Detecting concealed information using brain-imaging technology.
Many conventional techniques for revealing concealed information have focused on detecting whether a person is responding truthfully to specific questions, typically using some form of lie detector. However, lie detection has faced a number of criticisms and it is still unclear to what degree conventional lie detectors can be used to reveal concealed knowledge in applied real-world settings. Here, we review the key problems with conventional lie-detection technology and critically discuss the potential of novel techniques that aim to directly read concealed mental states out of patterns of brain activity.
