One problem with much personality research is that it examines and rates whatever traits the researchers are interested in at the time: conscientiousness, emotional stability and so on. But when we 【C1】______someone in real life, we don"t consider an array of personality measures; instead, we focus on a few【C2】______ traits that sum up the【C3】______of the person. One is particularly anxious, another is【C4】______ reliable, yet another is a "live wire". While we might hesitate to characterize individuals along every personality dimension, we can accurately identify them【C5】______ their key characteristics. In research at Stanford University, Daryl Ben and Andrea Allen tested this idea by first asking college students【C6】______they were consistently or only occasionally friendly and then 【C7】______their parents and friends how friendly the students were. Ben and Allen observed how the students acted under two specific conditions:【C8】______they spoke in small groups and how quickly they 【C9】______a conversation with strangers. The researchers found that students who considered themselves consistently friendly were indeed more likely to be【C10】______ in both circumstances than were those who【C11】______ themselves only intermittently friendly. 【C12】______that, the friendliness ratings by parents and peers of the students who were consistently friendly were very similar【C13】______the students" self-ratings and【C14】______accurately how they would act in two conditions. It seems that we can【C15】______ourselves accurately and that others can rate us very well on traits【C16】______serve as our trademarks. To predict how someone will behave in a given situation, we must【C17】______ the requirements of the situation with the trademark characteristics of the person【C18】______. People who are strongly of one type or【C19】______should react predictably in a given situation,【C20】______the behavior of other, more diffuse personalities is harder to anticipate. 【C9】
