Gender Differences In Children Research Articles

Behavioral gender differences in school-age children with autism.

This study examined differences in internalizing and externalizing behaviors between school-aged boys and girls diagnosed with autism spectrum disorder (ASD). Eighty-nine children between the ages of 8 and 16years participated in this study: 17 girls (M = 11.5years, SD = 2.3) and 72 boys (M = 11.3years, SD = 2.2). Participantswere matched onthe Autism Diagnostic Observation Schedule, Second Edition and Full-Scale IQ (FSIQ > 64). The results indicated that, girls had higher reported instances of Bullying, less Anger Control, and poorer Emotional Self-Control than boys on the Behavior Assessment System for Children, Second Edition. Groups did not differ on subscales of the Social Communication Scale. While evidence of increased externalizing behaviors is less common in girls, there is evidence supporting these differing behaviors that warrant further research.

Gender Differences in Fundamental Motor Skills Proficiency in Children Aged 3-6 Years: A Systematic Review and Meta-Analysis.

The age range of 3–6 years is considered as a critical period in developing and learning fundamental motor skills (FMS). To make the formulation of future FMS guidance programs more targeted, we examined gender differences in children’s FMS proficiency using a meta-analysis. Structured electronic databases including PubMed, Scopus and Web of Science were systematically searched using key terms, and the Joanna Briggs Institute (JBI) was used to assess the quality of included literature. Finally, 38 articles (39 studies) met the pre-specified inclusion criteria. The results showed that boys had higher proficiency in total FMS and object control skills than girls (SMD = 0.17 (95% CI 0.03, 0.31), p = 0.02; SMD = 0.48 (95% CI 0.38, 0.58), p < 0.00001), and gender differences in locomotor skill proficiency approached significance, trending in favor of girls (SMD = −0.07 (95 % CI −0.15, 0.01), p = 0.09, I2 = 66%). Meta-regression shows that age is associated with gender differences in object control skills (p < 0.05). In addition, through subgroup analysis, we found that boys’ advantage in object control skills increased with age (3 years: SMD = 0.27 (95% CI 0.00, 0.54), p < 0.00001; 4 years: SMD = 0.58 (95% CI 0.38, 0.77), p < 0.00001; 5 years: SMD = 0.59 (95% CI 0.31, 0.88), p < 0.00001; 6 years: SMD = 0.81 (95% CI 0.61, 1.01), p < 0.00001). In this meta-analysis, we found gender differences in FMS levels in children aged 3–6 years. Notably, gender differences in skill proficiency in object control were influenced by age. We recommend focusing on and developing girls’ object control skills starting at age 3.

Parent-Child Discrepancy in Educational Aspirations and Depressive Symptoms in Early Adolescence: A Longitudinal Study.

Adolescents may have educational aspirations that are different from their parents' educational aspirations for them, and such discrepancy may affect adolescents' psychological adjustment. This longitudinal study examined how parent-child discrepancy in educational aspirations relate to depressive symptoms in early adolescents, both concurrently and prospectively, when controlling for parents' depressive symptoms. Moreover, parent and child gender differences in the effects were explored. Data were collected from 3799 students (52.0% boys; Mage = 10.78) and their fathers and mothers when the students were in fifth and seventh grade over 2 years. Polynomial regression with response surface analysis was used to analyze the effects of parent-child aspiration discrepancy on depressive symptoms separately in four parent-child gender dyads. Cross-sectional results demonstrated that for all parent-child gender dyads, congruently higher aspirations were related to lower depressive symptoms, and greater incongruence in aspirations was related to higher depressive symptoms. Moreover, for parent-son dyads, adolescents whose aspirations were lower than those of their parents reported higher depressive symptoms than adolescents whose aspirations were higher than those of their parents. However, longitudinal results further showed that, for father-son dyads only, congruently higher aspirations were related to increased depressive symptoms over time, while for parent-daughter dyads only, greater incongruence in aspirations was related to increased depressive symptoms over time. The findings support the importance of considering parent-child discrepancy when exploring the role of educational aspirations in adolescents' psychological adjustment and call for a more detailed and rigorous analysis and interpretation of this relationship.

Influences of Gender and Socioeconomic Status on Children’s Use of Robotics in Early Childhood Education: A Systematic Review

ABSTRACT Research Findings: This review focuses on the use of robotics in early childhood education (ECE), addressing gender and socioeconomic status (SES) differences in young children’s robotics learning. This review systematically evaluates, synthesizes, and displays the research designs, robotic toys, data collection instruments, research methods, and research findings of 15 studies related to this critical issue published from 1984 to 2021. The findings of the review indicate that children’s robotics-based learning is impacted by gender and their socioeconomic and cultural backgrounds. Boys had a considerably higher level of enjoyment in interacting with robotics than girls. Furthermore, low-income families and low parental education resulted in poor robotics-based learning experiences and outcomes for children. Practice or Policy: It is significant to devote attention to developing effective and inclusive robotics education programs for girls and children from less advantaged backgrounds. More robotics education interventions should be conducted in broader contexts to benefit a wider range of children, especially those from a lower-SES background.

Socioecology shapes child and adolescent time allocation in twelve hunter-gatherer and mixed-subsistence forager societies

A key issue distinguishing prominent evolutionary models of human life history is whether prolonged childhood evolved to facilitate learning in a skill- and strength-intensive foraging niche requiring high levels of cooperation. Considering the diversity of environments humans inhabit, children’s activities should also reflect local social and ecological opportunities and constraints. To better understand our species’ developmental plasticity, the present paper compiled a time allocation dataset for children and adolescents from twelve hunter-gatherer and mixed-subsistence forager societies (n = 690; 3–18 years; 52% girls). We investigated how environmental factors, local ecological risk, and men and women’s relative energetic contributions were associated with cross-cultural variation in child and adolescent time allocation to childcare, food production, domestic work, and play. Annual precipitation, annual mean temperature, and net primary productivity were not strongly associated with child and adolescent activity budgets. Increased risk of encounters with dangerous animals and dehydration negatively predicted time allocation to childcare and domestic work, but not food production. Gender differences in child and adolescent activity budgets were stronger in societies where men made greater direct contributions to food production than women. We interpret these findings as suggesting that children and their caregivers adjust their activities to facilitate the early acquisition of knowledge which helps children safely cooperate with adults in a range of social and ecological environments. These findings compel us to consider how childhood may have also evolved to facilitate flexible participation in productive activities in early life.

Do Gender Conformity Pressure and Occupational Knowledge Influence Stereotypical Occupation Preferences in Middle Childhood?

This study investigates how perceived occupational knowledge, gender stereotypes, and pressure to conform to gender norms influence children’s career interests in a sample of fourth and fifth grade children (n = 178, Mage = 9.78 years, 46.6% girls). Children were interested in and perceived that they knew more about own gender dominated occupations, compared to other gender dominated occupations. Gender moderated the effect of gender conformity pressure and gender stereotypes on interest in female-dominated but not male-dominated occupations. Boys were less interested in female-dominated occupations when they felt pressure to conform to gender norms and held more stereotypical beliefs about those occupations. These results suggest that perceived occupational knowledge is an important, yet overlooked, factor in understanding gender differences in children’s occupational interests.

Gender Differences In School Dropout Due To Insecurity And Harassment In And On The Way To School In Sindh

This research is aimed to explore gender differences in children’s school dropout due insecurity and harassment in and on the way to school in Sindh. The research is designed as a quantitative research. A survey of 5641 school dropout children in Sindh is done with the help of a questionnaire developed by the researcher. The results of the research show that more than 10% of the children have reported that insecurity on the way from home to school is a cause of their school dropout. The result of t-test shows that more girls than boys are reporting to have left school due to insecurity or harassment they are facing either in school or on the way to school.

Prevalence of diabetes mellitus among Uygur children in Hotan Prefecture of Xinjiang, China.

To investigate the prevalence of diabetes mellitus (DM) among Uygur children in Hotan Prefecture of Xinjiang, China, as well as the factors influencing the development of DM. The cluster random sampling method was used to select 5 308 children, aged 4-18 years, from the middle and primary schools and kindergartens in Hotan Prefecture of Xinjiang. The survey methods included questionnaire survey and the measurement of height and weight. All subjects were tested for fasting fingertip blood glucose to investigate the prevalence of DM and impaired fasting glucose (IFG). A total of 5 184 valid questionnaires were collected. Fourteen children (0.27%) were found to have DM, among whom 8 had type 1 DM, 2 had type 2 DM, and 4 had unclassified DM. Twenty-nine children (0.56%) were found to have IFG. There was no significant difference in the prevalence rate of DM and IFG between boys and girls (P>0.05). The prevalence rate of DM was 0.18% in the 4-<10 years group, 0.47% in the 10-<15 years group, and 0.07% in the 15-18 years group (P=0.072).The prevalence rate of IFG in the above three age groups was 0.18%, 0.94%, and 0.42%, respectively, with a significant difference among groups (P=0.007). The proportion of family history of DM and the proportion of overweight/obesity in children with DM were significantly higher than those in children without DM (P<0.05), while the proportion of children with DM who preferred coarse grains was significantly lower than that in children without DM (P<0.05). The prevalence of DM and IFG in Uyghur children in Hotan Prefecture of Xinjiang is relatively low. There is no significant difference in the prevalence of DM among children of different genders or age groups, but the prevalence of IFG in children of different age groups is different. A family history of DM, overweight or obesity, and low intake of coarse grains might be associated with the development of DM.

Parenting practices and oral health behaviors of children in rural Egypt: gender differences in a household survey

BackgroundParenting practices influence children’s health and development. The current study aimed at assessing gender differences in children’s perception of the parenting practices of both parents, and in the association between children’s oral health behaviors and parenting practices.MethodsA cross-sectional household survey of 6–12 year old children was conducted in a rural area in Northwestern Egypt in 2019. Clinical examination assessed caries and gingivitis. The Alabama Parenting Questionnaire assessed parenting practices in five domains (positive parenting, involvement, inconsistent disciplining, poor monitoring and corporal punishment) and the World Health Organization questionnaire assessed oral health behaviors including sugar consumption and daily toothbrushing. Sugar consumption was the dependent variable in linear regression and daily toothbrushing was the dependent variable in logistic regression. Parenting practices were the explanatory variables adjusting for confounders. Effect modification by child gender was assessed.ResultsThe response rate was 94.1% (n = 433), mean age = 9.9 years, 44.1% boys, 17.8% with daily toothbrushing and mean sugar consumption score = 3.4/8. Girls perceived more mothers’ positive parenting than boys (mean = 14.15 and 13.46) and boys perceived more poor monitoring and corporal punishment. Boys and girls differed in the association between sugar consumption and fathers’ inconsistent disciplining, poor monitoring (P = 0.004 and 0.02) and mothers’ corporal punishment (P = 0.02), and also daily toothbrushing and mothers’ involvement, positive parenting (P = 0.05 and 0.02), fathers’ positive parenting (P = 0.02), mothers’ inconsistent discipling and poor monitoring (P = 0.01 and 0.04).ConclusionsThere were differences between boys and girls in perceiving mothers’ and fathers’ parenting practices and in the association between these parenting practices and toothbrushing and sugar consumption.

AGE FEATURES OF DECIDUOUS TEETH CARIES PARAMETERS IN 3-6 YEARS OLD AGED CHILDREN

The aim: Estimation of caries prevalence and intensity, determination for treatment necessity of deciduous teeth in 3-6 years old aged children from Poltava region for further effective development of programs for caries and its complications prevention. Materials and methods: Totally 335 children from 3 to 6 years old of preschool institutions of Poltava and Poltava region aged were examined with the signed accordance of their parents. All children were examined for the prevalence (%) and intensity of caries of deciduous teeth by the Decay Extracted Filling index (DEF index). Quantitative parameters were processed by standard statistic methods. The calculation of the highest caries intensity (Significant Index of Caries) was performed according to the D. Bratthol`s method. The level of dental aid (LDA) was assessed by the DEF index according to P.A. Leus recommendations. Treatment necessity of children was also determined. Results: The research in caries prevalence of deciduous teeth of revealed that the number of children with caries increases with their age. The most significant parameter growth is observed at the age of 4 to 5 years. Carious lesions intensity increases at the age from 4 to 5 and from 5 to 6 years most significantly. Conclusions: The most common indicator in all studied groups was a D-parameter, which indicates low parents awareness about deciduous teeth treatment necessity. That case confirms low level of dental aid (14%) and significant treatment need which is 50.7 %. Affection of molars always exceeds the affection of other groups of teeth. We did not find a significant difference in caries distribution among children of different genders. The obtained results encourage realization of sanitary and educational propagation on the awareness of parents on dental healthcare of their children.

Reciprocal relation between executive function and receptive vocabulary in Chinese preschoolers: Evidence from a two-year longitudinal study.

By using a three-time longitudinal design, the present study focuses on three components of executive function (EF), respectively, to examine whether the relation between EF and receptive vocabulary was reciprocal and whether the direction of the above relation would differ by EF components and child gender. A total of 320 Chinese preschool children were assessed when they enrolled in preschool the first year (T1), the second year (T2) and the third year (T3), respectively. Children's EF was assessed by six computerized tasks, and receptive vocabulary was assessed by the Peabody Picture Vocabulary test (PPVT-4). Data were analyzed in the random intercept cross-lagged panel model (RI-CLPM). Findings provided some support for within-person reciprocal relations between EF and receptive vocabulary, but the reciprocal patterns varied depending on EF components. In specific, inhibitory control/attention shift and receptive vocabulary were reciprocally predicted between T1 and T2, and inhibitory control/attention shift at T2 could significantly predict receptive vocabulary at T3, but not vice versa. In addition, working memory and receptive vocabulary were reciprocally predicted between T1 and T2 and between T2 and T3. Finally, no child gender differences were found in the above relations. Our findings suggest that the instructions and interventions integrating EF and language skills may be an important avenue for enhancing success across skills.

Diagnosis of the Formation of Grammatical Aspects of Speech in Preschool Age

The article theoretically substantiates and experimentally verifies the validity of the developed diagnostics by the method of contrast groups. The relevance of such a study is determined by the lack of development of the problem of diagnosing grammatical aspects of speech in preschool age for Slavic (inflected by nature) languages. It is proved that for a preschool child in the first stages there is no speech activity separately from the subject, so the object of its orientation is not speech activity, but a single semantic whole, an event that is presented in a sentence (sometimes a phrase, discourse). In the following stages, the child's attitude to speech reality changes. This reality is already special, different from the subject. For all stages of speech and speech development of the child is typical limited and unstable nature of orientation to certain aspects of linguistic reality, when the pre-schooler focuses on either the semantic or formal side of speech. At the end of the senior preschool age, gender differences in children's use of adjectives are the most significant. The reason for the active use in speech of adjectives by girls we see both in the psychological characteristics and gender guidelines of adults around them (active use of nouns and adjectives with hypocritical-diminutive suffixes).

Diagnosis, Manifestations, Laboratory Investigations, and Prognosis in Pediatric and Adult Cushing’s Disease in a Large Center in China

PurposeCushing’s disease (CD) is a rare disease that contributes to 70–80% hypercortisolemia, which presents similarities and differences between pediatric and adult patients, and even between male and female patients. However, the comparative study of CD between different age groups and different genders is still insufficient. The aim of the study is to make a systematic comparison to reveal the gender differences in children and adult patients of CD, helping clinicians to provide optimal treatment for different groups of patients.MethodsWe conducted a retrospective research consisting of 30 pediatric and 392 adult CD patients in a single center in Peking Union Medical College Hospital. All 422 patients showed symptoms related to hypercortisolism and received adenoma excision surgery in the department of neurosurgery between 2014 and 2020.ResultsFor the accuracy of diagnosis, the sensitivity of BIPSS at baseline in pediatric patients was lower than in adults (75 vs. 91%, P = 0.054) but increased greatly after desmopressin stimulation (94 vs. 95%). However, the accuracy of lateralization for BIPSS was not preferred for prediction. As for clinical manifestations, growth retardation, weight gain, hirsutism, and acne were more prevalent for children, while for adults, hypertension, osteopenia, glucometabolic disorder, easy bruising, hair loss, and weight loss were more frequently seen. As previously reported, we observed a significant difference between the male prevalence of pediatric and adult patients (50 vs. 17%, P < 0.001), which was possibly caused by the more severe and earlier onset of a series of symptoms. Gender-related comparison showed greater morbidity of nephrolithiasis, hypokalemia, hypertension, easy bruising, osteopenia, and striae for male patients, while irregular menses, hirsutism, and hair loss were more common for female patients. Further analysis showed that the secretory activity of the PA axis was higher for males, presenting as the more remarkable alteration of laboratory parameters and contributing to the more severe clinical manifestations. For patients treated with transsphenoidal pituitary surgery (TSS), the immediate prognosis could be predicted by operation history, invasiveness, Ki-67, and information provided by MRI, including tumor size and Knosp grading. However, we still lack methods to predict long-term prognosis.ConclusionsOur study is the first detailed and systematic comparison between pediatric and adult CD patients. Further exploration of the impact of CD on different genders reveals a more severe and probably an earlier-onset pattern of CD for male patients.

Relations between Fantasy Orientation, Pretense and Parental Attitudes in Preschool Children

Fantasy orientation (FO) refers to the individual differences to the extent that children prefer pretend activities over real ones. In the current study, the relations between children’s FO, pretend play, and parental attitudes towards child's play were examined. Seventy-eight 3- to 4- year-old children and their parents participated in the study. FO was assessed with child interviews and parent questionnaires. Several behavioral tasks were administered to measure pretend play. The parents also completed a questionnaire about their attitudes towards child’s play behavior. The results showed that there are gender differences in children’s FO: Boys preferred real games, thoughts, and activities more often than the pretend ones. However, girls’ pretend and real preferences did not differ. Yet, overall, girls preferred more pretend games, thoughts, and activities and were more fantasy-oriented compared to the boys. Children’s pretend play was not associated with parental attitudes towards play behavior. However, there were associations between pretend play and FO: The amount of time spent pretend playing was correlated with children’s FO. Further, parents’ positive attitudes regarding pretense predicted higher FO in children. Also, only for boys, parents’ stance on the educational value of pretend play predicted higher FO. The findings and implications are discussed.

Вплив кадмію на здоров'я дітей в пренатальний та постнатальний періоди розвитку

The purpose of the study was to analyze on the basis of foreign literature the effects of the toxic action of cadmium on the process of embryonic and postnatal development of the child, which remain insufficiently studied. The consequences of cadmium effect on children remain insufficiently studied, although cadmium is a documented developmental toxicant. The studies show that the placenta is an important target tissue for cadmium toxic effects during pregnancy. The result of the accumulation of cadmium in the placenta is as follows: a decrease in the utero-placental circulation, changes in the integrity of cells of trophoblast and cell migration, a decrease in the synthesis and metabolism of placental hormones, disorder of the placental epigenetic regulation of cell growth, as well as immune and inflammatory signal transmission. The high level of cadmium in the placenta and umbilical cord blood can be a risk factor for deterioration of infants’ state and impact on the development of a child in the future. So far, only some aspects of the toxicokinetics of the placental cadmium and its adverse effect on intrauterine growth and development are known. The level of cadmium in the mother's serum during pregnancy is associated with the risk of premature birth. There are increasing evidence on connection between the effect of cadmium and unfavorable consequences of childbirth, as well as disorders of anthropometric indicators that differ in children of different gender. In the fetus of the female gender body weight at birth tends to decrease, the chest circumference had a tendency to decrease and these indicators corresponded to an increase in the level of cadmium in the mother’s blood. Cadmium acts as an immunotoxic agent from the very early age, even very low levels of cadmium exposure during pregnancy can lead to long-term detrimental consequences for the immune system of offspring and these effects, as well as others depend on the gender. Models to study the effect of cadmium at an early age on the development of diseases in more mature age are developed. The models in mice show that the effect of cadmium on the body leads to an increase in heart mass at birth and programs hypertension development in females in adulthood. Poisoning, which occurs at an early age (in utero and in early childhood), may have a strong influence on the risk of obesity and metabolic syndrome throughout life. The chronic prenatal effect of cadmium is associated with the late development of IQ in children, while prenatal influence of passive smoking has an increased risk of delaying cognitive development of infants aged 6 months. Early mortality from various diseases, including cancer, cardiovascular, respiratory, renal and neurological problems, correlated with intrauterine or early post-natal impact of metal. Conclusion. Cadmium is classified as a potential neurotoxicant, it reaches the brain in the early stages of the development of the fetus and is associated with behavioral and cognitive dysfunction, including bad learning memory in children of early and late childhood. The adverse consequences of the prenatal effect of cadmium for the development of the fetus and subsequent health of children have discovered a number of non-solved problems, the gender should be considered as a risk factor, since cadmium causes specific results that are veiled in mixed on gender investigations

Gender Differences in Children’s Psychological Well-Being in Mainland China: Risk and Protective Factors

Despite extensive research on children’s psychological well-being, little consensus about gender’s influence has been reached. In response, we examined gender differences in children’s psychological well-being in mainland China, along with the gender-based risk and protective factors and their effects on psychological well-being. For a sample, we compiled data with 2466 children aged between 10 and 15 years old derived from the China Family Panel Studies. Among our results, an independent sample t test indicated that girls in China reported higher psychological well-being than boys. A multiple regression analysis revealed that certain protective factors associated with children’s competence and protective factors in their family and school systems could promote the psychological well-being of both boys and girls, while risk factors such as academic pressure and parent–child conflict were detrimental to the psychological health of all children regardless of gender. We discuss gender differences in those risk and protective effects, and with reference to our findings, we propose social service recommendations aimed at boosting the psychological well-being of children in mainland China.

The advantage of daughters in hypogamous families: parental heterogamy and educational outcomes among children of highly educated parents

ABSTRACT Increasing female educational attainment across OECD countries is making hypogamy a widespread phenomenon. This trend provides an opportunity to re-examine the effects of educational assortative mating on children's educational outcomes. This research explores the effects of hypergamy, homogamy, and hypogamy on gender differences in children's expectation of university graduation and actual college graduation. For the first purpose, logistic regression with country fixed-effects is applied to individual-level data from PISA 2015; a similar analysis is carried out for the second purpose with data from the European Social Survey. Three characteristics make us expect higher female advantage among children of hypogamous couples: higher probability of mothers being the main family breadwinner; higher probability of gender value conflict, eventually leading to family breakup and the father's absence; and the possibility that the father's occupation discourages sons from pursuing higher education. A systematic female advantage is indeed found among children of hypogamous couples in terms of expectation of college graduation and actual college graduation. Among the possible mechanisms behind this female advantage, only the father's and the mother's occupation could be explored with the data at hand, but none of them explain this advantage.

Parental Harsh Discipline and Migrant Children's Anxiety in China: The Moderating Role of Parental Warmth and Gender.

The present study examined the moderating effects of both parents' warmth in the relations between parental harsh discipline (psychological aggression and corporal punishment) and migrant children's anxiety and parent and child gender differences in the moderating mechanism in Chinese society. This study used a sample of 477 elementary school-age children and both their parents in Chinese migrant families. We constructed a Structural Equation Model to explore the relation between parental harsh discipline (psychological aggression and corporal punishment) and migrant children's anxiety and the moderating role of parental warmth. Our findings revealed that maternal but not paternal psychological aggression was found to significantly predict boys' anxiety. Moreover, maternal warmth exacerbated the relations between paternal corporal punishment and girls' anxiety. The findings provide partial support for the "healthy context paradox" and highlight the importance of considering how the broader family emotional context may interact with parental harsh discipline to influence child adjustment.

Gender Differences in Children's Exposure to Domestic Violence in Nigeria.

Children’s exposure to domestic violence (DV) remains an understudied problem in African society at present, particularly in Nigeria. This study examined gender differences in children’s exposure to domestic violence based on identified gaps in the literature. Through a cross-sectional research design, data were gathered from 280 Nigerian children with a mean age of 14.14 ± 2.36. Data were collected using a standardized questionnaire. The independent sample t-test was utilized for hypothesis testing, with statistical significance set at p < .05. Although female participants scored a slightly higher mean score, there was no significant gender difference in children’s exposure to domestic violence [t (278) = .67; p > .05]. The authors conclude that there was no statistically significant gender difference in children’s exposure to domestic violence; however, this research informs further exploration into other variables that may affect children’s exposure to domestic violence.

Adaptation of primary school students to educational activities

The peculiarities of the psycho-functional and physical development of primary children school determine the need for strict control over the state of their mental performance and the characteristics of the development of fatigue during the school year. Taking into account the available data in the literature on gender differences in children of the same age in terms of the implementation of educational activities, the state of mental performance of students was assessed depending on their gender. The indicators of mental performance and fatigue of 2nd-grade students involved in a developmental program were determined using proofreading tests (tables by V.Ya. Anfimov) modified by M.V. Antropova with employees. The level of mental performance of students was calculated according to the intensity (the number of viewed signs) and quality (the number of mistakes and % of unmistakable work) of work, taking into account the sex of the subjects at the beginning and at the end of the academic year according to the indicators of the daily and weekly dynamics of the measured parameters. There were found higher indicators of mental performance in girls at the beginning of the school year, determined by both the intensity and the quality of the work performed. At the end of the academic year, significant differences in the estimated parameters, in terms of daily and weekly dynamics in boys and girls are not revealed. The data obtained indicate the adequacy of the intellectual load on students in this educational institution. The results of a comparative analysis of the mental performance of students before and after lessons (the beginning and end of the school year, daily and weekly dynamics) indicate an increase in the mental performance of children due to the educational process and manifested itself, first of all, in the quality of the work performed.
