Switching between habitual and goal-directed actions: A 'two in one' system in our brain

Pressing the button of the lift at your work place, or apartment building is an automatic action -- a habit. You don't even really look at the different buttons; your hand is almost reaching out and pressing on its own. But what happens when you use the lift in a new place? In this case, your hand doesn't know the way, you have to locate the buttons, find the right one, and only then your hand can press a button. Here, pushing the button is a goal-directed action.http://feeds.sciencedaily.com/~r/sciencedaily/~3/-...
