Q&A with Catherine Hartley At a special session on the relation between psychology and neuroscience at last year’s CNS conference in San Francisco, Catherine Hartley said: “Even if we can predict behavior, if we don’t know how it works, we likely have not achieved our goals.” While computational algorithms and tools may help researchers predict […]
Revealing the Cognitive Sorcery of Human Intelligence
Q&A with Sam Gershman In the last decade, computational techniques have expanded the toolkit for scientists across disciplines. In neuroscience, computational models are increasingly rendering “visible things that were previously invisible,” says Samuel Gershman, a cognitive neuroscientist at Harvard University. “Computational modeling is not a niche activity. It’s the same theory-building activity in which all […]
Conformity Can Be Good for Your Eating Habits
Cookie or apple? Many of us would choose the cookie if we were by ourselves. But what about around others? If you have ever been at, say, a conference where you see many of your peers choosing an apple, you might choose one as well. New research suggests that this behavioral change also happens on […]
Judging Beauty in Places, Faces
Seeing the new photos of the Pillars of Creation from the Hubble Telescope took my breath away. Beautiful and awe-inspiring. But what was happening in my brain when I looked at them? How and why we react to beauty is something we rarely think about, but neuroscientists are making progress in better understanding these processes. […]
Dissecting the Agony and the Ecstasy of Win-Win Choices
Guest Post by Amitai Shenhav, Princeton University Tonight, after dinner, I will go out for ice cream at one of my favorite spots in Princeton. I will salivate in anticipation of my visit, delighting in all of the options that await me. I will carry that excitement with me as I enter the shop and examine all […]
Running that Red Light? The Complex Drivers of Teenage Risk
You’ve been stuck in traffic forever and are waiting in a long lineup at a red light. The light finally turns green and you start slowly moving, only to find that the light turns yellow as soon as you approach the intersection. Do you go for it and run the yellow (or maybe red!), or […]
Fairness Comes Down to Individual Differences in Gut Reactions
Q&A with Christopher Frith We all want to be treated fairly but some of us care more about fairness than others. How you choose to split money with another person in a game says a lot about your view of fairness, researchers have found. New work reveals how differences in our choices to share resources […]
Pennies for Treats: Dieting Through Brain Training
What’s the first treat you pull out of your candy bag on Halloween? Probably your favorite guilty pleasure… but what if you could use pennies to train yourself to pick a candy you might not like the most but that might be healthier? A new study finds that we may be able to train our […]
How Testosterone Affects Risk-Taking in Adolescent Boys and Girls
Adolescents are infamous for engaging in more risky behavior as they mature from children to adults. This transition is notable for many changes, including a surge in testosterone for both boys and girls. The changing levels of testosterone, combined with the size of a frontal region of the brain, help to explain risk-taking in adolescence, […]
CNS 2013 Meeting: Making Decisions Based on Context: A New Mechanism Gains Traction
The audience for Sunday morning’s keynote lecture at CNS 2013 got to play the part of monkeys during a talk by William Newsome of Stanford University, though our task was a bit easier than what his test monkeys usually experience. Normally, in Newsome’s experiment, monkeys have 750 milliseconds to determine either whether a flashing field […]
