Acceptance of and expressed preference for varying levels of salt (NaCl) were assessed among children 3-6 years of age. 20 children received 0, 0.17, and 0.34 M NaCl in aqueous solution, and 20 received these same NaCl concentrations in a soup broth. In both groups, children were asked to ingest as much as they wanted to each stimulus during brief, sequential presentations and to indicate which stimulus they preferred in a series of paired-comparison presentations. A striking, context-specific reaction to the taste of salt was observed on both measures. Children in this age group strongly rejected even the moderate level of salt in water relative to unsalted water. In contrast, the most highly salted soup was well accepted and preferred to either unsalted or moderately salted soup by the majority of children.
对3至6岁儿童对不同盐(氯化钠)水平的接受度和表达出的偏好进行了评估。20名儿童分别接受了浓度为0、0.17和0.34M的氯化钠水溶液,另外20名儿童接受了相同氯化钠浓度的汤液。在两组实验中,要求儿童在简短、连续的展示过程中根据自身意愿摄入每种刺激物,并在一系列成对比较展示中指出他们更喜欢哪种刺激物。在这两项测量中均观察到对盐味的显著的、特定情境的反应。相对于无盐的水,这个年龄组的儿童甚至强烈拒绝水中适度的盐含量。相比之下,大多数儿童很好地接受了含盐量最高的汤,并且比起无盐或含盐量适中的汤,他们更喜欢这种汤。
