Motion sickness is believed to be caused by conflicting sensory signals, a situation that mimics the effects of ingesting certain toxins. Thus, one might suspect that individuals who have experienced a relatively high frequency of motion sickness may be particularly vigilant about avoiding anything that produces nausea, induding potentially nauseating toxins. Consequently, they may be more resistant to trying new foods, i.e., be more food neophobic, since unfamiliar foods can have unexpected adverse effects due to toxins or allergens. Likewise, many highly stimulating experiences can trigger motion sickness, so individuals who are more susceptible may be more prone to avoid such experiences, i.e., be less sensation seeking. Finally, it was expected that food neophobia would be more frequent in individuals low on sensation seeking tendencies. Self-reported motion sickness history in 308 adults (M= 18.8 yr.; SD = 1.6) was correlated with scores on the Arnett Inventory of Sensation Seeking and the Food Neophobia Scale. As predicted, greater history of motion sickness was associated with lower Sensation Seeking scores. Food Neophobia was not correlated with motion sickness history but, as expected, was negatively correlated (r = -.42) with scores on Sensation Seeking. Further research is recommended that measures actual sensitivity to motion sickness.
晕动病被认为是由相互冲突的感官信号引起的，这种情况类似于摄入某些毒素的影响。因此，人们可能会怀疑，经历过相对较高频率晕动病的个体可能会特别警惕避免任何会引起恶心的东西，包括潜在的致呕毒素。因此，他们可能更抗拒尝试新食物，即更有食物新恐惧症，因为不熟悉的食物可能因毒素或过敏原而产生意想不到的不良影响。同样，许多高度刺激的体验会引发晕动病，所以更容易受影响的个体可能更倾向于避免此类体验，即寻求刺激的程度更低。最后，预计在寻求刺激倾向较低的个体中，食物新恐惧症会更常见。对308名成年人（平均年龄M = 18.8岁；标准差SD = 1.6）自我报告的晕动病史与阿尼特寻求刺激量表和食物新恐惧症量表的得分进行了相关性分析。正如预测的那样，晕动病史越长，寻求刺激得分越低。食物新恐惧症与晕动病史没有相关性，但正如预期的那样，与寻求刺激得分呈负相关（r = -0.42）。建议进一步研究测量对晕动病的实际敏感性。
