Deception in investigative interviewing in forensic examinations

In this symposium we examine deceptive behaviour in the context of investigative interviewing and clinical assessment from both a practical and a theoretical perspective. In case of investigative interviewing, one presentation assesses the diagnostic validity of the comparable truth baseline technique to detect deception in single cases. Another presentation proposes four lying profiles that distinguish the types of lies people use based on personality traits, moral reasoning, and perceived cognitive load. We also examine deception in the context of clinical assessment for subjective and objective symptoms. One presentation assesses if examinees can recognize implausible items in self-reported validity tests for subjective symptoms. Finally, one presentation examines the use of brain waves to detect a specific but effective countermeasure in the forced choice test in case of feigned working memory problems.
