单选题1 Erik Erikson believed that personality development is a series of turning points, which he described in terms of the tension between desirable qualities and dangers. He emphasized that only when the positive qualities outweigh the dangers does healthy psychosocial development take place. 2 An important turning point occurs around age six. A child entering school is at a point in development when behavior is dominated by intellectual curiosity and performance. He or she now learns to win recognition by producing things. The child develops a sense of industry. The danger at this stage is that the child may experience feelings of inadequacy or inferiority. If the child is encouraged to make and do things, allowed to finish tasks, and praised for trying, a sense of industry is the result. On the other hand, if the child's efforts are unsuccessful, or if they are criticized or treated as bothersome, a sense of inferiority is the result. For these reasons, Erikson called the period from age six to eleven Industry vs. Inferiority.
