When several different people look at the same person, it is not unusual for each of them to see different things; when you alone observe one behavior or one person at two different times, you may see different things. The following are but some of the factors that lead to these varying perceptions: Each person’s perceptions of others are formed by his or her own cultural conditioning, education, and personal experience. Sometimes perceptions differ because of what we choose to observe and how we deal with what we’ve observed. It is not necessarily true that person’s perception is based on observations of a particular person. Your observations may be totally controlled by some. Your observations may be totally controlled by what others have told you about this person; or you may focus primarily on the situation or role relationship. Most people do not use the same yardstick to measure their parents, their friends, and strangers. Sometimes we see only what we want to see what may be obverse to others because of our own needs, desires, or temporary emotional states. This is a process known as selective perception. Selective perception is obviously more difficult when contradictory information is particularly obvious, but it can be done. We can ignore the stimulus—“He’s basically a good boy, so what I saw was not shoplifting.”  We can reduce the importance of the contradictory information—“All kids get into mischief(顽皮). Taking a book from the bookstore isn’t such a big deal.” We call change the meaning of the contradictory information—“It wasn’t shoplifting because he was going to pay for it later.”.. 1.While observing a particular person,        .
