Executive functions (EFs) and intelligence (IQ) are phenotypically correlated and heritable; however, they show variable genetic correlations in twin studies spanning childhood to middle age. We analyzed data from over 11,000 children (9-10-year-olds, including 749 twin pairs) in the Adolescent Brain Cognitive Development (ABCD) Study to examine the phenotypic and genetic relations between EFs and IQ in childhood. We identified two EF factors – Common EF and Updating-Specific, which were both related to IQ (rs = .64-.81). Common EF and IQ were heritable (53-67%), and their genetic correlation (rG = .86) was not significantly different than 1. These results suggest that EFs and IQ are phenotypically but not genetically separable in middle childhood.

The Bielefeld Longitudinal Study of Adult Twins (BiLSAT) is a German longitudinal study of monozygotic and dizygotic twins reared together, including more than 1,100 twin pairs aged between 14 and 80 who participated in the first wave. Data were collected at five waves of assessment between 1993 and 2009. Initially, the study focused on genetic and environmental influences on the structure and the development in adult temperament and personality. Today, the study includes a broad range of individual variables, such as personality disorders, major life goals, interests, attitudes, values, life and work satisfaction, and major life events. A special feature of this genetically informative study lies in the multiple-rater approach (i.e., self-reports and peer reports). Longitudinal multiple-rater analyses allow researchers to go beyond the basic nature–nurture decomposition of variance in self-reports examining genetic and environmental influences on stability and change in more accurately measured individual attributes. In the current article, we briefly describe the design and contents of BiLSAT as well as some recent major findings and future plans.

The article discusses the results of a study of the relationship between executive functions (inhibitory control, cognitive flexibility, working (speech and visual) memory and the development of Russian speech in children with natural bilingualism and monolinguals in older preschool age. The study involved 63 preschool children (50.8% - boys) aged from 5.6 to 7.3 years (M = 6.42, Med = 6.4) from preschool institutions of Izhevsk (Udmurt Republic). The sample included 31 children with natural bilingualism (Udmurt/Russian language) and 32 monolinguals (Russian language). Standardised methods in the Russian-language version were used to identify the executive functions: the method of verbal-colour interference of by J. Stroop (inhibitory control), the method of studying the learning ability by A.Y. Ivanova (cognitive flexibility) and the test tasks Speech Memory and Visual Memory (working memory). The level of speech development was measured using the test tasks Speech Antonyms, Speech Classifications and Arbitrary Mastery of Speech developed by L.А. Yasyukova. The following mathematical statistics methods were used: descriptive statistics, Mann - Whitney U-test and Spearman rank correlations. According to the results of the study, the facts of the advantages of bilingualism in older preschool age in executive functions, in particular, in inhibitory control cognitive flexibility and speech memory were confirmed. At the same time, no general patterns were determined in the development of Russian speech (L2) in connection with the development of the executive functions of bilingual children: this is explained by the individualisation of the processes of linking the components of speech activity in the second language and cognitive control. In monolingual preschoolers, the speech development in their native language (L1) is associated with the formation of higher mental (executive) functions and the development of the ability to control information processing.
