The present research focuses on the effectiveness of visual exposure to vegetables in reducing food neophobia and pickiness among young children. We tested the hypotheses that (1) simple visual exposure to vegetables leads to an increase in the consumption of this food category, (2) diverse visual exposure to vegetables (i.e., vegetables varying in color are shown to children) leads to a greater increase in the consumption of this food category than classical exposure paradigms (i.e. the same mode of presentation of a given food across exposure sessions) and (3) visual exposure to vegetables leads to an increase in the consumption of this food category through a mediating effect of an increase in ease of categorization. We recruited 70 children aged 3-6 years who performed a 4-week study consisting of three phases: a 2-week visual exposure phase where place mats with pictures of vegetables were set on tables in school cafeterias, and pre and post intervention phases where willingness to try vegetables as well as cognitive performances were assessed for each child. Results indicated that visual exposure led to an increased consumption of exposed and non-exposed vegetables after the intervention period. Nevertheless, the exposure intervention where vegetables varying in color were shown to children was no more effective. Finally, results showed that an ease of categorization led to a larger impact after the exposure manipulation. The findings suggest that vegetable pictures might help parents to deal with some of the difficulties associated with the introduction of novel vegetables and furthermore that focusing on conceptual development could be an efficient way to tackle food neophobia and pickiness.
本研究关注的是视觉接触蔬菜对减少幼儿食物恐惧症和挑食的有效性。我们检验了以下假设：(1) 简单的视觉接触蔬菜会导致对这类食物的消费增加；(2) 多样化的视觉接触蔬菜（即向儿童展示不同颜色的蔬菜）比传统的暴露范式（即同一食物在不同暴露阶段的呈现方式相同）更能增加对这类食物的消费；(3) 视觉接触蔬菜会通过增加分类的容易程度来增加对这种食物的消费。我们招募了 70 名 3-6 岁的儿童，他们进行了为期 4 周的研究，包括三个阶段：为期 2 周的视觉暴露阶段，学校自助餐厅的桌子上放置了带有蔬菜图片的餐垫；干预前和干预后阶段，对每个孩子的尝试蔬菜的意愿以及认知表现进行评估。结果表明，视觉接触导致干预后暴露和未暴露的蔬菜消费增加。然而，向儿童展示颜色各异的蔬菜的暴露干预效果并不显著。最后，结果表明，在暴露操作后，分类的容易程度产生了更大的影响。研究结果表明，蔬菜图片可能有助于父母应对与引入新蔬菜相关的一些困难，此外，关注概念发展可能是解决食物恐惧症和挑食的有效方法。
