The rapid release of saliva following cognitive or sensory stimulation is termed the cephalic phase salivary response. Optimal methods and conditions for measuring the cephalic phase salivary response have not been established. Consequently, determination of the extent to which the large inter and intra-individual variability reflect biological or procedural influences is not possible. The nutritional significance of the response may be great due to the multiple roles played by saliva in food selection and digestion. The cephalic phase salivary response has been proposed as an objective index of various individual states (e.g. hunger) and characteristics (e.g. dietary restraint, extroversion), but its value for such purposes requires further verification.
认知或感官刺激后唾液的快速分泌被称为头期唾液反应。目前尚未确定测量头期唾液反应的最佳方法和条件。因此，无法确定个体间和个体内的巨大变异性在多大程度上反映了生物学或操作上的影响。由于唾液在食物选择和消化中发挥多种作用，这种反应的营养意义可能很大。头期唾液反应已被提议作为各种个体状态（如饥饿）和特征（如饮食限制、外向性）的客观指标，但其在这些方面的价值仍需进一步验证。
