Action Video Game Players Do Not Differ in the Perception of Contrast-Based Motion Illusions but Experience More Vection and Less Discomfort in a Virtual Environment Compared to Non-Action Video Game Players

Abstract

Action video game players (AVGPs) show enhanced visual perceptual functions compared to their non-video game playing peers (NVGPs). Whether AVGPs are more susceptible towards static contrast motion illusions, such as Fraser Wilcox illusions, has not been addressed so far. Based on their improved perceptual skills, AVGPs are expected to be more susceptible to the illusions and perceive more motion in them. The experience of illusory self-motion (vection) is believed to be dependent on top-down attentional processes; AVGPs should therefore experience stronger vection compared to NVGPs based on their improved attentional skills. Lastly, due to their extensive prior experience with virtual environments, AVGPs should experience less discomfort in VR compared to NVGPs. We presented rotating and expanding motion illusions in a virtual environment and asked 22 AVGPs and 21 NVGPs to indicate the strength of illusory motion, as well as the level of discomfort and vection experienced when exposed to these motion illusions. Results indicated that AVGPs and NVGPs perceived the same amount of motion when viewing these illusions. However, AVGPs perceived more vection and less discomfort compared to NVGPs, possibly due to factors such as enhanced top-down attentional control and adaptation. No differences in the perception of expanding and rotating illusions were found. Discomfort experienced by AVGPs was related to illusion strength, suggesting that contrast illusions might evoke the perceived discomfort rather than the virtual environment. Further studies are required to investigate the relationship between contrast sensitivity, migraine and the perception of illusion in AVGPs which should include illusory motion onset and duration measures.

Measurement of craving among gamers with internet gaming disorder using repeated presentations of game videos: a resting-state electroencephalography study

“…Therefore, this inter-participant difference from the VR-effect might be low. Although some participants could adapt to VR better than others, Pöhlmann et al [ 97 ] reported that the discomfort from VR caused different effects such as illusion strength. This point is known to cause inter-participant differences according to degree of discomfort [ 97 ].…”

Can Gender and Motion Sickness Susceptibility Predict Cybersickness in VR ?

“…Time spent playing video games has also been shown to impact users susceptibility to cybersickness, with individuals that classify as gamers, someone that has spend extensive time playing video games in the past, often experiencing weaker and less sickness symptoms when immersed in HMDs or other more sickness inducing virtual environments (e.g., driving simulators, etc.) [21,37,38,47]. These beneficial effects have been found for both male and female participants with some work [38] even suggesting that these effects might be more pronounced for females rather than males.…”

VR Sickness Adaptation With Ramped Optic Flow Transfers From Abstract To Realistic Environments

“…Similarly, an experiment by Mouloua et al (2005) demonstrated cross-platform training was possible, but that it was only successful when using optokinetic nystagmus (OKN) training, and not a VR HMD ( Mouloua et al, 2005 ). Another study by Pöhlmann and colleagues (2021) found that individuals that spend extensive amounts of time playing action video games (not on HMDs) experienced less VR sickness when exposed to a simple virtual environment compared to individuals that do not play any video games ( Pöhlmann et al, 2021 ). All of these experiments were examining transfer in a way that used a non-VR device as their training mechanism.…”
