Empirically Derived Learning Disability Subtypes: A Replication Attempt and Longitudinal Patterns over 15 Years.
Spreen, Otfried; Haaf, Robert G.
Journal of Learning Disabilities, v19 n3 p170-80 Mar 1986
Test scores of two groups of learning disabled children (N=63 and N=96) were submitted to cluster analysis in an attempt to replicate previously described subtypes. All three subtypes (visuo-perceptual, linguistic, and articulo-graphomotor types) were identified along with minimally and severely impaired subtypes. Similar clusters in the same population were found after a 15-year interval. (Author/CL)
