The COVID-19 pandemic has increased negative emotions and decreased positive globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce increase emotions, we tested the effectiveness reappraisal, an emotion regulation strategy which modifies how one thinks about situation. Participants from 87 countries/regions (N = 21,644) were randomly assigned to two brief reappraisal interventions (reconstrual or repurposing) control conditions (active...
Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment ( n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of messages promoted personal agency reflective choices (i.e., an autonomy-supportive message) or were restrictive shaming controlling compared with no message at all. Results partially...
Abstract: Background: The Psychological Science Accelerator (PSA) recently completed a large-scale moral psychology study using translated versions of the Oxford Utilitarianism Scale (OUS). However, have no validity evidence. Objective: investigated structural evidence OUS across 15 and produced version-specific reports. Methods: We analyzed data from PSA, which was collected internationally on centralized online questionnaire . also qualitative feedback experts for each version. Results:...
Semantic priming has been studied for nearly 50 years across various experimental manipulations and theoretical frameworks. Although previous studies provide insight into the cognitive underpinnings of semantic representations, they have suffered from small sample sizes a lack linguistic cultural diversity. In this Registered Report, we measured size variability effect 19 languages (N = 25,163 participants analyzed) by creating largest available database values based on an adaptive sampling...
According to the justified true belief (JTB) account of knowledge, people can truly know something only if they have a that is both and (i.e., knowledge JTB). This was challenged by Gettier, who argued JTB does not explain attributions in certain situations, later called “Gettier-type cases,” wherein protagonists are believing be true, but their correct because luck. Laypeople may attribute with luckily beliefs. Although some research has found evidence for these so-called Gettier...
Over the past 10 years, Oosterhof and Todorov’s valence–dominance model has emerged as most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence dominance) underpin judgements faces. Because primarily been developed tested in Western regions, it is unclear whether these findings apply to other regions. We addressed question by replicating methodology across 11 world 41 countries 11,570 participants. When we used original analysis...
Classic findings from psychology and the behavioural sciences are increasingly being revisited. Methodological technological advances provide opportunities to replicate studies across a wide range of countries settings investigate whether these universally applicable, limited specific countries, or vary in magnitude depending on settings. Researchers around world connect revisit such collaboratively, adapt original design Zeitgeist, integrate new knowledge improve statistical analyses,...
Abstract In response to the COVID-19 pandemic, Psychological Science Accelerator coordinated three large-scale psychological studies examine effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions affective measures. The data collected (April October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors experience, geographical cultural context characterization,...
According to the Justified True Belief account of knowledge (JTB), a person can only truly know something if they have belief that is both justified and true (i.e., belief). This was challenged by Gettier (1963), who argued JTB does not explain attributions in certain situations, later called Gettier-type cases, wherein protagonist believing be but their correct due luck. Lay people may attribute protagonists with luckily beliefs. While some research has found evidence for these so-called...

The COVID-19 pandemic (and its aftermath) highlights a critical need to communicate health information effectively the global public. Given that subtle differences in framing can have meaningful effects on behavior, behavioral science research pressing question: Is it more effective frame messages terms of potential losses (e.g., “If you do not practice these steps, endanger yourself and others”) or gains protect others”)? Collecting data 48 languages from 15,929 participants 84 countries,...

Biases in favor of culturally prevalent social ingroups are ubiquitous, but random assignment to arbitrary experimentally created groups is also sufficient create ingroup biases (i.e., the minimal group effect; MGE). The extent which bias arises from specific contexts versus more general psychological tendencies remains unclear. This registered report focuses on three questions. First, how MGE? Second, do critical cultural and individual factors moderate its strength? Third, does MGE...
Though people usually imagine the typical person as a man rather than woman, effect is mixed for racial groups and understudied among traditionally male social (e.g., police criminals) non-U.S. populations. Results from survey (N > 5000) collected via globally distributed laboratory network in over 40 regions demonstrated that attitudes toward Black politicians had stronger relationship with men women of group. However, White men, whereas East Asian people, officers, criminals did not...

Mental simulation theories of language comprehension propose that people automatically create mental representations objects mentioned in sentences. representation is often measured with the sentence-picture verification task, wherein participants first read a sentence implies object property (i.e., shape and orientation). Participants then respond to an image by indicating whether it was from or not. Previous studies have shown matching advantages for shape, but findings concerning...
This paper examined the nature of publications in Big Team Science (BTS): large-scale collaborations between multiple researchers at institutions. These projects can improve research by initiating that span across globe, age groups, education levels, and subfields research. As number BTS increase, it is useful to explore who currently involved determine diversity both subject researcher representation. We authors more than half a million articles investigate where what published, author...
The planning of sample size for research studies often focuses on obtaining a significant result given specified level power, significance, and an anticipated effect size. This requires prior knowledge the study design statistical analysis to calculate proposed However, there may not be one specific testable from which derive power [@silberzahn2018many] or hypothesis test project (e.g., creation stimuli database). Modern suggestions include accuracy in parameter estimation [AIPE,...
