Lying words: predicting deception from linguistic styles.

Telling lies often requires creating a story about an experience or attitude that does not exist. As a result, false stories may be qualitatively different from true stories. The current project investigated the features of linguistic style that distinguish between true and false stories. In an analysis of five independent samples, a computer-based text analysis program correctly classified liars and truth-tellers at a rate of 67% when the topic was constant and a rate of 61% overall. Compared to truth-tellers, liars showed lower cognitive complexity, used fewer self-references and other-references, and used more negative emotion words.

Measuring deception: test-retest reliability of physicians' self-reported manipulation of reimbursement rules for patients.

This study examined the test-retest reliability of physicians' self-reported manipulation of reimbursement rules for patients. The test-retest reliability of self-report of three specific tactics were examined: (1) exaggerating the severity of patients' conditions, (2) changing a patient's official (billing) diagnosis, and (3) reporting signs or symptoms that patients did not have. The reliability of a scaled summary measure of physicians' manipulation of reimbursement rules was also assessed. Overall, the authors found high levels of test-retest agreement across all three items and the summary measure. These findings suggest that self-report can be used to produce reliable data on this controversial issue. Specifically, the three items reported here can be used to produce a reliable summary measure of physicians' manipulation of reimbursement rules to help patients obtain care that physicians perceive as necessary.

Repeated questions, deception, and children's true and false reports of body touch.

Four- to 7-year-olds' ability to answer repeated questions about body touch either honestly or dishonestly was examined. Children experienced a play event, during which one third of the children were touched innocuously. Two weeks later, they returned for a memory interview. Some children who had not been touched were instructed to lie during the interview and say that they had been touched. Children so instructed were consistent in maintaining the lie but performed poorly when answering repeated questions unrelated to the lie. Children who were not touched and told the truth were accurate when answering repeated questions. Of note, children who had been touched and told the truth were the most inconsistent. Results call into question the common assumption that consistency is a useful indicator of veracity in children's eyewitness accounts.

Detection of conscious deception using the Child Abuse Potential Inventory lie scale.

Two studies were conducted to provide data on the construct validity of the Child Abuse Potential Inventory lie scale. In Study One, 187 male and female undergraduate students were administered either the Child Abuse Potential Inventory, the Marlowe-Crowne Social Desirability Scale, or the Unlikely Virtues Scale. Three instructional sets were provided: respond honestly, distort responses in a positive manner, and distort responses in a negative manner. Each scale successfully discriminated between subjects in the honest and faking good conditions. Only the Marlowe-Crowne scale discriminated subjects in the faking bad condition through their low scores. No gender differences were observed as a function of instructional set or test employed. In Study Two, 31 male and female parents were given the CAP-Inventory under the same instructional sets provided in Study One. The findings for the parent group, the population the CAP-Inventory was designed to be employed with, replicated the results found in Study One.

Use of false ID cards and other deceptive methods to purchase alcoholic beverages during high school.

Altered motor vehicle drivers's licenses or other falsified or counterfeit photo identification cards are widely and illegally used by teenagers to obtain beer and other alcohol beverages. We obtained information on the methods currently used by teenagers to purchase beer and wine by asking nine hundred teenagers, between 16-19 years old to complete a brief, confidential questionnaire. High school students most often obtained alcoholic beverages by requesting someone of legal age to purchase it for them. College students used borrowed, altered, or counterfeit identification (ID) more often than high school students. Photo IDs purchased through mail order from a magazine advertisement were used infrequently and when use was attempted, they were sometimes (25%) unsuccessful. Fifteen percent of high school students, 14% of college freshmen, and 24% of teenage drug abusers were able to purchase beer by the case with borrowed, altered, or fake ID. Suggestions to reduce sales of alcohol-containing beverages to minors include universal "carding" of prospective purchasers, use of two view or hologram photos on a drivers' license, requiring three different ID cards at the point of purchase, and penalties to stores that fail to make a good effort to identify underage customers.

[Fatal deception: the tobacco industry's "new" world standards for tobacco marketing].

Being increasingly threatened by the worldwide antismoking struggle, the major tobacco companies are eager to improve their public image. This leads the companies to adopt inconsequential "measures" such as the tobacco industry's "new" standards for tobacco marketing that were "voluntarily" issued in September 2001 by the British American Tobacco company. These measures are clearly attempts to reduce the disapproval generated by the companies' promotion and advertising campaigns, which indirectly target young people. With these standards the tobacco companies supposedly commit themselves, among other things, to not using advertising directed at youth and to not selling or distributing tobacco products in places frequented by young people. This document explains why these measures are completely ineffective, are not anything new, and are a subtle effort to feign a conscientious, responsible attitude, which is far from genuine. As long as there are marketing activities directed at adults, young people will be exposed to the influence of those activities. Many countries have completely prohibited the marketing of tobacco products, given that the "new" marketing standards do not represent progress in any way whatsoever.

Deception and perceived exertion during high-intensity running bouts.

This investigation examined the overall and localized perceived exertion responses to repeated bouts of submaximal, high-intensity running when subjects were deceived. Well-trained male and female n = 40) runners were randomly assigned to four groups who completed three 1680-m bouts of running at 80-86% peak treadmill running speed. The two experimental groups, Expected Similar and Expected Increase, were deceived of the actual run intensities while the two control groups, Control Increase and Control Similar, were informed of the actual protocol. After each run, ratings of perceived exertion (RPE) were taken for the whole body, chest, legs, head, and other areas. No significant differences were found in overall RPE between deceived and control groups. However, there was a tendency for the Expected Increase group, deceived into believing the intensity would be higher than they were subsequently made to run, to experience an attenuated increase in RPE between runs compared to the control group (Control Increase) who were honestly informed. For all groups, legs and chest were given consistently higher localized exertion scores than the head and other areas. It appears that a precise system of afferent feedback mediates the overall perceived exertion response during high-intensity running, and psychological intervention that alters pre-exercise expectations has minimal feedforward effect on exertion ratings taken postexercise.

Reconsidering response sets, test-taking attitudes, dissimulation, self-deception, and social desirability.

This paper provides a summary of an examination of three lines of personality research involving response sets, empirical keying, and social desirability. The roots of these respective constructs are traced from their origins in Wundt's laboratory through the classic works of Meehl and Hathaway and Edwards up to Cattell's current reconstructions which take the form of trait-view theory and perturbation theory. After a careful analysis of the research and theoretical formulations from these three areas, it is concluded that Cattell's (1986) perturbation theory not only provides the most comprehensive system for understanding how respondents systematically distort their responses on personality questionnaires but also provides a solid framework for multivariate studies designed to test and refine his formulations.
