Doorway to Blame for Room Amnesia
Scientific American: You walk into the kitchen to grab a—wait, why did you come in here again? A new study suggests that your brain is not to blame for your confusion about what you’re doing in a new room—the doorway is. The work is in the Quarterly Journal of Experimental Psychology. [Gabriel A. Radvansky, Sabine A. Krawietz, and Andrea K. Tamplin, "Walking through doorways causes forgetting: Further explorations"] University of Notre Dame researchers had subjects perform memory tasks, such as remembering the colors of blocks in different boxes. The volunteers had to do the task after walking across a room, or after walking the same distance through a doorway into a second room.

The Amygdala As Sales Tool
The Wall Street Journal: Many are the tricks that companies use to win our business. As Martin Lindstrom reminds us in "Brandwashed," marketers make sneaky appeals to our fears and desires, leverage our social connections to maximize peer pressure, dazzle us with tinfoil celebrity and lure us with sexual come-ons that would embarrass a bawd. Mr. Lindstrom has made his living in the business he now proposes to expose. His specialty has been using the tools of brain science to help marketers press subconscious buttons. In 2009, Time magazine named him one of the world's most influential thinkers.

Friday Illusion: Ghostly images change shape
NewScientist: Think hard: you can transform a circle into a hexagon using the power of your mind. New animations created by Hiroyuki Ito from Kyushu University show how staring at coloured shapes can produce an afterimage that varies in form as well as hue. "This is the first study to show systematic shape changes in after-images involving shape processing mechanisms in the brain," says Ito. The first version of the illusion uses solid, stationary shapes. After focusing on yellow circles, blue hexagons typically appear and vice versa. The same effect also occurs with outlines of the shapes. In another variation, hexagons and circles rotate.

Why some people never seem to forget a face
MSN India: Face recognition is an important social skill but not many of us are equally good at it, reveals a study. Researcher Jia Liu along with colleagues from Beijing Normal University have demonstrated how this skill 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,' said Jia, the journal Psychological Science reported. In daily life, we recognize faces both holistically and also analytically - that is, picking out individual parts, such as eyes or nose, according to a university statement.

How finding beauty in ordinary life can make you happy
The Globe and Mail: I have a friend who is next to impossible to go for walk with in the spring or summer. “Look,” she will instruct, stopping dead in her running shoes. “See how beautiful this gladiolus is?” And of course, you have to stop alongside her and admire the texture and the colour and the height of the flowers. What are you, anyway? Some power-walking obsessive who doesn’t know how to smell the proverbial roses? It turns out that identifying and appreciating beauty in the everyday is a happiness strategy. Some spiritual leaders advocate it as a way to feel divine energy.

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.
