Abstract
The present study was an attempt to look at the empirical classification of children's learning disabilities based on neuropsychological variables at differing IQ levels. Subjects were divided into four groups based upon Full Scale IQ (i.e., 70-79, 8089, 90-99, 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 a moderately impaired cluster and a non-impaired cluster. The study attempted to respond to criticisms of previous research by using a large sample of subjects (N = 928), utilizing a broad range of subjects with a representative sample of abilities, and applying an interpretable structure to the cluster analysis (i.e., neuropsychological variables within IQ levels). The present research further offered a perspective on programming by way of neuropsychological functioning. As such, the results argued for placement procedures for learning disabled children that are apart from those formulas relative to achievement and intelligence.
