The Influence of Perceived Spiciness on Actual Taste Experience: An Experimental Study

This study investigates the influence of information on the perception of spiciness. We conducted an experiment with 10 subjects, each of whom was given food with a spiciness level ranging from 1 to 10. The subjects were informed about the spiciness level of the food, but the information given was randomly varied to be higher or lower than the actual spiciness level. The subjects' perceived spiciness level was then measured. Our results show a significant influence of information on the perception of spiciness. On average, the perceived spiciness level was found to be about 22\% different from the actual spiciness level, with a range from 12\% to 40\%. This effect was observed for all subjects and across all spiciness levels. These findings have implications for understanding the psychological factors that influence the perception of sensory experiences.
