Post-COVID syndrome (PCS) describes a persistent complex of symptoms following a COVID-19 episode, lasting at least 4 to 12 weeks, depending on the specific criteria used for its definition. It is often associated with moderate to severe impairments of daily life and represents a major burden for many people worldwide. However, especially during th...

Background: Depression and fatigue are commonly observed sequelae following viral diseases such as COVID-19. Identifying symptom constellations that differentially classify post-COVID depression and fatigue may be helpful to individualize treatment strategies. Here, we investigated whether self-reported post-COVID depression and post-COVID fatigue...

This study investigates the sense of agency (SoA) for saccades with implicit and explicit agency measures. In two eye tracking experiments, participants moved their eyes towards on-screen stimuli that subsequently changed color. Participants then either reproduced the temporal interval between saccade and color-change (Experiment 1) or reported the...

When a single action is required, along with the simultaneous inhibition of another action, this typically results in frequent false-positive executions of the latter (inhibition failures). The absence of inhibitory demands in dual-action trials can render performance less error-prone (and sometimes faster) than in single-action trials. In the pres...

Sense of agency (SoA) is the feeling of having control over one's actions and their outcomes. Previous research claimed that SoA is reflected in "intentional binding" effects, that is, the subjective compression of time between a voluntary action and an intended outcome. Conventional paradigms, however, typically lack an isolated manipulation of di...

Previous research has shown that the simultaneous execution of two actions (instead of only one) is not necessarily more difficult but can actually be easier (less error-prone), in particular when executing one action requires the simultaneous inhibition of another action. Corresponding inhibitory demands are particularly challenging when the to-be...

Emojis are nowadays a common substitute for real facial expressions to integrate emotions in social interaction. In certain contexts, emojis possibly could also transport information beyond emotions, reflecting interindividual differences or social aspects. In this study, we investigated the influence of emojis as socioemotional feedback stimuli on...

Tactile event-related potential (ERP) controlled brain-computer-interfaces (BCI) are rarely used as input signal due to their low accuracy and speed (information transfer rate, ITR). Age-related loss of tactile sensibility might further decrease their viability for the target population of BCI. In this study we investigated whether training improve...
