Psychopathy: A Misunderstood Personality Disorder
Psychopathic personalities are some of the most memorable characters portrayed in popular media today. These characters, like Patrick Bateman from American Psycho, Frank Abagnale Jr. from Catch Me If You Can and Alex from A Clockwork Orange, are typically depicted as charming, intriguing, dishonest, guiltless, and in some cases, downright terrifying. But scientific research suggests that psychopathy is a personality disorder that is widely misunderstood. “Psychopathy tends to be used as a label for people we do not like, cannot understand, or construe as evil,” notes Jennifer Skeem, Professor of Psychology and Social Behavior at the University of California, Irvine.

Why Aren’t We Smarter Already? Evolutionary Limits on Cognition
We put a lot of energy into improving our memory, intelligence, and attention. There are even drugs that make us sharper, such as Ritalin and caffeine. But maybe smarter isn’t really all that better. A new paper published in Current Directions in Psychological Science, a journal of the Association for Psychological Science, warns that there are limits on how smart humans can get, and any increases in thinking ability are likely to come with problems. The authors looked to evolution to understand about why humans are only as smart as we are and not any smarter.

Can Companies, Political Groups or Organizations Have a Single Mind?
News of employee misconduct always creates a whirlwind for the companies involved — think of Enron, Goldman Sachs and UBS, for example. But are these firms responsible for the actions of their employees? Or do individual members have distinct and independent responsibility separate from a group’s actions? New research from the Kellogg School of Management at Northwestern University and Boston College find that members of a cohesive group are judged to have less responsibility for their own individual actions.

Where Is the Accurate Memory? The Eyes Have It
The witness points out the criminal in a police lineup. She swears she’d remember that face forever. Then DNA evidence shows she’s got the wrong guy. It happens so frequently that many courts are looking with extreme skepticism at eyewitness testimony. Is there a way to get a more accurate reading of memory? A new study says yes. “Eye movements are drawn quickly to remembered objects,” says Deborah Hannula, assistant professor at the University of Wisconsin Milwaukee, who conducted the study with Carol L. Baym and Neal J. Cohen of the University of Illinois, Urbana-Champaign and David E. Warren of the University of Iowa College of Medicine.

Even Unconsciously, Sound Helps Us See
"Imagine you are playing ping-pong with a friend. Your friend makes a serve. Information about where and when the ball hit the table is provided by both vision and hearing. Scientists have believed that each of the senses produces an estimate relevant for the task (in this example, about the location or time of the ball's impact) and then these votes get combined subconsciously according to rules that take into account which sense is more reliable. And this is how the senses interact in how we perceive the world.

Why Do Some People Never Forget A Face?
“Face recognition is an important social skill, but not all of us are equally good at it,” says Beijing Normal University cognitive psychologist Jia Liu. But what accounts for the difference? A new study by Liu and colleagues Ruosi Wang, Jingguang Li, Huizhen Fang, and Moqian Tian provides evidence that the inequality of abilities is rooted in the unique way in which the mind perceives faces. “Individuals who process faces more holistically”—that is, as an integrated whole—“are better at face recognition,” says Liu. The findings will appear in an upcoming issue of Psychological Science, a journal published by the Association for Psychological Science.
