Twenty-two adult participants, assigned to three conditions, were trained nutrition knowledge (i.e., carbohydrate values) for different food items. In a stimulus sorting test, the participants were asked to sort stimuli (names of food items) into one of three different ranges of carbohydrate values ("less than 20", "20–40", "more than 40" gram per 100 gram). Conditional-discrimination training and testing followed the sorting test, and finally, a postclass formation sorting test of the stimuli used in the conditional-discrimination training. The conditional-discrimination training used tailored stimuli, that is, the food items that each of the participants categorized incorrectly in the sorting test. Participants exposed to Conditions 1 and 2 were trained on six conditional discriminations and tested for the formation of three 3-member classes. Conditions 2 and 3 had a “don’t know” option together with the three different ranges of carbohydrate values in the sorting for tailoring the stimuli. Participants exposed to Condition 3 trained were trained on 12 conditional discriminations and tested for the formation of three 5-member classes. The main findings showed that all but one of the participants responded correctly on at least one test for equivalence class formation and sorted the stimuli correctly in the postclass formation sorting test.

使用等效刺激技术教授有关营养成分的技能

22名成年参与者被分配给三种情况，他们接受了针对不同食品的营养知识（即碳水化合物值）培训。在刺激性分类测试中，要求参与者将刺激物（食品名称）分类为三个不同范围的碳水化合物值之一（每100克“小于20”，“ 20-40”，“大于40”克） ）。有条件歧视培训和测试遵循了分类测试，最后是有条件歧视培训中使用的刺激的课后形成分类测试。有条件的歧视训练使用了定制的刺激，即每个参与者在分类测试中错误分类的食物。暴露于条件1和2的参与者接受了六种条件歧视的培训，并测试了三个三人班级的形成。条件2和3具有“不知道”选项，并在分类中针对刺激定制了三种不同的碳水化合物值范围。接受条件3培训的参与者接受了12种条件歧视的培训，并测试了三个5人班级的形成。主要发现表明，除一名参与者外，所有参与者均至少对一项等效类形成测试做出了正确反应，并在课后形成分类测试中对刺激进行了正确分类。接受条件3培训的参与者接受了12种条件歧视的培训，并测试了三个5人班级的形成。主要发现表明，除一名参与者外，所有参与者均至少对一项等效类形成测试做出了正确反应，并在课后形成分类测试中对刺激进行了正确分类。接受条件3培训的参与者接受了12种条件歧视的培训，并测试了三个5人班级的形成。主要发现表明，除一名参与者外，所有参与者均至少对一项等效类形成测试做出了正确反应，并在课后形成分类测试中对刺激进行了正确分类。
