本文旨在测试手指认知对学龄儿童后来的数字能力的预测能力的特异性，并有助于理解这种效应。一年级开始时，对 41 名儿童进行了手指认知、左右方向（格斯特曼“综合症”的另一个标志）和整体发展方面的测试。15 岁之后，对数字和阅读能力进行了评估。结果分析表明，与认知发展的一般指标相反，手指认知能力的表现可以很好地预测一年后的数字技能，但不能预测阅读技能，这证明了该预测因子的特异性。对于左右方向也得出同样的结论。然而，手指认知同样可以预测严重依赖或不严重依赖手指表示或幅度表示的数值任务的表现。结果根据本地化假设和功能假设进行了讨论。
This paper aimed to test the specificity of predicting power of finger gnosia on later numerical abilities in school-age children and to contribute to the understanding of this effect Forty-one children were tested in the beginning of Grade 1 on finger gnosia, left-right orientation (another sign of the Gerstmann "syndrome"), and global development Fifteen mouths later, numerical and reading abilities were assessed. Analyses of the results indicated that, contrary to the general measures of cognitive development, performance in the finger gnosia lest was a good predictor of numerical skills 1 year later but not of reading skills, which proves the specificity of that predictor. The same conclusion was also true for the left-right orientation. However, finger gnosia could equally predict performance in numerical tasks that do or do not rely heavily on finger representation or on magnitude representation. Results are discussed in terms of the localizationist and the functional hypotheses.
