Conditioned inhibition or CI training (A+/AB-) was compared with S- training (A+/B-) in three experiments on proboscis-extension conditioning in harnessed honeybees. The purpose was to test the Rescorla-Wagner assumption, widely credited in the vertebrate literature, that a nonreinforced stimulus acquires inhibitory properties in proportion to the excitatory value of the context in which it is presented. In prior work with free-flying honeybees pretrained with sucrose to come of their own accord to the experimental situation, no differences were found in the consequences of CI and S- training, perhaps because A added little to the excitatory value of the context (already very high) in which B occurred. In the new experiments, with harnessed subjects brought involuntarily into the training situation, negative results again were obtained. The possibility is considered that inhibitory conditioning in honeybees is independent of the excitatory value of the context.
在三项针对束缚状态下蜜蜂伸吻条件反射的实验中，对条件性抑制或CI训练（A+/AB-）与S-训练（A+/B-）进行了比较。目的是检验在脊椎动物文献中广受认可的雷斯克拉-瓦格纳假设，即非强化刺激会根据其呈现情境的兴奋值比例获得抑制特性。在之前对自由飞行的蜜蜂进行的实验中，这些蜜蜂预先用蔗糖训练，会自行来到实验情境，结果发现CI训练和S-训练的结果没有差异，这可能是因为A对B出现的情境（已经非常高）的兴奋值增加不多。在新的实验中，将束缚状态的实验对象非自愿地带入训练情境，再次得到了阴性结果。研究考虑了蜜蜂中的抑制性条件反射与情境兴奋值无关的可能性。
