在虚拟环境中的晕动病体验可以通过实验前和实验后的自我报告问卷来测量，如模拟器疾病问卷(SSQ)。尽管研究提供了一致的证据，表明虚拟环境的用户会经历晕动病，但还没有对照研究来确定用户的主观反应在多大程度上是由测试前和测试后的措施产生的需求特征。在这项研究中，受试者被给予SSQ的虚拟前和虚拟后环境沉浸，或仅给予刺激后沉浸。这项技术测试了对比效果，这是由于需求特征，在这种需求特征中，问卷本身的管理向参与者表明，虚拟环境可能会产生晕动病。结果表明，与只使用测试后问卷相比，同时提供前后调查问卷时，沉浸在虚拟环境中后晕车的报告要多得多。讨论了虚拟环境中晕动病评估的意义。
The experience of motion sickness in a virtual environment may be measured through pre and postexperiment self-reported questionnaires such as the Simulator Sickness Questionnaire (SSQ). Although research provides converging evidence that users of virtual environments can experience motion sickness, there have been no controlled studies to determine to what extent the user's subjective response is a demand characteristic resulting from pre and posttest measures. In this study, subjects were given either SSQ's both pre and postvirtual environment immersion, or only postimmersion. This technique tested for contrast effects due to demand characteristics in which administration of the questionnaire itself suggested to the participant that the virtual environment may produce motion sickness. Results indicate that reports of motion sickness after immersion in a virtual environment are much greater when both pre and postquestionnaires are given than when only a posttest questionnaire is used. The implications for assessments of motion sickness in virtual environments are discussed.
