Document Summary

Explain the factors involved in motivating our behaviour. Motivation: the desires (internal and external), needs, and interests that arous and activate an organisms to move towards a specific goal. Affects the nature, strength, and persistence of an individual"s behaviour. Describe the terms motivation and drive and differentiate between regulatory and nonregulatory drives. Drive: a reversible internal condition that orients the individual towards a specific type of goal. Regulatory drive: hunger, thirst, thermoregulation, and sleep that maintain physiological homeostasis and are needed for our immediate survival. Nonregulatory drives: evolutionary purposes, but indirectly; such as reproduction, safety, social cooperation, play, and exploration. Describe how researchers have identified reward systems in the brain. Rats will quickly press a level for electrical stimulation of the brain (esb) for a brief electrical current that delivers an electrode implanted into their brain. It shows that animals can be motivated by rewards that have no obvious value for survival and drive reduction.
