THE USE OF INDIRECT MEMORY TESTS TO ASSESS MALINGERED AMNESIA - A STUDY OF METAMEMORY

Many techniques have been suggested for identifying criminal suspects who are simulating amnesia for the events surrounding a crime. The present research focuses on indirect memory tests as a potential means of discriminating between those who genuinely suffer from amnesia and those who are simulating. Subjects studied a list of words and subsequently performed either a word completion or a fragment completion task. Under normal indirect test instructions, typical priming effects were observed. When subjects were motivated to simulate amnesia for the list, target completion rates were consistently, and sometimes reliably, below baseline completion rates. This finding is contrary to the performance of genuine amnesics, whose performance on indirect tests typically mirrors that of normal subjects. Indirect tests may prove useful in discriminating genuine and simulating amnesics.
