Predictive Assessment

In the article, it is shown that mental performance can be used to predict the degree of tension in track and field students under the influence of emotional stress associated with passing the exam. During the exams, there was a decrease in the statokinetic stability of the students' body, which led to an increase in erroneous answers of students and a decrease in the indicators of mental performance and work productivity, which remained reduced even a week after the end of the exam. The work also shows that a decrease in statokinetic stability is a factor of destabilization of the optimal level of mental performance and productivity of performing cognitive tasks.

The Impact

Introduction. In this study, there were examined features of the impact of exam stress on mental performance and anxiety level in 2-3 year students of medical and pedagogical universities. Materials and methods. The levels of reactive and personal anxiety were studied according to the C. Spielberger anxiety scale adapted by Yu. L. Khanin, attention was assessed using the Pieron-Rüser test, the Bourdon-Anfimov correction test was used to study the level of mental performance, the type of temperament was determined using a two-factor model of extraversion and neuroticism using questionnaire H.J. Eysenck. The study was implemented in two stages: the first stage - during the semester period, and the second stage - during the examination session. For processing the data obtained during the study, a standard statistical software package was used, and correlation analysis was used to identify the relationships between the variables studied. Results. The assessment of situational anxiety in the second stage showed a statistically significant increase in the number of students with high and extremely high levels of anxiety in 24 and 3 respondents from the 1 group respectively (p ≤ 0.05), and 17 and 3 respondents in group 2, respectively (p ≤ 0.05). Correlation analysis of the relationship between reactive anxiety and mental performance showed a weak and medium correlation among students in both groups. The attention study in both groups showed that in the second stage of the study, the indices change: in 1 group, the proportion of students with a low level of attention increased to 40%, and in 2 the number of students with low and very low level of attention decreased by 2.77% and 11.08%, respectively (p ≤ 0.05). Conclusion. Increased study loads and requirements for students were proved to contribute to an increase in the level of reactive anxiety, in the period between sessions indices of mental performance in students decrease, respectively, and the level of attention declines.

The aim of this research was to study the peculiarities of heart rate variability (HRV) and microcirculation in students, depending on their sport specialization. Methods and Results: Our study included the results of a survey of 96 students from 18 to 21 years of age who were the members of the national teams of their universities in athletics (n=49) and floorball (n=47). For ECG registration and analysis of hemodynamic findings, including those characterizing the HRV, we used the “Medical Soft” sports testing system (“MS FIT Pro”). For monitoring, we used the standard hemodynamic patterns (blood pressure, HR, stroke volume, cardiac output, and others), statistical and spectral indicators of the HRV, as well as an integral criterion of the state of microcirculation. The studied HRV parameters in most students generally were within the age range. At the same time, track and field athletes have large adaptive resources and, consequently, a more optimal level of myocardial fitness, in comparison with floorball players. Conclusion: The orientation of sports training among students affects heart condition.

Examination Stress

Exam stress is one of the numerous causes of complex psychophysiological stress in students. One of the modern problems of electrophysiology is the study of the action mechanism of high levels of anxiety in students during and after the examination. The speed of development of the lifestyle of young people and an increase in the level of stress in the environment lead to a change in the relationship in the adaptive function of the body and the emergence of various kinds of deviations. Examination stress is accompanied by the emergence of many complex neurophysiological changes in the body, which negatively affects the life of young men. In all cases, young people strive to achieve their goals, which in itself leads to emotional stress. One of them is the study of the functioning of the nervous system during emotional stress and clarification of the role of various types of the higher nervous system in this. Despite a comprehensive study of this problem, this issue still remains relevant, and the study of the mechanisms of the anxiety process continues. The article presents the results of changes in the level of situational and personal anxiety of the examination process on the indicators of the autonomic nervous system in I and V year students, at the age of 17-21 years, having a type of phlegmatism. Before the beginning of the experiment, the type of temperament was determined by G. Eisenk test. Material and methods. To determine the level of situational and personal anxiety (emotional tension) of 17–21-year-olds, having the phlegmatic type of temperament, we used the method of expressive test two days before the exam, 30 minutes before the exam and 30 minutes after the exam. In all three groups, arterial pressure was measured using the Korotkova method and pulpator method of determining the heart rate per minute. Vegetative tone was calculated based on the Kerdo vegetative index. Results and discussion. The obtained results showed that 17-year-old phlegmatics-first-year students observed differences between the frequencies of cardiac contraction and arterial pressure two days before the exam, 30 minutes before the exam and 30 minutes after the exam. In all groups, the test had a sympathetic character, which testifies to the superiority of the sympathetic nervous system in the duration of the entire examination period. In 21-year-old students-phlegmatics course-vegetative indicators in two days before the exam, 30 minutes before the exam and 30 minutes after the exam differred slightly in comparison with 17-year-olds. Similarly, the Kerdo vegetative index of the 17-year-old students-phlegmatics and 21-year-old students-phlegmatics in all groups had the sympathetic character. This is also evidence of the prevalence of a sympathetic disorder of the sympathetic process used to optimize academic performance, correction of exam stress and protection of students' health

Effects of four retest-practice sessions separated by 2 h intervals on the relationship between general intelligence and four reaction time tasks (two memory tests: Sternberg's memory scanning, Posner's letter comparison; and two attention tests: continuous attention, attention switching) were examined in a sample of 83 male participants. Reaction times on all tasks were shortened significantly. The effects were most pronounced with respect to the Posner paradigm and smallest with respect to the Sternberg paradigm. The relationship to general intelligence changed after practice for two reaction time tasks. It increased to significance for continuous attention and decreased for the Posner paradigm. These results indicate that the relationship between psychometric intelligence and elementary cognitive tasks depends on the ability of skill acquisition. In the search for the cognitive roots of intelligence the concept of learning seems to be of importance.

Abstract. Pharmacological neuroenhancement, defined as the misuse of prescription drugs, illicit drugs, or alcohol for the purpose of enhancing cognition, mood, or prosocial behavior, is not widespread in Europe – nevertheless, it does occur. Thus far, no drug has been proven as safe and effective for cognitive enhancement in otherwise healthy individuals. European studies have investigated the misuse of prescription and illicit stimulants to increase cognitive performance as well as the use of tranquilizers, alcohol, and cannabis to cope with stress related to work or education. Young people in educational settings report pharmacological neuroenhancement more frequently than those in other settings. Although the regular use of drugs for neuroenhancement is not common in Europe, the irregular and low-dose usage of neuroenhancers might cause adverse reactions. Previous studies have revealed that obtaining adequate amounts of sleep and using successful learning techniques effectively improve mental performance, whereas pharmacological neuroenhancement is associated with ambiguous effects. Therefore, non-substance-related alternatives should be promoted to cope with stressful situations. This paper reviews the recent research on pharmacological neuroenhancement in Europe, develops a clear definition of the substances used, and formulates recommendations for practitioners regarding how to react to requests for neuroenhancement drug prescriptions. We conclude that monitoring the future development of pharmacological neuroenhancement in Europe is important to provide effective preventive measures when required. Furthermore, substance use to cope with stress related to work or education should be studied in depth because it is likely more prevalent and dangerous than direct neuroenhancement.

Abstract. Fighter pilots may be exposed to extended flight missions. Consequently, there is increasing concern about fatigue. We investigated the effects of fatigue and cognitive performance in a simulated 11-hr mission in the 39 Gripen fighter aircraft. Five cognitive tasks were used to assess cognitive performance. Fatigue was measured with the Samn–Perelli Fatigue Index. Results showed that performance in the non-executive task degraded after approximately 7 hr. Fatigue ratings showed a matching trend to the performance in this task. Performance in tasks taxing executive functions did not decline. We interpreted that fatigue can be overridden by increased attentional effort for executive tasks but not for non-executive components of cognition. Participants underestimated their performance and metacognitive accuracy was not influenced by fatigue.
