Abstract The present study investigated the effectiveness of different strategies to increase the willingness to taste, liking and consumption of a disliked vegetable in preschool children, and the moderating role of reward sensitivity. Kindergarten classes (n = 8; preschool children: n = 154, 46,8% boys, age: M = 5.08, SD = 0.61) were assigned to one of four different conditions (i.e. Repeated Neutral Exposure, Repeated Exposure + social reward, Repeated Exposure + token reward and control condition). The results demonstrated that children’s liking and consumption of the disliked vegetable significantly increased in the three active strategies (i.e. consumption and liking increases ranged from 10.1 to 20.6 g, and 34.1 to 51.8% respectively) compared to the control condition (i.e. consumption and liking increases ranged from 0.3 to 1.7 g, and 1.9 to 4.7% respectively). No significant differences were found between the three active strategies for all dependent variables. Little evidence was found for the moderating role of the individual characteristic reward sensitivity.

增加学龄前儿童对蔬菜的喜好和消费的策略:奖励敏感性的作用

摘要 本研究调查了不同策略在增加学龄前儿童对不喜欢的蔬菜的品尝、喜欢和消费意愿的有效性,以及奖励敏感性的调节作用。幼儿园班级(n = 8;学龄前儿童:n = 154,46.8% 男孩,年龄:M = 5.08,SD = 0.61)被分配到四种不同条件之一(即反复中性暴露、反复暴露 + 社会奖励、重复曝光+代币奖励和控制条件)。结果表明,与对照条件(即消耗量和喜欢量增加)相比,三种主动策略(即消耗量和喜欢量增加范围分别为 10.1 至 20.6 g 和 34.1 至 51.8%)中儿童对不喜欢蔬菜的喜欢和消耗量显着增加范围从 0.3 到 1.7 g,和 1。9% 到 4.7%)。对于所有因变量,三种主动策略之间没有发现显着差异。几乎没有证据表明个体特征奖励敏感性的调节作用。
