In this 2 (cue type) x 2 (statement type) two-way within-subject ANOVA design study, investigators look at the differences in average accuracy in determining whether a statement is a truth or a lie. Participants, college students, and professors from South Dakota State University, were assessed in their ability to detect deception. The participants had to determine whether a statement was a truth or a lie based on the actor’s verbal or nonverbal cues, each presented independently. The results suggest no significant effect of cue type (verbal or nonverbal) or statement type (truthful or deceitful) with participants’ accuracy being no better than guessing rate.
