数字集测试是为了评估儿童识别和处理阿拉伯数字和物体集所代表的数量的速度和准确性而开发的。该测试的效用预测数学成绩和数学学习障碍（MLD）的风险进行了评估，为223名儿童的样本。一年级数字集测试成绩的信号检测分析提供了儿童对数字的敏感性和反应偏差的措施。敏感性测量，d′，但不是反应偏差测量是预测三年级数学成绩，以上和超越智力，工作记忆，和一年级成绩的影响。进一步的分析评估了该测试的敏感性和特异性，并显示一级d′评分确定了三年级诊断为MLD的3名儿童中的2名，并正确确定了10名无MLD风险的儿童中的9名。
The Number Sets Test was developed to assess the speed and accuracy with which children can identify and process quantities represented by Arabic numerals and object sets. The utility of this test for predicting mathematics achievement and risk for mathematical learning disability (MLD) was assessed for a sample of 223 children. A signal detection analysis of first grade Number Sets Test scores provided measures of children’s sensitivity to number and their response bias. The sensitivity measure, d′, but not the response bias measure was predictive of third grade mathematics achievement scores, above and beyond the influence of intelligence, working memory, and first grade achievement scores. Further analyses assessed the sensitivity and specificity of the test and revealed that first grade d′ scores identified 2 out of 3 children diagnosed as MLD in third grade and correctly identified about 9 out of 10 children who were not at risk for MLD.
