Improving accuracy of veracity judgment through cue training.

The ability to make judgments of veracity was investigated to see if training individuals on visual, vocal, or verbal content cues of deception would increase their ability to judge whether a message was truthful. The overall rate of accuracy of judging veracity was significantly greater for subjects trained on verbal content cues. More specifically, for detecting truthful messages, subjects trained on verbal content cues had significantly greater accuracy than subjects who received no cue training, whereas for detecting deceptive messages, there were no significant differences in accuracy among conditions.
