研究人员对在蜂巢和打开的实验室窗台之间来回飞行的单个蜜蜂进行了厌恶条件反射研究，它们从目标中获取蔗糖溶液，目标的构造使得当喙与溶液接触时可以传递冲击。在喂食过程中，条件刺激——基质振动或气流——与短暂的震动相结合，可以通过中断喂食来避免。在实验 1 中，发现未强化的条件刺激预暴露会延迟习得（潜在抑制）。在旨在探究效果的刺激特异性的实验 2 中，发现差异调节会因未强化的预先暴露的正刺激而受到损害，而会因未强化的预先暴露的负刺激而受到损害。在实验 3 中，一项旨在测试该效应的各种替代解释的求和实验中，发现当两种刺激同时出现时，预先暴露的刺激会抑制对兴奋性条件刺激的反应。
Aversive conditioning was studied in individual honeybees flying back and forth between the hive and the sill of an open laboratory window, where they took sucrose solution from a target so constructed that shock could be delivered while the proboscis was in contact with the solution. During feeding, a conditioned stimulus-substrate vibration or airstream-was paired with brief shock avoidable by interruption of feeding. In Experiment 1, unreinforced preexposure of the conditioned stimulus was found to retard acquisition (latent inhibition). In Experiment 2, which was designed to inquire into the stimulus specificity of the effect, differential conditioning was found to be impaired by unreinforced preexposure of the positive stimulus and facilitated by unreinforced preexposure of the negative stimulus. In Experiment 3, a summation experiment designed to test various alternative explanations of the effect, a preexposed stimulus was found to suppress response to an excitatory conditioned sitmulus when the two stimuli were presented together.
