Mechanical Properties of Lumbar and Cervical Paravertebral Muscles in Patients with Axial Spondyloarthritis: A Case-Control Study.

Background: Axial spondyloarthritis (axSpA) affects spinal muscles, due to inflammation and structural damage. The mechanical properties of the muscles, such as tone or stiffness, could be altered in axSpA. The aim of this work is to analyze the mechanical properties of cervical and lumbar spine muscles in axSpA patients and their relationship with metrology measures, function, disease activity, structural damage and quality of life. Methods: axSpA patients and age/gender/BMI matched healthy controls were recruited. The muscle mechanical properties (MMPs), such as tone or frequency, stiffness, decrement (linear elastic properties), relaxation and creep (viscoelastic properties), of cervical (semispinalis capitis) and lumbar (erector spinae) muscles were bilaterally measured at rest using myotonometry. Additionally, conventional metrology, BASMI (metrology index), BASDAI (disease activity index), mSASSS (radiological structural damage index) and SF-12 (health-related quality of life questionnaire) were used in the axSpA group. Between-groups comparison, intra-group correlations and multivariable regression analyses were performed to achieve the study aims. Results: Thirty-four axSpA patients (mean age: 46.21 ± 8.53 y) and 34 healthy volunteers (mean age: 43.97 ± 8.49 y) were recruited. Both in cervical and lumbar spine, linear elastic parameters were significantly higher in axSpA patients in comparison with controls, while viscoelastic parameters were significantly lower. Lumbar muscle frequency, stiffness, relaxation, creep and cervical muscle elasticity were fair to strongly correlated (|0.346| < r < |0.774|) with age, functional status, activity of disease, structural damage and quality of life in axSpA patients. Furthermore, moderate to good fitted multivariate models (0.328 < R2 < 0.697) were obtained combining age, conventional metrology, activity of the disease and function for the estimation of cervical and lumbar MMPs. Conclusion: Mechanical properties of spinal muscles of axSpA patients differ from controls. Lumbar and cervical muscles exhibit greater linear elastic properties and lower viscoelastic properties, which are related with age, clinical and psychophysiological features of axSpA.

Cognitive Characteristics of Skilled Badminton Players

Study of the cognitive characteristics of qualified badminton players. 34 qualified badminton players, 12 men and 22 women were test subjects. Testing was carried out individually. Analysis of scientific and methodological liter- ature and world experience shows that the study of psychophysiological characteristics provides additional infor- mation about an athlete’s functional state during training and competitive activities. It is known that sports results largely depend on the individual typological characteristics of a person, as well as on the extent to which these fea- tures are used to realize the entire spectrum of the athlete's capabilities. Activation of higher nervous processes is present in almost all components of sports activity and provides a quick reaction, perception and processing of in- formation, the speed of mastering technical elements and quick switching from one type of activity to another. The study of the cognitive characteristics of badminton players was organized using the hardware-software computer complex "Multipsychometer-05". In our research, the first part of Raven's advanced progressive matrices was ap- plied. It is an express version of the test, consisting of 12 tasks and covers the entire range of possibilities diagnosed by the full test. The main informative indicator of the test is performance − the total number of correctly completed tasks for the entire time of the test (the total number of correct answers). The test execution speed, accuracy, effi- ciency are also determined. The analysis of Raven's progressive matrices showed that qualified badminton players have an average level of productivity, speed and accuracy, a level below the average of test performance. The study of cognitive abilities, taking into account sexual dimorphism, showed that, in terms of speed and quality indicators of cognitive tests, women demonstrate significantly better values in relation to men. General cognitive abilities can be used as diagnostic and prognostic criteria in the selection process for qualified badminton players.

Characteristics of students’ academic adaptation at different levels of education in Russia

Introduction. The relevance of the study is conditioned by the need to find effective ways of adaptation due to changing conditions of education and personality development, as well as to inclusion of students with various educational needs and capabilities in the educational process, including those with disabilities (health limitations) and chronic diseases. Currently, there is no conceptual and systematic elaboration of theoretical provisions and experimental research in the field of academic adaptation. Materials and methods. The materials of the study are articles from Russian periodicals. The research method is theoretical analysis of the problem of academic adaptation at different levels of education. Results of the study. Major studies of academic adaptation in Russia are focused on the problems of determining its criteria, age specificity, factors and conditions for successful adaptation, the development of a diagnostic tool, its characteristics in inclusive education, etc. The specificity of academic adaptation at different levels of education is associated with gaining experience of adaptation and psychological development of a student. The determinants of academic adaptation differ depending on the educational level. In the conditions of preschool education the determinants are games and the experience of interaction with peers and adults, psychosomatic development; in the conditions of primary education the determinants are communication skills, educational motivation, interaction with the teacher; in the conditions of secondary education the determinants are correspondence of the educational process organization with characteristics and capabilities of students, interaction with peers and adults; in the conditions of special professional education the determinants are psychophysiological characteristics of students, personality factors (academic motivation, self-reflection), interpersonal factors. Discussion and conclusion. Analysis of academic adaptation as a multicomponent phenomenon makes it possible to develop means of its optimization and to create conditions for children and adults’ academic success in the educational system. Within the context of modern education it is important to study students’ academic adaptation in an inclusive educational environment, the development of the concept of academic adaptation as a process of successive change of its foundations, factors and mechanisms at different educational levels.

The Role of Junior Adolescents' School Well-Being/Ill-Being Characteristics in School Anxiety Variations.

Difficulties that junior adolescents (aged 11–13 years old) experience in terms of academic adaptation, which are indicated through school anxiety and academic wellbeing characteristics, often lead to a dramatic decrease in academic performance, behavioral problems, and deterioration of their health. The purpose of this investigation is to determine the structure of characteristics of school wellbeing/ill-being of junior adolescents and their role in variations of school anxiety, which largely define academic adaptation. In this study, based on positive psychology and a systematic approach, the level of distinctiveness of characteristics of school wellbeing is carried out with the help of comparative analysis; the factor structure of these characteristics is identified; the characteristics of wellbeing and their coordinated combinations (factors) are determined as predictors of school anxiety. The sample consisted of 120 students of the 5th–7th grades, aged M = 11.5; SD = 1.04 (49.2% girls, 50.8% boys) who attended Saratov secondary schools. To study the level of school anxiety, we used the Philips’ School Anxiety Scale (SAS), and indicators of school wellbeing were measured with the original scales developed by the authors of the study. Statistical processing of the results was carried out with regression analysis and factor analysis. The results showed that the school wellbeing of junior adolescents forms a complex structure that includes cognitive, personal, emotional, social, and psychophysiological characteristics of school life. It was found that from 16% up to 53% of the deviation of variables characterizing school anxiety is conditioned by the assessment of variables characterizing emotional states, the ability of self-regulation, cognitive capabilities, and interest in learning. The study determined a high level of tension in adolescents in the field of emotions’ self-regulation, unpleasant physical sensations at school, before and after attending school, in the course of planning their school day and reflecting on educational activities. The most powerful factors of school anxiety in junior adolescents are physical distress, low ability to self-regulate and social adaptation, lack of independence in a learning activity, and personal immaturity.

Correlation of cognitive disorders and catecholamine excretion in anorexia nervosa

The article presents the analysis of correlation and dynamics of clinical and psychophysiological characteristics of the long-term effects of long-lasting abstinence from food on the example of 500 women with anorexia nervosa (AN), who applied for help to the Department of Psychiatry and Medical Psychology, FSAEI HE Peoples’ Friendship University of Russia in 1989-2017. The adverse effects of prolonged abstinence from food are shown; the indicators of catecholamine excretion (dopamine, adrenaline, norepinephrine), encephalography data, mental performance and memory of those examined at various stages of AN weight loss and gain were studied. The difference in the excretion of catecholamines in AN and psychogenic vomiting, which can be used for differential diagnosis, was demonstrated.

STUDY OF THE FEATURES OF THE EMOTIONAL STATE OF ELDERLY WOMEN WITH ISCHEMIC HEART DISEASE

The article highlights the results of an empirical study of the psychological components of the emotional state of elderly women with coronary heart disease (CHD), which covered 135 respondents aged 65 to 75 years with coronary heart disease. The aim of the study was to study the psychological components of emotional states of elderly women that can affect the manifestations and course of coronary heart disease, in particular, alexithymia, anxiety, depression, asthenia. It was found that the components of psycho-emotional states of patients with coronary heart disease consist of a set of psychophysiological factors, including: the specifics of emotionally negative states such as anxiety, depression, asthenia, hostility, etc., and the features of the somatic state, themselves manifestations of coronary heart disease and their concomitant changes in the psycho-emotional sphere, in particular the specifics of the traumatic situation for the patient and her personal characteristics. An empirical study found that elderly women with coronary heart disease are characterized by high levels of anxiety, depression, asthenia, mental stress, irritability, suspicion, resentment, neuroticism, secrecy, emotional lability. It is empirically proven that depending on the gender of an individual with coronary heart disease, the psychological components of emotional states differ significantly. It has been studied that women with coronary heart disease have a high level of lability and unstable emotional state. It is established that the emotional state changes rapidly depending on the factors of external and internal stimuli. A labile emotional state is a sign of danger in a person's psychological state, so it can be critical for women with coronary heart disease. Due to the qualitative processing of the obtained results, we found that in the three formed samples - CG, ECG and ECG, the results of the study differed significantly. In the experimental group of men there are no such psycho-emotional phenomena as negativism, irritation, suspicion, resentment and guilt; neuroticism. The results of the control group revealed a high percentage of women at risk. In the experimental group of women, which is the main goal of our study, the outlined phenomena had the highest rate. A number of emotions that contribute to coronary heart disease were identified: dissatisfaction with work, education, life in general; experiencing creative failures, defeats in ambitious desires; insult; frustration caused by the sharp destruction of the usual stereotype of life; constant feeling of inner tension; lack of satisfaction in achieving success; fear; chronic anxiety. From this list of feelings it is clear that they all belong to the register of negative feelings, those that create emotional discomfort. All these feelings are antipodes of feelings that are traditionally considered attributes of a healthy heart, such as: love, courage, courage, joy. The above conditions are special for people with coronary heart disease and have significant differences between male and female groups, and therefore they can be considered as psychophysiological features of elderly women with coronary heart disease. Prospects for further research may be the feasibility of creating a comprehensive program of psychocorrection of emotional states of elderly women with coronary heart disease.

The codevelopment of adolescents' and parents' anxiety and depression: Moderating influences of youth gender and psychophysiology.

In a 2-year longitudinal study of 220 families, we examined how youth gender and adrenocortical and parasympathetic activity moderated reciprocal, bidirectional relations between parent and youth anxiety and depression problems. Maternal anxiety predicted subsequent youth anxiety and depression. Maternal depression predicted youth anxiety and, for daughters and youth with low adrenocortical reactivity, youth depression. Youth depression predicted maternal depression only for youth with high adrenocortical reactivity. There were no associations between paternal and youth psychopathology. Examining youth gender and psychophysiological characteristics that shape the nature of bidirectional influences may inform efforts to identify families at heightened risk for intergenerational transmission of psychopathology.

Программа по профилактике девиантного поведения учащихся начальной школы с применением народных игр

The program belongs to the preventive psychological and pedagogical direction. In this particular version, the program is aimed at preventive and psychocorrectional work with children using folk games. The phenomenon of folk play in the program is used as a technological resource in working with children to develop socialization, adaptive resources, communication skills, and prevention of deviant behavior. It can be applied to almost any school age. In folk games, the following psycho-emotional states are modeled and experienced in safe conditions: fear, aggression, resentment, rejection, power, and being chosen. It is an intensive and safe way to socialize and prevent deviance. If the play stage in the child’s life has not been worked out, then, getting a varied and complex experience of interpersonal communication and interaction in the game, the participant in the game is freed from the already acquired destructive stereotypes and clamps at the emotional and bodily lev-el. Game situations most successfully form the personal qualities set forth in the requirements of the Federal State Educational Standard of primary general education: benevolence, the ability to cooperate, find ways out of difficult situations, be responsible for their actions. This program involves a whole range of psycho-preventive measures, which are aimed not only at the individual psychologi-cal and pedagogical correction of the student’s personality, but also at restoring his social status in the peer group. The folk game, included in the psycho-preventive program as the main attribute, does not require additional material and technical costs and educational and methodological sup-port, but requires serious training on the part of a teacher-psychologist. Here, knowledge is needed about the psychological impact of folk games, the range of their application, age qualification, as well as the psychophysiological characteristics of children of this age in the selection of games, the psycho-emotional load of games, the order of alternation of games.

Experimental Study of Demotivators and Memes Perception Complexity

The article presents the results of a pilot study of the perception of the demotivator and meme genres. It was a part of an experimental study of psychophysiological and psycholinguistic features of perception and understanding of multimodal extremist texts. The aim of the study is to develop and test the hypothesis about the influence of genre on perception of multimodal texts. To test the hypothesis, we analyze the respondents' eye movement data from the main experimental study (n = 60; 31 forensic linguists with anti-extremism practice, 29 non-experts). Research methods were eye-tracking and quantitative data processing. The following statistically reliable data were obtained: compared to memes, respondents looked at demotivators (1) for a longer time, made (2) shorter fixations, (3) with more of them, and also made (4) faster and (5) shorter saccades. These parameters may indicate a denser scanning pattern of viewing demotivators compared to memes and greater cognitive expenditure in assessing the semantic content of demotivator texts. The results of the study suggest a connection between genre and the degree of multimodal texts perception complexity. This provides an opportunity for further research in this direction and, in the future, will enable the development of norms of cognitive load of judicial linguists who analyse multimodal extremist texts.

Theoretical Foundations of Psychological and Physical Rehabilitation of Patients with Ischemic Stroke

The objectives of our article are: to study the characteristics of disorders of psychomotor function and psycho-emotional state of patients with ischemic stroke according to the initial examination; to develop a method of physical rehabilitation of patients with ischemic stroke at the inpatient stage of rehabilitation, depending on the severity of psychomotor functions and features of the psycho-emotional state; in a psychological and pedagogical experiment to evaluate the effectiveness of the proposed method of physical rehabilitation of patients with ischemic stroke at the inpatient stage of rehabilitation. The following theoretical methods of the research were used to solve the tasks formulated in the article: a categorical method, structural and functional methods, the methods of the analysis, systematization, modeling, generalization. Also in our research we used empirical methods, such as the observation, the interview, the questionnaire, the method of psychological observation, psychological and medical experiment, testing (M. Lucher’s test is used). The results of the research. It was developed a «Functional methodology for the restoration of motor function of patients with ischemic stroke, taking into account their psycho-physiological features», based on the psychological principles of stepwise, sequencing and complexity, as well as on the maximum and adequate psychological impact of the rehabilitation therapist on the patient. Also we proposed the «Functional methodology of physical rehabilitation in the early period of ischemic stroke». The main provisions of this methodology are: 1. The stabilization of the psycho-emotional state of the patient: reducing the level of anxiety, increasing motivation to exercise in the course of physical rehabilitation. 2. The actualization of stable static and dynamic stereotypes of the patient in all initial positions – from horizontal to vertical ones, using the influence of simple, eye-motor, tonic (labyrinthine tonic reflexes, symmetrical cervical tonic reflex, cervical asymmetric tonic reflex, etc.). Restoration and maintenance of stress resistance of patients is provided by symmetrical maintenance of a projection of the general center of gravity on a basic surface in such initial positions in which normal proper afferentation of joints and muscles will be stimulated. These are the positions that the human body consistently takes in the process of verticalization: a supine position on the back; a lying position on the side (right and left); a supine position; a standing position on the knees; a standing position on the knees (with additional vertical support and without such a support); a standing position (with additional vertical support and without such a support). It was proved that the starting position became a directly activated position with a torso extension, which had the aim to support all muscle groups of the patient, provided by the stimulation of a successive chain of muscle contractions directed from the center to the periphery of the body. The symmetry of maintaining the initial position of the patient during the lesson is constantly adjusted (passively or actively) in order to stimulate proper afferentation. Conclusions. The main directions of psychotherapy and psycho-correction of patients who suffered from ischemic stroke are: the assistance in the process of understanding the patients, his / her basic needs, motives, instructions, relationships; his / her internal conflicts and mechanisms of psychological protection; features of his / her behavior and emotional response, their adequacy and realism; the correction of patients’ instructions; the assistance in formulating and securing adequate forms of patients’ behavior based on personal achievements in the cognitive, motivational, and emotional spheres; the promotion of positive motivation for recovery and increased activity in treatment at the behavioral level. During the classes according to the proposed methodology, we have the aim to achieve the stabilization of a psycho-emotional state of the patient through the correction of his / her cognitive processes that motivate the patient to actions which generally affect the effectiveness of all rehabilitation measures.

Modeling of Target Audience'S Intellectual Behavior

The article considers the problems of theoretical substantiation of negative informational and psychological impact evaluation principles, and conducting of relevant researches in this field. At the same time, due to imperfections of theory and practice of negative informational and psychological impact evaluation, previous researches were conducted mainly by “mirroring” the ways of information counteraction, both for our own measures of information and psychological influence, and for the adversary. The rationale for the methodological approaches used in the organization of information and psychological influence is due to inability to access the adversary's target audiences freely and gather the necessary information, as well as the inadequacy of assessing the degree of change in their behaviour. Characteristics mentioned in article classify target audiences according to defined indicators of remote information control of social and individual behaviour of possible objects of influence. Using the formulated conditions and relying on the psychological and psychophysiological characteristics of individuals, a database of target audience behaviour vulnerabilities is forming, that reflects the dependence of indicators of social behaviour perception changes on the intensity of external negative informational and psychological influences. The algorithm of target audience’s information perception is developed based on the model of planned behaviour, in which the subject’s overestimation of small values of probabilities are compared in dynamic with decrease of big ones. The proposed algorithm of evaluation of information-psychological impact allows to receive initial data based on which the model of target audience behaviour will be designed in any environmental conditions.

Psychophysiological characteristics of the features of the establishment of cognitive functions in senior pupils

Introduction. The harmonious development of cognitive processes is a prerequisite for students’ successful mastering of the educational program. The aim of the study is to give a psychophysiological characteristic of the peculiarities of the formation of cognitive functions in senior students. Materials and methods. The study of the functional state of the central nervous system (CNS) by the process of variational chronoreflexometry was carried out in 300 senior pupils of the traditional general education school; the assessment of cognitive abilities and intellectual level development was evaluated by using computer tests. Results. Pupils of the 9th and 11th grades were shown to have no significant differences in the CNS functional indices. In contrast, the CNS functional level was 1.6-1.7 times lower than the physiological norm. The nervous reaction’s stability was 1.3 -1.4 times, the level of functionality of the formed functional system was 1.3 times. The decrease in the level of CNS functioning of the studied adolescents was due to the consumption of reserve functional capabilities of the central nervous system and the body as a whole for the formation of cognitive functions, as evidenced by the development of verbal and non-verbal thinking in students from the 9th to the 11th grade, high speed of thinking processes, voluntary attention and its stability. It was proved that the development of thinking contributed to the formation of voluntary attention, an increase in its stability, and the degree of concentration, confirmed by the established correlation of moderate strength between the accuracy index and the level of formation of various types of thinking (r = 0,4). Conclusion. The established features of students’ intellectual development during a three-year study can be taken into account when organizing the educational process in traditional educational institutions to increase the level of cognitive development and academic performance of students.

Features of Willed Self-Regulation of Students In the Conditions of Distance Learning

Problem and purpose. The article actualizes the problem of the features of volitional self-regulation of girls studying in the specialties of secondary professional education in the context of distance learning. The purpose of the article is to study the psychological characteristics of volitional self-regulation in students in conditions of distance learning using information technologies. Methodology. Methods of empirical research of psychological characteristics of volitional self-regulation of personality, statistical and comparative methods of analysis were used in the work. The study of the problem of volitional self-regulation of the personality allows to solve the problems of correcting the psycho-functional structure of the personality on the basis of which students build an algorithm for the upcoming information, technical and educational activities. In the context of distance learning, volitional self-regulation becomes a decisive condition for the successful mastering of knowledge in solving educational problems and improving professional skills. The results of the study show that most of the students in the specialties of secondary professional education consciously relate to the distance learning mode, show persistence, active independent initiative in mastering the educational material. A low level of volitional self-regulation, self-control, psychological activity and reflection of students causes a decrease in working capacity, does not ensure the sustainability of interest in educational activities, interferes with the implementation of educational tasks, makes it difficult to independently control personal motives for learning, coordinate their actions in accordance with changing conditions. Conclusion. It was revealed that students in the process of adaptation to the conditions of distance learning, depending on the individual, psychophysiological characteristics of the body, use the possibilities of changing the level of volitional self-regulation and psychological activity, which allows them, first of all, to maintain the mental state of emotional comfort, reduce the level of psycho-emotional stress and respond adequately to new learning conditions.

Special attention is paid to such characteristics of the nervous system as emotional stability and information transmission rate in the oculomotor system. Methods for measuring these characteristics using digital and literal texts are presented. The measurements were performed using a device developed by the author. The results of the performed experiments make it possible to solve the problem of occupational selection of operators with appropriate characteristics.

Философия рисков цифровизации образования: когнитивные риски и пути создания безопасной коммуникативно-образовательной среды

The instability of modern civilizational development and the growing risks of constructive socio-anthropological dynamics pose new challenges for philosophical knowledge. The article is devoted to the systemic problem of digitalization of education and the understanding of cognitive risks. The research methodology is based on philosophical, psychological, pedagogical and information technology approaches to the process of digitalization of education, determining the nature and forms of manifestations of cognitive risks. The authors rely on numerous foreign and domestic concepts of informatization (digitalization) of education and focus on several types of risks of the cognitive sphere of students: information over-saturation, devaluation of memory capabilities, reduction in the level of critical thinking. The article emphasizes the probabilistic nature of these cognitive risks, defined by a set of scientific, methodological, organizational, methodological, psychological and pedagogical factors and individual personality, psychophysiological characteristics of students who are vulnerable to these risks to different degrees. The result of the study is a proposal on ways to level the cognitive risks of digitalization of education. The authors call for a balanced strategy and the consolidated work of all subjects of the education system in order to achieve the formation of a safe communicative and educational environment.

Psychophysiological data-driven multi-feature information fusion and recognition of miner fatigue in high-altitude and cold areas

Fatigue-induced human error is a leading cause of accidents. The purpose of this exploratory study in China was to perform field tests to measure fatigue psychophysiological parameters, such as electrocardiography (ECG), electromyography (EMG), pulse, blood pressure, reaction time and vital capacity (VC), in miners in high-altitude and cold areas and to perform multi-feature information fusion and fatigue identification. Forty-five miners were randomly selected as subjects for a field test, and feature signals were extracted from 90 psychophysiological features as basic signals for fatigue analysis. Fatigue sensitivity indices were obtained by Pearson correlation analysis, t-test and receiver operating characteristic (ROC) curve performance evaluation. The ECG time-domain, ECG frequency-domain, EMG, VC, systolic blood pressure (SBP), and pulse were significantly different after miner fatigue. The support vector machine (SVM) and random forest (RF) techniques were used to classify and identify fatigue by information fusion and factor combination. The optimal fatigue classification factors were ECG-FD (CV Accuracy = 85.0%) and EMG (CV Accuracy = 90.0%). The optimal combination of factors was ECG-TD + ECG-FD + EMG (CV accuracy = 80.0%). Furthermore, SVM machine learning had a good recognition effect. This study shows that SVM and RF can effectively identify miner fatigue based on fatigue-related factor combinations. ECG-FD and EMG are the best indicators of fatigue, and the best performance and robustness are obtained with three-factor combination classification. This study on miner fatigue identification provides a reference for research on clinical medicine and the identification of human fatigue under high-altitude, cold and low-oxygen conditions.
