Calibration Methods of Deception Detection

A sample of judges with different ages (children, young adults and adults) as well as a sample of actors (young adults) was required to participate in a deception detection study. Judges were required to evaluate 16 videos where a person might be lying or not lying about a video content. The study sought to look over three aspects of judges’ accuracy judgments related to deception detection (discrimination, calibration and global error) by using calibration graphs. Results showed that some children outperformed adults by better estimating the probabilities of being deceived but they performed the same as both adult groups at discriminating those actors who lied from those who did not lie. It is argued that since children have not been sufficiently exposed to cultural factors related to deceiving behavior, they have better calibration judgment. Implications to detection deception research are discussed in the paper.
