In order to examine the genetic variance and heritability of temperament among Chinese infants in Taiwan, a total of 62 pairs of same-sexed twin infants given birth in four major general teaching hospitals in Taipei City were studied. Based on placentation and 12 red blood cell antigens, 44 MZ and 18 DZ pairs were identified. Temperament was assessed at the age of six months by the Chinese edition of Carey's Temperament scale. Significant genetic variance was observed for activity level, approach or withdrawal, intensity of reaction, quality of mood, and threshold of responsiveness, with a heritability of 0.64, 0.56, 0.74, 0.39, and 0.45, respectively. There was no significant intrapair difference in temperamental characteristics between monochorionic and dichorionic MZ twins.
为了研究中国台湾地区婴儿气质的遗传方差和遗传力，对台北市四家主要综合教学医院出生的62对同性双胞胎婴儿进行了研究。根据胎盘形成和12种红细胞抗原，确定了44对同卵双胞胎和18对异卵双胞胎。在六个月大时，使用中文版的凯里气质量表对气质进行评估。观察到活动水平、趋近或退缩、反应强度、情绪质量和反应阈存在显著的遗传方差，遗传力分别为0.64、0.56、0.74、0.39和0.45。单绒毛膜和双绒毛膜同卵双胞胎在气质特征上没有显著的配对内差异。
