Two experiments were done to study inhibition of cue-dependent salivation and craving responses. Experiment 1 suggests that total prevention of tasting during cue exposure inhibits salivation responses to chocolate cues. On the other hand, salivation was triggered by chocolate cues after tasting a very small amount of chocolate, indicating a very robust and rapid learning of conditioned salivation responses. However, prevention of tasting during cue exposure did not affect craving, suggesting that this method cannot decrease craving or that craving is affected at different rate than salivation. Experiment 2 tested the hypothesis that tasting irrelevant food during repeated exposure to chocolate cues would inhibit anticipatory salivation and craving responses to these cues. No support for this hypothesis was observed.
进行了两项实验来研究线索依赖性唾液分泌和渴望反应的抑制作用。实验1表明，在线索暴露期间完全阻止品尝会抑制对巧克力线索的唾液分泌反应。另一方面，在品尝极少量巧克力后，巧克力线索会引发唾液分泌，这表明条件性唾液分泌反应的学习非常迅速且强烈。然而，在线索暴露期间阻止品尝并不影响渴望，这表明这种方法无法减少渴望，或者渴望受到的影响与唾液分泌的速度不同。实验2检验了这样一个假设，即在反复暴露于巧克力线索期间品尝无关食物会抑制对这些线索的预期唾液分泌和渴望反应。但该假设未得到支持。
