The present study assessed 1142 learning disabled children with the Halstead Reitan Neuropsychological Battery and the Wechsler Intelligence Scale for Children-Revised. Subjects were divided into four groups based upon Full Scale IQ (i.e., 70-79; 80-89; 90-99 and 100-110). Subsequent clustering of the test data within each group suggested that while the students in the 70-79 IQ range were represented by a single Impaired Cluster, each of the other IQ groups had both an Impaired Cluster and a Non-Impaired Cluster.
本研究使用霍尔斯特德-雷坦神经心理成套测验和韦氏儿童智力量表修订版对1142名学习障碍儿童进行了评估。根据全量表智商将受试者分为四组（即70 - 79；80 - 89；90 - 99和100 - 110）。随后对每组内的测试数据进行聚类分析表明，智商在70 - 79范围内的学生仅由一个受损集群代表，而其他智商组均有一个受损集群和一个未受损集群。
