Determinants of motivated behavior are linked to fatigue and its perturbation by SARS-CoV-2 vaccination

New preprint out! In this very collaborative research project, we assessed the impact of a SARS-CoV-2 vaccination on determinants of motivated behavior: mental and physical exhaustion. To do so, we made use of a novel experimental paradigm (developed and extensively piloted by first author David S. Stolz), the Learn/Effort-task, to quantify these sub-facets of motivated …

New collaborative publication with the PNI out!

The contribution of sleep to the neuroendocrine regulation of rhythms in human leukocyte traffic The first cooperative paper between the Social Neuroscience Lab and Psychoneuroimmunology (Prof. Tanja Lange; Department of Rheumatology & Clinical Immunology) is out!  In our review, we summarize how 24-h rhythms in leukocyte traffic are regulated by neuroendocrine mediators and how this is supported by …

Lab visit by Geert-Jan Will

Today, we had a spectacular visit by Geert-Jan Will from Utrecht University who presented his research on the computational mechanisms of self-esteem formation and its relevance for psychiatric conditions. Moreover, we took advantage of the situation (first real-life lab visit after 1.5 years) to discuss links between self-related belief formation, affect, subjectively perceived control, effort exertion, …

Neurocomputational mechanisms of affected beliefs

Abstract The feedback people receive on their behavior shapes the process of belief formation and self-efficacy in mastering a given task. The neural and computational mechanisms of how the subjective value of these beliefs and corresponding affect bias the learning process are yet unclear. Here we investigate this question during learning of self-efficacy beliefs using …

New publication on self-related learning processes out in Scientific Reports!

Self-beneficial belief updating as a coping mechanism for stress-induced negative affect.   Very cool new computational modeling paper by Nora Czekalla et al. on how stress/affect are better recovered depending on the way people integrate novel information about themselves into their self-concept. With this new data we replicate and extend earlier findings of a negativity …
