EEG decodability of facial expressions and their stereoscopic depth cues in immersive virtual reality Open
Face perception typically occurs in three-dimensional space, where stereoscopic depth cues enrich the perception of facial features. Yet, most neurophysiological research on face processing relies on two-dimensional displays, potentially o…

Dynamic presentation in 3D modulates face similarity judgments – A human-aligned encoding model approach Open
Face perception dynamically unfolds in three-dimensional space, yet, experimental paradigms predominantly rely on static 2D images, limiting insights into real-world face processing. We conducted a pre-registered study comparing face simil…

Infants in Control—Evidence for Agency in 6‐ to 10‐Months‐Old Infants in a Gaze‐Contingent Eye Tracking Paradigm Open
The ability to control movement is a core element of agency. Previous studies of infant agency have focused on responses to sensory contingencies but neglected the importance of infants' control as a necessary indicator of agency. Here, we…

Geometry matters: insights from Ollivier Ricci Curvature and Ricci Flow into representational alignment through Ollivier-Ricci Curvature and Ricci Flow Open
Representational similarity analysis (RSA) is widely used to analyze the alignment between humans and neural networks; however, conclusions based on this approach can be misleading without considering the underlying representational geomet…

The utility of explainable AI for MRI analysis: Relating model predictions to neuroimaging features of the aging brain Open
Deep learning models highly accurately predict brain age from MRI but their explanatory capacity is limited. Explainable artificial intelligence (XAI) methods can identify relevant voxels contributing to model estimates, yet they do not re…

Linking brain–heart interactions to emotional arousal in immersive virtual reality Open
The subjective experience of emotions is linked to the contextualized perception and appraisal of changes in bodily (e.g., heart) activity. Increased emotional arousal has been related to attenuated high‐frequency heart rate variability (H…

Human-aligned deep and sparse encoding models of dynamic 3D face similarity perception Open
Face perception happens dynamically over time and primarily in three-dimensional space. Perceived similarity, including identity, should ideally remain invariant to changes along these dimensions. Surprisingly, much of our knowledge about …

Revealing the Learning Process in Reinforcement Learning Agents Through Attention-Oriented Metrics Open
The learning process of a reinforcement learning (RL) agent remains poorly understood beyond the mathematical formulation of its learning algorithm. To address this gap, we introduce attention-oriented metrics (ATOMs) to investigate the de…

Pre-stimulus beta power mediates explicit and implicit perceptual biases in distinct cortical areas Open
Perception is biased by expectations and previous actions. Pre-stimulus brain oscillations are a potential candidate for implementing biases in the brain. In two EEG studies (43 and 39 participants) on somatosensory near-threshold detectio…

Decoding the neural representations of emotional faces in stereo- versus monoscopic viewing conditions Open
Humans represent faces as three-dimensional shapes and facial expressions as changes in the spatial configuration of relevant landmarks (e.g., eyebrows) in them. Stereopsis is a key component of the visual system for perceiving spatial dep…
