perception test

my impressions of the lecture test were that how oblivious the human brain really is. it amazed me that the mind is an auto correcter and, if needed, appears to add and eliminate words when needed. also, it still amazes me that when the human brain focuses on one thing, it can block out all other images and sounds. i think that people should know how much our brains filter the world around us. people shoud understand exactly why we do not remember, hear, or see the majority of things that are going on around us.
