Adolescence is a period of rapid physical and mental change. Physical growth is rapid, cognitive development advances from the stage of concrete imagery to abstract logic, and striving for independence increases. Because cognitive development lags behind this growth in independence, juveniles often hold anarchistic and erroneous attitudes, values, and morals that make them easy prey for criminal activity. Young people also have lively emotions. They often are impulsive, emotionally unstable, and unable to control themselves. In delinquents, these characteristics may express themselves through self-will, arrogance, lack of sympathy for others, and reliance on the influence of delinquent peers. Finally, adolescents have strong desires and motivations. When these are rooted in the collective welfare of China's socialist society, these motivations are good, when they are rooted in individual interest, they are not. Common motives for juvenile crime are usually based on individual interests and may include self-gratification, revenge and jealousy, or curiosity. By giving adolescents love, a good environment, and correct guidance, delinquency can be prevented.
