3 segregated groups of Arab and Jewish deaf children of CA 10;9 (n = 28) were compared with a group of hearing Arab first graders (CA = 6;10, n = 32) on tests of basic arithmetic, static balance control, and the ability to suppress synkinetic finger movements. The hearing-impaired performed as well on arithmetic tasks and on the tests of synkinetic control as their normal peers who were four years younger, while on static balance they were even inferior to the latter. Significant correlations were found between the basic arithmetic and motor skills, within the hearing as well as within the hearing-impaired groups; these remained significant even within the small subgroups of the latter. As these results cannot be accounted for by low intelligence and neurological disturbances, or by direct or indirect effects of deficient language development, the assumption is supported that some type of neurological immaturity, unrelated to hearing loss, interferes with the acquisition of numerical skills in deaf children.
将三组年龄为10岁9个月的阿拉伯和犹太失聪儿童（n = 28）与一组听力正常的阿拉伯一年级学生（年龄 = 6岁10个月，n = 32）在基本算术、静态平衡控制以及抑制协同手指运动能力的测试上进行了比较。听力受损儿童在算术任务和协同控制测试中的表现与比他们小四岁的正常同龄人一样好，而在静态平衡方面他们甚至不如后者。在听力正常组以及听力受损组中，基本算术和运动技能之间都发现了显著相关性；即使在听力受损组的小子组中，这些相关性仍然显著。由于这些结果不能用低智商、神经紊乱，或语言发育缺陷的直接或间接影响来解释，因此支持这样一种假设，即某种与听力损失无关的神经不成熟类型会干扰失聪儿童数字技能的习得。
