Demographic characteristics and mean profiles of Learning Disability Index subsets of the standardization sample of the Wechsler Intelligence Scale for Children-Revised.

The Learning Disability Index (LDI) was validated by an examination of the mean profiles and demographic characteristics of high and low LDI subsets of the standardization sample of the Wechsler Intelligence Scale for Children-Revised. The LDI continuum, however, was found to measure Third Factor strengths/weaknesses as much as verbal-performance discrepancies.

Distribution of relative attention deficits on the WISC-R by age, sex, social class, and region.

We examined the demographic distribution of 102 subjects with attention deficits in the Wechsler Intelligence Scale for Children-Revised (WISC-R) (Wechsler, 1974) standardization sample. Neither age nor occupational status was significant; males were overrepresented (3:1); and the West was overrepresented by 50%, largely due to the relatively high proportion of females in the West who appeared within the attention deficit sample (41% in West vs. 19% in the rest of the nation). Replication is encouraged.

Stimulant medication and the hyperactive adolescent: myths and facts.

There is a widespread myth that when hyperactive or attentionally disabled youth reach puberty, stimulant medication ceases to be an effective and appropriate means of treatment. Since there is no scientific data to support this myth, its origin and maintenance are attributed to nonrational beliefs about stimulant medication, hyperactivity, and adolescence, as well as to methodological factors which have hampered accurate data-gathering by professionals.
