English: According to a 2012 study conducted by psychology professor Richard Petty, PhD at the Ohio State University, the way people tag their thoughts ( as valuable or trash ) can make a difference in the way these thoughts are being used. If you want to see how to eliminate negativity thinking using this innovative method, all you have to do is to objectify the negative thoughts using either a text document or a piece of paper and then tossing or dragging it into the trash can. Simply visualizing or imagining the process of throwing them away has no effect; you have you physically toss them in the trash..
