Test of Memory Malingering

The Test of Memory Malingering (TOMM) is a 50-question visual memory recognition test that discriminates between true memory impairment and malingering, with two learning trials and an optional retention trial following a delay.[1] It was first published in 1996 and is intended for testing individuals ages 16 and older.

The test has been shown to have high levels of sensitivity and specificity, and is largely insensitive to depression and anxiety.[2]


Two learning trials are administered in which examinees are shown 50 line drawings for 3 seconds each. These drawings are typically shown from a booklet, although computer versions of the test are available.[3] Each trial is then followed by a forced-choice recognition trial, with feedback provided for every response.[4]

The final results are judged according to two cut-off scores: (1) below chance, or (2) criteria based on head injured and cognitively impaired clients. A score below the recommended cutoff score on Trial 2 or the Retention Trial, or exhibiting below chance performance on any trial is consistent with probable response bias, and would suggest feigning of neurocognitive dysfunction.[2]

Use with children[edit]

The TOMM has also been examined with pediatric samples. The research with this measure has supported the use of adult criteria for suboptimal effort with children as young as 5 years old with a variety of diagnoses including ADHD, autism, and fetal alcohol syndrome.[5]
