استراتژی های افزایش میل جنسی و مصرف سبزیجات کودک پیش دبستانی: نقش حساسیت پاداش

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.
