Today I also talk about the?crash course psychology class
In this class main talk about the perception and feeling.
For example the Oliver sacks the famous physician and professor.
He has a form of prosopagnosia which also known as face blindness
This example proved that sensation is the bottom-up process by which of our sense.
Perception, on the other hand is the top-down way our brains organize and interpret.
These makes me feel the ingenuity of our brain. Which is a very magical and fun.
And the Weber's Law: Perceived difference and stimulus brightness are logarithmic, not linear
In fact, I don't fully understand the meaning, ?however, I know that some times I can heard some slight voice ,but some time can’t. it has the reason.
The other magical part of our brain is the Parallel processing: the ability to process and analyze individual information.it Handle multiple things at the same time.
