Odour aversion learning is often potentiated in the presence of flavour stimuli. Establishment of an aversion to an odour is greater when an odour + flavour compound is paired with illness than when the odour alone is paired with illness. Holland (1983) showed that under some circumstances auditory or olfactory stimuli previously paired with flavours may also potentiate odour aversion learning. The present experiments examined limitations on this representation-mediated potentiation of aversion learning. The results indicated that conditioned stimuli (CSs) that activate representations of potentiating cues are themselves immune to potentiation by other CS-activated representations, but remain susceptible to potentiation by their real stimulus associates.
气味厌恶学习在存在味道刺激的情况下通常会增强。当一种气味 + 味道化合物与疾病配对时，对气味厌恶的形成比单独将气味与疾病配对时更大。霍兰德（1983年）表明，在某些情况下，先前与味道配对的听觉或嗅觉刺激也可能增强气味厌恶学习。本实验研究了这种表征介导的厌恶学习增强的局限性。结果表明，激活增强线索表征的条件刺激本身不受其他条件刺激激活表征的增强作用影响，但仍易受其实际刺激关联物的增强作用影响。
