Considering the current agreement on the significance of executive functions, there is growing interest in determining factors that contribute to the development of these skills, especially during the preschool period. Although multiple studies have been focusing on links between physical activity, physical fitness and executive functions, this topic was more investigated in schoolchildren and adults than in preschoolers. The aim of the current study was to identify different levels of physical fitness among pre-schoolers, followed by an analysis of differences in their executive functions. Participants were 261 5–6-years old children. Inhibitory control and working memory were positively linked with physical fitness. Cognitive flexibility was not associated with physical fitness. The research findings are considered from neuropsychological grounds, Jean Piaget’s theory of cognitive development, and the cultural-historical approach.

The purpose of this study was to fill this gap by examining the relationship between phonological memory in preschool children and their passive (watching TV) and active screen time with using of Smart Screen Technologies such as tablets and phones with a touch screen interface. Study was conducted in two stages: in Time 1, the association between children’s phonological memory, passive and active screen time and family factors was examined; in Time 2 (1 year later) the impact of passive and active screen time on a child’s individual progress in phonological memory development was evaluated. The study enrolled 122 preschool children aged 5–6 years (M = 5.72, SD = 0.33); boys (54.9%). Information on each child’s average daily passive and active screen time was obtained from a survey with the mother. The survey provided information on how much time each child spent on a typical day with passive (“traditional”) and active (interactive) use of digital devices. For family factors, we included maternal highest educational qualification, family’s financial situation. For children’s characteristics, age, gender and non-verbal fluid intelligence were included. The results indicate that time spent passively with digital devices (watching TV) is negatively related to a child’s ability to process verbal information. In contrast, the interactive time the child spent with Smart Screen Technologies is not significant and does not pose a threat to the development of phonological memory in preschool age. The study also showed that passive and active use of digital devices has no long-term impact on children’s phonological memory development progress over a year. The implications are that use of Smart Screen Technologies, which implies a higher degree of interactivity, is not associated with either short- or long-term negative effects on phonological memory development in preschool age, contrary to passive screen time exposure. The results can be applied in the elaboration of principles and programs on the use of digital devices for the entertainment and education of preschool children.

In modern pre-school education, more and more time is devoted to educational activities, while kindergarten children have very little time to play. However, play activity is extremely important for the development of inhibition in preschoolers. The article presents results of a study on the relationship between the child's acceptance of different roles (positive, wise or negative hero) and the success of executive function tasks implementation (cognitive flexibility and self-restraint). The study involved 81 children aged 5—6 years of Moscow kindergartens. Assessment of the level of executive functions development was carried out three times: pre-test (without a role), test (task execution in a role), post-test (without a role) using the same complex of methods. Based on the results of the pre-test, preschoolers were divided into 4 groups (3 experimental and one control). Ekvivalent groups formation was carried out basing on the actual level of executive functions development (low and high level) and on the number of boys and girls included in each of the groups. The study showed that the adoption of the role can have both positive and negative impacts on the success of executive function tasks implementation, depending on the type of task and the level of inhibition in preschoolers. The roles of the positive and wise characters had a positive effect in all three tasks, and the role of the negative character had of positive effect only in the tasks on behavioral and cognitive restraining control (in the task on cognitive flexibility it had a negative effect). In addition, role-taking in children with low levels of executive functions interfered with the behavioral control task, whereas in the cognitive control task, role-taking contributed to improved outcomes. Thus, accepting a role can help a preschooler to regulate their behavior, which confirms the role of play as the leading activity in preschool age.

Background. The phenomenon of multilingualism and its impact on child development are in the spotlight of latter-day psychology, and of utmost importance both for theory and practice. Language development is a strong predictor of psychological readiness for school and further academic success. At the same time, children’s mastery of written and oral speech in school education in a multilingual environment has several distinctive features. This study was dedicated to examining the influence of executive functions on the development of the vocabulary aspects of speech (both active and passive vocabulary) of mono- and bilingual children growing up in a bilingual environment. Objective. We aimed to analyze the relationship between bilingualism and language development (vocabulary and verbal fluency) and determine which executive functions may help overcome the resulting difficulties at preschool age. Design. Both monolingual and bilingual children participated in the study (n=137 and n=81, respectively). The children’s ages ranged from 6 to 7 years (M=78.7 months, SD=5.87). Two independent General Linear Models (GLM) were built to define which executive functions influenced the vocabulary and verbal fluency of the mono- and bilingual subjects (controlling for age, gender, and non-verbal intelligence as well). Results. The results confirmed that bilingualism is negatively related to language development, but showed that verbal working memory significantly helps bilinguals compensate for difficulties in developing vocabulary and verbal fluency. Conclusion. The study demonstrated that the ability to preserve and reproduce verbal information was of more significance for children’s vocabulary and verbal fluency than their language group (mono- or bilingual).
