Abraham Maslow's hierarchy of needs and the ERG theory, for example, posit that humans have certain needs, which are responsible for motivation. They are known as content theories and aim to describe what goals usually or always motivate people. Various competing theories have been proposed concerning the content of motivational states. The psychological elements fueling people's behavior in the context of job goals might include a desire for money. It is the process of motivating individuals to take action in order to achieve a goal. Motivation is derived from the word 'motive,' which denotes a person's needs, desires, wants, or urges. But various other states, such as beliefs about what one ought to do or intentions, may also provide motivation. The paradigmatic mental state providing motivation is desire. This means that we can be motivated to do something without actually doing it. It is often held that different mental states compete with each other and that only the strongest state determines behavior. Motivational states are commonly understood as forces acting within the agent that create a disposition to engage in goal-directed behavior. Motivation is the reason for which humans and other animals initiate, continue, or terminate a behavior at a given time.
