Comparison of Bender Error and Time Scores for Groups of Epileptic,Retarded,and Behavior-Problem Children

Abstract

Bender error and time score comparisons were made between groups of 16 epileptic, 27 mentally retarded and 33 school and/or behavior problem children. The results indicated that there were significant differences in error scores between the epileptic and the school/behavior problem groups and between retarded and the school/behavior problem groups, but there were no significant differences in time scores for any groups. An attempt was made to assign children to their appropriate groups by using error or time scores alone; no single cut-off score was better than chance for accurately assigning group membership, however, a two-dimensional plot using both error and time scores was. The importance of this system for clinical diagnosis is discussed. Correlations between IQ, error and time scores and age are reported for each diagnostic group.
