在100日龄的大鼠，其母亲遭受严重缺锌和/或营养不良的整个哺乳期，在两个学习任务进行了测试。一个测试是原始辨别学习任务，另一个测试是更困难的反向辨别学习任务。在反向学习实验中，营养不良康复大鼠和正常大鼠之间的表现有显着差异。动机的差异，而不是学习能力，是营养不良和正常大鼠之间表现差异的解释。
At 100 days of age rats, whose dams suffered severe zinc deficiency and/or undernutrition throughout lactation, were tested in two learning tasks. One test was an original discrimination learning task and the other test was a more difficult reverse discrimination learning task. In the reverse learning test, performance differed significantly between rehabilitated malnourished rats and normal rats. Difference in motivation, and not learning ability, was the explanation for the differences in performance between the malnourished and normal rats.
