Workers in the digital era can feel at times as if they are playing a video game, battling the barrage of e-mails and instant messages, juggling documents, Web sites and online calendars. To cope, people have become swift with the mouse, toggling among dozens of overlapping windows on a single monitor.
But there is a growing new tactic for countering the data assault: the addition of a second computer screen. Or a third…
David E. Meyer, a psychology professor at the University of Michigan whose research has found that multitasking can take a serious toll on productivity… Warned that productivity can suffer when people keep interrupting their thoughts by scanning multiple screens rather than focusing on one task.

Crosswords can reflect the nature of intuition, hint at the way we retrieve words from our memory and reveal a surprising connection between puzzle-solving and our ability to recognize a human face.
“What’s fascinating about a crossword is that it involves many aspects of cognition that we normally study piecemeal, such as memory search and problem-solving, all rolled into one ball,” says Raymond Nickerson, a psychologist at Tufts University. In a paper published last year, he analyzed the mental processes of crossword-solving.

The author of “On Being Certain” and the coming “A Skeptic’s Guide to the Mind,” Dr. [Robert A.] Burton is a contributor to a scholarly yet surprisingly sprightly volume called “Pathological Altruism,” to be published this fall by Oxford University Press. And he says his colleague’s behavior is a good example of that catchily contradictory term, just beginning to make the rounds through the psychological sciences.
As the new book makes clear, pathological altruism is not limited to showcase acts of self-sacrifice, like donating a kidney or a part of one’s liver to a total stranger. The book is the first comprehensive treatment of the idea that when ostensibly generous “how can I help you?” behavior is taken to extremes, misapplied or stridently rhapsodized, it can become unhelpful, unproductive and even destructive.
Medical Xpress reports:
In a study to be published Sept. 1 in Nature, Stanford University School of Medicine scientists have found substances in the blood of old mice that makes young brains act older. These substances, whose levels rise with increasing age, appear to inhibit the brain’s ability to produce new nerve cells critical to memory and learning.
The findings raise the question of whether it might be possible to shield the brain from aging by eliminating or mitigating the effects of these apparently detrimental blood-borne substances, or perhaps by identifying other blood-borne substances that exert rejuvenating effects on the brain but whose levels decline with age…

Behind every smart web service is some even smarter web code. From the web retailers – calculating what books and films we might be interested in, to Facebook’s friend finding and image tagging services, to the search engines that guide us around the net.
It is these invisible computations [computer algorithms] that increasingly control how we interact with our electronic world.
At last month’s TEDGlobal conference, algorithm expert Kevin Slavin delivered one of the tech show’s most “sit up and take notice” speeches where he warned that the “maths that computers use to decide stuff” was infiltrating every aspect of our lives.
