Researchers have identified an unbalanced diet as a key risk factor in the etiology of many chronic diseases (World Health Organization, ). Although researchers have found that numerous factors influence children's food choices, no assessment exists to identify these factors. In Experiment 1, we established preliminary empirical evidence of children's preferences for healthier and less-healthy foods, and found that 16 of 21 children preferred less-healthy foods to healthier foods. In Experiment 2, we established the utility of an analogue, competing parameters assessment designed to approximate children's food choices in the natural environment. We identified either quality or immediacy as the most influential parameters governing four of four childrens' food choices. We found that effort influenced the efficacy of these reinforcer parameters in a predictable manner for one of four children.
研究人员已经确定，饮食不均衡是许多慢性疾病病因的一个关键风险因素（世界卫生组织，）。尽管研究人员发现许多因素会影响儿童的食物选择，但目前还没有评估这些因素的方法。在实验 1 中，我们初步获得了儿童对更健康和不太健康食物的偏好的经验证据，发现 21 名儿童中有 16 名更喜欢不太健康的食物而不是更健康的食物。在实验 2 中，我们建立了一种类似的、竞争参数评估的有效性，该评估旨在模拟儿童在自然环境中的食物选择。我们确定了质量或即时性是四个儿童的食物选择的四个最有影响力的参数。我们发现，对于四个孩子中的一个，努力以可预测的方式影响这些强化参数的效果。
