The existence of pandemic fatigue has been debated fiercely. We introduce a theoretical conceptualization and brief measure of this construct. Using this measure across two large repeated cross- sectional surveys in Denmark and Germany, respectively, as well as one panel survey in Denmark (overall N = 34,582), we provide evidence for the existence...

During the current COVID-19 pandemic, governments must make decisions based on a variety of information including estimations of infection spread, health care capacity, economic and psychosocial considerations. The disparate validity of current short-term forecasts of these factors is a major challenge to governments. By causally linking an establi...

People differ fundamentally in their propensity to engage in bribery. Herein, we tested the effects of inequality of (monetary) resources between bribers (individuals who can offer bribes) and bribees (individuals who might receive bribes) on bribery. We implemented a bribery game where bribers and bribees could engage in bribery to benefit themsel...

To reach high vaccination rates against COVID-19, children and adolescents should be also vaccinated. To improve childhood vaccination rates and vaccination readiness, parents need to be addressed since they decide about the vaccination of their children. We adapted the 7C of vaccination readiness scale to measure parents’ readiness to vaccinate th...

During the COVID-19 pandemic, various behavioral measures were imposed to curb the spread of the virus. In a preregistered study based on a quota-representative sample of adult Danish citizens (N = 1,031), we compared the prevalence estimates of self-reported handwashing, physical distancing, and attitudes toward the behavioral measures between peo...

Building on the work of Zou et al. we (re-)investigated the relation between nostalgia and financial risk-taking across three preregistered, well-powered studies (overall N = 2,804). In Studies 1 and 2, we first tested whether nostalgia fosters or hampers dysfunctional or functional financial risk-taking. Finding no evidence to suggest that nostalg...

During COVID-19, conspiracy theories were intensely discussed in the media. Generally, both believing in specific conspiracy theories (i.e., explanations for events based on powerholders’ secret arrangements) and the general tendency to believe in conspiracy theories—a so-called conspiracy mentality—have been found to predict cognition and behavior...

Individuals and institutions around the world have been affected by the coronavirus disease 2019 (COVID-19). Herein, we investigate the role of basic (Big Five and HEXACO) and specific (Dark Factor of Personality, Narcissistic Rivalry, and Narcissistic Admiration) personality traits for 17 criteria related to COVID-19, grouped into (i) personal per...

During the COVID-19 pandemic, different behavioral measures were imposed to curb the spread of the virus. In a pre-registered study based on a quota-representative sample of adult Danish citizens (N = 1,031), we compared the prevalence estimates of self-reported handwashing, physical distancing, and attitudes towards the behavioral measures between...

The Coronavirus Disease 2019 (COVID-19) has strongly affected individuals and societies worldwide. In this review and meta-analysis, we investigated how aversive personality traits – that is, relatively stable antisocial personality characteristics – related to how individuals perceived, evaluated, and responded to the COVID-19 pandemic. Across 34...

It is often important to study people’s thoughts, feelings, and behaviors over time. To this end, researchers have relied on repeated cross-sectional studies, in which different people from the same population participate on different measurement occasions. Also, researchers have relied on panel studies, in which the same group of people participat...

Although vaccines are among the most effective interventions used in fighting diseases, vaccination readiness varies substantially among individuals. Vaccination readiness is defined as a set of components that increase or decrease the individual’s likelihood of getting vaccinated. Building on earlier work that distinguished five components of vacc...

The COVID-19 pandemic has required massive behavioural adaptions to curb the spread of the disease. Since March 2020, the COVID-19 Snapshot MOnitoring (COSMO) survey has assessed (and will continue to do so) Danish citizens’ perceptions and behavioural reactions to the COVID-19 pandemic. Herein, we report selected results of the COSMO survey, highl...

Introduction In this study, we show new evidence for the role of ventrolateral prefrontal cortex‐dorsolateral prefrontal cortex (VLPFC‐DLPFC) networks in the cognitive framing of emotional processing. Method We displayed neutral and aversive images described as having been sourced from artistic material to one cohort of subjects (i.e., the art‐fra...

Believing in specific conspiracy theories (i.e., explanations for events based on powerholders’ secret arrangements) as well as the general tendency to believe in conspiracy theories—a so-called conspiracy mentality—predicts cognition and behavior with negative societal effects, such as low institutional trust and less societal engagement. During C...

Dishonest and fraudulent behavior poses a serious threat to both individuals and societies. Many studies investigating dishonesty rely on (one of) a few well‐established lab and online cheating paradigms. Quite surprisingly, though, the external validity of these paradigms has only been investigated in a small number of studies, raising the questio...

Computerized versions of population inferred cheating tasks (C-PICT)—i.e., tasks in which dishonesty is statistically determined on the aggregate by comparing self-reported outcomes with a known probability distribution—have become increasingly popular. To this date no study has investigated whether non-computerized population inferred cheating tas...

This study protocol is based on a standard protocol published by the World Health Organization/Regional Office for Europe (1), aimed at providing a general guidance on how to assess citizens’ knowledge, perceptions, and behaviour related to the COVID-19 outbreak. As the aims, objectives, and research questions are similar across countries, we refer...

Are highly intelligent people less risk averse? Over the last two decades scholars have argued the existence of a negative relationship between cognitive ability and risk aversion. Although numerous studies support this, the link between cognitive ability and risk aversion has not been found consistently. To shed new light on this topic, a systemat...

Many university students report being stressed which has been linked with various negative outcomes. The primary purpose of this study was to explore the selection effects of different admission procedures on students’ stress level. The sample consisted of 196 students who had been admitted to the psychology program at the University of Southern De...

Virtual reality (VR) is projected to play an important role in education by increasing student engagement and motivation. However, little is known about the impact and utility of immersive VR for administering e-learning tools, or the underlying mechanisms that impact learners’ emotional processes while learning. This paper explores whether differe...

Mange ledere oplever stress som en del af deres hverdag, bl.a. som følge af det krydspres mange skal navigere i. Indsatser til at komme problemet til livs synes ikke at stå mål med udbredelsen af problemet. Det er således et anseligt problem, da en stresset leder ikke er en god leder. Artiklen vil med afsæt i den eksisterende stressforskning og vor...

Presence is one of the most important psychological constructs for understanding human-computer interaction. However, different terminology and operationalizations of presence across fields have plagued the comparability and generalizability of results across studies. Lee’s (2004) unified understanding of presence as a multidimensional construct ma...
