Neuropsychological Clusters Within Intelligence Levels for Learning Disabled Children

Abstract

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.
