The study found that nonbraindamaged college subjects could not simulate organicity on the Bender-Gestalt test when instructed to do so. Although Pascal-Suttell and Canter scoring methods failed to differentiate malingerers from an organic criterion group, an ABPP clinician sorted 89% of the records correctly in a pilot study. Differentiating criteria were then spelled out from the pilot study protocols. In the main study the expert clinician correctly identified all 20 malingerers. Subsequent studies of intra- and inter-rater reliability produced satisfactory results.
