In an exclusive preview of his new book, The Stuff of Thought, Steven Pinker looks at language, and the way it expresses the workings of our minds. By analyzing common sentences and words, he shows us how, in what we say and how we say it, we’re communicating much more than we realize
New research at the University of Chicago finds evidence for a clever way that people manage to alleviate the pain of loneliness: They create people in their surroundings to keep them company.
“Biological reproduction is not a very efficient way to alleviate one’s loneliness, but you can make up people when you’re motivated to do so,” said Nicholas Epley, Assistant Professor of Behavioral Science at the University of Chicago’s Graduate School of Business. “When people lack a sense of connection with other people, they are more likely to see their pets, gadgets or gods as human-like.”
People from different cultures use their brains differently to solve the same visual perceptual tasks, MIT researchers and colleagues report in the first brain imaging study of its kind.
Psychological research has established that American culture, which values the individual, emphasizes the independence of objects from their contexts, while East Asian societies emphasize the collective and the contextual interdependence of objects. Behavioral studies have shown that these cultural differences can influence memory and even perception. But are they reflected in brain activity patterns”
Researchers at Duke University have demonstrated that monkeys have the ability to perform mental addition. In fact, monkeys performed about as well as college students given the same test.
The findings shed light on the shared evolutionary origins of arithmetic ability in humans and non-human animals, according to Assistant Professor Elizabeth Brannon, Ph.D. and Jessica Cantlon, Ph.D., of the Duke Center for Cognitive Neuroscience.
Practice makes perfect — or at least that’s what we’re told as we struggle through endless rounds of multiplication tables, goal kicks and piano scales — and it seems, based on the personal experience of many, to be true. That’s why neuroscientists have been perplexed by data showing that at the level of individual synapses, or connections between neurons, increased, repetitive stimulation might actually reverse early gains in synaptic strength. Now, neuroscientists from Carnegie Mellon University and the Max Planck Institute have discovered the mechanism that resolves this apparent paradox. The findings are published in the Jan. 4 issue of Science.
Brain imaging has revealed a breakdown in normal patterns of emotional processing that impairs the ability of people with clinical depression to suppress negative emotional states. Efforts by depressed patients to suppress their feelings when viewing emotionally negative images enhanced activity in several brain areas, including the amygdala, known to play a role in generating emotion, according to a report in the August 15 issue of The Journal of Neuroscience.
MIT neuroscientists exploring how memory formation differs between children and adults have found that although the two groups have much in common, maturity brings richer memories.In the August 5 advance online edition of Nature Neuroscience, the MIT team reports that children rival adults in forming basic memories, but adults do better at remembering the rich, contextual details of that information. The MIT study provides new insights into how children learn that are not only theoretically important, but could also inform practical learning in everyday settings.
