This study was done with an fMRI and the Word Memory Test (WMT).
The WMT was given to ten subjects while they underwent fMRI.
The results for the full-effort trial supported earlier findings that there were activation peaks in the dorsolateral prefrontal cortex, superior parietal lobe, anterior cingulate, bilateral lingual cortices and anterior insula/frontal operculum
This research design was conducted to investigate the validity of:
the Coin in the Hand Test (CIH)
Autobiographical Memory Index (AMI)
Rey 15-Item Test (RIT)
Wechsler Mental Control Test (MCT)
There were three groups of participants, patients with an acquired brain injury, and two groups of control one stimulating a head injury and one that was to do their best.
The CIH and the MCT had good validity and showed high sensitivity and specificity when detecting malingering while the RIT and the AMI did a poor job of distinguishing the control groups and the brain injury group.
More research needs to be done on malingering and the test that are used to detect it.
A good question for further research would be what tests together have the best validity in detecting malingering.
Another question would be whether or not suspected malingerers should go through an fMRI.
These are important research questions because there are so many different tests out there that can aid in the detection of malingering and the use of multiple tests seem to work best for the detection.
With the use of an fMRI it is important to the research being done to see whether or not having a suspected malingerer go through an fMRI along with tests to detect malingering would make the diagnosis more solid.
