Abstract
This study was designed to compare the copying and recall performances of the Bender-Gestalt of 80 psychiatric patients, falling into five diagnostic groups. To obtain a quantitative measure of the copying performance the Pascal and Suttell scoring system was utilized; however, lack of scoring items for design A and no really satisfactory recall scoring system led to a revised system which resulted in a significantly more discriminating system than Olin and Reznikoff's. Also the study yielded various quantitative and qualitative differences between the five diagnostic groups, the most significant being between the organic and the functional (schizophrenic, depressive, neurotic, and character disorder) sub-groups. Thus performance on the Bender, especially the quantitatively scored recall performance, can be used as a valid diagnostic instrument to differentiate organic from non-organic patients. Yet in each sub-group the various aspects of the Bender performance (copying score, recall score, and number of designs recalled) appeared to be interrelated, while the time element was found to be an independent factor which also did not help to differentiate the diagnostic groups. Performance on the various designs fell into a definite pattern, particularly on the recall phase.
