Abstract:
While the senses of taste, smell, and vision are distinct, visual stimuli have been shown to alter the perception of taste, smell, and flavor. Color may be the most obvious visual cue, but expectations through learned associations are set by other visual cues as well, including gloss, evenness, and shape. These expectations exert cognitive top-down influences that can and sometimes do alter assessments of taste and flavor.
