Ensuring the integrity of results in online learning and assessment tools is a challenge, due to the lack of direct supervision increasing the risk of fraud. We propose and evaluate a machine learning-based method for detecting anomalous behaviour in an online retrieval practice task, using an XGBoost classifier trained on keystroke dynamics and…

In the past two decades, individual explanations of scientific misconduct ('bad apples') have increasingly given way to systemic explanations ('bad systems'). Where did this interest in systemic factors (publication pressure, competition for research funding) come from? Given that research ethicists often present their interventions as responses…

Identifying illicit behavior in survey research is inherently problematic, since self-reports are untrustworthy. We argue that fraudulent interviewers can, however, be identified through statistical deviance of the distributional parameters of their interviews. We document that a high proportion of the variation in the data is due to the…

All banknotes have security features which are intended to help determine whether they are false or genuine. Typically, however, the general public has limited knowledge of where on a banknote these security features can be found. Here, we tested whether counterfeit detection can be improved with the help of salient elements, designed to guide…

The educational system today often relies on incentives in order to motivate students. However, it might also encourage students to engage in deceptive behaviour (e.g. malingering) in order to reach certain benefits. Hereby, we investigated whether students would intentionally fabricate symptoms (i.e. malinger) when confronted with a…

Children tell prosocial lies from the age of three years onward, but little is known about for whom they are inclined to lie. This preregistered study examined children's (N = 138, 9-12 years) prosocial lying behavior toward minimal in-group and out-group peers. Additionally, children evaluated vignettes in which an in-group peer told a prosocial…

It has been widely documented that accountability systems, including school inspections, bring with them unintended side effects. These unintended effects are often negative and have the potential to undo the intended positive effects. However the empirical evidence is limited. Through a European comparative study we have had the rare opportunity…

Little is known about the development of children's lying. The present study examined whether observed social and non-social fear in preschoolers predicts children's consistent cheating (N = 460; M = 4.3 years of age) and consistent lying about cheating. When left alone, 155 (34%) children cheated in both games conducted. Of these consistently…

The "Guidelines for Quality Provision in Cross-Border Higher Education" were developed and adopted to support and encourage international cooperation and enhance the understanding of the importance of quality provision in cross-border higher education. The purposes of the "Guidelines" are to protect students and other…

This study investigated whether emotions induced in TV-viewers (either as an emotional state or co-occurring with emotional involvement) would increase viewers' perception of realism in a fake documentary and affect the information value that viewers would attribute to its content. To that end, two experiments were conducted that manipulated (a)…
