Abstract. Despite the importance of detecting feigned cognitive impairment, we have a limited understanding of the theoretical foundation of the phenomenon and the factors that affect it. Studies regarding the formation and implementation of feigning strategies during neuropsychological assessments are numbered, though there are indications that they tax cognitive resources. The current study assessed the effect of cognitive load manipulation on feigning strategies. To achieve this aim, we utilized a 2 × 2 experimental design; condition (simulators/honest responders) and cognitive load (load/no load) were manipulated while participants ( N = 154) performed a well-established performance validity test (PVT). The cognitive load manipulation reduced the quantity of feigning strategies, while also affecting their composition (i.e., strategies tended to be more intuitive). This suggests that reduced cognitive resources among those feigning cognitive impairment may impact the use of in-vivo feigning strategies. These findings, though preliminary, will hopefully encourage further research that will uncover the cognitive factors involved in the utilization of feigning strategies in neuropsychological assessments.

强制选择识别记忆性能效度测试中认知负荷对策略利用的影响

摘要。尽管检测假装的认知障碍很重要，但我们对这一现象的理论基础和影响它的因素的理解有限。关于神经心理学评估过程中假装策略的形成和实施的研究数量不多，尽管有迹象表明它们会对认知资源造成负担。目前的研究评估了认知负荷操纵对假装策略的影响。为了实现这一目标，我们采用了 2 × 2 的实验设计；条件（模拟器/诚实响应者）和认知负荷（负荷/无负荷）被操纵，而参与者（N = 154）进行了完善的绩效有效性测试（PVT）。认知负荷操作减少了伪装策略的数量，同时也影响了它们的构成（即，策略往往更直观）。这表明假装认知障碍者的认知资源减少可能会影响体内假装策略的使用。这些发现虽然是初步的，但有望鼓励进一步的研究，以揭示在神经心理学评估中使用假装策略所涉及的认知因素。
