The Genetic Foundations of Attitude Formation: The Case of Left-Right Political Orientations
Kandler C, Bell E, Shikishima C, Yamagata S, Riemann R. The Genetic Foundations of Attitude Formation: The Case of Left-Right Political Orientations. In: R. A. S, S. M. K, eds. Emerging Trends in the Social and Behavioral Sciences: Interdisciplinary Directions. In Press.Since the pioneering work of Eaves and Eysenck (1974) appeared in Nature some 40 years ago,psychologists, sociologists, political scientists, and behavioral geneticists have investigated the effects of nature and nurture on the formation of social attitudes. It has consistently been found that manifestations of social attitudes (i.e., preferences, values, and beliefs pertaining to things like politics, religion, the treatment of ingroups and outgroups, etc.) are genetically influenced. More recently, researchers have focused their efforts on the psycho-physiological pathways between gene activity and attitudes. In particular, a broad body of research examines how personality traits may be a link between genetic factors and political orientations. The latter are typically treated as either a single left-right dimension or divided into two core aspects: resistance
to change/authoritarian conservatism and acceptance of inequality/social dominance orientation. In this article, we provide an overview of this research, present some findings from our recent international behavioral genetic study on the topic, and identify key issues for future research. We suggest that future studies treat attitude formation as a complex process in which genetic factors
and the psycho-physiological phenomena that stem from them are affected by the surrounding social environment and culture. Such research will require: (1) international study designs capturing individual and cultural levels of variation; and: (2) interdisciplinary collaboration among
scientists and researchers in various fields of study such as genetics, psychology, sociology, political science, neuroscience, and human biology

Psychosocial twin cohort studies in Japan: the Keio Twin Research Center (KoTReC)
The Keio Twin Research Center (KoTReC) was established in 2009 at Keio University to combine two longitudinal cohort projects — the Keio Twin Study (KTS) for adolescence and adulthood and the Tokyo Twin Cohort Project (ToTCoP) for infancy and childhood. KoTReC also conducted a two-time panel study of self-control and psychopathology in twin adolescence in 2012 and 2013 and three independent anonymous cross-sectional twin surveys (ToTcross) before 2012 — the ToTCross, the Junior and Senior High School Survey and the High School Survey. This article introduces the recent research designs of KoTReC and its publications
Cross-national differences in socioeconomic achievement inequality in early primary school : the role of parental education and income in six countries
This paper presents comparative information on the socioeconomic status (SES) gradients in literacy skills at age 6-8, drawing on harmonized national datasets from France, Germany, Japan, the Netherlands, the United Kingdom, and the United States. We investigate whether understanding of comparative SES gradients in early-to-mid childhood depends on the operationalization of SES (parental education, income, or both); and whether differences in inequalities at the end of lower secondary schooling documented in international large-scale assessments are already present when children have experienced at most two years of formal compulsory schooling. We find marked differences in the SES gradient in early achievement across countries that are largely insensitive to the way SES is measured, and that seem to mirror inequalities reported for older students. We conclude that country context shapes the link between parental SES and children’s educational achievement, with country differences rooted in the early childhood period
