Electrophysiological research with event-related brain potentials (ERPs) is increasingly moving from simple, strictly orthogonal stimulation paradigms towards more complex, quasi-experimental designs and naturalistic situations that involve fast, multisensory complex motor behavior. As a result, electrophysiological responses subsequent events often overlap each other. In addition, the recorded neural activity typically modulated by numerous covariates, which influence measured in linear or...
In everyday life, spatial navigation involving locomotion provides congruent visual, vestibular, and kinesthetic information that need to be integrated. Yet, previous studies on human brain activity during focus stationary setups, neglecting vestibular feedback. The aim of our work is uncover the influence those sensory modalities cortical processing. We developed a fully immersive virtual reality setup combined with high-density mobile electroencephalography (EEG). Participants traversed...
Eye-tracking experiments rely heavily on good data quality of eye-trackers. Unfortunately, it is often the case that only spatial accuracy and precision values are available from manufacturers. These two alone not sufficient to serve as a benchmark for an eye-tracker: deteriorates during experimental session due head movements, changing illumination or calibration decay. Additionally, different paradigms require analysis types eye movements; instance, smooth pursuit blinks microsaccades,...
There is growing awareness across the neuroscience community that replicability of findings about relationship between brain activity and cognitive phenomena can be improved by conducting studies with high statistical power adhere to well-defined standardised analysis pipelines. Inspired recent efforts from psychological sciences, desire examine some foundational using electroencephalography (EEG), we have launched #EEGManyLabs, a large-scale international collaborative replication effort....
Fixation-related potentials (FRPs), neural responses aligned to the end of saccades, are a promising tool for studying dynamics attention and cognition under natural viewing conditions. In past, four methodological problems have complicated analysis such combined eye-tracking/electroencephalogram experiments: (1) synchronization data streams, (2) removal ocular artifacts, (3) condition-specific temporal overlap between brain evoked by consecutive fixations, (4) fact that numerous low-level...
Humans often evaluate sensory signals according to their reliability for optimal decision-making. However, how do we percepts generated in the absence of direct input that are, therefore, completely unreliable? Here, utilize phenomenon filling-in occurring at physiological blind-spots compare partially inferred and veridical percepts. Subjects chose between stimuli elicit filling-in, perceptually equivalent ones presented outside blind-spots, looking a Gabor stimulus without small orthogonal...
Eye movement research is a highly active and productive field. Here we focus on how the embodied nature of eye movements can act as window to brain mind. In particular, discuss conscious perception depends trajectory fixated locations consequently address fixation are selected. Specifically, argue that selection points during visual exploration be understood large degree based retinotopically structured models. Yet, these models largely ignore spatiotemporal structure in eye-movement...
Perceptual decisions are biased toward previous decisions. Earlier research suggests that this choice repetition bias is increased after of high confidence, as inferred from response time measures (Urai, Braun, & Donner, 2017), but also when were based on weak sensory evidence (Akaishi, Umeda, Nagase, Sakai, 2014). As typically associated with low these findings appear conflicting. To resolve conflict, we set out to investigate the effect decision confidence more directly by measuring...
Cognitive-behavioural theories propose that attentional biases contribute to the development and maintenance of obsessive-compulsive disorder (OCD). However, research findings have been inconsistent, with some studies supporting vigilance (i.e., rapid orientation toward threatening material) and/or difficulty disengaging from material), others showing either one or neither these biases. These inconsistencies may be related several limitations previous (e.g., no clinical control groups, focus...
The brain is proposed to operate through probabilistic inference, testing and refining predictions about the world. Here, we search for neural activity compatible with violation of active predictions, learned from contingencies between actions consequent changes in sensory input. We focused on vision, where eye movements produce stimuli shifts that could, principle, be predicted. compared, humans, error signals saccade-contingent veridical inferred inputs by contrasting...
Abstract Adaptive visualization and interfaces pervade our everyday tasks to improve interaction from the point of view user performance experience. This approach allows using several inputs, whether physiological, behavioral, qualitative, or multimodal combinations, enhance interaction. Due multitude approaches, we outline current research trends inputs used adapt visualizations interfaces. Moreover, discuss methodological approaches in mixed reality, physiological computing, visual...

This preregistration template guides researchers who wish to preregister their EEG projects, more specifically studies investigating event-related potentials (ERPs) in the sensor space.
Neural mechanisms of face perception are predominantly studied in well-controlled experimental settings that involve random stimulus sequences and fixed eye positions. Although powerful, the employed paradigms far from what constitutes natural vision. Here, we demonstrate feasibility ecologically more valid using viewing behaviour, by combining a free paradigm on scenes, photographer bias, with advanced data processing techniques correct for overlap effects co-varying non-linear dependencies...

Electroencephalography (EEG) and event-related potentials (ERPs) have been analyzed for more than 70 years. Yet, we know little about how practitioners visualize the results of their analyses. Here, designed an online survey (n=213) targeting M/EEG from novice to expert level. Our primary goal is better understand visualization tools currently in use, challenges researchers face, experiences opinions on best display brain data. Finally, explored whether are aware general issues related...
ABSTRACT Fixation-related potentials (FRPs), neural responses aligned to saccade offsets, are a promising tool study the dynamics of attention and cognition under natural viewing conditions.

The question of how self-driving cars should behave in dilemma situations has recently attracted a lot attention science, media and society. A growing number publications amass insight into the factors underlying choices we make such situations, often using forced-choice paradigms closely linked to trolley dilemma. methodology used address these questions, however, varies widely between studies, ranging from fully immersive virtual reality settings completely text-based surveys. In this...
Prediction in language has traditionally been studied using simple designs which neural responses to expected and unexpected words are compared a categorical fashion. However, these have contested as being `prediction encouraging', potentially exaggerating the importance of prediction understanding. A few recent studies begun address worries by model-based approaches probe effects linguistic predictability naturalistic stimuli (e.g. continuous narrative). so far only looked at very local...
When scanning a visual scene, we are in constant decision process regarding whether to further exploit the information content at current fixation or go on and explore scene. The balance of these two processes determines distribution durations. Using gaze-contingent paradigm, experimentally interrupt this probe its state. Here, developed guided-viewing task where only single 3° aperture an image ("bubble") is displayed. Subjects had fixate bubble for controlled time (forced time). Then,...
Humans achieve their goals in joint action tasks either by cooperation or competition. In the present study, we investigated neural processes underpinning error and monetary rewards processing such cooperative competitive situations. We used electroencephalography (EEG) analyzed event-related potentials (ERPs) triggered feedback both social 26 dyads performed a four-alternative forced choice (4AFC) visual task cooperatively competitively. At end of each trial, participants received...
