Clark Hull's drive-reduction theory, introduced in the 1940s and 1950s and often termed the "push theory" of motivation, provides a framework for understanding how biological and learned drives influence behavior. Hull suggested that motivation originates from the need to alleviate physiological tension caused by unmet biological necessities. The theory proposes that when a basic need, such as hunger or sleep, goes unfulfilled, it creates an internal imbalance. This imbalance, or...

The most basic experimental design involves two groups: the experimental group and the control group. The two groups are designed to be the same except for one difference— experimental manipulation. The experimental group gets the experimental manipulation—that is, the treatment or variable being tested—and the control group does not. Since experimental manipulation is the only difference between the experimental and control groups, we can be sure that any differences between...

Incentive theory, or the "pull theory" of motivation, suggests that external rewards primarily drive behavior. Individuals are motivated to engage in activities when they anticipate a desirable outcome. This is why people often work hard for promotions or study intensively to achieve high grades. These incentives can be tangible, physical rewards such as money or promotions, or intangible, non-physical rewards like praise and social recognition.
The theory differentiates between...

Self-Determination Theory (SDT), formulated by Richard Ryan and Edward Deci, explains that human motivation is driven by three fundamental psychological needs: autonomy, competence, and relatedness. When these needs are met, individuals experience personal growth, intrinsic motivation, and overall well-being.
Autonomy is the need to feel in control of one's actions and decisions. For example, a student who chooses their research topic is likely to be more engaged and motivated than one who...

Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Power motivation and achievement motivation are two essential social motives identified by psychologist David McClelland. These motives influence behavior in various personal and professional contexts, shaping how individuals interact with others and pursue their goals.
Power motivation is characterized by the desire to influence, control, or have an impact on others. It is shaped by an individual's experiences, social environment, and cultural context. People with high power motivation are...
