Assessing the truth effect’s reliability and test–retest stability
The finding that repeating a statement typically increases its perceived validity is referred to as the truth effect. Research on individual differences in the magnitude of the effect and its correlates is scarce and has yielded rather mixed results. However, any search for replicable relations between the truth effect and other cognitive or personality variables is bound to fail if the truth effect cannot be measured reliably at the individual l…
A New Approach to Detecting Cheating in Sensitive Surveys
Indirect questioning techniques such as the randomized response technique aim to control social desirability bias in surveys of sensitive topics. To improve upon previous indirect questioning techniques, we propose the new Cheating Detection Triangular Model. Similar to the Cheating Detection Model, it includes a mechanism for detecting instruction non-adherence, and similar to the Triangular Model, it uses simplified instructions to improve resp…
How explicit warnings reduce the truth effect
Prejudice against Women Leaders
Not to Be Considered Harmful
The number of respondents who access web surveys on a mobile device (smartphone or tablet) has been increasing rapidly over the last few years. Compared with desktop computers, mobile devices have smaller screens, different input options, and are used in a larger variety of locations and situations. The suspicion that the quality of data may suffer when online respondents use mobile devices has stimulated a growing body of research, which has mai…
Cocor
A valid comparison of the magnitude of two correlations requires researchers to directly contrast the correlations using an appropriate statistical test. In many popular statistics packages, however, tests for the significance of the difference between correlations are missing. To close this gap, we introduce cocor, a free software package for the R programming language. The cocor package covers a broad range of tests including the comparisons of…

Estimating the Prevalence of Nonpaternity in Germany
Surveying Multiple Sensitive Attributes using an Extension of the Randomized-Response Technique
The randomized-response technique (RRT) protects the privacy of respondents by adding random noise to their responses, such that there is no direct link between an individual's response and her true status. Although the RRT has repeatedly been shown to outperform direct questioning, it has rarely been used in survey research. First, it is difficult to survey multiple issues simultaneously. Second, traditional RRT models do not take the problem of…
Defection in the dark? A randomized‐response investigation of cooperativeness in social dilemma games
As previous research has demonstrated numerous times, humans show a robust tendency for cooperation. However, part—or indeed all—of this cooperativeness may be due to socially desirable responding. To address this problem, we propose and apply a new approach for the unbiased measurement of cooperativeness in social dilemma games. Specifically, we employ an extension of the randomized‐response technique (RRT). The RRT protects the privacy of respo…
No enhanced recognition memory, but better source memory for faces of cheaters
A randomized‐response investigation of the education effect in attitudes towards foreigners
While negative correlations have often been found between a respondent's education and his attitudes towards foreigners, the reasons for this education effect are still under debate. We examined the hypothesis that the highly educated may not be genuinely less xenophobic, but simply more prone to give socially desirable, xenophile answers in attitude questionnaires. We therefore compared the attitudes of respondents who were either questioned dir…
Evidence for Attenuated Affective Processing in Obesity
Attenuated affective processing is hypothesized to play a role in the development and maintenance of obesity. Using an affective priming task measuring automatic affective processing of verbal stimuli, a group of 30 obese participants in a weight-loss program at the Psychosomatic University Clinic Bonn (M age = 48.3, SD = 10.7) was compared with a group of 25 participants of normal weight (M age = 43.6, SD = 12.5). A smaller affective priming eff…
Probability misjudgment, cognitive ability, and belief in the paranormal
According to the probability misjudgment account of paranormal belief (Blackmore & Troscianko, 1985), believers in the paranormal tend to wrongly attribute remarkable coincidences to paranormal causes rather than chance. Previous studies have shown that belief in the paranormal is indeed positively related to error rates in probabilistic reasoning. General cognitive ability could account for a relationship between these two variables without assu…
Unequal Competition as an Impediment to Personal Development
The Relative Age Effect in Soccer
Previous findings of skewed birth date distributions among sports professionals have been interpreted as evidence for a systematic discrimination against children born shortly before the cut-off date for each age grouping. Alternative explanations for these findings exist, however. This research therefore attempted to replicate the effect in a cross-cultural comparison. A strong relative age effect in professional soccer was found in Germany, Jap…
Test anxiety versus academic skills
Background. Two competing theoretical models to explain academic performance were proposed. The interference model stresses the detrimental effect of task-irrelevant thoughts during the test-taking situation whereas the deficit model suggests Study Habits and domain-specific skills as main predictors of test performance.Aims. The study compares the two models by determining the relative contribution of Test Anxiety, Study Habits, and Maths Skill …
