Come to think of it...»: interrogative probes, deceptive communication, and deception detection

A study of deceptive communication in 3 phases. In (1) communicators (N = 45) responded truthfully or deceptively to positive or negative interrogative probes in video-taped interviews; in (2) the interviews were shown, at 4 levels of probe exposure, to observers (N = 139) who rated the communicators' veracity; & in (3) verbal & nonverbal cues were correlated with actual & perceived deception (N not specified). Although exposure level had no effect on detection accuracy, liars & truthtellers exposed to negative interrogative probes were judged more truthful than those exposed to positive probes. Analysis of the verbal & nonverbal cues revealed that tone of the nonverbal cues relied on as indicators of deception were related to actual deception, & only one of the verbal cues (verbal content) was related to actual message veracity. Implications of these findings & suggestions for future research are offered. 3 Tables, 1 Figure, 12 References. HA
