A prior report found unusually high rates of performance validity test (PVT) failure in undergraduate research participants (31%-56%). The present study examined 110 undergraduate volunteers in three conditions (positive, neutral, or negative demand characteristics) in either an easy to hard or a hard to easy progression of neuropsychological tests using the Word Memory Test PVT. Neither demand characteristics nor test order had a substantial effect on test performance, and only a 6.4% failure rate was found on the PVT. These results suggest that neuropsychological testing experiments are completed faithfully by the vast majority of college undergraduates, although excluding the small number of participants failing PVTs would strengthen the internal validity of most studies.
先前的一份报告发现，本科研究参与者中表现效度测试（PVT）失败率异常高（31%-56%）。本研究使用单词记忆测试PVT，在三种条件（积极、中性或消极需求特征）下，对110名本科志愿者进行了从易到难或从难到易的神经心理学测试。需求特征和测试顺序对测试表现均无实质性影响，且PVT的失败率仅为6.4%。这些结果表明，绝大多数大学生能如实完成神经心理学测试实验，不过排除少数PVT测试失败的参与者会增强大多数研究的内部效度。
