Document Summary

The entire constellation of factors, some inside the organism and some outside, that cause an individual to behave in a particular way at a particular time. Motivational state or drive - denote an internal condition that orients an individual toward a specific category of goals and that can change over time in a reversible way. Drive in psychology are generally thought of as hypothetical constructs. Drives and incentives complement each other in control of behaviour and influence. Incentives (reinforces, rewards, goals) each other"s strength, if one is weak the other has to be strong to motivate goal directed action. A strong drive can enhance the attractiveness (incentive value) of a particular object and vice versa. Physiological processes such as digestion and respiration must continually work toward achieving homeostasis. The constancy of internal conditions that the body must actively maintain. Cannon pointed out that maintaining homeostasis involves the organisms outward behaviour as well as its internal processes.
