Self-Determination Theory (SDT) is a psychological framework that emphasizes the role of intrinsic motivation and the fulfillment of basic psychological needs—autonomy, competence, and relatedness—in fostering optimal human functioning and well-being. It posits that environments supporting these needs enhance motivation and personal growth, while those that thwart them can lead to diminished motivation and well-being.
The overjustification effect occurs when an external incentive like a reward decreases a person's intrinsic motivation to perform a task they already find enjoyable. This phenomenon suggests that while rewards can initially boost performance, they may ultimately undermine a person's internal desire to engage in the activity for its own sake.
Reinforcement Theory, rooted in behaviorism, posits that behavior is a function of its consequences, meaning positive reinforcement increases the likelihood of a behavior recurring, while negative reinforcement or punishment decreases it. This theory is widely applied in fields such as psychology and organizational behavior to shape and modify behavior through systematic reinforcement strategies.
Theory X and Theory Y are two contrasting management styles proposed by Douglas McGregor that depict two different views of workforce motivation and behavior. Theory X assumes that employees are inherently lazy and need constant supervision, while Theory Y believes that employees are self-motivated and thrive on responsibility if given the right conditions.
