Motivation is a theoretical construct, used to explain behavior. It is the scientific word used to represent the reasons for our actions, our desires, our needs, etc. Motives are hypothetical constructs, used to explain why people do what they do. A motive is what prompts a person to act in a certain way or at least develop an inclination for specific behavior. For example, when someone eats food to satisfy the need of hunger, or when a student does his/her work in school because they want a good grade. Both show a similar connection between what we do and why we do it. According to Maehr and Meyer, "Motivation is a word that is part of the popular culture as few other psychological concepts are".

In evolutionary psychology, the "ultimate", unconscious motivation may be a cold evolutionary calculation, the conscious motivation could be more benign or even positive emotions. For example, while it may be in the best interest of a male's genes to have multiple partners and thus break up with or divorce one before moving onto the next, the conscious rationalization could be, "I loved her at the time". 
Freud is associated with the idea that human beings have many unconscious motivations that cause them to make important decisions because of these unconscious forces, such as choosing a partner. According to Freud and his followers, majority of the how people in different situations/environments are the result of desires, impulses, and memories that have been imprinted into an individual unconscious state, however it would still influence their performances or actions.
Some psychologists believe that a significant portion of human behavior is energized and directed by unconscious motives. According to Maslow, "Psychoanalysis has often demonstrated that the relationship between a conscious desire and the ultimate unconscious aim that underlies it need not be at all direct."
