The section that I chose to read was Reading 23: Watching your emotions. Pages 175-180. This study was a recent study that is representative of research that is in the process of changing psychology in potentially compelling ways. Research article was listed as Mind readers by Philip Ross that was in the Scientific American August 11, 2003. 289(3), 74-77. The purpose for this study was . This was a seemingly small exploratory study that used an MRI machine to scan the brains of the participants while they were lying or telling the truth to show the brains activity. There were two sections of participants whos ages were not specified. One group of participants were asked to select one of three envelopes, all of which contained the 5 of clubs and a $20 bill. (they did not know that all of the contents were the same). Then they were asked to memorize the card and return all of the contents into the envelope and conceal it in their pocket. If they could successfully keep the card a secret from a "Computer" that could analyze their thoughts then they could keep the $20 bill. The other group of participants received the 2 of hearts and were instructed to tell the truth and not conceal what card they had. Each participant was then put into the fMRI (functional MRI) with access to a YES or NO button. They were then asked if they had a particular card. The researchers knew the answer but the participants did not know that. The results of the study were clear. The ones who told the truth utilized only one region of the brain, while the ones who lied utilized two regions of the brain. The significance of this study was mentioned by Hock as 1.) To demonstrate how MRI scanning may have importance
