This criterion, however, inevitably leads to a loss of sensitivity (i.e., more guilty suspects declared innocent). We explored whether the sensitivity of a CIT procedure could be increased by adding an independent measure that is based on an entirely different psychological mechanism. In two experiments, we explored whether the accuracy of a CIT procedure could be increased by adding Symptom Validity Testing (SVT), a relatively simple, forced-choice, self-report procedure that has previously been used to detect malingering in various contexts. Results of a feigned amnesia experiment but not from a mock crime experiment showed that a combination measure of both tests yielded better detection than either test alone.<\/p><\/blockquote>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>ScienceDaily reports on an article published in the journal Psychophysiology describing a technique adapted by Maastricht University doctoral student Ewout Meijer and others for use in combination with polygraph-based concealed knowledge testing.
