Minimal Brain DysfunctionDifferences in Cognitive Organization in Two Groups of Index Cases and Their RelativesSandra M. Singer, PhD, recently completed postdoctoral studies in psychiatric genetics at the University of Iowa. Her research interests are primarily in the areas of cognitive development and developmental psychopathology. Requests for reprints should be addressed to Dr. Sandra M. Singer, Dept. of Psychology, Indiana State University, Evansville IN 47712.
Mark A. Stewart, MD, is the Ida P. Haller Professor of Child Psychiatry at the University of Iowa Hospitals and Clinics. He has written many articles on the genetics of hyperactivity, and has recently authored a handbook on psychological disorders of children.
Linda Puleski, MEd, is aflliated with the Child Development Clinic, University of Iowa Hospitals and Clinics. She is an evaluation specialist in the areas of special education and learning disabilities. The results of a comparative study of hyperactive and specific-reading-disabled children and their families are presented. The cognitive profiles of the two types of index cases reveal substantial differences. The data suggest that the learning problems frequently noted in hyperactive children are probably more similar to those found in a group which Yule (1972) calls "backward readers" than to those of the specific-reading-disabled children. Further differences between the two groups of index cases were noted in family background variables, such as familial incidence of psychopathology and criminal behavior, family history of hyperactivity, and family history of reading disability.
