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.

How Impatience Kills Your Credit Score
Forbes: Everything seems to come back to marshmallows in the end. You may recall the famous 1972 Stanford psychology study, conducted by Walter Mischel, in which a group of kids were presented with a plate of marshmallows and told that if they could wait and not eat them now, they’d get a better reward later. When the adults left the room, some of the kids stuffed marshmallows into their mouths with abandon, while others fought back the urge and waited it out.

Study: Vaccines & Hand-Washing Can Reduce Prejudice Against Immigrants, the Obese & Crack Addicts
Discover Magazine: The war between people and disease-causing pathogens is old as humanity itself. This has helped shaped our so-called behavioral immunity, which can lead us, for example, to automatically avoid people who are visibly sick. But it can also misfire; previous studies have shown that people with compromised immune systems (due to a recent illness), and even people who describe themselves as afraid of germs or susceptible to disease, are more likely to avoid and feel prejudiced toward otherwise healthy people who merely look different than them, like foreigners or immigrants.

Q & A With Psychological Scientist Daniel Levitin (Part 1)
Daniel Levitin, a prominent psychological scientist, musician, author and producer, will be speaking at the 24th Annual APS Convention in Chicago this May as part of the Music, Mind, and Brain Theme Program. We invited Twitter and Facebook followers to ask Levitin questions based on his background and research in music and psychology. Here is what Levitin had to say... You've played in rock bands, and you've pioneered the academic study of music. Does music shape your intellectual work, or vice versa? Can you give an example of this? Well first, I'd like to say that as much as I appreciate the compliment, I'm really not a pioneer in the academic study of music.

Waking up to caffeine
Chicago Tribune: A few years ago, when Illinois Institute of Art student Alex Smyth was a hard-core competitive video gamer, caffeine was the elixir that fueled his all-night Halo rampages. He chugged a dozen energy drinks a day and never felt any ill effects, he said. "I love caffeine," said Smyth, 21, who has since moved on to coffee. "It makes me live." He's far from alone in his affection for the world's most beloved stimulant: In North America alone, some research has concluded, up to 90 percent of adults say they consume caffeine regularly. Yet for centuries, it has been occasionally attacked as an unhealthy — even immoral — substance. Read the whole story: Chicago Tribune

The perfect gift
The Boston Globe: The high season of gifts is now upon us, and it is time to face a few uncomfortable truths: You do not know what most of the people on your list will actually enjoy. The majority of your gifts will be something of a failure. In fact, your whole concept of what makes a gift thoughtful — of what will be appreciated — is almost certainly wrong. There is, however, good news: You can do better, and it’s not that hard. First, though, consider the evidence of our gifting flops. When polled, almost half of all Americans predict they will be disappointed enough to return a holiday gift, and perhaps several.
