Digit memory test; Hiscock malingering test


The Hiscock Forced-Choice Test (hereafter referred to as the Hiscock test) was described in a case report (Hiscock and Hiscock 1989). Although the authors subsequently referred to the test as the Digit Memory Test (DMT), it is commonly known as the Hiscock malingering test or simply the Hiscock test. The test has never been distributed as a commercial product, but the senior author has responded to requests for information about the test by sending instructions for constructing the stimuli, administering the test, and interpreting the results.

The Hiscock test comprises 72 stimulus cards, each of which contains a five-digit target. The target, which varies randomly from one card to the next, is presented for 5 s. After a variable delay, the patient is shown a response card containing two five-digit numbers, one of which is identical to the previous target. The other five-digit number on the response card (the foil) always...
