Document Summary

Instinct is an inherited predisposition to behave in a specific and predictable way when exposed to a particular stimulus. They have a genetic basis, are found universally among all members of the species, do not depend on learning and have survival value for the organism. Human instinct theories faded because there was a lack of evidence therefore scientists examine hereditary contributions to human motivation more productively. Modern evolutionary psychologists propose that many psychological motives have evolutionary underpinnings that are expressed through the actions of genes adaptive significance of behaviour is a key to understanding motivation. Homeostasis is a state of internal physiological equilibrium that the body strives to maintain. Maintaining homeostasis requires a sensory mechanism for detecting changes in the internal environment, a response system that can restore equilibrium, and a control centre that receives information from the sensors and activates the response system.
