Gustation: Taste Perception (Intro Psych Tutorial #53)

www.psychexamreview.com
In this video I explain the process of transduction for taste and how gustatory cells detect tastant molecules in food. I discuss structures of the tongue, including papillae, taste buds, and gustatory cells and consider evolutionary explanations for changes in the number of taste buds over time. I also mention the phenomenon of supertasters, who are more sensitive to taste and can detect compounds that non-supertasters cannot. Finally I consider how the experience of taste arises from the stimulation of 5 main types of gustatory cells, as well as the stimulation of other receptors, other senses, and even beliefs and expectations.
