Motivation a general term for a group of phenomena that affect the nature, strength, and persistence of an individual"s behaviour proactive (reinforcement) , reactive biological needs can be very potent motivators. Regulatory systems are characterized by negative feedback loops drive reduction hypothesis the hypothesis that a drive (resulting from physiological need or deprivation) produces an unpleasant state that causes an organism to engage in motivated behaviours. Reduction of drive is assumed to be reinforcing nature of motivation and reinforcement eating reduces hunger this drive reduction is reinforcing. There is no way to measure drive in either of these examples and confirm that it actually exists. The hypothesis cannot be experimentally tested: reinforcing conversation is one that is also exciting, not one that puts you to sleep. Olds and milner showed that electrical stimulation of the brain could be reinforcing to rats it activates the same system that is activated by natural reinforces (drugs)
