| Research Abstract |
The main results on research implementation / management are as follows.
(1) Expansion of a twins registry : Complete-address investigation of the twins of an area was conducted from the basic resident register focusing on mainly Kanagawa and Chiba Prefecture, the address list (registry) was expanded, and 9000 sets of data was obtained. Thereby the base for big twins research which covers the main areas of Tokyo and the adjoining prefecture was improved.
(2) Expansion and maintenance of a twin sample : it appealed for the participation to investigation based on the above-mentioned registry, about 500 sets of adolescence twins' new sample was newly obtained, and the number of twins subjects exceeded 800 sets. Moreover, data was collected also from the parents of the twins concerning a rearing and a societal attitude also from the parents who cooperated until now. Thereby, the research on the structure of the heredity about the transfer in a family of a rearing attitude or a societal attit

ude and environment was attained.
(3) Addition of data and collect ion : From the old sample, the new data of event related potential (ERP), working memory, response time, and an individualized intelligence test (WAIS) were obtained. Moreover, from the new sample, the data about the zygosity diagnosis and the various personalities in question paper, eating behavior, etc. came to hand reliable model search of hereditability and the structure of heredity and environment. Model fitting by structural equation modeling was performed for these analyses.
(4) Development of a brain-wave analysis program, an improvement of brain-waves measurement environment : development of the special brain-waves analysis program which suited the present measurement situation installed the shield room for exact brain-waves measurement. Although this was because it was obliged to move the place of a laboratory which performs brain-waves measurement for convenience' sake [unexpected], it will contribute to an improvement of experiment conditions as a result.
