Outline of Final Research Achievements

Research results of this study were published in several research paper on twin language phenomenan.In sociability, the rate of percentile rank under 30 was highest in Dz femail(61.9%) and lowest in MZ mails(49.2). in home adaptation, the rate of percentile rank under 30 was highest inDz mails(55.0%), and lowest in Mz femails(38.2%). In school adaptation, the rate of percentile rank under 30 was highest in DZ oposite-sex pairs(48.1%), and lowest in MZ males(34.4%).In the score of social competence, the correlation coefficient was 0.817, for MZ pairs and 0.549 for Dz pairs in sociability, 0.659 for MZ pairas and 0.550 for Dz pairs, suggesting a possible genetic basis for this trait.
