When we taste delicious food, are we experiencing a sensation or a perception? The terms "sensation" and "perception" are often used interchangeably in most of our language. However, from the psychology textbook, I found these two terms are very different. Sensation is determined as the passive process of gathering information from the outside world into the body and to the brain. Sensation is including what we see, what we hear, what we smell, what we taste, and what we feel about our bodies. Perception is determined as the active process of picking up the signals in our environment and interpreting the information brought to our brain into something meaningful. Our senses allow us to experience the world we live in, and sensation is related to our five senses. If our world is without our senses, the world we live in would be very different and we cannot experience the variety of things in the world. The learning would become impossible if we cannot experience the whole world. We must first experience variety of things and then learn something. So that is why I believe the term "sensation" is important. h_large_trIr_2ace00007c8d2f74.jpg
When I was in elementary school, one of my classmates was a deaf-mute person. Even she had hearing aid at that time, she had great difficulties in listening what instructors said and talking with instructors and us. She could not hear us clearly. She usually used sign language to communicate with instructors and us. Sometimes we could understand her, but sometimes not. As a deaf-mute person, she could not learn knowledge in class very well. Deafness and muteness not only influence her life in learning in school, but also influence her life in other aspects. I found this video about how deafness and muteness influence people's lives. I am still wondering about can certain blind people still feel their surroundings using other four senses.
