Do the visuomanual modality and the structure of the sequence of numbers in sign language have an impact on the development of counting and its use by deaf children? The sequence of number signs in Belgian French Sign Language follows a base-5 rule while the number sequence in oral French follows a base-10 rule. The accuracy and use of sequence number string were investigated in hearing children varying in age from 3 years 4 months to 5 years 8 months and in deaf children varying in age from 4 years to 6 years 2 months. Three tasks were used: abstract counting, object counting, and creation of sets of a given cardinality. Deaf children exhibited age-related lags in their knowledge of the number sequence; they made different errors from those of hearing children, reflecting the rule-bound nature of sign language. Remarkably, their performance in object counting and creating sets of given cardinality was similar to that of hearing children who had a longer sequence number string, indicating a better use of counting than predicted by their knowledge of the linguistic sequence of numbers.
视觉-手动模态以及手语中数字序列的结构是否会对失聪儿童计数能力的发展及其计数运用产生影响？比利时法语手语中的数字手势序列遵循五进制规则，而口语法语中的数字序列遵循十进制规则。研究人员对年龄在3岁4个月至5岁8个月之间的听力正常儿童以及年龄在4岁至6岁2个月之间的失聪儿童进行了数字序列准确性和运用情况的调查。研究采用了三项任务：抽象计数、物体计数以及创建具有给定基数的集合。失聪儿童在数字序列知识方面表现出与年龄相关的滞后；他们所犯的错误与听力正常儿童不同，这反映了手语的规则约束性。值得注意的是，他们在物体计数和创建具有给定基数的集合方面的表现与那些拥有更长数字序列的听力正常儿童相似，这表明他们在计数运用方面比根据其数字语言序列知识所预测的情况更好。
