Abstract
100 disability claimants of the Social Security Administration referred for neuropsychological evaluation and 40 undergraduate college students asked to simulate brain damage were administered a measure for the detection of malingering, an abbreviated version of the Hiscock Forced-choice Procedure, and other neuropsychological tests. Half of each group was administered the Hiscock Procedure at the beginning of the battery; the other half was administered this test last. For both groups, the results indicated poorer performance on the earlier administration of the abbreviated Hiscock Forced-choice Procedure. Formal measures for detection of malingering should be an integral and early part of any neuropsychological evaluation in which the subject has a financial incentive to perform poorly.
