“…Some researchers have compared people simulating memory impairments with actual braininjured, amnesic patients. These studies reveal that people feigning amnesia often overplay their assumed impairment and perform worse on memory tests than do genuine amnesic patients (see, e.g., Greiffenstein, Baker, & Gola, 1994;Wiggins & Brandt, 1988). Other researchers have employed various diagnostic measures to differentiate genuine from feigned amnesia.…”

Defendants who are accused of serious crimes sometimes feign amnesia to evade criminal responsibility. Previous research has suggested that feigning amnesia might impair subsequent recall. In two experiments, participants read and heard a story about a central character, described as "you," who was responsible for the death of either a puppy (Experiment 1) or a friend (Experiment 2). On free and cued recall tests immediately after the story, participants who had feigned amnesia recalled less than did participants who had recalled accurately. One week later, when all participants recalled accurately, participants who had previously feigned amnesia still performed worse than did participants who had recalled accurately both times. However, the participants who had formerly feigned amnesia did not perform worse than did a control group who had received only the delayed recall tests. Our results suggest that a "feigned amnesia effect" may reflect nothing more than differential practice at recall. Feigning amnesia for a crime need not impair memory for that crime when a person later seeks to remember accurately.

“…But amnesia malingerers perform worse than amnestics in biographical questions as they suppose that amnestics do not remember even this. This discrepancy between empirical data and layman's knowledge differentiates malingerers from the genuinely impaired [Wiggins and Brandt, 1988]. Closely related is the gross exaggeration of disorders.…”

Neurobehavioral assessment is frequently made in a forensic context. The cognitive assessment may be biased due to an intentional manipulation of data by the patient motivated by attainment of compensation, that is, malingering. Although malingering is highly relevant in behavioral toxicology, the issue and its assessment are underrepresented in the literature. A routine assessment of malingering is important to reduce false‐positive and false‐negative errors in assessment, thereby establishing the credibility and validity of behavioral assessment. In the long run, the routine inclusion of malingering measurements might reduce claims and encourage employers to be more cooperative in behavioral toxicology studies. Guidelines for malingering assessment and research, inferred from the clinical and research literature, are discussed. Sensitivity to the problematic issues involved in assessing malingering behavior is an important step toward malingering detection in the clinical setting and to the establishment of assessment methods that are less confounded by these issues.

“…Using the WMS-R Figure Memory and Visual Reproduction I Subtests in a discriminant function, these tests "performed with an accuracy rate of 74% on cross-validation.., correctly classifying about three-quarters of the malingerers and three-quarters of the controls" (Bernard, 1990, p. 724). The author concluded that the WMS-R Figural Memory Subtest, along with two other recognition memory tests, support the utility of recognition tasks as sensitive to malingered memory impairment as had been noted previously by Wiggins and Brandt (1988).…”

Practical guidelines in the use of symptom validity and other psychological tests to measure malingering and symptom exaggeration in traumatic brain injury cases

The detection of malingering or symptom exaggeration has become an essential component in forensic neuropsychological evaluations, particularly in cases involving personal injury claims. Symptom Validity Tests refer to those measures that can be utilized to detect test performance that is so poor that it is below the level of probability, often times even among brain-damaged populations. This article outlines legal standards for expert testimony in regard to forensic neuropsychological personal injury evaluations. The article provides an outline of specific Symptom Validity Tests and Indicators, and reviews literature supporting test sensitivity and validity. In addition, the use of symptom checklists and questionnaires is discussed, as well as the appropriate use of Symptom Validity Tests and Indicators to establish the presence or absence of malingering or symptom exaggeration.
