Article: James Cooke, of Islip,N.Y.,can't recognize other people. "I see eyes, nose, cheekbones, but no face," he said. "I've even passed by my son and daughter without recognizing them." He is not the only one. Those with prosopagnosia, also known as face blindness, can see perfectly well, but their brains are unable to piece together the information needed to understand that a collection of features represents an individual's face. The condition is a neurological mystery, but new research has shed light on this strange disease. Some scientists had believed that faces and voices, the two main ways people recognize one another, were processed separately by the brain. Indeed, a condition parallel to prosopagnosia, called _ , similarly leaves a person unable to distinguish a familiar voice from an unfamiliar one. But by testing for these two conditions at the same time, researchers at the Max Planck Institute recently found evidence that face and voice recognition may be linked in a unique person-recognition system. The scientists observed the brain activity of 19 healthy volunteers as they were led through tasks that tested their ability to recognize both faces and voices. The researchers found that regions of the brain, associated with facial recognition, are directly linked to regions responsible for voice recognition. This research helps explain why a person with prosopagnosia may still have difficulty determining who a person is even after he has begun to speak. The challenge for scientists is to find out where this system breaks down. Are these connections in the brain missing entirely, or are people unable to recognize faces and voices simply unable to use these links in some way? It is unclear how many people have these conditions. Many don't even realize they have problems with facial or voice recognition. While some develop these difficulties after a brain injury, others develop it in childhood.

Article: Characters in novels don't always do what the writer wants them to do. Sometimes they cause trouble, take on lives of their own, or even work against the writer. It's not just a problem for inexperienced authors: famed children's novelist Roald Dahl said he got the main character in his bookMatildaso "wrong"that when he'd finished his first version, he threw it away and started again. Of course it's not the characters' fault. The problem lies with the author. Take Stephen King, who admitted that writing working-class characters is more difficult nowadays because his own circumstances have changed. "It is definitely harder,"King said."When I wroteCarriemany years ago, I was one step away from physical labour." This is also true for characters' ages, added King."When you have small children, it is easy to write young characters because you observe them and you have them in your life all the time. But your kids grow up, it's been harder for me to write about this little 12-year-old girl in my new book because my models are gone." For other authors, such as Karen Fowler, there's one quality that can stop a character in its tracks: boredom."I had particular problems with the main character in my historical novelSister Noon,"she says."She had attitudes about race and religion that seemed appropriate to me for her time and class, but they were not attitudes I liked. Eventually I grew quite bored with her. You can write a book about a character you dislike or a character you disagree with, but I don't think you can write a book about a character who bores you." According to Neel Mukherjee, it was Adinath, a character inThe Lives of Others, who made him work the hardest."I think I struggled because it's difficult to write a character whose most prominent personal feature is weakness, as Adinath's is, without making that feature define him,"Mukherjee says. But a troublesome character is far from an unwelcome guest, he continues, arguing that "when characters work against the author they come alive and become unpredictable". "That is a fantastic thing to happen,"Mukherjee says."I celebrate it. It is one of the great, lucky gifts given to a writer."
