Surface qualities have little effect on vection strength

Frontiers in Psychology, 2014
We investigated the effects of different surface qualities of materials on vection strength. Previous studies have extensively examined the stimulus parameters for effective vection induction.

Network changes in patients with phobic postural vertigo

Brain and Behavior, Volume 10, Issue 6, June 2020., 2020
Individuals with phobic postural vertigo (PPV) display vestibular symptoms in the absence of a structural or organic origin. For this reason, functional brain mechanisms have been implicated in these disorders. Here, functional network organisation was investigated in PPV patients during functional magnetic resonance imaging with a visual motion ...

Shift in lateralization during illusory self‐motion: EEG responses to visual flicker at 10 Hz and frequency‐specific modulation by tACS

European Journal of Neuroscience, Volume 51, Issue 7, Page 1657-1675, April 2020., 2020
We found hemispheric lateralization in the EEG alpha‐band during illusory self‐movement (vection) induced by large optic flow, supporting the idea of lateralization of visual–vestibular function. Using a novel artefact removal strategy for combined tACS‐EEG, we show that frequency‐matched sawtooth wave tACS significantly enhances SSVEP amplitude; tACS ...

Neural bases of self‐ and object‐motion in a naturalistic vision

Human Brain Mapping, Volume 41, Issue 4, Page 1084-1111, March 2020., 2020
Abstract To plan movements toward objects our brain must recognize whether retinal displacement is due to self‐motion and/or to object‐motion. Here, we aimed to test whether motion areas are able to segregate these types of motion. We combined an event‐related functional magnetic resonance imaging experiment, brain mapping techniques, and wide‐field ...

Too Real to Be Virtual: Autonomic and EEG Responses to Extreme Stress Scenarios in Virtual Reality

Behavioural Neurology, Volume 2020, Issue 1, 2020., 2020
The evolution of virtual reality (VR) technologies requires setting boundaries of its use. In this study, 3 female participants were experiencing VR scenarios with stressful content and their activity of the autonomic nervous system and EEG were recorded.

Vection Is Enhanced by Increased Exposure to Optic Flow

i-Perception, 2018
We examined whether vection strength could be modulated by altering the exposure duration to optic flow. Experiment 1 sourced 150 different video clips from various Japanese animation works which simulated self-motion.

The effect of water immersion on vection in virtual reality

Scientific Reports, 2021
Research about vection (illusory self-motion) has investigated a wide range of sensory cues and employed various methods and equipment, including use of virtual reality (VR).

Vection in virtual environments: psychological and psychophysiological mechanisms [PDF]

Национальный психологический журнал, 2015
The self-motion illusion (‘vection’) refers to a subjective phenomenon where a stationary observer experiences a compelling sense of illusory self-motion when she/he is exposed to large moving patterns of optic flow.

Consistency between Modalities Enhances Visually Induced Self-Motion (Vection)

i-Perception, 2011
Visually induced illusory self-motion (vection) is generally facilitated by consistent information of self-motion from other modalities. We provide three examples that consistent information between vision and other proprioception enhances vection, ie ...

Roles of the Retinotopic and Environmental Frames of Reference on Vection

Frontiers in Virtual Reality, 2020
Humans perceive self-motion using multisensory information, while vision has a dominant role as is utilized in virtual reality (VR) technologies. Previous studies reported that visual motion presented in the lower visual field (LoVF) induces stronger ...
