Study guide answer exam 1
Below is a study guide for Exam #1. Keep in mind that I am looking at your exam questions while writing the study guide. Be sure you know what the terms are, how they have been researched, and describe your answers in your own words. I decided to limit your test to the first three chapters. You can do quite well focusing on the material below. Enjoy!
Why is drug withdrawal a painful experience for addicts?
Using drugs puts an excess amount of neurotransmitters in the body. When there is an overflow the brain stops making it naturally and when the drug wears off it takes time for the brain to star making the chemical once again on its own system. Some neurotransmitters are dopamine, serotonin, Acetylcholine, Norepinephrine, Gamm-amniobutyric acid, Endorphins. Endorphins are natural opiates.

What does it mean to be randomly assigned?
The design of a study such that all subjects have an equal chance of being assigned to any group or condition.
What does it mean to be debriefed?
A discussion of procedures, hypothesis. And subject reactions at the completion of the study.

A correlation exists when 2 variables are related to each other. May be positive or negative depends on nature of the association between the variables measured. Correlation indicates the 2 variables that change together in the opposite direction. Strength of correlation depends on size of coefficient.
Be very clear about the difference between correlation and causation.

What is an independent and dependent variable?
What do we know about Alzheimer’s disease, schizophrenia and neurotransmitters?
Alzheimer’s brains show to have low levels of ACH-Acetylcholine. Schizophrenia is linked to excess levels of dopamine.
