You are indeed very far away! But good for you for seeking the knowledge you need to make an outstanding science fair project.
Try reading this document on how to go about finding a mentor; there are many different good ideas here, http://www.sciencebuddies.org/science-f ... tors.shtml
Most professors and professionals are very interested in helping students achieve their potential in science. Be prepared for some of those you ask to not be available or have the time. One way to counter this issue is to ask direct questions, and not too many. When I emailed professors in the past about projects (ones whom I did not know), I kept my questions to a minimum (about 3-5)--that way they could spend about 15-30 minutes answering them and be on their way. I think if you are direct in your questions, people are more willing to answer them.
Check out the American Psychological Association: I don't the resource for your neck of the woods, but you can start here. There are several resources on how to find mentors, as well as links to other Psych. groups
Also, one tool I use is LinkedIn! Create a profile and create a tagline along the lines of: "High school student seeking advice on ___."
Then search "GROUPS" for your interested topic: psychology/ cognitive psychology/ mental health/ human behavior, etc. You can pose questions on the board and several different professionals may answer your questions. I have done this when looking for different types of work and found 2 mentors, two very willing people to give me advice about the topics I was interested in.
Here is one group you might check out:
Hope that helps. Let us know how your search goes, and also remember to ask questions here on the Science Buddies, where we can answer them directly and follow your progress.
