of the numerous factors that have an impact on students engaging in vocational training. This will serve as a foundation for the development of individualized instructional and support programs.

Features of sensorimotor response of students with different types of attitude to the disease: a cross-sectional study

INTRODUCTION. One of the key psychophysiological features of a subject who has lost his health is sensorimotor response, reflecting the features of neuroplasticity, and allowing us to understand how much a person is able to adapt to the changed living conditions that the disease inevitably imposes. In turn, achieving the desired result of rehabilitation will become more effective if, when building rehabilitation measures, it is taken into account how a person with certain health problems treats his changed condition, that is, to determine the type of attitude to the disease of a participant in rehabilitation measures. AIM. To study the features of simple and complex sensorimotor reactions in boys and girls with different types of attitudes to the disease. MATERIAL AND METHODS. 160 subjects (average age — 21 ± 2.3 years) of both sexes were examined. The main criterion for the sample formation was the different level of health of the study participants. Respondents with 2 and 3 health groups were selected. The diagnosis of the types of attitude to the disease was carried out using the “Type of attitude to the disease” technique. The fixation of the sensorimotor response was performed using the Rebus computer technique, which allows recording a simple and complex sensorimotor reaction. RESULTS AND DISCUSSION. It was revealed that harmonious (25 %), anosognosic (10.6 %) and ergopathic (20.6 %) types of attitude to the disease predominate in the group of subjects. Shown: 1) subjects with anosognosic type have the highest accuracy of a simple sensorimotor reaction (−0.12 ± 0.12), compared with the other two identified types of attitude to the disease (p 0.05); 2) subjects with anosognosic type have the lowest values of the average execution time of a complex sensorimotor reaction (361.51 ± 31.14), compared with subjects with a harmonious (386.19 ± 32.18) and ergopathic (396.50 ± 50.05) type of attitude to the disease; 3) the quality (R = 0.299, R2 = 0.090 at p = 0.020) and accuracy (R = 0.293, R2 = 0.086 at p = 0.023) of a simple sensorimotor reaction affect the type of attitude to the disease. CONCLUSION. In subjects with different types of attitude to the disease, the features of sensorimotor response differ from each other. The most effective sensorimotor reactions are performed by subjects with an anosognosic type of attitude to the disease. The type of attitude to the disease and the parameters of sensorimotor response, such as the quality and accuracy of a simple sensorimotor reaction are related to each other.

Features of physiological support for goal-directed activity of people with various individual typological characteristics

The challenge of increasing human productivity in different fields of professional and other activities has become particularly acute in the 21st century. For many years, research into the field of psychophysiology, as one of the areas of medical and biological sciences, has been dedicated to solving a number of challenges related to optimizing human labor activity. However, the results of this work, especially when performed on different models, often present contradictory findings. This article presents both classical and new data on the physiological underpinnings for the goal-directed activity of individuals with various psychophysiological traits. Some of the most commonly analysed psychophysiological traits in the study of goal-directed activity in humans are intro-extraversion, neuroticism and personal anxiety. The behavioral characteristics of people with these individual typological features, and the variability of performance of goal-directed activity, are considered. The article presents data of vegetative support and the parameters of electrical brain activity during the realization of goal-directed activity of individuals with different psychophysiological characteristics.

COGNITIVE PROCESSING AND MEMORY TECHNIQUES IN CONSECUTIVE INTERPRETATION

This study investigates the psychophysiological characteristics and memory utilization in professional translators specializing in consecutive interpretation. Utilizing a comprehensive questionnaire, the study gathered data from practicing translators to understand how mechanical, logical, and imaginative memory strategies impact their translation performance, particularly focusing on spoken information retention over extended periods. Results indicate a strong preference for logical memorization due to its effectiveness in structuring and understanding complex information. However, imaginative memorization also plays a crucial role in scenarios requiring dynamic translation solutions. These findings suggest that training programs should emphasize versatile memory strategies to enhance translation accuracy and efficiency.

PSYCHOLOGICAL AND PEDAGOGICAL APPROACHES TO THE LEARNING ACTIVITIES OF PUPILS WITH DIFFERENT LATERALISATION OF THE CEREBRAL HEMISPHERES

Significance of the order of pair‐wise comparisons in Analytic Hierarchy Process: an experimental study

AbstractThe article describes an approach, ensuring higher credibility of expert estimation results, based on specific order of pair‐wise comparisons. The order of pair‐wise comparisons is, in its turn, based on the distance between estimated objects in the ranking. According to the suggested approach (and some human psychophysiological features), the most ordinally distant objects should be compared before ordinally closer ones. In order to empirically confirm this assumption, a special experiment involving real experts has been conducted. The results of the experiment indicate that if objects are presented to the expert for comparison in the suggested order, then in the majority of cases relative weights of objects, obtained using eigenvector method, most adequately reflect this expert's priorities. Moreover, pair‐wise comparison matrices constructed using the suggested comparison order tend to be slightly more consistent. The suggested approach to re‐ordering of pair‐wise comparisons can be applied as part of the AHP algorithm in weakly structured subject domains, influenced by multiple intangible criteria. It also provides conceptual basis for reduction of the number of pair‐wise comparisons, required to obtain credible results, in AHP without loss or distortion of expert data. It can also be used for modification of combinatorial pair‐wise comparison aggregation method, based on spanning tree enumeration. And, finally, it will improve the overall multi‐criteria decision‐making process in diverse subject domains, characterized by high uncertainty levels.

<p>The purpose of this work is to study the psychophysiological features and characteristics of the activity of the central nervous system in young people with signs of Internet addiction. Young people were investigated, students of grades 10-11 of Tyumen gymnasiums, as well as students of 1-3 courses of Tyumen State University were studied. Internet addiction was determined by the Chen test, the average screen time spent online using mobile gadgets was recorded, the level of anxiety was determined when modeling the symptom of network access cancellation. Cognitive plasticity was determined by the Stroop method. The properties of the central nervous system were studied using a Symbol Cancellation Test (Landolt rings), the critical frequency of the fusion of flickers, the time of simple and complex visual-motor reactions were measured. The following results were found: in gymnasium students with signs of Internet addiction, significant cognitive rigidity was recorded in congruent (1.19 ± 0.05 s per solution; p<0.01 with control) and non-congruent (1.49 ± 0.08 s per solution; p<0.001 with control) Scab samples, respectively. In the group with Internet addiction, low reliability of work on the Landolt test was also noted (Kp 16.24 ± 2.09%; p <0.001 with control), low accuracy of work (At 0.76 ± 0.03 units; p <0.001 with control) and more inert indicators of complex visual-motor reaction (436.66 ± 14.52 ms; p<0.001 with control).The most pronounced negative characteristics associated with low reliability of information processing, low endurance and ability to differentiate in the central nervous system, as well as reduced selective perception of information were noted in the group of gymnasium students and, in part, in the risk groups of gymnasium students and students.</p>

KİÇİKYAŞLI MƏKTƏBLİLƏRİN İDRAK FƏALLIĞININ PSİXOFİZİOLOJİ CƏHƏTLƏRİ

Psychophysiological Characteristics of Identifying Activity of Younger Schoolchildren Summary Studies have shown that children of younger school age learn very complex mental skills and norms of behavior with amazing ease. Junior school age is a period of emotions, accumulation of knowledge, mainly assimilation. Junior school age is a period of gathering, memorizing and assimilating knowledge. Imitation is the source of success in the education of a young schoolboy. Students repeat the judgments of the teacher, give examples similar to those of their friends, etc. Although from the outside it may seem like copying, in fact it helps the child to learn the learning material. But at the same time, it can lead to superficial assimilation of those or other events. It is not typical for children of this age to think about any difficulties and complexities. The direction of the young schoolboy's personality is expressed by his needs and motives. There is still a high demand for game activity, but the content of the game is changing. now, while playing, he writes, solves problems, reads, draws, reads for ten hours. All this is important to consider when organizing training activities. Key words: younger schoolboy, intersubject integration, cognitive activity, psychophysiological features, assimilation, adaptation

Forensic characteristics of the victim in the investigation of malicious failure to fulfill duties of care for a child or a person for whom guardianship or care is established

The aim of the work is a forensic analysis of socio-demographic, psycho-physiological and criminal-legal characteristics of persons who have become victims of malicious failure to fulfill their duties to care for a child or a person for whom guardianship or guardianship has been established.
 The methodological basis of the study is the scientific works of forensic scientists who investigated the identity of the victim, the materials of the investigation of criminal proceedings of the specified category, the analysis of the questionnaires of the National Police employees who took a direct part in the investigation of the malicious failure to fulfill the duties of caring for a child or a person for whom guardianship has been established or care.
 It has been established that the growth of crime, which changes in accordance with socio- economic changes in the state, prompts the search for new forms and methods of crime investigation. One of these directions is the creation of a forensic classification of persons in such a way that, using information about their typical characteristics, it would be possible to solve the general tasks of detecting and investigating criminal offenses.
 It has been established that the increase in the number of specified crimes, which changes in accordance with socio-economic changes in the state, prompts the search for new forms and methods of crime investigation. One of these directions is the creation of a forensic classification of persons in such a way that, with the help of information about their typical features, it is possible to solve the tasks of crime detection and investigation.
 It is emphasized that criminal law features do not play a special role in characterizing a person who is a victim of malicious neglect of child care duties or a person for whom guardianship or guardianship has been established, since the vast majority of victims of crimes of the specified category are minors persons At the same time, the psychophysiological characteristics of the victims should not be ignored, since it is the psychological characteristics, the way of spending free time, etc. that determine the way the crime was committed, the situation and conditions, and are closely related to other elements of forensic characteristics.
 Conclusions. It has been established that there are many ways in which malicious failure to fulfill the duty of care of a child or a person in respect of whom guardianship or guardianship has been established can be committed. Instead, the way the crime was committed depends on a number of factors, including the level of education, intellectual development and other data about the victim. On the basis of the analysis of criminal proceedings, the most typical socio-demographic, psychophysiological and criminal-legal characteristics of the victim were established.

Прогноз суицидального риска у сотрудников силовых ведомств, в том числе военнослужащих

Suicide is a major medical and social concern for law enforcement, a contemporary army included, not only in Russia but abroad as well. In recent years, frequency of suicides and suicidal attempts has been growing among law enforcement officials (LEOs), military personnel included. Therefore, it seems relevant to develop a model for predicting suicide risk. In this study, our aim was to develop a model for predicting suicide risk in LEOs based on express testing results. Our research object was represented by LEOs (n = 591), their average age being 23.71 ± 1.12 years. To assess suicide risk, we used a questionnaire for suicide risk assessment ‘SSR-2’, which is a part of DAP-2 methodology for deviant behavior research, and a clinical-psychopathological method. LEOs’ personality characteristics and their current psychophysiological state were identified by using vibration imaging, a technology for recording and mathematically analyzing micro-vibrations of the head and face. It has certain advantages over its analogues. We determined psychophysiological characteristics, basic abilities (types of Gardner’s multiple intelligence) and moral qualities that differed in people with elevated suicide risk against the control. We identified a difference between unconscious reactions of the examined people to stimuli and declared (conscious) ones, which indicates that LEOs tend to hide any signs of suicidal behavior in them. A mathematical model was built for predicting suicide risk: we developed an integral suicide risk assessment and created a probabilistic nomogram that makes it possible to establish likelihood of suicidal behavior signs with accuracy above 98 % relying on results obtained by a 5-minute express test. Use of this predictive model helps identify those people among personnel who should undergo a profound check-up by a psychological support team. Our research results can serve as a basis for creating an objective concept for diagnostics of suicide risk factors in LEOs.

Психофизиологические особенности студентов с разным уровнем риска интернет-зависимого поведения

Internet addiction is a behavioral problem that is rapidly growing increasingly widespread, especially among higher education students. This study aimed to profile psychophysiological characteristics of students at different levels of risk of developing behavior-modifying internet addiction. We invited 261 students and established their levels of internet addiction using the Chen Internet Addiction Scale, then formed two groups: group 1 — students showing no signs of internet addiction; group 2 — students prone to internet addiction. Students' mental and social health and quality of life were assessed. Compared to the participants from group 1, group 2 students were found to exhibit 1.7 times more intense compulsive symptoms, 1.5-fold stronger withdrawal and tolerance symptoms, and had intrapersonal/health issues and time management problems that were 1.3 and 1.4-fold more grave, respectively; all these factors contributed to their predisposition to internet addiction. The risk of internet addiction in group 2 externalized as greater irritability (1.5-fold higher than in group 1), resentment (1.4-fold higher), feelings of guilt and hostility (1.3-fold more intense), verbal aggression (1.2-fold), stress (1.3-fold), anxiety and negative emotional experiences (1.2-fold), and 1.2 times lower quality of life in terms of its psychological component. The resulting data suggest the need for prevention measures designed to reduce the risk of internet addiction through management of negative emotional states in students with the help of socio-psychological inventory.
