We examined the effects of manipulated arousal on willingness to taste moderately novel and extremely novel foods in children ranging from 7 to 12 years of age. Children were assigned at random to one of three arousal conditions (low, moderate, and high). Twice during the 30-min manipulation period, the children rated their willingness to taste the foods, with the understanding that these ratings would be used to determine which foods they would taste later in the session. Results of an Age x Gender x Arousal condition analysis on willingness to try the novel foods revealed a significant effect of arousal condition; willingness increased with decreasing arousal. Separate analyses for the moderately and extremely novel foods yielded significant condition and age effects for the former and no significant effects for the latter. The results were discussed in the context of optimal level of arousal theories.
我们研究了对7至12岁儿童进行不同程度唤醒操作后，其对适度新奇和极度新奇食物的品尝意愿的影响。儿童被随机分配到三种唤醒条件（低、中、高）之一。在30分钟的操作期内，儿童两次对品尝食物的意愿进行评分，并了解这些评分将用于确定他们在该环节稍后会品尝哪些食物。对尝试新奇食物意愿的年龄×性别×唤醒条件分析结果显示，唤醒条件有显著影响；随着唤醒程度降低，意愿增加。对适度新奇和极度新奇食物的单独分析表明，前者有显著的条件和年龄效应，而后者则无显著效应。研究结果在唤醒理论的最佳水平背景下进行了讨论。
