Document Summary
Most of what we talk about today is not in textbook. There are a series of info processing that cognition involves: stimulus energy -> sensory system -> transduction -> iconic/echoic storage -> longer term memory (different wavelengths of lights stimulate. Photo receptors in eye balls then a signal is sent to brain. Then transduction is when the light energy is converted into a neural code that the brain understands, then the storage is our short term memory and then some goes to our long term memory) Contralatery (things re processed on other side of brain, as information received from the right eye is processed in the left hemisphere of the brain) Ciliary muscles pull on the eye lens if a person is looking at something far away. When looking at things that are closer then the muscles relax and the lens becomes more round) Rods: photoreceptors we have the most of, they are active in dark conditions.
