Excerpt from a thoughtful review of Thinking Fast and Slow
It’s impossible to overstate the influence of Kahneman and Tversky. Like Darwin, they helped to dismantle a longstanding myth of human exceptionalism. Although we’d always seen ourselves as rational creatures—this was our Promethean gift—it turns out that human reason is rather feeble, easily overwhelmed by ancient instincts and lazy biases. The mind is a deeply flawed machine.
Nevertheless, there is a subtle optimism lurking in all of Kahneman’s work: it is the hope that self-awareness is a form of salvation, that if we know about our mental mistakes, we can avoid them. One day, we will learn to equally weigh losses and… Continue reading: The Book Bench: Is Self-Knowledge Overrated? : The New Yorker

A teenager’s IQ can rise or fall as many as 20 points in just a few years, a brain-scanning team found in a study published Wednesday that suggests a young person’s intelligence measure isn’t as fixed as once thought.
The researchers also found that shifts in IQ scores corresponded to small physical changes in brain areas related to intellectual skills, though they weren’t able to show a clear cause and effect.

Nicholas Carr has been one of the leading voices in the debate. His book The Shallows, published in June, contends that the Internet is having a detrimental effect, an argument he supports with numerous scientific studies. He says Sparrow’s study "indicates how flexible our brains are in adapting to our tools."
However, he’s not convinced that this adaptation is positive. "It’s critically important to remember that there’s a difference between external memory and internal memory," he says. "If you’re… Continue reading: Evidence Suggests that the Internet Changes How We Remember – Technology Review

“Our memories are changing,’’ said Daniel Wegner, a psychology professor at Harvard and the senior author of the study. “So we remember fewer facts and we remember more sources, which website you saw it on or whose e-mail to look in to find that. . . . It’s like having information at our fingertips makes us always go to our fingertips.’’
The findings, published online by the journal Science, will feel familiar to anyone who has lost Internet access for a matter of hours and felt suddenly helpless or gone through connectivity withdrawal on vacation. But the findings also have broader implications for how we learn, both in the… Continue reading: Internet changing how people recall facts, study suggests – The Boston Globe
Check the article link below for more details and a scary screen shot (via Technology Review, which notes “A series of apps use your brain waves to power them. Welcome to the era of DIY EEG.”)
The company’s first app launched in December. Tug of Mind purports to train users how to relax under pressure. After uploading a headshot — of an ex-boyfriend, say, or a mother-in-law — the photo is transformed into an angry avatar that screams insults (you prerecord the message). The avatar starts smiling if the player remains calm; keep it up and the game is won. Price tag: $4.99.
Both games require a headset that reads brain waves,… Continue reading: Mind controlled apps hit the market | Technology | Los Angeles Times
