Document Summary

Describe the terms motivation and drive, and differentiate between regulatory and non-regulatory drives. Describe the rewards systems and mechanisms in the brain. Analyze the pleasure principle and the hedonic nature of motivation. Evaluate the drive-reduction theory and the optimum-level hypothesis. Evaluate theories of motivation for their ability to explain how and why we eat. Motivation: general term for phenomena that affect the nature, strength, and persistence of an individual. Drive: a reversible internal condition that effects your motivation level. Drives can be classified as regulatory (needed for immediate survival) or non-regulatory (which satisfy some other evolutionary purpose like safety, reproduction, cooperation) Non-regulatory drives include safety, reproduction, social, and educative. The rewards system reinforces behaviours that result in the reduction of a drive, this is related to the limbic system in the basal forebrain (idle, behind ears) Animals can be motivated by rewards even if they have no obvious value for survival and drive reduction.
