Abstract. Age-related decline in episodic memory performance is a well-replicated finding across numerous studies. Recent studies focusing on aging and ind

Happy to be back in Marburg again! Tomorrow, I will be discussing EEG markers of reward and threat positive prediction errors. Looking forward to it! 🙏
Today, the "Marburg Conference on Expectations and their Violations" of the research training group @rtg2271 begins. Looking forward to exciting presentations and discussions at #UniMarburg at the Department of Psychology https://t.co/rYjxXAoVjX

We have a new preprint by Jonas Simoens, Tom Verguts, and myself, where we wanted to investigate whether people can learn to associate different environments to different learning rates? https://t.co/25fHijVRH9.

Very happy to share our new paper (@stolzch, @ad_pickering, & @mellr_erek) showing that feedback valence effects on brain oscillations 🧠 depend on the learning context, here monetary reward vs. threat avoidance learning.

Brain responses to negative feedback depend on the consequences: receiving punishment vs. not receiving reward! New paper by @stolzch: Dissociable feedback valence effects on frontal midline theta during reward gain versus threat avoidance learning

The highlight of the present study is the direct comparison of frontal theta EEG oscillations (FMθ) during monetary reward vs. threat avoidance reinforcement learning using titrated monetary reward...

Stoked to share our latest preprint showing that the relationship between trait openness to experience and episodic memory performance in older adults was mediated by memory brain-network activity during encoding. @JoramSoch @SchottBjorn

Had such a great time discussing research with new and old colleagues/friends at the @TheRealSPR 2022 meeting. Vancouver has so many beautiful places; def gonna visit again. Photos show North Shore mountains, waterfront, Burrard Street, and Kyuss + Bathory LPs from @Audiopile_ 😎

So happy that our personality neuroscience poster on associations between trait openness to experience, aging, and functional memory encoding was honored with a SPR poster award. (C. Stolz, A. Bulla, @JoramSoch, @SchottBjorn, & A. Richter). @LIN_Magdeburg @DZNE_en MD @OVGUpresse
Congratulations to the ten poster winners from #2022SPR. Posters are judged for a clear statement of the research problem; sound methods and statistical analysis; the appropriateness and clarity of figures and graphics; and a concise and well-organized presentation.

Unfortunately not (quite the contrary 😢) @mael_lebreton, @sophiebavard, Jean Daunizeau + me, showed that model-based fMRI can actually generate spurious correlations, which explains why results "model parameter x correlates with activity in area X in our (n=20) study" are common

Inakzeptabel. Corona besiegen wir als Gesellschaft nur gemeinsam. Polemische Angriffe gegen Wissenschaftler wie jetzt durch die @BILD-Zeitung sind inakzeptabel & kontraproduktiv. Die #AllianzWissenschaft fordert mehr Sachlichkeit in Krisensituationen. https://t.co/ErQl6aoUr7

Excited to share our new #ViolEx 2.0 model: an interdisciplinary framework to investigate when and why violated #expetations are updated - or persist despite disconfirming evidence.

I think this deserves attention from anyone working on improving (?) models of the n-choice paradigms (including me) and it can certainly not being dismissed on account of being a rant from two frustrated scientists... https://t.co/6irh5DcX9p
