Fourteen (14) dyscalculic school children were drawn from a larger population of learning-disabled children. The subjects were divided into two groups, those with normal-or-better reading ability and those with dyslexia equal in degree to their dyscalculia. Both groups showed a variety of behavioral deficits in addition to those comprising Gerstmann's syndrome and were notably poor in auditory and visual discrimination and motor coordination. Good readers showed severely-impaired ability to make right-left discriminations, while the poor readers were average in this ability. Poor readers showed marked impairment of word fluency and hand writing, while good readers were average in this regard. The dyscalculia and reading deficits reported here appear unrelated to central-language impairment. Subjects with all four elements of the developmental Gerstmann's syndrome did not constitute an homogeneous behavioral group and were found among samples of both good and poor readers. The pattern of behavioral deficits shown by these subjects suggests cerebral impairment rather than slow maturation as a probable etiology. While the DGS is not useful as a behavioral description, its value as a possible localizing neurological sign cannot yet be ruled out.
14名计算障碍学童从大量学习障碍儿童群体中选取。这些受试者被分为两组，一组阅读能力正常或更好，另一组诵读困难程度与计算障碍程度相当。除了构成格斯特曼综合征的那些缺陷外，两组都表现出各种行为缺陷，在听觉和视觉辨别以及运动协调方面明显较差。阅读能力好的人在进行左右辨别时能力严重受损，而阅读能力差的人在这方面能力一般。阅读能力差的人在单词流畅性和书写方面有明显损伤，而阅读能力好的人在这方面表现一般。这里报告的计算障碍和阅读缺陷似乎与中枢语言损伤无关。具有发育性格斯特曼综合征所有四个要素的受试者并不构成一个行为同质群体，在阅读能力好和差的样本中都有发现。这些受试者表现出的行为缺陷模式表明，大脑损伤而非发育迟缓可能是病因。虽然发育性格斯特曼综合征作为一种行为描述并无用处，但其作为可能的神经定位体征的价值尚未排除。
