People are worse at detecting fake news in their foreign language.

Across two preregistered within-subject experiments ( = 570), we found that when using their foreign language, proficient bilinguals discerned true from false news less accurately. This was the case for international news (Experiment 1) and more local news (Experiment 2). When using a foreign (as opposed to native) language, false news headlines were always judged more believable, while true news headlines were judged equally (Experiment 2) or less believable (Experiment 1).

The Psychological Science Accelerator's COVID-19 rapid-response dataset.

In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments.

In COVID-19 Health Messaging, Loss Framing Increases Anxiety with Little-to-No Concomitant Benefits: Experimental Evidence from 84 Countries.

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively to the global public. Given that subtle differences in information framing can have meaningful effects on behavior, behavioral science research highlights a pressing question: Is it more effective to frame COVID-19 health messages in terms of potential losses (e.g.

Predicting attitudinal and behavioral responses to COVID-19 pandemic using machine learning.

At the beginning of 2020, COVID-19 became a global problem. Despite all the efforts to emphasize the relevance of preventive measures, not everyone adhered to them. Thus, learning more about the characteristics determining attitudinal and behavioral responses to the pandemic is crucial to improving future interventions.

National identity predicts public health support during a global pandemic.

Changing collective behaviour and supporting non-pharmaceutical interventions is an important component in mitigating virus transmission during a pandemic. In a large international collaboration (Study 1, N = 49,968 across 67 countries), we investigated self-reported factors associated with public health behaviours (e.g.

Perceived food palatability, blood glucose level and future discounting: Lack of evidence for blood glucose level's impact on reward discounting.

Some previous studies have shown that an increase in blood glucose level makes people more future oriented, however, results are inconsistent, other studies failing to replicate this effect. Here, we tested whether psychological factors (in this instance, perception of food pleasantness after consumption of more palatable or less palatable meal) can play a moderating role. We hypothesized that consuming more palatable food (perceived as rewarding) should cause blood glucose levels to affect future discounting, but that this should not occur for the consumption of less palatable food.

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation.

Thinking in a foreign language distorts allocation of cognitive effort: Evidence from reasoning.

Bilinguals, in their foreign language, are spared from several decision-making biases. We examined this "Foreign Language Effect" in the context of logical reasoning, in which reasoners are required to track the logical status of a syllogism, ignoring its believability. Across three experiments, we found the reverse Foreign Language Effect; foreign language reasoners are less able to evaluate the logical structure of syllogisms, but no less biased by their believability.

The moral foreign language effect is stable across presentation modalities.

People's judgements and decisions often change when made in their foreign language. Existing research testing this foreign language effect has predominantly used text-based stimuli with little research focusing on the impact of to audio stimuli on the effect. The only existing study on this topic found shifts in people's moral decisions only in the audio modality.

Foreign Language does not Affect Gambling-Related Judgments.

Previous work has demonstrated that peoples' gambling-related judgments (e.g., perceived likelihood of winning) are often biased by non-diagnostic unclaimed prize information (i.

Increasing blood glucose level via breakfast meals is not connected with changes in delay discounting.

Previous studies have revealed that increasing people's blood glucose level via drinking a soft drink containing sugar makes their financial decisions more future-oriented. This study extends these previous findings, testing whether the effect holds when blood glucose level is increased via intake of a normal meal (i.e.

The dissolution of temporal distance increases risk-taking: experimental evidence.

Earlier research shows that delaying the realization of a lottery (temporal distance) increases risk tolerance. Presumably, this happens because temporal distance protects one from encountering the negative emotions produced when facing risk. However, no study has tested whether people that made a choice in the presence of temporal distance would actually change their decision later on (in the absence of temporal distance), towards the safer choice.

The Dopamine Receptor D4 Gene () and Financial Risk-Taking: Stimulating and Instrumental Risk-Taking Propensity and Motivation to Engage in Investment Activity.

The Dopamine receptor D4 gene (DRD4) has been previously linked to financial risk-taking propensity. Past works demonstrated that individuals with a specific variant of the DRD4 gene (7R+) are more risk-seeking than people without it (7R-). The most prominent explanation for this effect is the fact that 7R+ individuals are less sensitive to dopamine and thus seek more stimulation to generate "normal" dopaminergic activity and feel pleasure.

Reading dilemmas in a foreign language reduces both deontological and utilitarian response tendencies.

Moral dilemmas entail deciding whether to cause harm to maximize overall outcomes, such as killing 1 person to save 5. Past work has demonstrated that people are more willing to accept causing such outcome-maximizing harm when they read dilemmas in a foreign language they speak rather than their native language. Presumably this effect is due to foreign dilemmas inducing reduced emotional impact, rather than increased cognitive processing, but previous work cannot distinguish between these possibilities because it treats them as diametric opposites.
