This is a follow-up study aiming to describe personality development of twins and possible differences at different ages. The investigation was conducted at the Mother Clinic in the Karolinska Hospital in Stockholm. This report describes the language development of 35 twin pairs at 9 months of age. The development values show that no greater differences exist for girls between twins and singletons. The language result is however lower. The boys, on the other hand, have considerably lower results both on total development scale and on the language scale.
这是一项追踪研究，旨在描述双胞胎的性格发展以及不同年龄段可能存在的差异。该调查在斯德哥尔摩卡罗林斯卡医院的母婴诊所进行。本报告描述了35对双胞胎在9个月大时的语言发展情况。发展数值表明，双胞胎女孩与单胞胎女孩之间不存在更大差异。然而，语言发展结果较低。另一方面，男孩在总体发展量表和语言量表上的结果都要低得多。
