The use of physiological tools to detect incidentally acquired concealed knowledge about crime-related information has been a controversial and well-researched topic among scholars for well over 100 years. This chapter focuses on potential legal hurdles for courtroom use of concealed information tests, including admissibility issues and constitutional issues under the Fourth and Fifth Amendments to the US Constitution.

Functional magnetic resonance imaging (fMRI) studies have documented differences between deceptive and honest responses. Capitalizing on this research, companies marketing fMRI-based lie detection services have been founded, generating methodological and ethical concerns in scientific and legal communities. Critically, no fMRI study has examined directly the effect of countermeasures, methods used by prevaricators to defeat deception detection procedures. An fMRI study was conducted to fill this research gap using a concealed information paradigm in which participants were trained to use countermeasures. Robust group fMRI differences between deceptive and honest responses were found without, but not with countermeasures. Furthermore, in single participants, …

The Concealed Information Test (CIT) is a credibility assessment protocol of an entirely different nature than the traditional lie detector test. Instead of attempting to detect actual lying (the goal of the commonly used Control Question Test), the goal of the CIT is to determine whether an individual possesses knowledge of specific details of a crime or event. For example, if a murder was committed at 800 Church Avenue using a .38 caliber revolver, the CIT seeks to determine whether a suspect recognizes the address and type of weapon.
The CIT presents subjects with various stimuli, one of which is …
