Please note that no one here will do your work for you. However, we will be happy to read over what YOU THINK and make suggestions and/or corrections.

Please post what you think.
It depends on how you define normal behavior.

I searched Google under the key words "definitions of normal behavior" to get these possible sources:

http://www.google.com/search?client=safari&rls=en&q=definition+of+normal+behavior+in+psychology&ie=UTF-8&oe=UTF-8

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

Don't just copy the material. Express the ideas in your own words. Although this will take more time and effort, you will learn more.
Thanks :)) I appreciate for the help.
