Specific need that triggers a drive and results in goal directed behavior
a feeling that underlies behavior but does not predict behavior well
Complex behaviors that are the similar across a species (Humans do not have them)
Something you require or want
The push to achieve a need
Primary Drives -Hunger Thirst and Sex (biological)

Secondary Drives - Success, Wealth, Fame (learned drives)
Cues in your environment that initiate a need->drive
intrinsic motivation
The reward for the behavior comes from within. You do the behavior because just doing it is fun or the feeling of pride inside of you motivates you to do it. This type of motivation is stronger and will last longer.
extrinsic motivation
You do the behavior to get some other reward. You go to work not for the joy of that job, but to get money. You study not to make yourself a better human, but to get a grade. This is type of motivation is weaker and will fail you eventually.
Drive Reduction Theory
Your body has a need that causes a state of tension resulting in a drive to reduce that tension. You will meet this drive until you reach equilibrium

+explains primary drives
-fails to explain secondary drives
Arousal Theory
At any give moment, you will seek out the excitement/interest (optimum arousal) that is best for your current mood.

+explains secondary drives
-not as good for primary drives
Yerkes Dodson Law
An outgrowth of Arousal Theory
To improve your performance, keep a lower arousal during complex tasks and keep a higher arousal during simple tasks.

Freudian Explanation of Aggression
Aggression is an innate drive that builds up and must be released.
Frustrations (or delays) in our lives is a big source of aggression.
Your hypothalamus monitors fluid levels in your cells and initiates a thirst drive if those levels are too low.
Biological causes of Hunger
Body - stomach contractions
Body Chemicals - High levels of gluclose cause hunger / Low Levels of insulin cause hunger / Low levels of Leptin cause hunger
Brain - lateral hypothalamus causes hunger - the word itself looks hungry thanks to all those skinny l's
Ventromedial hypothalamus tells you to stop eating - the word itself is bigger and doesn't need to eat more.
Environmental causes of Hunger
Cultural influences to Hunger
