据报道，有两个实验表明，大鼠能够在溶液中存在铁(当它不是特别需要的时候)和随后的缺铁状态之间形成联系。具体地说，老鼠被训练在口渴时撬动压力机获取水。其中一组除了喝水外，还接受了亚铁离子。当这些大鼠随后被造成铁缺乏时，它们在消亡条件下受到的杠杆压力更大，这是较低血红蛋白水平的分级功能。对照组在训练期间没有接受亚铁离子，或者在训练期间接受了除亚铁溶液以外的溶液，在灭绝条件下没有这种反应。因此，这是一种潜伏性学习，以前只证明了钠的食欲。
Two experiments are reported which show that rats are capable of forming an association between the presence of iron in a solution when it is not specifically needed and a subsequent state of iron deficiency. Specifically, rats were trained to lever press for water while thirsty. One group received ferrous ions in addition to the water. When these rats were subsequently rendered iron deficient, they lever pressed more under extinction conditions as a graded function of lower hemoglobin levels. Controls that either did not receive ferrous ions during training or received solutions other than ferrous solutions during training did not respond this way under extinction conditions. This is therefore a type of latent learning previously demonstrated only for sodium appetite.
