Experiment 4 With this experiment we will fill three bowls with different temperature in each bowl. The bowl on the left there will be hot water. The one on the right is cold water, and then the middle has warm water. Now taking your hand and submerge them in the appropriate bowls and what is it you feel? Here the experience that was recorded was the water on the left hand stayed the same but the reaction on the right hand was that the water seemed to feel like it was getting cooler. See when I had done this experiment I had reverse the process by accident and I could not keep my right hand in the water for that first three minute that the experiment had asked for. The water was only
108 degree but felt very hot like stepping into a hot shower and the water stings your skin. What ten minutes and did experiment the right way and noticed the water seems to get colder. So with the experiment perspectives the reaction to the sensory was the same just in reverse. That is way the water was to be cold on the right side. These receptors are located in the epidermis (layers of skin cells, the outermost of which are dead) and the dermis (the Layer of skin below the epidermis) Nerves connect back from these layers of skin to the brain, carrying the impulses there. Where they are turn into sensations. (Intro to phycology) pg. 60 The Teromrecetors are sensory unique to the experiment along with Proprioception and anterolateral system which carries information about pain and pressure. (Intro to psyco) pg.63
The skin has a variety of separated receptors. These are nerve endings that are sensitive to outside stimuli such as heat, pressure, vibration, tickling, disruption and itching (Benson,1982).
So the two sensors that were used in this experiment are: Thermo receptors – sensory receptors in the body that respond to change in temperature. Nocie receptors – which respond to damage to the body usually in the form of pain.
With this experiment you want to get two glasses of water. After getting the water take about a table spoon of sugar and mix it in one of the glasses. After the sugar dissolves taking a large sip of water holding it in your mouth till you don’t sense the sweetness in your mouth. Well the experiment took about 15to 25 sec for it not to be as sweet as the first taste in the mouth. Now, spit out the sweet water and take a sip of tap water. Here was the experience on the tongue taste bud felt like they stood up and were waiting for some other sense. It was a surprise to my thoughts and to the tongue. The thought was as the feeling of the tongue taste buds felt like they were literally standing awaiting the next taste. The part of the brain that is being used at this process is called the limbic system. This is emotion and memories are processed. Taste travels from the mouth to the brainstem via three different cranial nerves-the facial nerve, the glossopharyngeal nerve and the vagus nerve. From nuclei in the brainstem, information about taste travels to the thalamus and then to the cortex,
Factors affecting taste are; visual, shape, texture and temperature to mention a few. (Intro to phycology.) pg.59,60 Here are using the Chemoreceptor this is where smell and taste located in the nose and mouth. Although tastes of food signals weather the foods are safe and nutritious
(sweet foods are usually safe and bitter foods are often not), adults in modern society generally eat for pleasure. (Intro to phycology)pg. 60 Sensory cortex – an area of the brain that receives input directly from parts of the thalamus and also receives input either from the primary cortex or form other secondary areas.

My “sandpaper” for this experiment was a nail filer.
