Instinct is an inherited predisposition to behave in a specific and predictable way when exposed to a particular stimulus. Have a genetic basis, do not depend on learning. Modern evolutionary psychologists propose that many psychological motives have evolutionary underpinnings expressed through the actions of genes. Homeostasis is a state of internal physiological equilibrium that the body strives to maintain.

Homeostatic regulation can also involve learned behaviours. When were hot we not only perspire, but also may seek a shady place or a cool drink.
