Liars’ Brains Wired Differently

While previous research has shown that there is heightened activity in the prefrontal cortex - the area of the brain that enables most people to feel remorse or learn moral behavior - when normal people lie, this is the first study to provide evidence of structural differences in that area among pathological liars.

Dictionary of global linguistic curios brings words for every occasion

Filed under: Lexicography

Ever needed that elusive word to describe a fear of having no beer? Or for a woman who looks pretty from the back but not the front? Help is at hand from a new book rounding up the world’s most specialised lexicon. “The Meaning of Tingo,” by British author Adam Jacot de Boinod, is somewhat of a labour of love, resulting from a year of solid trawling through 280 dictionaries and many dozens of Internet sites.

Requirement For High-level Mental Processing In Subliminal Learning

We are constantly learning new things as we go about our lives. In addition to learning new facts, procedures, and concepts, we are also refining our sensory abilities. How and when these sensory modifications take place is the focus of intense study and debate. In new work, researchers at Boston University and the University of Montreal unify two lines of research–our understanding of classical learning and a phenomenon known as the attentional blink–to achieve an important demonstration that high-level mental processing is required even for subliminal learning.

Words ‘can change what we smell’

A rose by any other name might not smell as sweet, UK research suggests. But labelling an unpleasant smell with a more appealing name can improve its aroma, an Oxford University team has found.

Babies Use Rhythms to Adapt to Their Culture, Study Hints

Filed under: Language acquisition

By the time babies celebrate their first birthday, their ears are already tuned to the rhythms and sounds of their culture, researchers say. The finding suggests that one-year-olds in North America, for example, notice subtle changes in waltz-like rhythms but not in the complex dance rhythms unique to other continents.

Evolutionary Tools Help Unlock Origins of Ancient Languages

The key to understanding how languages evolved may lie in their structure, not their vocabularies, a new report suggests. Findings published today in the journal Science indicate that a linguistic technique that borrows some features from evolutionary biology tools can unlock secrets of languages more than 10,000 years old.

New online atlas provides collective maps of human brain folds

Neuroscientists at Washington University School of Medicine in St. Louis have assembled a first-of-its kind atlas of the folds of the cerebral cortex, the wrinkled surface layer of the brain credited with many of the higher cognitive functions that make us human. The atlas, known as the Population-Average, Landmark and Surface-based (PALS) Atlas, links brain functions to the various peaks and valleys of the cortex.

Almost before we spoke, we swore

Filed under: Language in society

The United States Senate is poised to consider a bill that would sharply increase the penalty for obscenity on the air, seeking to return to the public square the gentler tenor of yesteryear, when seldom were heard any scurrilous words, and famous guys were not foul mouthed all day. Yet researchers who study the evolution of language and the psychology of swearing say that they have no idea what mystic model of linguistic gentility the critics might have in mind. Cursing, they say, is a human universal.

Psychologists at Harvard University have found that five-year-olds are able to grasp numeric abstractions and arithmetic concepts even without the formal education or language to express this knowledge in words. The discovery of these inborn skills among preschoolers could point the way to new teaching techniques, making arithmetic easier and more pleasant for elementary school children.
