You may have learned that man has five senses that are related to the five sensory organs: Vision (eye), Hearing (ears), Tasting (tongue), Tasting (skin), and scavenging (nose). In fact, there are more than five senses, though scientists do not agree on exact numbers. The skin, which is a touch or pressure organ, can also feel the heat, cold, pain, tingling and itching. The ear which is the organ of hearing also has a receptor that forms the sense of balance. The muscles of the body also have receptors that are responsible for the sensation of body movement.
All our senses thrive to help us survive. Even the pain that causes a lot of human suffering, is an inseparable part of our evolutionary heritage, because pain can warn us of illness and injury. People born with a sensory condition that makes them unable to feel pain and injury will be especially vulnerable to burns, bruises, and fractures, and often they die young because they can not take advantage of pain alert signals.
Experience sensory contribute countless on the quality of our lives, even when the experience not directly help us to stay alive. the experience entertaining, stunning, soothing, and give us inspiration.
Feel the sensation without make perception
If too little stimulation can be bad for us, so too much stimulation, because it can lead to fatigue and confusion. When we feel very tired, anxious, and headaches after a day of activity, we already understand the effects of sensory overload. When a person finds himself mentally overloaded, they often overcome it by removing unnecessary sightings or useless sounds and focusing only on things that are considered interesting and useful. Psychologists call this the "cocktail party phenomenon" because at a very crowded cocktail party it's usually someone just focusing on one conversation, and ignoring the other. It was like a clatter of laughter that filled the entire room.
Even when mental overload does not matter, our ability to take selective attention protects us from the bustling of countless sensory signals, which constantly meet our sensory receptors. Nevertheless, competing sensory messages all remain in the nervous system and remain in process, allowing us to choose what is more important.
