The Concealed Information Test (CIT) aims to extract concealed crime-related knowledge using physiological measures. In the present study, we propose a new variant of the CIT that contains a continuously moving stimulus. A total of 81 participants were either informed or not about the specific location of an upcoming terrorist attack. The CIT consisted of a map with a superimposed moving dot, combined with measurements of respiration and electrodermal activity. The results revealed both respiratory suppression and an increase in skin conductance when the moving dot passed the target location only in informed participants. These findings showed that this new variant of the CIT can differentiate between groups of informed and uninformed individuals and an exploratory analysis revealed it can help narrow down a search area.
隐蔽信息测试（CIT）旨在通过生理测量手段提取与犯罪相关的隐蔽知识。在本研究中，我们提出了一种包含持续移动刺激的CIT新变体。共有81名参与者被告知或未被告知即将发生的恐怖袭击的具体地点。CIT由一张叠加有移动点的地图组成，并结合了呼吸和皮肤电活动测量。结果显示，只有在被告知的参与者中，当移动点经过目标位置时，会出现呼吸抑制和皮肤电导增加的情况。这些发现表明，这种CIT新变体能够区分被告知和未被告知的个体群体，一项探索性分析显示它有助于缩小搜索范围。
