Event-related potential (ERP) methods for identifying malingering of cognitive deficit assume that elements of brain/cognitive functioning are not under a person's direct control, whereas neuropsychological methods assume that malingered cognitive deficit will present differently than true impairment in terms of level or pattern of errors on tests of cognitive function. Two studies were conducted to examine the combined use of neuropsychological and ERP methods for identifying malingering because of the potential independence of these approaches. All normal control participants performing at their best level (n = 25) were correctly classified by both ERP and neuropsychological methods. All participants simulating cognitive deficit (n = 35) were correctly classified on the basis of a positive outcome on either the neuropsychological or the ERP method. Results suggest that the neuropsychological and psychophysiological measures of malingering that were studied contribute non-redundant information in the classification of simulators.
用于识别认知缺陷伪装的事件相关电位(ERP)方法假定大脑/认知功能的要素不在人的直接控制之下,而神经心理学方法假定伪装的认知缺陷在认知功能测试中的错误水平或模式方面与真正的损伤表现不同。由于这些方法可能具有独立性,因此进行了两项研究以检验神经心理学和ERP方法在识别伪装方面的联合使用。所有表现最佳水平的正常对照参与者(n = 25)通过ERP和神经心理学方法均被正确分类。所有模拟认知缺陷的参与者(n = 35)根据神经心理学或ERP方法的阳性结果被正确分类。结果表明,所研究的伪装的神经心理学和心理生理学测量方法在模拟器分类中提供了非冗余信息。
