Abstract

An important aspect to an immersive experience in Virtual Reality is vection, defined as the illusion of self-motion. Much of the literature to date has explored strategies to maximize vection through manipulations of the visual stimulus (e.g., increasing speed) or the experimental context (e.g., framing of the study instructions). However, the role of individual differences (e.g., age, biological sex) in vection susceptibility has received little attention. The objective of the current study was to investigate the influence of individual-difference factors on vection perception in younger and older adults. Forty-six younger adults (M age = 25.1) and 39 older adults (M age = 72.4) completed assessments of personality traits, field dependence, and visual attention prior to observing a moving visual stimulus aimed at inducing circular vection. Vection was measured using self-reports of onset latency, duration, and intensity. Results indicated that, in both age groups, females experienced longer-lasting vection compared to males. Additionally, the level of field dependence was related to vection intensity and duration in males but not in females. Variability in vection intensity was best explained by a mixture of biological, perceptual, cognitive, and personality variables. Taken together, these findings suggest that individual factors are important for understanding differences in vection susceptibility.

年轻人和老年人的个体因素和视线:性别、场地依赖性、性格和视觉注意力如何影响(或不影响)幻觉自我运动。
虚拟现实沉浸式体验的一个重要方面是矢量,即自我运动的错觉。迄今为止,许多文献都在探讨通过操纵视觉刺激(如提高速度)或实验环境(如研究说明的框架)来最大限度地提高牵引力的策略。然而,个体差异(如年龄、生理性别)在静脉曲张易感性中的作用却很少受到关注。本研究的目的是调查个体差异因素对年轻和年长成年人静脉注射感知的影响。46 名年轻人(平均年龄为 25.1 岁)和 39 名老年人(平均年龄为 72.4 岁)在观察旨在诱发圆形脉动的移动视觉刺激物之前完成了人格特质、视野依赖性和视觉注意力的评估。通过对起始潜伏期、持续时间和强度的自我报告来测量脉动。结果表明,与男性相比,两个年龄组的女性都会出现持续时间更长的牵引。此外,在男性中,场依赖程度与脉动强度和持续时间有关,而在女性中则无关。生物、知觉、认知和个性变量的混合体最能解释脉动强度的变化。综上所述,这些研究结果表明,个体因素对于理解静脉曲张易感性的差异非常重要。
