根据心理学的观点，人的需要可分为外在性需要和内在性需要，外在性需要所瞄

According to psychological point of view, human needs can be divided into external needs and internal needs. The targets or stimulants targeted and pointed by the external needs are controlled by the external environment and cannot be controlled by the parties themselves. The need to satisfy and motivate the motivation comes from the work and learning itself. Therefore, the theory of the relationship between internal motivation and external motivation in psychology can be divided into four cases: when external motivation is strong and internal motivation is weak; when external motivation is weak and internal motivation is strong; both external and internal motivation are weak When; both external and internal incentives are strong. Only when both external and internal incentives are strong, work or study becomes fascinating and has very attractive incentives.

According to the psychological point of view, human needs can be divided into external needs and intrinsic needs, external needs and point to the target or inducing agent is the person itself can not control and the external environment, the satisfaction and motivation of intrinsic needs from the work and learning itself. Therefore, the theory of the intrinsic motivation of psychology and the theory of external motivation relationship can be divided into four kinds of situations: when the external motivation is strong and the inner incentive is weak, the external incentive is weak and the inner incentive is strong, the external incentive and the inner incentive are weak, and the external motivation and the inner incentive are strong. Work or study becomes fascinating and rewards with a lot of incentives when both external and intrinsic motivations are strong.

According to the psychological point of view, human needs can be divided into external needs and internal needs. The goals or inducements that external needs aim at and point to are controlled by the external environment and cannot be controlled by the parties themselves. The satisfaction and motivation of internal needs come from the work and learning of the parties themselves. Therefore, we can divide the theory of inner motivation and outer motivation into four situations: when the outer motivation is strong but the inner motivation is weak; when the outer motivation is weak but the inner motivation is strong; when the outer motivation and the inner motivation are both weak; when the outer motivation and the inner motivation are both strong. Only when both external and internal incentives are strong, can work or study become fascinating and have a rather stimulating reward.
