Hans IJzerman’s Associate Director Nomination

I find the Psychological Science Accelerator one of the more exciting initiatives in psychological science. The PSA can potentially solve many known complicated challenges within our discipline. From complex problems pertaining to replicability, generalizability, strategy selection, inferential reproducibility, and computational reproducibility, PSA’s Big Team Science approach has the potential to tackle them all. And yet,Continue reading “Hans IJzerman’s Associate Director Nomination”

Cleansing effects still lack empirical support: Rejoinder to Lee and Schwarz’ rejoinder

This blog post was written by Ivan Ropovik and Hans IJzerman. This blogpost is cross-posted at PsyArxiv. In Spike W. S. Lee and Norbert Schwarz’ recently published BBS target article “Grounded procedures: A proximate mechanism for the psychology of cleansing and other physical actions” (2020), the authors outline proximal mechanisms underlying so-called cleansing effects. InContinue reading “Cleansing effects still lack empirical support: Rejoinder to Lee and Schwarz’ rejoinder”

How to bring the gezelligheid this pandemic winter into your home

One of the things we will miss possibly the most this pandemic winter in the Northern Hemisphere is gezelligheid [ɣəˈzɛləxɛit]. No real English equivalent of gezelligheid exists; the closest word in the English vernacular – coziness – still doesn’t capture the same feeling of intimacy and belonging. What does communicate a similar sentiment and is more familiar to US ears is the Danish concept hygge [hʊɡə] and the Swedish concept of lagom. Wikipedia describes gezelligheid as “’conviviality’, ‘coziness’, ‘fun’” or “just the general togetherness that gives people a warm feeling”.

A Manifesto for Big Team Science: Talk at AFC

March 11, 2021, Patrick Forscher gave a talk (online) at the Applied Face Cognition lab, led by Meike Ramon and for the Swiss Reproducibility Network. Below first the video of his talk and then the abstract. Abstract Progress in psychology has been frustrated by challenges concerning replicability, generalizability, strategy selection, inferential reproducibility, and computational reproducibility.Continue reading “A Manifesto for Big Team Science: Talk at AFC”

Are Theories Actually Practical?

This quote is often attributed to the person hailed as the “father of social psychology”, Kurt Lewin. In social psychology textbooks, the quote is used to justify a mode of social psychology whereby theories that are developed and tested in the lab “naturally” and “inherently” lead to useful social applications

CORE Lab Journal Club (January 22, 2021): Enhancing the Realism of Simulation

During our journal club, we discuss a variety of articles. Some of them are focused on specific topics, but many of them are focused on broader methods (for a full list, see the featured image). During last meeting (January 22, 2021), we discussed the value of computational modeling. We used Wander Jager’s article “Enhancing theContinue reading “CORE Lab Journal Club (January 22, 2021): Enhancing the Realism of Simulation”

How should we fund the PSA?

In our previous post, we argued that the PSA has a grand vision and a budget that cannot easily support it. If the PSA is to fulfill its aspirations, the PSA must increase its funding so that it can support an administrative staff.
In this post, we will assume that the PSA wants to fulfill its grand vision. We will therefore explore ways that the PSA could create the funding streams that are necessary to achieve that vision.

Creating a psychological tool applicable to individuals around the world (STRAEQ-2 item generation and selection phase).

In one of my projects of my PhD, I – Olivier – am working on developing and validating a scale (the Social Thermoregulation, Risk Avoidance, and Eating Questionnaire – 2, or the STRAEQ-2). In the first phase of this project, we involved people from different countries and asked them to generate items. We did soContinue reading “Creating a psychological tool applicable to individuals around the world (STRAEQ-2 item generation and selection phase).”

The financial cost of the PSA’s vision

In 2017, Chris Chartier shared a blog post that revealed a grand vision for psychology research: psychologists could build a “CERN for psychology” that does for psychology what particle accelerators have done for physics. This “CERN for psychology” would be an organization that harnessed, organized, and coordinated the joint efforts of psychology labs throughout the world to take on large, nationally diverse big team science projects.

Proposing a PSA-affiliated paid translation service with a first focus on Africa

Psychological science is dominated by researchers from North America and Europe. The situation in Africa exemplifies this problem. In 2014, just 6 of 450 samples (1.4% of the total) in the journal Psychological Science were African. In Africa, language issues exacerbate the more general problem of underrepresentation; only 130 million out of 1.3 billion Africans are proficient in English, despite 24 out of the 54 countries having English as their official language. We propose a paid translation service that can help overcome this problem.

CORE Lab 2020 Lab Philosophy/Workflow Hackathon

Today, September 16, 2020, we organized the yearly lab philosophy/workflow hackathon of the CORE Lab. To get all the lab members on one page and to reduce error as much as possible, we have a lab philosophy that is accompanied by various documents to facilitate our workflow. But research standards evolve and we also oftenContinue reading “CORE Lab 2020 Lab Philosophy/Workflow Hackathon”
