2019 May 20: A new paper with Dominik Bach is out at Nature Human Behavior. We are especially happy that Neil McNaughton wrote a wonderful News & Views piece about our article and a related article by the group of Dean Mobbs. We provide a decision-theoretic outlook on approach-avoidance conflicts (ACCs). Humans rely on predator probability & the optimal policy to solve an ACC framed as virtual foraging task. Predator probability was related to BOLD signals in hippocampus & amygdala. The optimal policy was related to medial prefrontal cortex. Behavioral data can be found here and here. Code can be found here. FMRI maps can be found here.

2018 July: Three newly accepted papers from the bachlab, on which I am a co-author: (1) The article in PLoS Computional Biology with Athina Tzovara as a first author uses psychophysiological modeling of skin conductance and pupil repossess to show that autonomous nervous system activity is best explained by a probabilistic learning model accounting for uncertainty in threat estimation (Tzovara, Korn, Bach, in press). (2) A new review paper in the journal Psychophysiology summaries current theories and available methods for psychophysiological modelling (Bach, Castegnetti, Korn, et al., in press). (3) A paper in Translational Psychiatry (Bach, Korn, Vunder, Bantel, in press) considerably extends previous work on approach-avoidance conflicts (Korn, Vunder, Miró, et al., 2017) by demonstrating effects of two drugs related to GABAergic signaling, pregabalin and valproate.
2018 June: New paper by the lab of Sabine Herpertz, on which I am a co-author. The article in the journal Personality Disorders with Haang Jeung as a first author examines the emotional responses of Borderline Personality Disorder (BPD) patients after exchanging personal opinions in a novel virtual peer interaction paradigm. I am very happy that Sabine Herpertz and her lab have agreed to collaborate on projects testing social cooperation in BPD patients (with funding provided by the Emmy-Noether research group).
2018 June: The German Research Foundation (DFG) has awarded me an Emmy-Noether research group. I am very thankful to the DFG for this exciting opportunity and I am really looking forward to setting up a group in December 2018.
2018 June: It was a pleasure to contribue to a workshop on Psycho-physiological Modeling in Gießen.
2018 May: It was a pleasure to attend the Symposium on the Biology of Decision Making in Paris.
2018 April: Two new papers accepted with Yulia Oganian and Hauke Heekeren in the Quaterly Journal of Experimental Psychology. (1) Three online studies – one of them pre-registered – show that using a foreign language with low proficiency reduces comparitive optimism (Oganian, Heekeren, Korn, 2018). (2) In contrast, framing effects in minimally verbal settings are robust to foreign language use and to switching between languages (Korn, Heekeren, Oganian, 2018).
2018 January: New paper out with Dominik Bach in Nature Communications (see here). Model comparisons show that humans trade off optimal and heuristic decision policies during sequential decision-making. Parts of the medial prefrontal cortex are involved in computations of the the used decision policies, their uncertainties, and the discrepancies between them (Korn & Bach, 2018).
2018 January: New paper out with Gabriela Rosenblau and Kevin Pelphrey in Journal of Neuroscience. The same reinfocement-learning-based model describes how adults and adolescents learn about the preferences of their peers but adolescents are more conservative (Rosenblau, Korn, Pelphrey, 2018).
2017 December: I am very happy to receive € 27k in funding from a UKE young investigator scheme for experiments testing for the representations of concrete and abstract (i.e., social) stimuli in the medial prefrontal cortex.
2017 November: Two posters at SfN: (1) Modulation of cross-modal integration by reward learning (2) A model combining reinforcement learning and self-evaluations explains how humans learn about character traits
2017 October: New paper out in Psychonomic Bulletin and Review with Henrik Saalbach, Lennart Schalk, and Yulia Oganian. The framing effect is one of the most prominently discussed decision biases. Here, we test whether the framing effect can be reduced by a manipulation of font readability, which has been argued to trigger deeper cognitive processing. In two initial studies we find no influence of font readability. A weak effect only emerges in a large, pre-registered online study (Korn, Ries, Schalk, et al., 2017).
2017 September: SPM course in Hamburg. Presentations on experimental design and multivariate analysis techniques.
