Even though the senses of taste, smell, and sight are distinct, there is a significant overlap among them in our perceptions of objects that helps us understand and differentiate the world. Everyone has experienced, when his or her nose gets congested, that his or her sense of taste changes as well. Many individuals do not equally understand the top-down processing with taste when someone sees objects they are about to eat. In the replicated study by our principle investigator, a random convenience sample of young adults (n=162) were recruited and tested to determine if they could taste four Jelly Belly flavors with one of the three different conditions: taste alone, taste with smell, or taste with smell and sight. The study revealed significant differences between the number of sensory systems used and the accuracy of flavor detection. However, no significant differences in results were observed between genders and/or for smokers versus non-smokers.
