The authors describe male monozygotic twins, Jon and Jay, who are concordant for autism and hyperlexia. Autism and mental retardation were diagnosed at the age of 2 years 5 months. Jay was the more advanced twin in motor co-ordination, attention span and receptive abilities, but had frequent tantrums. When psychologically assessed at 7 years 2 months, Jon showed borderline/severe mental retardation on the measure of non-verbal intelligence and Jay was moderately retarded. Their receptive language age was greater than their expressive language age: Jon's speech was less mature but more communicative and Jay's was perseverative and ritualistic. Even though Jon was the more mentally retarded twin, Jay was the more autistic in some behavioral aspects. These twins highlight the relationship between autism and hyperlexia.
作者描述了同卵双胞胎男孩乔恩和杰伊，他们都患有自闭症和高词汇量症。他们在2岁5个月时被诊断出自闭症和智力迟钝。杰伊在运动协调、注意力持续时间和接受能力方面比乔恩更先进，但经常发脾气。在7岁2个月时进行心理评估时，乔恩在非语言智力测试中表现出临界/重度智力迟钝，杰伊则为中度智力迟钝。他们的接受性语言年龄大于表达性语言年龄：乔恩的语言不太成熟但更具交流性，而杰伊的语言则是重复和刻板的。尽管乔恩是智力更迟钝的双胞胎，但在某些行为方面杰伊更具自闭症特征。这些双胞胎凸显了自闭症和高词汇量症之间的关系。
