TIME-INTENSITY STUDY OF PROLONGED SWEET STIMULI

Prolonged intensity and hedonic (like/dislike) temporal responses and any associated adaptive behavior toward various sweet solutions (sucrose in water) were investigated with specific focus on factors that influenced the transition from "like" to "dislike." Subjects evaluated the samples using computerized time-intensity (T-I) methods to produce sweetness intensity-time and like/dislike-time response curves. The higher concentration solutions resulted in adaptive behavior. Also, like-to-dislike transition times correlated with sucrose concentration, as did other defined parameters which characterized aspects of the responses, several of which displayed significant cross correlations.
