A Comparison of Three Tests to Detect Feigned Amnesia: The Effects of Feedback and the Measurement of Response Latency

Abstract

Three experiments provided validation data for an English language version of the Amsterdam Short Term Memory Test (ASTM test) developed to detect feigned memory impairment. Using a simulation design, the ASTM test compared favourably with the Test of Memory Malingering (TOMM) and appeared better than a newly-devised Digit Recognition Test (DRT). Feedback on the correctness of responses had no significant effect on performance but notable trends were apparent. Simulators were significantly slower than controls on computerised versions of the ASTM test and the TOMM. Convergent findings indicate that the English language version of the ASTM test may be useful in detecting malingering.
