Abstract

The Wechsler Intelligence Scale for Children--Revised was administered to two independently identified samples of monozygotic (MZ) and dizygotic (DZ) twin children. Co-twins in the first sample were tested by the same examiner, while co-twins in the second sample were tested by different examiners. IQ intraclass correlations were similar for the two MZ twin samples (.84 and .88), and identical for the two DZ twin samples (.54). The implications of this analysis are discussed with reference to twin study methodology, research on IQ similarity and replication of child development research.

摘要

对两组独立确定的同卵（MZ）和异卵（DZ）双胞胎儿童样本进行了韦氏儿童智力量表修订版测试。第一个样本中的双胞胎由同一名考官测试，而第二个样本中的双胞胎由不同的考官测试。两个同卵双胞胎样本的智商组内相关性相似（分别为0.84和0.88），两个异卵双胞胎样本的智商组内相关性相同（为0.54）。结合双胞胎研究方法、智商相似性研究以及儿童发展研究的重复性，对该分析的意义进行了讨论。
