Gustation and Olfaction
Gustation and olfaction, better known as taste and smell, are chemical senses. Their receptors are sensitive to chemical molecules, which differ from the other senses that detect forms of energy. Gustation and olfaction are intertwined. Referred to as a ‘common chemical sense,’ both must simultaneously activate in order for stimuli to be fully tasted and assessed. The little knobs along the tongue’s surface are papillae, divided into fungiform and filiform types on the front half, and foliate and vallate types on the back half. The human tongue has around 9000 taste buds, clustered within the papillae, which act as receptors for taste. The taste buds are concentrated along the edges and back surface of the tongue, in the roof and back of the mouth. They are sensitive to the qualities of sweet, sour, salty and bitter, and are arranged in different areas according to which taste sensation they are most sensitive towards. When something enters the mouth, its chemicals are dissolved by the saliva, and the free-floating molecules enter the taste bud through a pore in its centre. If the molecule binds to the tip of a receptor cell, it will excite that cell into issuing a series of chemical and electrical signals. Across the cel
In the four situations investigated, participants will have: The participants used in this experiment were students enrolled in the Psychology 1000 tutorials. They were male and female, approximately between the ages of 18-25. None of the participants reported having any known food allergies. Another factor that may have influenced the results was the actual flavors of the candies. Strawberry and Banana flavored candies were more easily identified then Peach and Pineapple. This may be because Strawberry and Banana are more distinct and distinguishable flavors then the other two. 6. The new participant (b) ate one jelly belly for Condition A3: Eyes closed, nose closed. Participant (a) would record the colour of the jelly belly on the data sheet.
