In the current study, we examined the role of expectancy violation and retrospective reasoning about the absence of feared outcomes in virtual reality exposure therapy (VRET). Participants fearful of public speaking were asked to give speeches in virtual reality. We asked each participant individually to report their expectancies about feared outcomes in public speaking situations and which of these could be tested in VRET. Each of the ...

Introduction: Mental fatigue has been shown to negatively affect motor and sport performance. To date, however, no research focused on assessing the effects of mental fatigue on hazard perception in young cyclists who are highly vulnerable in traffic, especially after school. Therefore, the purpose of this study was to examine the influence of induced mental fatigue on hazard perception and anticipation in young cyclists using a novel Virtual ...

Virtual Reality has spent the recent years stuck between grand promises and sceptical eye rolls. When I began this research, VR was still striving to prove its value, more than half a century after the Sensorama Simulator, it remained uncertain whether VR would become the future of digital interaction or fade as another overhyped gimmick. Instead of getting caught in this debate, I wanted to explore what VR feels like, how people experience it, ...

The development of immersive technologies has brought with it the need to redefine the concept of quality of experience (QoE). Studies have explored QoE in virtual reality (VR) by adopting a top-down approach—these are solely based on existing frameworks and theory and complemented with novel technical considerations. It can be argued that any QoE framework derived in this manner is limited, as its scope is fixed even prior to any data gathering ...

While virtual reality exposure (VRE) has shown effectiveness in treating social anxiety in adults, research on its efficacy for adolescents remains limited. Given that adolescence is a critical period for early intervention, this study aims to address this gap by evaluating the efficacy and acceptability of VRE compared to in vivo exposure (IVE) in a non-referred sample of socially anxious adolescents. Additionally, we seek to identify ...

Perception in virtual reality is often compared to the perception of pictures. there are, however, important differences. A virtual reality environment, unlike a picture, is interactive and immersive. these properties give rise to novel theoretical challenges. Building on James J. Gibson’s analysis of the perception of depictions, we raise three questions about perception in virtual reality, to which we offer tenta- tive answers: (1) Is virtual ...

The omnidirectional nature of Virtual Reality (VR) content provides an immersive experience for the viewer. At the same time, VR content relies heavily on the quality of the video to deliver an immersive experience. This study investigates the effect of video quality degradation on aspects of the viewer's quality of experience (QoE) via subjective (i.e., a questionnaire) and objective (i.e., electroencephalogram) methods. We measured the ...

Lifting an object requires precise scaling of fingertip forces based on a prediction of object weight. At object contact, a series of tactile and visual events arise that need to be rapidly processed online to fine-tune the planned motor commands for lifting the object. The brain mechanisms underlying multisensory integration serially at transient sensorimotor events, a general feature of actions requiring hand-object interactions, are not yet ...

Visuospatial neglect (VSN) is a common post-stroke disorder characterized by impaired attention toward the contralesional hemispace, affecting interaction with the environment. Traditional assessments (e.g., pen-and-paper tests) may not detect subtle deficits in visual search behaviour, particularly in complex, dynamic settings. This study introduces an immersive virtual reality (VR) visual search task designed to assess visual search behaviour ...
