Drive theories
Drives include things like a need for warmth, to eat, or to be thirsty. Drive produces a bad mood and tension that needs to be relieved. Both people and animals look for ways to ease this tension and impelled the organism into activity to procure a reward that reduce the drive and satisfy it's related physiological need.
<h3>What is Drive theory ?</h3>
A drive theory, theory of drives, or drive doctrine is a theory in psychology that aims to describe, categorise, or explain the psychological urges.
- An instinctive urge known as a drive—also known as a "excitatory state induced by a homeostatic disturbance"—can influence an individual's behaviour.
- The idea, in its most basic version, held that no learning took place until a drive created tension and motivated the organism to engage in action in order to obtain a reward that would lessen the drive and meet its associated physiological need.
