Have you ever bought something just because the salesman talked you into it?  Many people are afraid to support themselves. Dr. Robert Albert， author of Stand Up， Speak Out， and Talk Back，thinks it’s because their self-respect is low. “There s always a ‘superior’ (长辈) around ˉa parent， a teacher， a boss—— who knows better.” But Albert and other scientists are doing something to help people help themselves. They offer “assertiveness(维护) training” courses——A.T. for short. In the A. T. Course people learn that they have a right to be themselves. They learn to speak out and feel good about doing so. They learn to be aggressive (进攻的) without hurting other people. In one way， learning to speak out is to get rid of fear. A group taking an A. T. Course will help the timid (懦弱的) person to lose his fear. But A. T. uses an even stronger motive (动机)——the need to share. The timid person speaks out in the group because he wants to tell how he feels. Whether or not you speak up for yourself depends on your self-respect. If someone you face is more “important” than you， you may feel less of a person. You start to doubt your answers to problems. You can get to feel good about yourself. And once you do you can learn to speak out. 1.
