Sensation And Perception

This chapter, by far, confused me the most. It messed up all my thoughts on perception and how our brains work with our senses. I learned that we only analyze three sets of different colors, red-green, yellow-blue, and black-white. In the retina and the thalamus, some neurons are turned "on" by red but turned "off" by green. I never knew that there was so many parts to the ear either. I mean, I know about the eardrum and the canal, but there is so much more. I also didn't know that there was actual bone in the ear. There are three varieties of ESP: telepathy, clairvoyance, precognition. All of these interests me because it is a claim to extra senses. Precognition I think is just a guess, if even that. You can get lucky on predicting some things. Like the Packer-Viking today, I could say that the Packers are going to win and I would have a 50 percent chance of being right. So, it is really just a guess. the other two may be plausible. Sometimes I have had a bad feeling about something and later learn a family member died, which would kind of be like clairvoyance. I don't know much about telepathy. I have never experience it before.
