当食物提取物与平衡囊的旋转产生的刺激配对时，发现由嘴唇的化学感觉刺激引起的Hermissenda crassicornis的咬击反应被修改。动物接受重复配对的提取物1的食物（条件刺激，CS）与旋转表现出抑制咬罢工的反应，该食物长达48小时训练后。这种抑制通常是特定于训练的食物，也是配对特异性的。还证明了条件反射。训练的动物是1个与旋转配对的CS和未配对的第二个CS（CS-），对第一个CS表现出抑制的咬击反应。结果表明，Hermissenda可以学会避免食物，可靠的信号一个令人厌恶的事件，并可能允许更高阶的条件反射现象的分析。
Bite–strike responses of Hermissenda crassicornis, elicited by chemosensory stimulation of the lips, were found to be modified when food extracts were paired with rotation-produced stimulatioin of the statocysts. Animals that received repeated pairings of an extract of 1 food (conditioned stimulus, CS) with rotation exhibited suppressed bite–strike responses to that food for up to 48 hr after training. This suppression was usually specific to the trained food and was pairing-specific as well. Discriminative conditioning was also demonstrated. Animals trained was 1 CS paired with rotation and a second CS that was unpaired (CS−) showed suppressed bite–strike responses to the first CS. The results demonstrate that Hermissenda can learn to avoid foods that reliably signal an aversive event and may allow an analysis of higher order conditioning phenomena.
