a sense of restriction on the employee and these constraints are viewed as “annoying and seemingly functioned only as subordinating or differentiating mechanisms." Accordingly, the natural management system assumes that employees prefer autonomy and responsibility on the job and dislike arbitrary rules and overwhelming supervision. An individual's motivation to complete a task is increased when the task is autonomous. When the motivation to complete a task comes from an "external pressure" that pressure then "undermines" the person's motivation, and as a result decreases the person's desire to complete the task. Rational motivations The idea that human beings are rational and that the human behavior is guided by reason is an old one. However, recent research (on satisfying for example) has significantly undermined the idea of homo economicus or of perfect rationality in favor of a more bounded rationality. The field of behavioral economics is particularly concerned with the limits of rationality in economic agents. Incentive theories: intrinsic and extrinsic motivation Motivation can be divided into two different theories known as intrinsic (internal or inherent in the activity itself) motivation and extrinsic (contingent on external rewards or punishment) motivation. Intrinsic motivation Intrinsic motivation has been studied since the early 1970s. Intrinsic motivation is a behavior that is driven by satisfying internal rewards. For example, an athlete may enjoy playing football for the experience, rather than for an award. It is an interest or enjoyment in the task itself, and exists within the individual rather than relying on external pressures or a desire for consideration. Deci (1971) explained that some activities provide their own inherent reward, meaning certain activities are not dependent on external rewards. The phenomenon of intrinsic motivation was first acknowledged within experimental studies of animal behavior. In these studies, it was evident that the organisms would engage in playful and curiosity-driven behaviors in the absence of reward. Intrinsic motivation is a natural motivational tendency and is a critical element in cognitive, social, and physical development. The two necessary elements for intrinsic motivation are self-determination and an increase in perceived competence. In short, the cause of the behavior must be internal, known as internal locus of causality, and the individual who engages in the behavior must perceive that the task increases their competence. According to various research reported by Deci's published findings in 1971, and 1972, tangible rewards could actually undermine the intrinsic motivation of college students. However, these studies
