A new study suggests that just fingering an item on a store shelf can create an attachment that makes you willing to pay more for it.

Previous studies have shown that many people begin to feel ownership of an item – that it "is theirs" – before they even buy it. But this study, conducted by researchers at Ohio State University, is the first to show "mine, mine, mine" feelings can begin in as little as 30 seconds after first touching an object.

Here is the full story. I thank Deron Bauman for the pointer.
