Sensation is what we sense in our environment. We use all of our senses (hear, feel, touch, smell, see) in this process. Our nervous system plays a big part in sensation, having our sensory receptors telling us to respond to whatever we sense. Perception is taking what we sense in our environment, and breaking it down into what it really means. For example, we could sense that something is brushing up against our body, but it would take perception to figure out just what the thing is.
Even though I've learned about this in previous science classes, I think it's always intriguing to learn more about color vision. The example given in the book shows us how a tomato really is everything but red, because it rejects the long wavelengths of the color red. The book also mentions that we can discrimante about 7 million different colors variations-that is absolutely crazy. But about everyone 1 in 50 people is color blind. It's usually a male that is affected, because this defect is sex linked. I also learned that according to the Young-Helmholtz trichromatic theory, our the retinas in our eyes contain three different color receptors, and when they are stimulated in any combination, we can percieve pretty much any color. Learning about this helps me to realize why we visually see things the way we do.
I typed in "sensation" and read the article "Seven Ways Music Influences Mood." Having a strong sensation is one of the top reasons. It says that music can provide deep, thrilling, emotional experiences, especially if you are performing. Also on the list was entertainment, revival, diversion, discharge, mental work, and solace. Altogether these seven objectives have a main goal-to control and improve a mood. I can totally relate to this article. I have a very big passion for music and I resort to it in pretty much any situation. Music is a way for me to relax and just think about something else for the time being.

Yea I can't believe how much is apart of our eyes and how we see. There are so many things going on behind the secnes that I had no idea were going on. Especially with all the cooperative work that goes on between certain parts of the eye. I also agree with the aritlce that you read. Music can totally affect my mood. Or sometimes my mood can affect the type of music I want to listen to. It's very intersting.
ReplyDeleteRian! You're right-color vision is very fascinating! It's amazing that the human eye can detect so many different colors as well! (should we try naming them? haha) Also, I agree with the correlation between music and sensation. I really think simply hearing different types of music can affect ones mood, even if they aren't truly "listening."
ReplyDeleteI read that article about music affecting our moods also. I love music and I listen to it whenever I can. Music will usually take my mind off a problem at hand and put me in a great mood after a horrible day. Usually when I'm listening to music in a quiet place, like my room, I daydream a lot and my mind wanders off of whatever I am doing. Music is just peaceful to me and takes me to a different time and place.
ReplyDeleteI find color vision really interesting. It's so weird knowing that wavelengths and the light around objects create color that we see. It's also weird thikning that not everyone sees the same colors because of color blindness. I can really relate to the music that you talked about. Music is a way for me to escape for a while. I love to perform in choirs and such, which usually puts me in a good mood.
