AI Article Synopsis
- The Concealed Information Test (CIT) is designed to detect hidden knowledge about crimes based on physiological responses.
- A new version of the CIT uses a moving dot on a map to see how participants react when it passes different locations, measuring their breathing and skin conductance.
- The study found that informed participants showed specific physiological changes when the dot passed the target location, suggesting this approach can help distinguish between those who know about the threat and those who don't, and potentially refine the areas that need investigation.
Article Abstract
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.
