While compelling illusions of self-motion (vection) can be induced purely by visual motion, they are rarely experienced immediately. This vection onset latency is thought to represent the time required to resolve sensory conflicts between the stationary observer's visual and nonvisual information about self-motion. In this study, we investigated whether manipulations designed to increase the weightings assigned to vision (compared to the nonvisual senses) might reduce vection onset latency. We presented two different types of visual priming displays directly before our main vection-inducing displays: (1) 'random motion' priming displays - designed to pre-activate general, as opposed to self-motion-specific, visual motion processing systems; and (2) 'dynamic no-motion' priming displays - designed to stimulate vision, but not generate conscious motion perceptions. Prior exposure to both types of priming displays was found to significantly shorten vection onset latencies for the main self-motion display. These experiments show that vection onset latencies can be reduced by pre-activating the visual system with both types of priming display. Importantly, these visual priming displays did not need to be capable of inducing vection or conscious motion perception in order to produce such benefits.
虽然纯粹通过视觉运动可以产生令人信服的自我运动错觉（运动错觉），但它们很少立即被体验到。这种运动错觉潜伏期被认为代表了在解决静止观察者的视觉和非视觉关于自我运动的信息之间的感官冲突所需的时间。在这项研究中，我们研究了旨在增加视觉（与非视觉感觉相比）权重的操作是否可能缩短运动错觉潜伏期。我们在主要的运动错觉诱导显示之前呈现了两种不同类型的视觉启动显示：（1）“随机运动”启动显示-旨在预先激活一般的、而不是特定于自我运动的视觉运动处理系统；和（2）“动态无运动”启动显示-旨在刺激视觉，但不能产生有意识的运动感知。先前暴露于这两种类型的启动显示都发现显著缩短了主要自我运动显示的运动错觉潜伏期。这些实验表明，通过用这两种启动显示预先激活视觉系统，可以缩短运动错觉潜伏期。重要的是，这些视觉启动显示不需要能够引起运动错觉或有意识的运动感知，就可以产生这样的好处。
