本研究探讨了数学学习障碍的指标是否观察到5-和6岁的儿童与神经纤维瘤病1型（NF 1）和5- 6岁的女孩与特纳综合征或脆性X综合征。将14名特纳综合征女孩、9名脆性X综合征女孩和11名NF 1儿童的数据与年龄、性别、智商评分和年级水平相匹配的对照参与者的数据进行比较。结果表明，与对照组相比，患有脆性X综合征或特纳综合征的女孩更有可能出现特定的数学困难，特纳综合征组表现出更大的效应量。NF 1幼儿有一个异质性的配置文件，没有具体的数学残疾的暗示。结果，讨论了他们的理解数学残疾亚型和数学困难的识别在早期学年的影响。
The present study examined whether indicators of math learning disability are observed in 5- and 6-year-olds with neurofibromatosis type 1 (NF1) and in 5- to 6-year-old girls with Turner syndrome or fragile X syndrome. Data from 14 girls with Turner syndrome, 9 girls with fragile X syndrome, and 11 children with NF1 were compared to data from control participants matched on age, sex, IQ score, and grade level. The results indicate that girls with fragile X syndrome or Turner syndrome are significantly more likely to have specific math difficulties relative to their control group, with a larger effect size demonstrated by the group with Turner syndrome. Young children with NF1 had a heterogeneous profile not suggestive of specific math disability. The results an, discussed in terms of their implications for understanding math disability subtypes and the identification of math difficulty in the early school years.
