Effects of Dieting on Neural Encoding of Preferences for Edible and Non-Edible Rewards: An ERP Study

Christina von der Assen, Constanze Weber, Julian Vahedi, Annakarina Mundorf et autres

The present study investigated whether temporary dieting modulates neural coding of subjective preferences for edible and non-edible rewards. Forty-five dieting and 49 non-dieting healthy adults completed a gambling task while EEG was recorded. In each trial, subjects opened virtual doors to receive …

From Feedback‐Learning to Semantic Memory: Can Feedback‐Related Brain Activity Predict Object‐Word Associations?

Christine Albrecht, Laura Bechtold, Marta Ghio, Christian Bellebaum

This study investigated the neural mechanisms underlying feedback-based learning of novel-object-novel-word associations, focusing on how feedback-locked event-related potentials acquired during learning relate to subsequent memory performance and acquired association strength. Specifically, we examined whether amplitudes of the feedback-related negativity (FRN) and N170 …

Experience Matters: Electrophysiological Evidence for Interindividual Differences in Representational Frameworks of Concrete and Abstract Words

Laura Bechtold, Verena Jansen, Christian Bellebaum, Marta Ghio

The differential representational frameworks hypothesis posits that concrete and abstract word processing preferentially rely on similarity-based and associative frameworks, respectively. However, electrophysiological evidence in healthy adults is inconsistent, potentially due to unaccounted interindividual differences in the reliance on these frameworks. We analyzed …

Context-dependent experiential grounding of ambiguous abstract mathematical words

Laura Bechtold, Cristina Cara, Marco Tettamanti, Christian Bellebaum et autres

Grounded cognition accounts posit that the quality and quantity of experience contribute to neural meaning representations, whereas the generalizability of the underlying mechanisms across abstract domains remains debated. Building on initial evidence, this fMRI study further investigated whether abstract mathematical concept processing …

Action or Stimulus: Individual Beliefs About Learned Associations Influence the Processing of Immediate and Delayed Feedback

Christine Albrecht, Marta Ghio, Christian Bellebaum

Feedback learning seems to involve two systems, the striatal reward system and the medial temporal lobe (MTL), which have both been linked to event-related potential (ERP) components such as the feedback-related negativity (FRN)/N2, overlapped by a reward positivity (RewP), and the N170, …

I, You, Robot: Attenuation for auditory outcomes of actions performed by different agents shows distinct patterns for N1 and P2 amplitudes

Sophie Egan, Constanze Weber, Marta Ghio, Christian Bellebaum

Compared to external tones, previous studies found reduced N1 and P2 amplitudes in event-related potentials not only for self-generated tones, referred to as sensory attenuation, but also for tones generated by a person the participant observed. The P2 in this situation was …

Revisiting the link between error significance and the error-related negativity: A multi-lab direct replication

Magdalena Senderecka, Jarosław M. Michałowski, Łukasz Krzywoszański, Christian Bellebaum et autres

Error monitoring is a key cognitive control process that enables individuals to evaluate their actions and detect failures in goal-directed behavior. A well-established neural correlate of error monitoring is the error-related negativity (ERN), an event-related potential that emerges within 100 ms of …

Links Between Altered Feedback Learning and Symptoms of Depression: Insights From the FRN and Feedback‐Locked N170

Madita Röhlinger, Julian Vahedi, Christian Bellebaum

Blunted electrophysiological and striatal responses to reward have been suggested as biomarkers or endophenotypes for depression. However, previous studies did not differentiate between learning from immediate and learning from delayed feedback, which involves different neural structures. The aim of the present study …
