Dopaminergic Mechanisms of Cognitive Flexibility: An [18F]Fallypride PET Study
New paper by Lena Rademacher, published in Journal of Nuclear Medicine, from our group! Abstract Cognitive flexibility is the ability to appropriately adapt one’s thinking and behavior to changing environmental demands and is conceptualized as an aspect of executive function. The dopamine system has been implicated in cognitive flexibility; however, a direct, that is,

Computational modeling shows confirmation bias during formation and revision of self-beliefs
Abstract Self-belief formation and revision strongly depend on social feedback. Accordingly, self-beliefs are subject to (re)evaluation and updating when facing new information. However, it has been shown that self-related learning is rarely purely information-driven. Instead, self-related learning is susceptible to a wide variety of biases. Among them is the confirmation bias, which can render updating
Altered physiological, affective, and functional connectivity responses to acute stress in patients with alcohol use disorder
Background There is evidence that the processing of acute stress is altered in alcohol use disorder (AUD), but little is known about how this is manifested simultaneously across different stress parameters and which neural processes are involved. The present study examined physiological and affective responses to stress and functional connectivity in AUD. Methods Salivary cortisol
Examining self-belief formation through artificial beliefs
Abstract Psychological research has addressed key questions about self-beliefs, such as when they are formed, how they are shaped, or what functions they might have. The fundamental question of how we arrive at these self-beliefs in the first place has mostly been neglected, and there is currently no mechanistic description of the underlying processes. While

The Human Affectome
Abstract Over the last decades, the interdisciplinary field of the affective sciences has seen proliferation rather than integration of theoretical perspectives. This is due to differences in metaphysical and mechanistic assumptions about human affective phenomena (what they are and how they work) which, shaped by academic motivations and values, have determined the affective constructs and

Rethink funding!? New paper and Shiny App published
Rethink funding!? Every funding agency, be it the German (DFG), Swiss (SNF), British (Wellcome Trust), US American (NIH), Chinese (NSFC), or French (ANR) research foundation, has its own scheme on how to allocate research funding to the researchers. And research funding determines what is considered good science, it controls future science, and it shapes future knowledge. However, meta-science research increasingly shows that funding allocation is inherently

How do we arrive at our beliefs? “Neurocomputational mechanisms of affected beliefs” out now!
Affected beliefs Researchers at Lübeck University show links between emotions and the formation of self-efficacy beliefs Why do some people believe that they are good at something and others not, while performing exactly similar? A recent study from Lübeck University, Germany, finds that emotional experiences are linked to the way people establish novel beliefs
Mapping Research Domain Criteria using a transdiagnostic mini-RDoC assessment in mental disorders
New publication with contribution by Annalina V. Mayer! Abstract This study aimed to build on the relationship of well-established self-report and behavioral assessments to the latent constructs positive (PVS) and negative valence systems (NVS), cognitive systems (CS), and social processes (SP) of the Research Domain Criteria (RDoC) framework in a large transnosological population which cuts
