N1 - Funding Information:
The Keio Twin Project (KTP) was established in 1998, funded by the Grant-In-Aid Science Research of the Ministry of Education, Culture, Sports, Science and Technology and the Human Frontier Science Program to conduct behavioral genetic studies in a classic twin design for various kinds of human psychological traits in adolescence and young adulthood. This project mainly targets the source of normal variations in human behavioral characteristics in a general population. The variables contain comprehensive human behavioral and psychological traits: personality, psychiatry, mental health, sociality, cognition, physical traits, and so on. Recently, a new perspective involving evolutionary psychological research questions has been added to our behavioral genetic studies, which attempts to integrate genetics as applied to the adapta- tion of the human species, macrogenetics, to genetics focusing on individual differences in behavior, micro-genetics.

N2 - Since established in 1998, the Keio Twin Project (KTP) has been dedicated to investigating genetic and environmental sources contributing to human psychological traits in adolescence and young adulthood. A population-based twin registry was constructed by the KTP through the use of official residential records in the Tokyo area, and to date requests to participate in our research have generated 1040 pairs of twins and triplets of age 14 to 30, forming one of the largest twin registries in Asia. Our comprehensive datasets, obtained through questionnaires, performance tests, and physical measurements, cover a wide range of human traits: personality, psychiatry, mental health, sociality, cognition, and physical index. Demographic variables and environment of upbringing are also sought by twins and by some parents. This extensive information allows us to clarify the genetic and environmental overlap across multiple traits as well as specificities unique to single traits. Adding an evolutionary psychology perspective to the behavior genetics framework is currently being attempted in order to develop a grand theory of human genetics.
