The traditional two-pan choice test and an operant lever-press choice test were used to assess dogs' preferences between various foods. In the first two experiments the foods differed in flavor as manipulated by the amount of fat-coating added to a dry-food base. In the third experiment, the foods were commercially-available dry and semi-moist dog foods. The experiments illustrate that preference data obtained with these two test methodologies do not always point to the same conclusion, and that complexities are involved in predicting the outcome of a preference test from performance on previous tests.
传统的双盘选择测试和操作性杠杆按压选择测试被用于评估狗对各种食物的偏好。在前两个实验中，通过在干粮基础上添加不同量的脂肪涂层来改变食物的风味。在第三个实验中，使用的是市售的干粮和半湿狗粮。这些实验表明，用这两种测试方法获得的偏好数据并不总是指向相同的结论，而且从之前测试的表现来预测偏好测试的结果存在复杂性。
