Effects of deprivation on salivary flow in the apparent absence of food stimuli.
Salivation performance in the absence of food-related stimuli was measured with an absorbent technique in 19 subject under no (0-1 h) and moderate (4-6 h) levels of food deprivation. Overall, salivation was reliably (p less than 0.05) greater the higher the hours of deprivation. Results also revealed a reliable positive correlation between hours of deprivation and subjective ratings of hunger. For subjects whose hunger ratings coincided with hours of deprivation, analysis of the salivation data yielded highly reliable (p less than 0.01) differences due to deprivation/hunger. For subjects who reported the same level of hunger at different hours of deprivation, there were no reliable differences in salivation due to deprivation.
