Full-text available
Most psychological studies rely on student samples. Students are usually considered as more homogenous than representative samples both within and across countries. However, little is known about the nature of the differences between student and representative samples. This is an important gap, also because knowledge about the degree of difference...

Most published research focuses on describing differences, while neglecting similarities that are arguably at least as interesting and important. In Study 1, we modified and extended prior procedures for describing similarities and demonstrate the importance of this exercise by examining similarities between groups on 22 social variables (e.g., mor...

Members of extreme political groups are usually perceived as more homogeneous than moderates. We investigated whether members of the general public who share the same political ideology would exhibit different levels of heterogeneity in terms of human values across 20 European countries and Israel. We directly compared the variability across modera...

Researchers are increasingly noticing the value of multiverse analysis. While such analysis is important, they should not neglect the impact of multiverse operationalisations on the outcome – that is, multiple ways of operationalising or measuring constructs such as well-being or religiosity. The “Many Analysts Religion Projects” (2022) found that...

Perceived polarization between US Democratic and Republican voters has grown over past decades, and this polarization underpins a dwindling sense of hope about the future. Contrary to this trend, the present three experiments (one pre-registered) with 2,529 US participants found substantial similarities between the groups in their fundamental value...

Abstract: Conspiracy beliefs have spread during the Covid-19 pandemic. Such beliefs are important to understand because of their potential to underpin distrust in societal institutions and vaccine hesitancy. In the present research (N = 538), we assessed the links between conspiracy beliefs, trust in institutions (e.g., government, WHO), and attitu...

As automation advances and markets transform, creative skills are becoming increasingly important. In the present study (N = 813), we therefore investigate how creative performance can be enhanced. Participants either participated in a fun recreational game, a fun-focused game, a math task, or none (control condition). This allowed us to analyze th...

We examined how different types of communication influence people’s responses to health advice. We tested whether presenting COVID-19 prevention advice (e.g., washing hands/distancing) as either originating from a government or scientific source would affect people’s trust in and intentions to comply with the advice. We also manipulated uncertainty...

Objectives Postnatal depression is the most prevalent psychopathology experienced within the perinatal period and has been associated with a range of adverse outcomes for both mother and infant.

The 21-item Depression, Anxiety, and Stress Scale (DASS-21) is a common instrument for measuring dimensions of emotional distress. In the present research, we tested across five studies (N = 2,096) whether the number of items could be reduced while maintaining high reliability and validity. Specifically, Item Response Theory and Confirmatory Factor...

Many domains of research suggest that high favorability to social power and low favorability to egalitarian ideals predict more prejudice against other groups. In the present article, we describe theory and evidence suggesting that the relations between power, egalitarianism, and prejudice may be reversed for one group: fat men. Using both implicit...

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct.

Environmental knowledge is considered an important pre-cursor to pro-environmental behaviour.

After police killings such as the one of George Floyd, trust in the police in the USA has plummeted.

People can support their abstract reasoning by using mental models with spatial simulations. Such models are employed when people represent elements in terms of ordered dimensions (e.g., who is oldest, Tom, Dick, or Harry). We test and find that the process of forming and using such mental model can influence the liking of its elements (e.g., Tom,...

Brazil is one of the epicenters of the COVID-19 pandemic (i.e., 563,470 deaths until August 9th, 2021).

Question
Are you aware of any Prolific Academic/mturk alternative with Japanese and Malay participants (n = 300/country)? We are planning to run a cross-cultural study including Japan and Malaysia and might have the funding to pay each participant US-$1.50-2.00 to participate in a 10-12min online study. Ideally, participants would be 30+ years of age from the general public. Recruitment services such as those offered by Qualtrics would be too expensive.
Question
How can I compare the interaction terms of two separate polynomial regressions? Both regressions look like
y = x1 + x2 + (x1)^2 + (x2)^2 + x1*x2
Also, how can two interaction terms from the same regression be compared?
And how would you determine the statistical power for doing so?
Thanks!
Question
with df1 = 1 und df2 = 6. This blog suggests that a Cramer's V with df1 = 1 can be interpreted similarly to Pearson's r, do you agree?
If not, are you aware of any way how Cramer's V can be converted to r or d?

Question
Hi all, I am looking for datasets containing variables of environmental behavior on a country level. Specifically, on any kind of behavior which can affect the environment, both positively and negatively.
For example, recycling rates (per country), percentage of people who commute by bicycle, amount of plastic used, % of renewable energies, deforestation in the last decades etc. Ideally, data should be available for at least 30 countries. It is easy to find data on carbon emissions, but I am struggling to find other variables. Any suggestions?
Question
Hello,
I am looking for a way of how to compare Brown and Hauenstein's (2005) agreement index awg (independent awgs). Ideally, this method should also allow to compare the mean awgs: I got several states and two groups (e.g., women and men) in each state. I now wanna test whether people in one group agree on average more across all states than people in the other group.
Thanks
Paul
