对看到食物时的唾液反应进行了研究，以确定其作为食欲定量和客观衡量指标的价值。在接触熟悉的食物之前和期间，使用一种简单的技术（用牙科棉卷）测量唾液分泌量。当受试者看到或想到美味的食物时，唾液分泌量经常增加。唾液分泌量随着人为控制的饥饿程度和食物可口性的变化而有显著且有意义的差异，并且与受试者的饥饿程度评分（r = 0.75）以及食物刺激的吸引力评分（r = 0.46）相关，这表明该测量指标从多个标准来看都能反映食欲。当受试者不期望吃到食物时，对食物刺激的唾液反应会减弱。由于这种方法利用的是一种无意识的反应，在食物调节的研究中，它应该被证明是对其他饥饿指标的一种有用补充。
&NA; Salivary response to the sight of food was studied to determine its value as a quantitative and objective measure of appetite. Salivation was measured by a simple technique using cotton dental rolls, before and during exposure to familiar foods. Increases in salivation occurred regularly when subjects looked at or thought of palatable food. The amount of salivation varied significantly and meaningfully with manipulated deprivation and palatability, and was correlated with subjects' ratings of hunger (r = 0.75) and appeal of the food stimuli (r = 0.46), indicating that the measure reflects appetite by several criteria. Salivary responses to food stimuli were found to be attenuated when subjects did not expect to eat the food. This method, because it employs an involuntary response, should prove a useful addition to other indices of hunger in studies of food regulation.
