Objective: Research suggests that the Word Memory Test (WMT), Victoria Symptom Validity Test (VSVT), and Test of Memory Malingering (TOMM) differ in their susceptibility to reduced cognitive ability in yielding false positive errors. In recognition memory paradigms, dual task interference disrupts conscious recollection but spares familiarity-based recognition memory. The current study explored the impact of reduced conscious recollection via dual task interference on the WMT, VSVT, and TOMM. Method: One-hundred-and-twenty-six non-clinical examinees were administered the WMT, VSVT, and TOMM. Examinees completed these tests under conditions of no dual task interference, dual task interference during study, and dual task interference during study and test. Results: Dual task interference impacted the WMT, FT = 86.74, p < .05, VSVT, FT = 72.23, p < .05, and TOMM, FT = 9.85, p < .05. Failure rates did not differ in the no interference condition (all 2.3%). More examinees failed the WMT than the TOMM in the interference during study condition, χ2 (1, N = 42) = 6.75, p < .05. In the interference during study and test condition, there was a significant effect of test, Q (2) = 12.10, p < .05; post-hoc tests revealed that the WMT yielded more failures than the TOMM, χ2 (1, N = 42) = 11.08, p < .05 After implementing the genuine memory impairment profile for the WMT, the failure rate of the WMT no longer differed from the TOMM or VSVT, Q (2) = 3.52, p = .17. Conclusion: The WMT, VSVT, and TOMM were all susceptible to dual task interference, with the WMT being the most susceptible and the TOMM the least. This indicates that adequate conscious recollection is required to successfully complete these tests.
