Effort testing; Malingering; TOMM


The Test of Memory Malingering (TOMM; Tombaugh 1996) is a well-validated effort test that is commonly used by neuropsychologists (Sharland and Gfeller 2007). The TOMM employs a forced-choice recognition paradigm using 50 black target stimulus items (line drawings). During the study phase, the subject is shown each drawing for 3 s. After presenting the 50 items, each drawing is presented along with a distracter drawing. The subject is asked to choose the drawing that was shown during the study phase. The 50 line drawings are then shown a second time (i.e., “Trial 2”), followed by another test phase in which they are paired with 50 distracter drawings. After approximately 15 min, a retention test is given in which the original 50 items are paired with distracters. Thus, the test comprises three components: Trial 1, Trial 2, and Retention. The Retention trial is considered optional if the examinee passes Trial 2 (raw score > 44).
