N2 - Performance validity tests (PVTs) aim to detect noncredible performance during neuropsychological testing. Despite their established utility, their cognitively undemanding nature and format may unintentionally reveal their purpose, leading to ongoing efforts to develop novel PVTs. In this study, we examined the ability of the embedded validity indices of the Poreh Nonverbal Memory Test (PNMT) to detect simulation. An initial sample of 61 participants was randomly assigned to either a simulation or control condition. Participants then completed the PNMT, the Test of Memory Malingering (TOMM), and the Digit Span subtest. A second validation study using 49 participants was conducted in Israel utilizing the same paradigm. In both studies, simulators were less accurate, exhibited shallow and– at times– reversed PNMT learning curves, and obtained lower scores on the delayed and recognition trials. Additionally, PNMT indices showed similar sensitivity and specificity and were highly correlated with more established validity measures. These findings, however, should be considered preliminary and await further validation in clinical settings.
