OS X :: Changing Two Finger Swipe Direction On Macbook?

I've had an iPhone for the last few years and am used to the direction of swiping on the iPhone. I recently purchased a macbook pro and noticed that the scrolling on the iPhone and Macbook occur in the opposite direction when scrolling from top to bottom and it's driving me crazy. I'm looking for a way to change the direction that the window moves when using the two finger swipe on my macbook pro.

When scrolling though web pages on the iPhone, sliding your finger from the top of the phone to the bottom displays text above the current viewing window. In other words, if I place my finger over a word and move my finger up or down my finger is still on top of the word when I'm done scrolling. Scrolling on the track pad of my macbook pro works in the opposite direction. On the macbook when I swipe two fingers from the top to the bottom of the track pad the text above the current window is shown. If I put my cursor over a word and two finger swipe the word moves in the opposite direction as my fingers. I would like to change this behavior so that scrolling occurs in the same manner that it does on the iPhone.
