Female deception detection as a function of commitment and self-awareness
Amanda K. Johnson, Allyson Barnacz, Paul Constantino, Jason Triano, Todd K. Shackelford and Julian Paul Keenan

It was been hypothesized that evolutionary factors including self-awareness and commitment are related to deception detection. In this study, 34 female undergraduates were tested for their ability to detect deception via a video paradigm. Females that were not in a committed relationship were significantly better at detecting males “faking good” as compared to committed females. Further, self-awareness was correlated with the ability to detect deception. These data are consistent with the hypothesis that deception may be related to self-awareness and that such a relationship is related to reproductive advantages secured by the ability to deceive.

Psychology graduate students research lie detection

Psychology graduate students research lie detection The Round Up 9 Sept 04

Two New Mexico State University graduate students have been looking for clues to detect dishonesty, which may help with law enforcement, and have proven the existence of a “lie bias.” In experiments, Gary Bond and Dan Malloy, doctoral students in psychology, analyzed conversations between prisoners for verbal cues of dishonesty.[…] They had prisoners watch videos, then recorded inmates’ conversations with each other about what they saw. Bond asked the participants to lie or to tell the truth about the videos, according to a statement from University Communications at NMSU. Malloy said that upon interviewing the prisoners about their conversations, the researchers found that people in the prison context have a lie bias. They were more likely to believe someone was lying to them than NMSU students were.

Police officers’ credibility judgments: Accuracy

Police officers’ credibility judgments: Accuracy and estimated ability
Eugenio Garrido, Jaume Masip, Carmen Herrero
International Journal of Psychology 39(4), August 2004

A study was conducted to examine Spanish police officers’ and nonofficers’lie- and truth-detection accuracy, as well as their estimated detection ability. The participants were 121 police officers and 146 undergraduates who watched videotaped truthful and deceptive statements. They had to indicate: (1) whether each statement was truthful or deceptive, and (2) how good police officers were, in comparison with the general population, at detecting the truthfulness or deceptiveness of a statement. Results indicate that police officers’ accuracy was not higher than that of nonofficers, rather, while the officers reached an accuracy rate close to chance probability, the undergraduates surpassed that probability. Officers had a very strong tendency to judge the statements as deceptive; this made them less accurate than the students in judging the truthful accounts, while both groups reached a similar accuracy when judging the deceptive ones. Both occupational samples considered that the police are more capable of identifying truths and lies than the general population. However, this belief was stronger among the officers themselves than among the nonofficers. No significant correlation between estimated ability and accuracy was found for either sample. The results are explained in terms of the participants’ wrong beliefs about the cues to deceit and the socialization process that police officers undergo, which would increase their confidence and perceived ability while hindering their learning of the actual indicators of deceit. The need for officers to receive training is emphasized, and some directions are given on how this training should be carried out.
