Research suggests that parents who reward self-control and independence tend to have children with high achievement motivation(动机). Such parents set high standards for their children but allow them to work at their own level and to make their own mistakes. By contrast, parents of low need achievers typically set impossibly high goals for their children and make extreme demands. In addition, parents of high need achievers encourage good performance but do not reproach their children when they fail. If a child comes home from school with four A’s and one B on a report card, the parents focus on the A’s; parents of a potentially low need achiever tend to ask, “why the B?” Parents of high need achievers respond to mediocre (普普通通的) grades with warmth and suggestions for reasonable goals and ways to reach them. Parents of low need achievers might say, “You’re dumb and lazy you’ll never amount to anything”, and punish the child. When a child is having trouble with a math problem, the parent of a potentially high need achiever will suggest the general measures and let the child work out the particular solution; a low need achiever’s parent will solve the problem and then hand the child the answer.That needs for affiliation (隶属关系) and achievement exist within all of us, to varying degrees, is undeniable (不可否认的). And although biological bases for at least the affiliation need have been proposed, a great deal more is known about the psychological bases of these needs and how they come about.Closely related to motivation are emotions, which can activate (刺激) and direct behavior in much the same way as physiological, social, and psychological motivations do.不要自动翻译！谢谢！
