A large-scale study of academic specialization and sex effects on Corsi block performance
This study aimed to investigate the relationship between sex, educational specialization (science, technology, engineering, and mathematics (STEM) vs. non-STEM), and performance on the Corsi block-tapping task (CBT). Behavioral outcomes included the total number of correct responses, mean reaction time (RT), and mean RT for correct responses. The sample comprised 5,455 first-year Russian university students (mean age = 18.5; 62% female). Data wer…
Psychometric evaluation of the abbreviated math anxiety scale in Russian university students
Math anxiety can hinder learning and deter students from pursuing STEM fields. The Abbreviated Math Anxiety Scale (AMAS) is a short measure of math anxiety, but its use among Russian university students has not been previously evaluated. We assessed the psychometric properties of the AMAS in a sample of 6,337 Russian first-year university students (mean age 18.6 ± 0.96; 64.4% female). Confirmatory factor analysis indicated that a bifactor model—w…
Perception of Parental Attitudes and General Academic Achievement of High School Students
Objective. Cross-cultural analysis of the perception of parental attitudes and its influence on the general academic performance of high school students from Russia and Kyrgyzstan. Background. The characteristics of parental attitudes are closely related not only to the child’s educational success during life in the family, but also to educational achievements in the future. At the same time, the sociocultural specifics of parent-child relationsh…
A Study of Correlations Between Newborn Children Outcomes and Emotional States and Attachment to a Fetus in Women Pregnant Using in-Vitro Fertilization
Children's development in the early years is significantly linked to further wellbeing. Among many factors involved in early development are mother’s attachment to the fetus and her emotional state during pregnancy. The current study prospectively explores mothers’ characteristics during the third trimester of pregnancy and their newborn children outcomes. The sample included 300 women with natural conception (NC) and 127 women with in-vitro fert…
Engagement Assessment for the Educational Web-Service Based on Largest Lyapunov Exponent Calculation for User Reaction Time Series
Contemporary digital platforms provide a large number of web services for learning and professional growth. In most cases, educational web services only control access when connecting to resources and platforms. However, for educational and similar resources (internet surveys, online research), which are characterized by interactive interaction with the platform, it is important to assess user engagement in the learning process. A fairly large bo…
The development of number line accuracy in elementary school children
BACKGROUND: Number line accuracy (NL accuracy) shows improvement over the course of a school education. However, there are practically no cross-country longitudinal studies of NL accuracy over the whole course of elementary school. AIMS: This study investigated the developmental trajectories of NL accuracy and its types across the elementary school years in two countries-Russia and Kyrgyzstan. SAMPLE(S): The analyses were carried out on the data …
Fluid Intelligence Test Scores Across the Schooling
The results of the analyses of the changes of fluid intelligence scores measured by the Standard Progressive Matrices test across all school years were presented. Sex differences in fluid intelligence scores for each year of schooling as well as in fluid intelligence changes across schooling were analyzed. A total of 1581 participants (51.1% boys) aged 6.8 to 19.1 years from one public school were involved in this cross-sectional study, of whom 8…
Factor Structure and Psychometric Properties of Brief Cope in Russian Schoolteachers
This study investigates the psychometric properties of brief COPE in Russian schoolteachers. A total of 773 (91% female; M = 43, SD = 9.79) teachers participated in the study. Principal component analysis (PCA) and confirmatory factor analysis (CFA) were applied to assess the psychometric properties of the brief COPE. The Perceived Stress Scale (PSS) was used to assess the construct validity. The main result of the current research is a revised s…
The nature of the association between number line and mathematical performance
BackgroundThe number line task assesses the ability to estimate numerical magnitudes. People vary greatly in this ability, and this variability has been previously associated with mathematical skills. However, the sources of individual differences in number line estimation and its association with mathematics are not fully understood.AimsThis large-scale genetically sensitive study uses a twin design to estimate the magnitude of the effects of ge…
Twin classroom dilemma
There is little research to date on the academic implications of teaching twins in the same or different classroom. Consequently, it is not clear whether twin classroom separation is associated with positive or negative educational outcomes. As a result, parents and teachers have insufficient evidence to make a well-informed decision when twins start school. This study addresses two research questions: Are there average positive or negative effec…
Number sense and mathematics
Individual differences in number sense correlate with mathematical ability and performance, although the presence and strength of this relationship differs across studies. Inconsistencies in the literature may stem from heterogeneity of number sense and mathematical ability constructs. Sample characteristics may also play a role as changes in the relationship between number sense and mathematics may differ across development and cultural contexts…
The Correlation Between G Loadings and Heritability in Russia
The study focused on the extent to which the general factor of intelligence g and heritability coefficients of the subtests of an IQ battery correlate. Modest to strong positive correlations were found in five studies from Western countries and six studies from a Japanese meta-analysis. The results for Russian twins were compared with those of the Western and Japanese studies. Data from 402 twins aged 13 and 296 twins aged 16 showed correlations …
