Abstract: Subsequent to the publication in 1973 of the Manual on Terminology and Classification in Mental Retardation and the 1977 revisions, investigators have failed to adhere to the revisions. Additionally, some have failed to provide descriptive characteristics of subjects that would permit replication. Implications of these issues were discussed.
