This study considers the replies to a 14-item questionnaire, by 27 monozygotic (MZ) and 38 dizygotic (DZ) pairs. Another sample consisting of 48 sets of parents of twins (24 of whom were MZ and 24 DZ, not necessarily corresponding to the couples of twins actually studied) was used, to answer a questionnaire directly related the one put to the twin pairs. The results of statistical tests performed (canonical correlation and Fisher's discriminant) indicate that only in MZ twins does self-awareness outweigh pair-awareness. This does not seem to be related to any difference between MZ and DZ twins in the education/upbringing received from their parents.
本研究考量了27对同卵双胞胎（MZ）和38对异卵双胞胎（DZ）对一份包含14个条目的问卷的回答。另外还使用了一个由48对双胞胎的父母组成的样本（其中24对是同卵双胞胎的父母，24对是异卵双胞胎的父母，不一定与实际研究的双胞胎夫妇相对应），来回答一份与向双胞胎提出的问卷直接相关的问卷。所进行的统计检验（典型相关分析和费舍尔判别分析）结果表明，只有在同卵双胞胎中，自我意识才超过对伴侣的意识。这似乎与同卵双胞胎和异卵双胞胎从父母那里得到的教育/养育方式的任何差异无关。
