It was examined whether caloric conditioning or social learning strategies dominate in taste preference acquisition in children. The caloric learning paradigm predicts that eating or drinking artificially sweetened products, which deliver virtually no energy, will not lead to a taste preference whereas the social learning paradigm predicts that seeing important others modelling the eating and drinking of these 'light' products will induce a preference for the taste of light products in the child.
In a 2 x 2 between subjects factorial design, the amount of energy and social modelling was varied.
The study was undertaken at primary schools in Maastricht, The Netherlands.
Forty-five children participated and six children dropped out. The 39 children who completed the study (14 boys and 25 girls) had a mean age of 67 months (range 51--81, s.d. 5.6).
Each subject took part in nine conditioning trials with an individually selected tasting yoghurt which was not preferred very much at the pre-test.
The children in the combined caloric and social condition showed an increase in their preference for the conditioned taste which was larger than a regression-to-the-mean effect (P=0.007), whereas children in the other groups did not.
Caloric and social learning combined, ie modelling the consumption of energy-rich foods or drinks, is the best way to establish taste preferences. Children more easily learn a preference for energy-rich food that is eaten by significant others than for food that is low in energy and eaten by significant others.
研究热量条件作用或社会学习策略在儿童味觉偏好形成过程中何者占主导地位。热量学习范式预测,食用或饮用几乎不提供能量的人工甜味产品不会导致味觉偏好,而社会学习范式预测,看到重要他人对这些“低热量”产品的饮食行为进行示范,会使儿童对低热量产品的味道产生偏好。
采用2×2被试间析因设计,改变能量和社会示范的量。
该研究在荷兰马斯特里赫特的小学进行。
45名儿童参与研究,6名儿童退出。完成研究的39名儿童(14名男孩和25名女孩)平均年龄为67个月(范围51 - 81个月,标准差5.6)。
每个受试者参与9次条件作用试验,使用一种在预测试中不太受青睐的、为其单独挑选的品尝酸奶。
热量和社会条件相结合组的儿童对条件化味道的偏好增加,且大于均值回归效应(P = 0.007),而其他组儿童则没有。
热量学习与社会学习相结合,即对富含能量的食物或饮料的消费进行示范,是建立味觉偏好的最佳方式。与低能量且被重要他人食用的食物相比,儿童更容易对被重要他人食用的富含能量的食物产生偏好。
