51 subjects were divided into Familiar- and Unfamiliar-drink groups based on whether they had tasted soybean milk before the experiment. Each subject then viewed an optokinetic rotating drum for 10 min. Subjective assessments of nausea and over-all symptoms of motion sickness were measured during the drum rotation. Two hours later subjects drank the soybean milk again. The consumed volume and rating of likeableness of the drink were subsequently measured. Analysis showed that the subjects in the Unfamiliar-drink group reported significantly higher taste aversion and consumed significantly less soybean milk after rotation than those in the Familiar-drink group. Correlation for the Unfamiliar-drink group indicated that the rated taste aversion was positively correlated with ratings of over-all symptoms of motion sickness and that the consumed volume of soybean milk was negatively correlated with ratings of over-all symptoms of motion sickness. We concluded that the magnitude of acquired conditioned taste aversion was dependent upon the severity of over-all symptoms of visually induced motion sickness when subjects were unfamiliar with the flavor of the target drink.
51名受试者根据实验前是否尝过豆浆被分为熟悉饮品组和不熟悉饮品组。然后，每位受试者观看视动旋转鼓10分钟。在鼓旋转期间测量恶心和晕动病总体症状的主观评估。两小时后，受试者再次饮用豆浆。随后测量饮品的饮用量和喜爱程度评分。分析表明，与熟悉饮品组相比，不熟悉饮品组的受试者在旋转后报告的味觉厌恶明显更高，饮用的豆浆量明显更少。不熟悉饮品组的相关性表明，味觉厌恶评分与晕动病总体症状评分呈正相关，豆浆饮用量与晕动病总体症状评分呈负相关。我们得出结论，当受试者不熟悉目标饮品的味道时，获得性条件性味觉厌恶的程度取决于视觉诱发晕动病总体症状的严重程度。
