A formula for detecting faked Raven's Standard Progressive Matrices profiles was cross-validated on 46 experimental malingerers and 381 people from the standardization sample. The formula yielded a cross-validated 26% false-negative rate and a 5% false-positive rate.
A formula for detecting faked Raven's SPM profiles was cross-validated on 44 children and adolescents (ages 7-17). It yielded a false negative rate of 64%. However, a rule using three very easy items (i.e., any of A3, A4 or B1 missed) yielded a hit rate of 95%, with 5% false positive and negative rates. All but two of the participants were able to produce lower scores when asked to fake the test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
