I feel like I should say this because I wish someone had said it to me.
I understand exactly where you are coming from acidicspecies08. Let me preface this with a description of myself: I am currently an senior undergraduate. I have a 3.70 cum GPA, and 3.8 psych GPA. I had a 670 vebal 760 math GRE. I am Psi Chi, and have done research with one professor, designed an implemented a study when I was abroad, and am currently doing a thesis. I also worked at an in-patient clinic for eating disorders for one summer. I was a resident advisor, and then was put in charge of a staff of 7 resident advisors. I spent two semesters as a TA. My Recommendations were awesome. There was never doubt in my mind, my advisers' minds, my friends' or families' minds that I would get into a program. There was never any doubt even though I was applying to only top-tier PhD programs- I am well within what they are looking for. (Sorry, that sounds like I am bragging).
I only got one interview.
I suppose I could be wrong, but I am beginning to come to the conclusion that grad schools REALLY dont like people straight out of undergraduate. They want people to take a break and get some real-life experience; they want us to figure things out. Now, for people like you and me, that is really annoying. We know what we want and a year or two isnt going to change that. If you are like me, you also know that you wont burn out with 6 more years of academics. However, schools don't know this. The majority of people who apply straight out of college might not be ready for another 6 years of school. I don't know their reasons- but many of the people I have talked to in graduate school mention that there are virtualy no people straight out of college.
However, there is something to be said for taking time off. You can get more experience in the field you are interested in. You can do what I plan to do and just travel.
Additionally, think of this. Graduate school MATTERS. Going to the best one you can is really important. They will train you, mold you, influence you, and that training will affect your life. That is why I did not apply to any "saftey schools." I know that given 2 years I will be able to get into the majority of the schools on my list. Why not improve your standing as a candidate by taking one year off? Rest, relax, and dont add the stress of applications to your senior year. Or try for programs you would really LOVE to go to (rather than just be satisfied at) and then take it from there.
If at first you dont succeed, try try again has become my new motto.
I just thought you should keep that in mind. This application process is weird. I don't understand it. But I understand it a little more now that I have suffered through.
Whatever you decide- good luck!
