It is interesting the definition that perception is composed of three components, a perceiving person, an object of perception, and an inferred interpretation. The definition is organized and clear. Additionally, I am interested in the fact I cannot see the pictures as both heads and vase at the same time when I see the two-headed vase illusion picture.
I want to know two things about perception. First, I would like to know the reason with the object of a brain science why I cannot throw away the interpretation which I had once. For example, when I saw the Language or designs at first time I could not notice the word “FIST”. However once I interpreted the word “FIST”, I could no longer miss the word. I want to know the mechanism why the above perception happens. Second, I want to find the way how to overcome some of the nature of perception. For instance, the nature of selective may narrow my vision. I want to collect a wide variety of information.
It was difficult to understand all main ideas of Fisher by myself. For example I misunderstood the meaning of the element of expectation. Fortunately due to the group discussion with my section mates I could comprehend the meaning that expectation changes the reality. It is good example introduced in the NP lecture that a doctor makes a wrong diagnosis on some patient's illness when he or she checks one hundred's X-rays of healty people because of expectation that there must be at least patients who have an illiness.
