It has been suggested that humans can perceive only four tastes, salty, sweet, sour, bitter, but can recognize thousands of smells which suggest that smell and taste are related. Smell is capable of a much wider variance because it detects actual chemical molecules released into the air, and further refines them by their intensity.
The ability to distinguish various foods relies predominantly on the sense of smell. This explains why foods seem to have little taste for a person who is suffering from a head cold. The taste and smell of appetizing foods prepare the digestive tract for digestion by stimulating the flow of saliva in the mouth and gastric juice in the stomach.
Our chemoreceptor’s used for both taste and smell adapt quickly to any stimulus. The nasal cavity and oral cavity are closely connected, separated only by the palate. So it makes sense that the two senses go hand in hand.
A hypothesis is a proposed explanation for a phenomenon. For a hypothesis to be put forward as a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories.
If you believe that smell and taste are related then a possible hypothesis could be, ‘I believe that smell affects the way people perceive taste.’ To successfully test your hypothesis you should carry out some kind of scientific test. A suggested test to establish whether taste and smell are related would be to blocking each sense independently and then test and identify foods. Your results should determine which of the two senses send the clearer message to the brain on what you are eating. After your hypothesis you should include the Measured Variables, Experimental Groups, Materials, Procedures, Results, which should include a table and your Conclusion.
