This experiment examined the impact of public self-consciousness and acting
ability on processes and stereotypical responses during deception. Seventy
-three nursing students were videotaped while (a) telling the truth and (b)
lying about a theft they had observed. A variety of cues were coded, inclu
ding criteria-based content analysis (CBCA) and reality monitoring (RM) in
which high scores indicated honest responding Compared with truth tellers,
liars waited longer before giving an answer spoke faster, made more speech
hesitations, showed fewer illustrators, and showed lower CBCA and RM scores
. Public self-consciousness was positively correlated with trying to contro
l behavior but negatively correlated with RM scores. Ability to act was neg
atively correlated with RM scores, with showing stereotypical deceptive fac
ial behavior (gaze aversion and smiling), with having to think hard while l
ying, and with being nervous while lying.
