After submission of my manuscripts, I post (nearly) all of them on the Social Science Research Network. You can access them by clicking on the image above.
Research In Progress
You can follow some of my in progress work by going to my OSF profile page. If you are interested in projects that are ongoing, but not open (yet), please get in touch.
Are you a non-scientist, and interested in solid, well-written psychological science? Check out the Open Access In-Mind Magazine (available in English, Dutch, Italian, and German). I founded In-Mind in 2006.
Access my published papers and citations @ Google Scholar.

Here you will find more information about Hans IJzerman's research and teaching, which predominantly focuses on social thermoregulation. For more information browse the page or get in touch.
After a few months, we have finally gotten around to submitting a new version of the Human Penguin Project. Content is largely the same (though very much fine-tuned). Abstract available below, manuscript can be downloaded – for free – from PsyArxiv. Abstract Social thermoregulation theory posits that modern human relationships are pleisiomorphically organized around Read more about New version of HPP submitted: Climate, Social Integration, and Core Body Temperature[…]
We just submitted a new version of our Human Penguin Project, and the preprint we made available immediately (for free) on PsyArxiv. Article can be downloaded here and abstract available below. Abstract Social ties in general, but having a wider variety of social ties (i.e., complex social integration) specifically, have been shown to create important physical Read more about Submitted a new version of the Human Penguin Project[…]
We just had a new article accepted in which we discuss the role of sensor and actuator technology in relationship therapy. The article is a somewhat logical continuation of our earlier work in which we suggested that attachment is “radically embodied” (cf. Beckes et al., 2015). Based on the available literature, we conclude that modern relationships Read more about Article accepted! Modernizing relationship therapy through Social Thermoregulation Theory.[…]
We were able to revise and resubmit our supervised machine learning paper on the Stroop effect. We applied supervised machine learning on the ManyLabs 3 data and got pretty surprising results. What they are exactly, check out the paper. The really nice feature of the revision is that we added in extra thresholds to determine Read more about Machine learning paper on the Stroop effect resubmitted[…]
In a previous post, we reported on a pilot test that is part of our replication project of Förster et al. (2008) as part of ManyLabs 5. In this post we provide the links so that followers of this project can get live updates, as the data come in. The main goal of the original paper was Read more about The Hidden Moderator Part II – Live Updates on Pilot 2[…]
Our work on social thermoregulation was extensively covered in the March 2017 issue of the Scientific American Mind. In “The Warmth of Friendship, The Chill of Betrayal”, Marta Zaraska writes extensively about the evolutionary advantages of sharing body heat and what the consequences are for modern relationships. She also contrasts this/our perspective with more cognitive, conceptual metaphor-like theories (see Read more about Our work covered in Scientific American Mind![…]
Blog post written by Hans IJzerman & Ivan Ropovik What constitutes a successful replication (1)? While a seemingly easy question, what the correct answer is has been rather controversial. The question as to what constitutes a successful replication has spurred intense debates about hidden moderators (Most Psychology Twitter Users, 2016-2017) and context sensitivity, often to the Read more about The Hidden Moderator Part I – Do we pay sufficient attention to piloting in replication studies?[…]
We have just submitted a revision of our article entitled “Modernizing Relationship Therapy through Social Thermoregulation Theory: Evidence, Hypotheses, and Explorations”. In the article, we review some of the available evidence on social thermoregulation in humans, review the sensors and actuators we use in our current research, and provide suggestions on how to craft Social Thermoregulation Therapy, which Read more about Revision submitted – Will we have Social Thermoregulation Therapy in the near future?[…]
We have just submitted a new manuscript and this is my first post @ PsyArxiv! In the manuscript, we find that people further from the equator have lower core temperatures, that people further from the equator score higher on complex social integration, and, importantly, that complex social integration protects core temperatures from the cold. The manuscript lends Read more about The Human Penguin Project: Social integration Protects against Colder Climates[…]
How does our modern life affect our sense of intimacy? This is a question we discussed last year at our NIAS-Lorentz Workshop in Leiden, where a number of people from the academy and from the tech industry got together to brainstorm. One of our visitors from back then, Barry Aarnoudse, will again organize – together with Read more about International Conference on Relationships, Attachment, and Technology: Can We Keep Up?[…]
