Background. Personal authenticity is a person’s ability to be oneself and coherent in both his/her personality and the circumstances of his/her life (time, place, and life-calling). The sense of one’s true self plays an essential role in peoples’ psychological well-being and life goals. Currently, the theory of authenticity is included in existential psychology, the person-centered approach, and the psychology of the subject, but all of these approaches have some methodological limitations.

Objective. The aim of the current study was to explore the everyday presentations of the true self among the primary school children and adolescents. It was expected that in adolescence, these representations are more differentiated and mature than at an earlier stage of life.

Design. In the exploratory research, 330 respondents took part, including 163 primary school children (74 girls, 87 boys, ages 7 to 11; M = 9.4) and 167 adolescents (78 girls, 89 boys, ages 12 to 17; M = 14.3). A special interview consisting of 11 open and closed-ended questions was developed. The inductive method of content analysis was used.

Results. Differences were found in the frequencies of the categories used by primary school children and adolescents. Older respondents described their true selves in more detail; their evaluations were more positive and often included their social life as an inseparable part of themselves, whereas descriptions by the younger children were more sparse, ambiguous, and individualistic.

Conclusion. The results obtained can help identify the substantial stages of the genesis of the true self. To develop authenticity, these facts should be taken into consideration.

Background. A rich vocabulary supports human achievements in socio-economic activities, education, and communication. It is therefore important to clarify the nature of language acquisition as a complex multidimensional process. However, both the psychological and neurophysiological mechanisms underpinning language learning, as well as the links between them, are still poorly understood.

Objective. This study aims to explore the psychological and neurophysiological correlates of successful word acquisition in a person’s native language.

Design. Thirty adults read sentences with novel nouns, following which the participants’ electroencephalograms were recorded during a word-reading task. Event-related potentials in response to novel words and alpha oscillation parameters (amplitude, variability, and long-range temporal correlation dynamics) were analyzed. Learning outcomes were assessed at the lexical and semantic levels. Psychological variables measured using Amthauer’s test (verbal abilities), BIS/BAS scales (motivation), and the MSTAT-1 (ambiguity tolerance) and alpha oscillation parameters were factored.

Results. Better recognition of novel words was related to two factors which had high factor loadings for all measured alpha oscillation parameters, indicating the role of attention networks and respective neural activity for enabling information processing. More successful learners had lower P200 amplitude, which also suggests higher attention-system involvement. Another factor predicted better acquisition of word meanings for less ambiguity-tolerant students, while the factor which pooled logical conceptual thinking ability and persistence in goal-reaching, positively correlated with acquisition of both word forms and meanings.

Conclusion. The psychological factors predominantly correlated with word-learning success in semantic tasks, while neurophysiological variables were linked to performance in the recognition task.

Background. All life strives to be well, but not all life is well. This suggests that cognition aimed at improving and protecting well-being might share a common core across all life forms: core cognition

Objective. In this first of a two-part theoretical article, we systematically specify the evolutionary core cognition of well-being from the perspective of general living agents. In Part 2 we apply this to identity development and the theoretical approaches to well-being. This first part aims to identify the strategies and conditions for the creation and protection of generalized well-being and describes associated behavioral ontologies.

Results. We defined a set of key terms that, together, specify core cognition. This set comprises quite naturally concepts like agency, behavior, need satisfaction, intelligence, authority, power, and wisdom, which are all derived from the defining properties of life. We derived coping and co-creation as two essentially different, but complementary, behavioral ontologies. Coping is for survival and targeted problem solving and aims to end the need for its activation. Co-creation is for thriving and problem prevention and aims to perpetuate its activation. Co-creation can explain the growth of the biosphere. While both strategies are essential, the successful interplay of their strengths leads to the dominance of one of them: co-creation. Absence of success leads to a dominance of coping: a coping-trap and a strong urge to curtail behavioral diversity. We summarize the key terms of core cognition and the ontologies in two tables with defined terms.

Background. Free will belongs to the category of phenomena that are actively discussed in scientific discourse but are neither verified nor proven false. Free will is studied in philosophy, neuroscience, and psychology. We discuss this pluralism, multiplicity of perceptions, and the parties’ arguments in the theoretical part of this article. We approach the existing polemics from the point of view of a person who is in the moment of making a decision and taking responsibility for it. The usual paradoxes are mitigated if we consider free will through the concepts underlying everyday consciousness.

Objective. Our aim is to introduce into the discussion of free will an understanding of its nature as a construct of everyday consciousness, one which acts as a factor in increasing the personal maturity of vital decisions. We also discuss the arguments of the various meta-positions in the dispute about free will.

Design. Our empirical research was designed as a modification of the experiments on imposed attitudes. The sample consisted of 340 people ages 30–50 years.

Results. The level of maturity of actions by the subjects who received the set for determinism was lower than that of the subjects who received the set for free will (U 5133; p = 0.014).

Conclusion. Our study showed that the stronger a person’s belief in free will, the more personally mature that person’s choices – actions – are; and that the more active that belief in free will, the more effective are their efforts to overcome social pressure.

Background. The development of high-quality human capital is an important objective that involves value orientations, cultural dimensions and psychological characteristics of activity. This article presents a cross-cultural comparison of value orientations and psychological parameters of activity among youth from Russia, Kazakhstan, and Latvia.

Objective. The study addressed three questions: (1) Are there values and attitudes related to the readiness for activity among youth in the three countries? (2) Are there any differences between values and parameters of the psychological system of activity in the Russian, Kazakhstani and Latvian samples? (3) What values and attitudes predict the youth’s readiness for activity in each country?

Design. University students from Russia, Kazakhstan and Latvia were invited to participate in the study. The study sample was selected according to age, sex and period of living in the country. Value orientations, cultural dimensions and attitudes were measured by the VSM, WVS, Basic Values Realisability questionnaires. The PRF, Q-LES-Q, SHS, Self-Organization of Activity, DTR, and SWLS questionnaires were applied to evaluate the psychological parameters of activity. To analyse the relationship between value orientations and psychological parameters of activity, we used analysis of variance, Pearson's correlation coefficient and stepwise linear regression.

Results. The cross-cultural variance was established for most values and cultural dimensions in the Russian, Kazakhstani, and Latvian samples, but Personal readiness for activity only differed on the tendency level between the Kazakhstani and Latvian samples. Different values and attitudes accounted for near 57% of the Personal readiness for activity index in Russia and Latvia, but just less than 29% in Kazakhstan.

Conclusion. The activity of university students from Russia depends on their need for achievement and level of happiness. In the Kazakhstani and Latvian samples, the most important factor was the quality of life enjoyment and satisfaction index

Background. Media reports on armed fights or terror attacks introduce reminders of death into people’s daily lives. When people feel non-specific threats (mortality salience) or specific threats (intergroup threats), they may demonstrate unfavorable attitudes toward national outgroups. The issue is mostly analyzed today in line with Terror Management Theory and Intergroup Threat Theory.

Objective. To examine such threats in the Russian context, and the impact of mortality salience (MS) on attitudes toward national outgroups that induced different levels of perceived intergroup threat.

Design. In two studies, participants watched films and completed questionnaires about social distance, social thermometer, and trust toward “more or less threatening” countries. In Study 1, 120 Russian students were assigned to six groups via experimental design: 3 (MS: terrorist attacks in Europe, terrorist attacks in Russia, or a control group watching a video about dental treatment) x 2 (country: Ukraine and Belarus). In Study 2, 122 participants were similarly divided into six groups, evaluating attitudes toward the USA and China.

Results. Study 1 showed that MS mostly increased unfavorable attitudes toward a country perceived as more threatening (Ukraine) than toward one perceived as less threatening (Belarus). Study 2 indicated the same effect on attitudes toward both more (the USA) and less (China) threatening outgroups.

Conclusion. The results identified contradictory tendencies in MS effect, in line with Terror Management Theory and Intergroup Threat Theory. The findings could be used in improving relationships from an international perspective.

Background. This article analyzes the relationship between sensory-emotional experience inthe process of semantic description of vague visual figures,and the level of conceptual (categorical and generative) abilities.

Objective. The objective of our study was, first, to show the differences in the degree and features of activation of elements of sensory-emotional experience in the process of constructing the meanings of vague visual figures; and, second, to show the relationship of these differences with the level of categorical and generative abilities.

Design.We studied 102 older adolescents ages 15-16 years. The research program included the following methods: 1) "Description of vague figures" (E.Yu. Artemyeva's technique change,1980; 1999); 2) "Generalization of three words" (Kholodnaya, 2012; Kholodnaya et al., 2019); and 3) "Conceptual synthesis" (Kholodnaya, 2012; Kholodnaya et al., 2019).

Results. Our results showed that generative abilities play the leading role in determining the degree of severity and diversity of different modalities in forming visual meanings, as compared with categorical abilities. The transition simulation hypothesis explains the results. However, the embodied character of mental modeling (simulation) is not determined “bottom-up” by the individual’s bodily state or the activity of corresponding brain zones. On the contrary, conceptual (namely, generative) structures determine the form of the conceptual representations from the "top down."

Conclusion. Generative abilities represent the highest level of organization of personal conceptual experience, which acquires a multimodal quality, due to the integral nature of conceptual (generative) structures.

Background. Spatial ability (SA) is a robust predictor of academic and occupational achievement. The present study investigated the psychometric properties of 10 tests for measuring of SA in a sample of talented schoolchildren.

Objective. Our purpose was to identify the most suitable measurements for SA for the purpose of  talent identification, educational assessment, and support.

Design. Our sample consisted of 1479 schoolchildren who had demonstrated high achievement in Science, Arts, or Sports. Several criteria were applied to evaluate the measurements, including an absence of floor and ceiling effects, low redundancy, high reliability, and external validity.

Results. Based on these criteria, we included the following four tests in an Online Short Spatial Ability Battery “OSSAB”: Pattern Assembly; Mechanical Reasoning; Paper Folding; and Shape Rotation. Further analysis found differences in spatial ability across the three groups of gifted adolescents. The Science track showed the highest results in all four tests.

Conclusion. Overall, the study suggested that the Online Short Spatial Ability Battery (OSSAB) can be used for talent identification, educational assessment, and support. The analysis showed a unifactorial structure of spatial abilities. Future research is needed to evaluate the use of this battery with other specific samples and unselected populations.

Background. The most significant features for clinical diagnosis of schizotypal personality disorder (SPD) are cognitive-perceptual and disorganized symptoms. Experimental study of visual perceptual processes is important to elucidate the psychological mechanisms of cognitive-perceptual impairment in SPD.

Objective. To research the performance of visual perceptual tasks in SPD.

Design. Series I and II presented the subjects with visual perceptual tasks with different types of instructions (vague, verbal, or visual perceptual cues). The Wechsler Adult Intelligence Scale (WAIS-R) was also administered. The participants were 39 SPD patients, 36 obsessive-compulsive personality disorder (OCPD) patients (F.21.8, F.60.5 in ICD-10, respectively), and 102 healthy controls.

Results. SPD patients had a significantly lower number of correct answers in conditions of vague instruction and verbal cues in Series I of a visual-perceptual task in comparison with healthy subjects (р ≤ 0.01). With visual perceptual cues in Series II, patients with SPD had the same number of correct answers as controls, whereas OCPD patients had the same number of correct answers as controls with verbal cues in Series I. SPD patients had significantly lower scores in most verbal and nonverbal WAIS-R subtests in comparison with controls. SPD patients differed from OCPD patients in that they had lower scores in the “Information” (p ≤ 0.05) and “Comprehension” (p ≤ 0.05) subtests.

Conclusion. With visual-perceptual cues, SPD patients were able to achieve normative results in the performance of visual-perceptual tasks, whereas patients with OCPD demonstrated lower productivity. In SPD patients, the basic impairments were associated with difficulties in inhibition of peculiar responses, stability of a subjective manner of performance and inability to revise it, low orientation to the model, and slipping into subjective associations with the stimuli.

Background. People with alcohol-addicted parents are at risk of psychoactive addictions, co-dependency, and suicidal behavior. Most studies of these people are aimed at confirming the inevitability of the impact of negative childhood experiences on their lives, and thus do not seek to identify resource factors which would allow them to overcome the negative emotions they experienced. 

Objective. The purpose of this study was to create a model of resource factors which would allow people with alcohol-addicted parents to overcome the negative emotions they experienced. 

Design. The participants were 58 healthy individuals (17 men and 41 women; M=25.2; SD=4.4) whose parents were alcohol addicts (they were participants in the 12-step recovery program "Adult Children of Alcoholics"), and 50 healthy individuals (15 men and 35 women, M=24.2; SD=3.7) whose parents were not alcohol addicts. The participants completed the questionnaires "Interpersonal Guilt," "Family Emotional Communication," and "Coping Strategies," and were interviewed on the resource factors which allowed them to overcome negative emotions. We used the content analysis of the interviews and latent variable modeling to analyze the questionnaires.

Results. The model of resource factors (CFI=0.895, RMSEA=0.064) showed that the rules set by the parental dysfunctional family (the taboo on the expressing emotions, and external well-being) were associated with being unable to recognize current negative emotions and with avoiding problems. The ability to recognize negative emotions was connected with the participant’s willingness to accept responsibility for his/her life. The resource factors which allowed these subjects to overcome their negative emotions included: communication with relatives and friends; keeping a diary of emotions; and participating in recovery programs.

Conclusion. Our model of resource factors explains the mechanism connecting dysfunctional family rules with the resource factors and negative emotions experienced by people with alcohol-addicted parents. 

Background. The Copenhagen Burnout Inventory (CBI) has demonstrated good psychometric properties among different populations, but there is no known data on its validity among Russian-speaking medical students. The CBI-Student Survey focuses only on fatigue, but measures exhaustion in four different life domains: Personal Burnout (PB), Studies-Related Burnout (SRB), Colleague-Related Burnout (CRB), and Teacher-Related Burnout (TRB).

Objective. To investigate the psychometric properties of the Russian version of the Copenhagen Burnout Inventory–Student Survey (R-CBI-S).

Design. A cross-sectional study was carried out among 771 medical students at Astana Medical University (Nur-Sultan, Kazakhstan). Statistical analyses included test-retest reliability, internal consistency, item analysis, convergent and concurrent validity, and confirmatory factor analysis. Concurrent validity was evaluated by bivariate correlations of R-CBI-S with anxiety, depression, and satisfaction with the study.

Results. Test-retest reliability showed an ICC of 0.81. All item-total correlations for the total scale were positive (range 0.31–0.76). The Cronbach’s alpha coefficient was 0.94 (0.896 for PB, 0.884 for SRB, 0.874 for CRB, and 0.926 for TRB). The Barlett’s sphericity test result was significant (p < 0.001), and the KMO measure of sampling adequacy exceeded 0.947. Convergent validity analysis results: PB (AVE = 0.52, CR = 0.87), SRB (AVE = 0.50, CR = 0.87), CRB (AVE = 0.51, CR = 0.86), TRB (AVE = 0.56, CR = 0.88). The R-CBI-S achieved good levels of goodness-of-fit indices (RMSEA = 0.0611; CFI = 0.940; TLI = 0.933).

Conclusion. The test results indicated that the R-CBI-S scale appears to be a reliable and valid instrument. The R-CBI-S may be a useful tool in future research to identify burnout factors based on specific life domains for developing effective prevention measures among medical students.

Background. Dissociation is a generally recognized phenomenon in psychology and psychiatry; however, questions are still not fully resolved about the difference between pathological and normal dissociation, as well as the role of dissociation, depending on its aetiology, in the formation of clinical manifestations of mental disorders.

Objective. To complement the existing data about the significance of dissociation in non-psychotic mental disorders.

Design. Using the Dissociative Experience Scale (DES), we screened 62 patients (13 male and 49 female) from the Non-Psychotic Conditions Inpatient Department of the Udmurt Republican Clinical Psychiatric Hospital (Izhevsk, Russia). Nineteen of the patients had mental disorders of organic aetiology and 43 patients had mental disorders of psychogenic aetiology.

Results. Dissociation at the pathological level was detected in 12.9% of the patients, all of them female. Among patients with psychogenic disorders, the proportion of patients with pathological dissociation was more than three times that of patients with organic disorders. Among the particular dissociative phenomena, absorption had the highest average severity, both in the general sample and in each aetiological group of patients, while dissociative amnesia had the lowest average severity. The highest levels of dissociation were found in young female patients who had never been married. In patients with psychogenic disorders, the average dissociation severity was significantly higher than in the general population, while in patients with organic disorders it was significantly lower.

Conclusion. The dissociation phenomenon may play a significant symptom-forming role in young women suffering from non-psychotic mental disorders of psychogenic aetiology. In the case of organic mental disorders, the severity of dissociative manifestations decreases even below the conditionally normal level, which may indirectly indicate the destruction of dissociative physiological mechanisms by an organic brain process.

Background. Spearman’s law of diminishing returns (SLODR) states that intercorrelations between scores on tests of intellectual abilities were higher when the data set was comprised of subjects with lower intellectual abilities and vice versa. After almost a hundred years of research, this trend has only been detected on average.

Objective. To determine whether the very different results were obtained due to variations in scaling and the selection of subjects.

Design. We used three methods for SLODR detection based on moderated factor analysis (MFCA) to test real data and three sets of simulated data. Of the latter group, the first one simulated a real SLODR effect. The second one simulated the case of a different density of tasks of varying difficulty; it did not have a real SLODR effect. The third one simulated a skewed selection of respondents with different abilities and also did not have a real SLODR effect. We selected the simulation parameters so that the correlation matrix of the simulated data was similar to the matrix created from the real data, and all distributions had similar skewness parameters (about -0.3).

Results. The results of MFCA are contradictory and we cannot clearly distinguish by this method the dataset with real SLODR from datasets with similar correlation structure and skewness, but without a real SLODR effect. Theresults allow us to conclude that when effects like SLODR are very subtle and can be identified only with a large sample, then features of the psychometric scale become very important, because small variations of scale metrics may lead either to masking of real SLODR or to false identification of SLODR.

Background. Psychological burnout is a state of psychological and physical fatigue that shows the effect of work stress on the individual and  negatively affects his/her attitudes towards work. The current study was motivated by the assumption that people who work directly with students with special needs are at the forefront of professions that can create feelings of frustration, and thus may be vulnerable to psychological burnout.

Objective. To identify the level of psychological burnout among professionals working with children with motor disabilities, and how these levels differ according to gender, workplace, years of experience, and the number of children the employees treat.

Design. The sample comprised 195 staff members at the Al-Hussein Society for the rehabilitation of the Physically Challenged and the Cerebral Palsy Foundation in Amman, Jordan. The researchers used the Maslach Burnout Inventory, which consists of three dimensions: emotional exhaustion, depersonalization, and the lack of a sense of personal accomplishment.

Results. We found a low level of psychological burnout among those who work with children with motor disabilities. The level of psychological burnout was low for two dimensions: lack of a sense of personal accomplishment and depersonalization, whereas it was average for emotional exhaustion. The results showed statistically significant differences in the degrees of psychological burnout in its three dimensions according to the employee’s workplace, with higher levels at the Cerebral Palsy Foundation. However, no statistically significant differences were found among the participants due to gender, years of experience, or the number of children they treat.

Conclusion. The low levels of psychological burnout among professionals who work with children with motor disabilities might be due to the psychological and professional support they receive from their institutions.

Background. Organizational behavior plays a significant role in the effectiveness of enterprises specializing in nanotechnology. Its negative side – counterproductive work behavior (CWB) – has not been analyzed sufficiently in this industry. We evaluated different theoretical approaches to this problem.

Objective. To estimate the predominant forms of counterproductive work behavior in relation to dimensions such as the intensity of the nanotechnology industry, seniority in the organization, and the age and gender of the subjects.

Design. We used a descriptive exploratory methodology that analyzes the preponderance of counterproductive work behavior in profile companies throughout the Russian Federation. CWB was assessed through a self-report questionnaire and in-depth interview with each employee. The results were analyzed by correlation-regression analysis in SPSS.

Results. We found significant correlations between the variables “intensity of the nanotechnology industry within the organization”, “seniority of employees within the organization”, “age of employees”, and the total score of CWB. Regarding the CWB dimensions, the highest average of the scores was obtained for “low level of conscientiousness” (mean = 21.75; SD = 2.9), followed closely by “low level of personal development” (mean = 20.53; SD = 3.09). Among the CWB dimensions, it seems that the conscientiousness of the employees plays a key role in the continuation of their professional activity and consequently in the increase of seniority in the organization.

Conclusion. A professional difficulty can be perceived as a challenge by an employee with good physical and/or psychological resilience. Russian nanotechnology companies should evaluate their approach to dealing with employees and mitigate situations that might be unnecessarily stressful. From the data obtained through the semi-structured interview, we found that what happens in a work group is essential in the emergence of CWB. Organizations need clear policies that empower employees to deal with certain work tasks and with employees who engage in specific CWB.

Background. Fatigue is the most common complaint by children both during and after cancer treatment, but in Russia, there is no reliable method for assessing fatigue. 

Objective. To develop a Russian version of the Turkish Scale for the Assessment of Fatigue in Pediatric Oncology Patients Ages 7-18.

Design. Our first step was to translate all the items of the Turkish questionnaire into Russian. Then, through discussion, we created a single proposition for each item. The next step was obtaining expert opinions to assess the validity. Once the expert estimates agreed, a pilot version of the questionnaire was formed. The next step was to collect a large sample of patients to study the reliability and validity of the questionnaire. 

Results. As a result of factor analysis, three factors were identified. The first factor was "fatigue associated with actions;" the second was "fatigue as feeling;" and the third was "fatigue associated with sleep difficulties." The children's and parents’ versions had the same factor structure. 

Conclusion. This study showed the possibility of using the questionnaire in a Russian sample. That’s why it is necessary to continue collecting and analyzing data in this direction. The reliability of the test was also assessed. The reliability of the parent version scored a Cronbach’s alpha of 0.91. The reliability of the children’s version showed a Cronbach’s alpha of 0.93.

Background. In European countries, postpartum depression (PPD) occurs in 13–19% of women. The statistics indicate that postpartum depressive disorders affect up to 300,000 women in Russia annually. There is still an extremely acute lack of psychological comfort provided to women during labor in Russia. 

Objective. To our knowledge, ours is the first study that examines the association between childbirth experience and the risk of PPD in Russia.

Design. We collected data from 190 Russian-speaking mothers, ages 19 to 46, (M = 32 +4.3) two months after their delivery. 

Results. Birth satisfaction and physical well-being two months after delivery were significantly inversely associated with PPD. Birth satisfaction negatively correlated with the perceived severity and unpredictability of labor, and positively correlated with physical well-being two months after delivery. The presence of a partner and a personal midwife or doula at birth was associated with higher birth satisfaction. 

Conclusion. Our results emphasize the significance of childbirth satisfaction in the context of PPD and suggest the importance of individual professional support during labor.

Background. At the beginning of 20^thcentury, the phenomenon of oddity began to be studied. It was defined as a set of characteristics responsible for an individual giving the impression of being unusual, odd, and peculiar. Later, psychiatrists integrated oddity into the concept of schizotypy. Yet, while considered a part of the schizotypy construct, oddity has remained singular  and maintained its status as an independent dimension.

Objective.The present article discusses oddity as a set of particular clinical traits that can be evaluated both by self-report measures and clinical assessment. We  set out to investigate the oddity phenomena as manifested in a clinical sample, in order to delineate key features that constitute this concept.

Design. Seventy-one patients were selected according to a specific set of criteria and subjected to a set of self-report measures (the Schizotypal Personality Questionnaire and the Adult Personality Traits Questionnaire), a clinical interview, and a pathopsychological experiment. A number of cognitive, behavioral, and emotional characteristics were analyzed. An intra-group comparison was carried out in order to clarify the potential differences between the self-reported and clinically assessed phenomenon of oddity.

Results. The study’s first finding was that the SPQ-74 does not identify odd personalities in the general population, as reflected in the fact that the sample’s average scores proved to be low. Secondly, restricted emotionality and a deficit in social interactions proved to be the prevalent characteristics of the sample of “odd” individuals. Furthermore, a set of certain speech peculiarities (word coinage, bizarrerie, etc.) and thinking impairments of various types (distortion of abstraction level and motivational deficit) emerged as prominent characteristics in the majority of subjects. Finally, it was determined that clinical assessment allows for a more comprehensive evaluation of the psychology of odd personalities than self-report measures, due to a number of the personality, temperamental, and cognitive characteristics that the latter tend to exhibit.

Conclusion. “Odd” individuals can be characterized by a number of cognitive, emotional, and behavioral features independent of social perception and relevant to clinical practice; they can be captured more successfully by the application of qualitative methods. Further research is needed to elaborate this set of traits and test this hypothesis on new samples.

Background. This article is devoted to the problem of excessively rigid behavior, which the author has named “fixed forms of behavior” (FFB). This term was suggested to me by the concepts of P. Janet (idéefixe), S. Freud (Fixierung), and D. Uznadze (fiksirovanaya ustanovka– fixed set/attitude). By FFB, the author understands a broad spectrum of behaviors of a person or a group of people, which, according to the cultural norms of a given society for persons of a certain age, gender, and status,have become inappropriate, yet are repeated in situations objectively requiring that they change; the degree of realization and acceptance of the need for this change can vary.

Results. Through literature analysis and the collection of experimental data over many years of research, in which over 1,150 persons took part – 550 healthy subjects and 600 mental patients from a broad spectrum – and on the basis of a biopsychosocionoetic model of the nature of man and his health, and a system-network approach, it has become possible to distinguish the following models to explain the nature of fixed forms of behavior: neurodynamic, energy-economic, phylogenetic, person-environment relationship, dispositional, stressogenic, pathogenic, psychodynamic, learning (behavioral-cognitive), system (an excessively rigid system and structural relations between levels of action).

Background. Visuospatial working memory changes across years of schooling. According to data from the cross-sectional and longitudinal studies available in the literature, conclusions about the linear or nonlinear nature of changes in visuospatial working memory depend on the period of time analyzed and the frequency of the measurements. However, which of the two nonlinear models of functional dependence (e.g., quadratic or cubic) best describes the developmental trajectories of visuospatial memory across schooling is still an open question. 

Objective. The results of statistical analysis of the development of visuospatial working memory in girls and boys across school years from Grade 1 to Grade 11 are presented. Additionally, the relationship between age and years of schooling is investigated, as is the influence of these factors on the developmental trajectory of visuospatial working memory.

Design. This cross-sectional study involved 1,246 pupils who were in Grades 1 to 11 at one public school; their ages ranged from 6.8 to 19.1 years (50.4% were boys). The students’ visuospatial working memory was measured using the computerized “Sequences” test, which is based on the “Corsi block-tapping task” and has been adapted for Russian schoolchildren. Correlations, dispersion analysis, and polynomial regression were carried out, and both linear and nonlinear models of the functional dependence of working memory on years of schooling were tested. 

Results. The results of the multiple regression analysis suggest that number of years of schooling is a more important factor than age with regard to temporal changes in visuospatial working memory. When we introduced “years of schooling” and “age” predictors into a single model, we found the year of schooling  to be the most significant predictor of visuospatial working memory (β = 1.07;p = 0.000).While age remained a statistically significant predictor (β = -0.52;p = 0.008), it did not significantly improve the model characteristics (corrected R² = 0.30; F(2) = 253.9; p<0.01).

The results of the polynomial regression showed that during schooling, the developmental trajectories of visuospatial working memory are nonlinear for both genders. In girls, both the quadratic and cubic models explained 36% of the variance in visuospatial working memory, but the quadratic model had the least number of parameters and the best fit to data. In boys, despite all theoretical models being suitable, the largest percentage of the variance in visuospatial working memory values was explained using the cubic model (R²= 0.31; p = 0.000). Thus, the characteristic of change in visuospatial working memory for girls had a quadratic relationship that stabilized after Grade 8, while for boys, the relationship was cubic, with the period of stabilization between Grades 5 and 6, and then further growth. 

Conclusion. We concluded that the number of years of study is an important factor in the development of visuospatial working memory during the schooling period, but that there are other factors involved as well.
