THE INCIDENCE OF BENDER-GESTALT FIGURE DEVIATIONS IN A GROUP OF MENTALLY RETARDED PSYCHIATRIC PATIENTS

Abstract

The Bender-Gestalt Test was given to thirty mentally-retarded psychiatric patients. The mean, standard deviation, and standard error were 56.73, 26.25, and 4.80 respectively. Rotation was the most frequent major deviation which occurred in all the designs.
Design # 7 was the most difficult one to be reproduced in the sample. This design by itself, was subject to 47% of distortion, 79% of omission, and 21% of rotation.
