Document Summary

Biological factors in the regulation of hunger 3. Environmental factors in the regulation of hunger 5. Drive theories appear in a vast array of theories such as psychoanalytic and behaviourist formulations. A drive is an internal state of tension that motivates an organism to engage in activities that should reduce this tension: homeostasis: a state of physiological equilibrium or stability. When individuals experience a drive, they are motivated to seek actions that will bring about drive reduction. When in class for long periods of time, an individual can experience discomfort which then motivates him/her to obtain food, effectively reducing that physiological drive. Drive theories cannot explain all motivational aspects because of its consistent belief that one"s drive is triggered by physiological tension. This is not the case for every motivational decision. Incentive theories propose that external stimuli regulate motivational states. Incentive: an external goal that has the capacity to motivate behaviour. Some incentives may reduce drives but others may not.
