Not all performance validity tests are created equal: The role of recollection and familiarity in the Test of Memory Malingering and Word Memory Test

ABSTRACTIntroduction: The Test of Memory Malingering (TOMM) and the Word Memory Test (WMT) are both performance validity tests (PVTs) that use a two-alternative forced-choice (2AFC) recognition memory format. Several studies have reported that these tests are susceptible to cognitive impairment and that the WMT is more susceptible than the TOMM. The current study explored components of recognition memory (i.e., conscious recollection and familiarity) underlying the TOMM and WMT to identify factors that make them susceptible and resilient to cognitive impairment. Method: Fifty-four nonclinical undergraduate research participants were administered the TOMM and WMT while providing introspective judgments about their recognition memory using the remember/know/guess procedure. In addition, half of participants were administered dual-task interference, a manipulation intended to reduce recollection, during these tests, while the other half completed these tests without interference. Standard cutoffs on the TOMM...
