Specialization of the right hemisphere for spatial processing was studied in 200 normal boys and girls between 6 and 13 years of age. Boys performed in a manner consistent with right hemisphere specialization as early as the age of 6. Girls showed evidence of bilateral representation until the age of 13. The results suggest a sexual dimorphism in the neural organization underlying cognition during a major period of childhood. The results, which have implications for reading instruction, are discussed in terms of a possible sex difference in neural plasticity during development and the clinical consequences of such a difference.
对200名6至13岁的正常男孩和女孩进行了研究，以探讨右半球在空间处理方面的专门化情况。男孩早在6岁时的表现就与右半球专门化一致。女孩直到13岁都表现出双侧表征的迹象。研究结果表明，在儿童成长的主要阶段，认知背后的神经组织存在性别差异。鉴于发育过程中神经可塑性可能存在的性别差异以及这种差异的临床后果，对这些具有阅读教学意义的结果进行了讨论。
