Document Summary

Basic (biological) motives are shared by humans and other animals. Internal physiological need creates an aroused state that drives the organism to reduce the need. Incentives - external events/stimuli that pull us an appropriate direction objects/direction of motivation primary reinforcers (example, sight or smell of food can motivate us) secondary reinforcers (reinforce through learning) Social biology: many animal and human behaviours are inherited. The term has thus been largely dropped in psychology. Pleasure as a basic psychological motivator pleasure is associated with stimuli that enhance our biological well-being pain is associated with events that threaten our survival. Reinforcing consequences of an action determine if it is worth repeating. Pleasure centres of the brain: mesolimbic dopamine system many different stimuli will activate this system perhaps common to all pleasure (food, drink, sex, etc) drugs also activate this system. But, it does may not result in pleasure experience.
