How much math (and what courses) are required for an undergraduate psychology major?

I’ll be a freshman in college next fall (2013) and I plan to major in psychology. I am not the smartest individual at math and sometimes it takes me awhile to grasp concepts, so I was wondering how much math I would be required to take and what math courses they would be. I am hoping to be admitted to The University of Texas at Austin and have tried looking this up, but with no luck. Also, I want to earn my PhD in psychology so does that affect requirements?
