Validity of the Concealed Information Test in realistic mock crime scenarios: comment on Bradley, Malik, and Cullen.

Based on the low detection rates of participants who incidentally encoded crime-related details in a realistic mock crime scenario, Bradley, Malik and Cullen (2011) argued that laboratory studies overestimate the validity of the Concealed Information Test. Studies from our group using naturalistic mock crime scenarios, multiple physiological response measures and improved scoring and classification techniques suggest that such a general conclusion is not warranted.
