Very little is known about the autonomic psychophysiological responses while individuals are executing a Symptom Validity Test. Therefore, the aim of this study is to analyze the peripheral psychophysiological correlates (electrodermal conductance and heart rate) during the performance of the Victoria Symptom Validity Test (VSVT). The sample of this study was composed of 30 participants who underwent the VSVT under two conditions: Exaggeration of cognitive deficits (ECD) and normal effort. Our results showed differences on skin conductance between correct answers and errors limited to the decision-making phase of the ECD condition. Those differences found in the maximum conductance value when participants decide to simulate their deficits could be related to emotional activation. No differences were found on the variable heart rate between the two conditions of the study. Implications of these results are discussed.
关于个体在执行症状效度测试时的自主心理生理反应，我们知之甚少。因此，本研究的目的是分析在执行维多利亚症状效度测试（VSVT）时的外周心理生理相关性（皮肤电导率和心率）。本研究的样本由 30 名参与者组成，他们在两种条件下接受了 VSVT：认知缺陷夸大（ECD）和正常努力。我们的研究结果表明，在 ECD 条件的决策阶段，正确答案和错误答案之间的皮肤电导率存在差异。当参与者决定模拟自己的缺陷时，在最大电导率值上发现的这些差异可能与情绪激活有关。在研究的两种情况下，心率变量没有差异。讨论了这些结果的含义。
