Study Summary

Increasing exposure to a single orosensory cue without ingestion of additional energy may promote an increased rate of habituation, more rapid satiation, and reduced intake. This exposure can occur via smell (olfactory) and taste (gustatory) systems.It is not clear if repeated exposure via the combined olfactory and gustatory systems increases the rate of habituation more so than repeated exposure through one of these systems. Thus, the purpose of this investigation is to examine the amount of salivation occurring in 12 trials of exposure to a food via the olfactory, gustatory, and combined olfactory and gustatory systems. The primary dependent variable will be the amount of salivation in the 12 trials. It is hypothesized that a more rapid decrease in salivation will occur across trials in the combined olfactory and gustatory exposure as compared to the other two conditions, indicating a more rapid rate of habituation.
