Attitudes toward mandatory vaccination and the Covid certificate as a function of vaccination status and risk perception
In January 2022, several vaccination policies were debated to address the Omicron outbreak in Belgium. Considering variability in risk perception and vaccine uptake, this study aimed to understand differences in support and expectations for four scenarios, ranging from relaxed to restrictive vaccination policies, to inform policymakers. Using an online survey, 12,670 participants (46% female; M age = 45.9, SD = 13.38) reported their risk percepti…
Trajectories of health behaviors during the Covid-19 pandemic
AIM: This study aimed to investigate the associations between health behavior adherence and psychological factors during the COVID-19 pandemic, with a particular focus on identifying trajectories of handwashing, mask wearing, social contact limitations, and physical distancing. METHODS: We employed a multi-trajectory group-based approach to analyze data from 6026 Belgian residents, including 60% women, with an average age of 52.65. Data were coll…
The role of self-compassion in loneliness during the Covid-19 pandemic
Research has suggested an increase in loneliness during the COVID-19 pandemic, but much of this work has been cross-sectional, making causal inferences difficult. In the present research, we employed a longitudinal design to identify loneliness trajectories within a period of twelve months during the COVID-19 pandemic in Belgium (N = 2106). We were particularly interested in the potential protective role of self-compassion in these temporal dynam…
Risk perception as a motivational resource during the Covid-19 pandemic
These findings suggest that risk severity served as a critical and dynamic resource for adherence to behavioral measures because it fostered greater autonomous regulation
Introducing the brief reverse correlation
The reverse correlation is an innovative method to capture visual representations (i.e., classification images, CIs) of social targets. However, this method necessitates many trials to compute high‐quality CIs, which poses important practical and economic challenges. We introduce a new version of the reverse correlation method, namely, the Brief‐RC. By increasing the number of stimuli (i.e., noisy faces) presented at each trial, the Brief‐RC impr…
When views about alternative medicine, nature and god come in the way of people's vaccination intentions
In spite of the safety and efficiency of the COVID‐19 vaccines and the many promotion efforts of political and expert authorities, a fair portion of the population remained hesitant if not opposed to vaccination. Public debate and the available literature point to the possible role of people's attitudes towards medical institutions as well as their preference for complementary and alternative medicine (CAM) on their motivations and intentions to …

The Role of Communication Style and External Motivators in Predicting Vaccination Experiences and Intentions
45.99) how health care workers could foster reflection about and intentions to get vaccinated against COVID-19 by experimentally varying their communication style (i.e., autonomy-supportive vs. controlling) and the reference to external motivators (i.e., use of a monetary voucher or corona pass vs. the lack thereof). Each participant was randomly assigned to one of six conditions and rated a vignette in terms of anticipated autonomy satisfaction,…
Psychological science and its societal mission during the Sars‐CoV‐2 pandemic
Upon the outbreak of the SARS‐CoV‐2 virus, it was clear that the pandemic would not only entail physical but also psychological challenges and threats to individuals’ sustained motivation, behavioral adherence, and mental health. To encourage the Belgian authorities to take these psychological aspects into account, the Motivation Barometer, a large‐scale and dynamic survey, was launched in March 2020. Its purpose was to monitor cognitive, affecti…
Predicting health behaviors across Belgium and France during the first wave of Covid-19 pandemic
The objective of the current research was to investigate how a series of psychological factors may underlie two COVID-19 health behaviors, and how a contextual factor (country of residence) could shape their influence. Cross-sectional results from the first pandemic wave ( NBelgium = 4878, NFrance = 1071) showed that handwashing and social contacts limitation are predicted by a unique set of psychological variables that holds across Belgium and F…
The relation between conspiracism, government trust, and Covid-19 vaccination intentions
When my actions shape your looks
The literature on the approach/avoidance training (AAT) effect has focused on its evaluative consequences (with approached stimuli evaluated as more positive than avoided ones). Building on a grounded cognition framework, we investigated AAT effects on the visual representation of stimuli (here, neutral faces). We formulated specific predictions regarding the facial features that should be the most biased and the conditions under which the effect…
Direct and indirect dimensional compensation
Dimensional compensation takes place when perceivers judge one of two social targets higher on one of the two fundamental dimensions while judging the other target higher on the second dimension. Interestingly, the majority of studies on the dimensional compensation effect focused on direct measures, with almost no attempt to rely on more indirect measures. We tested whether dimensional compensation also takes place at a more indirect level (Brie…

Democracia vs neoliberalismo económico. Condicionantes ideológicos de las preferencias políticas y económicas en la ciudad de Lima
Este estudio analiza la influencia de la ideología política sobre tres actitudes sociopolíticas: el apoyo al modelo económico neoliberal, el apoyo al sistema político democrático y el desinterés por la política, en una muestra de adultos jóvenes de la ciudad de Lima ( N = 279 ). Como medidas de ideología política se utilizaron escalas de autoritarismo de ala derecha (RWA), orientación hacia la dominancia social (SDO), orientación política de dere…

Der Begriff des Politischen
Angesichts der zahlreichen zustimmenden wie ablehnenden Äußerungen zu Schmitts Abhandlung »Der Begriff des Politischen« ist es erstaunlich, daß die Schrift niemals Gegenstand einer systematischen Interpretation geworden ist, so daß die Kritik — so wertvoll ihre Einsichten im einzelnen sein mögen — das Gefüge der Abhandlung noch nicht in den Blick heben konnte1.
