动机的概念

Motivation is a word used to refer to the reason or reasons for engaging in a particular behavior, especially human behavior as studied in psychology and neuropsychology. These reasons may include basic needs such as food or a desired object, goal, state of being, or ideal. The motivation for a behavior may also be attributed to less-apparent reasons such as altruism or morality. Motivation refers to the initiation, direction, intensity and persistence of human behavior.

In knowledge-sharing communities and organizations, people often cite altruistic reasons for their participation, including contributing to a common good, a moral obligation to the group, mentorship or “giving back”. In work environments, money may provide a more powerful extrinsic factor than the intrinsic motivation provided by an enjoyable workplace.

The most obvious form of motivation is coercion, where the avoidance of pain or other negative consequences has an immediate effect. Extreme use of coercion is considered slavery. While coercion is considered morally reprehensible in many philosophies, it is widely practiced on prisoners, students in mandatory schooling, within the nuclear family unit (on children), and in the form of conscription. Critics of modern capitalism charge that without social safety networks, wage slavery is inevitable. However, many capitalists such as Ayn Rand have been very vocal against coercion. Successful coercion sometimes can take priority over other types of motivation. Self-coercion is rarely substantially negative (typically only negative in the sense that it avoids a positive, such as forgoing an expensive dinner or a period of relaxation), however, it is interesting in that it illustrates how lower levels of motivation may be sometimes tweaked to satisfy higher ones.

动力的减弱

There are a number of drive theories. The Drive Reduction Theory grows out of the concept that we have certain biological needs, such as hunger. As time passes, the strength of the drive increases as it is not satisfied. Then as we satisfy that drive by fulfilling its desire, such as eating, the drive‟s strength is reduced. It is based on the theories of Freud and the idea of feedback control systems, such as a thermostat.

There are several problems, however, that leave the validity of the Drive Reduction Theory open

for debate. The first problem is that it does not explain how Secondary Reinforcers reduce drive. For example, money does not satisfy any biological or psychological need but reduces drive on a regular basis through a pay check second-order conditioning. Secondly, if the drive reduction theory held true we would not be able to explain how a hungry human being can prepare a meal without eating the food before they finished cooking it.

内在驱动和外在刺激

Drives and desires can be described as a deficiency or need that activates behavior that is aimed at a goal or an incentive. These are thought to originate within the individual and may not require external stimuli to encourage the behavior. Basic drives could be sparked by deficiencies such as hunger, which motivates a person to seek food; whereas more subtle drives might be the desire for praise and approval, which motivates a person to behave in a manner pleasing to others.

By contrast, the role of extrinsic rewards and stimuli can be seen in the example of training animals by giving them treats when they perform a trick correctly. The treat motivates the animals to perform the trick consistently, even later when the treat is removed from the process.
