In this article, researches hypothesize how the expansion of dopaminergic systems may have contributed to the development of many of our unique cognitive abilities including language.

Got turned onto this course at the recent "Learning and the Brain" conference in San Francisco, as one of the presenters, Mary-Helen Immordino-Yang, an affective neuroscientist and human development psychologist, is one of the co-developers of this introductory neuroscience course: free, thanks to a generous Annenberg Foundation grant. The course units cover several topics pertinent to Words R Us, including brain anatomy; language, music, and the brain; language and brain damage; emotions, empathy, and behavior; and cognitive functioning and development as it relates to reading and writing. The site also offers lots of embedded course materials, visuals, and videos. Though originally geared towards K-12 teachers, other educators, researchers, and adult learners who want to learn more about current issues in education, students-especially those considering careers in education, psychology, neuroscience, and/or the biological sciences-might find this course useful.

The article recaps several studies suggesting that the habits encouraged by mobile technology - namely, talking in public to someone who is not there - are tailor made for hijacking the cognitive functions of bystanders.

Language in humans has evolved culturally rather than genetically, according to a new study. By modeling the ways in which genes for language might have evolved alongside language itself, the study showed that genetic adaptation to language would be highly unlikely, as cultural conventions change much more rapidly than genes. Thus, the biological machinery upon which human language is built appears to predate the emergence of language. Professor Nick Chater, University College London Cognitive, Perceptual and Brain Sciences, says: "...although we have appear to have a genetic predisposition towards language, human language has evolved far more quickly than our genes could keep up with, suggesting that language is shaped and driven by culture rather than biology. The linguistic environment is continually changing; indeed, linguistic change is vastly more rapid than genetic change. "

Read this full article: "seems" is the operative word, as linguists are NOT in agreement that language definitively shapes how we see the world. If you want to learn another language and become fluent, you may have to change the way you behave in small but sometimes significant ways, specifically how you sort things into categories and what you notice. Researchers are starting to study how those changes happen, says Aneta Pavlenko, a professor of linguistics at Temple University. If people speaking different languages need to group or observe things differently, then bilinguals ought to switch focus depending on the language they use. That's exactly the case, according to Pavlenko. For example, she says English distinguishes between cups and glasses, but in Russian, the difference between chashka (cup) and stakan (glass) is based on shape, not material. One's native language could also affect memory, says Pavlenko. She points to novelist Vladimir Nabokov, who was fully trilingual in English, French and Russian. When Nabokov started translating his first memoir, written in English, into Russian, he recalled a lot of things that he did not remember when writing it in English. Pavlenko states that "the version of Nabokov's autobiography we know now is actually a third attempt, where he had to recall more things in Russian and then re-translate them from Russian back into English." Lena Boroditsky, an associate professor of cognitive science at the University of California, San Diego, has studied the differences in what research subjects remember when using English, which doesn't always note the intent of an action, and Spanish, which does. This can lead to differences in what people remember seeing, which is potentially important in eyewitness testimony, she says. However, not all linguists agree that language affects what we notice. John McWhorter,, a linguist at Columbia University, acknowledges such differences but says they don't really matter. The experim

(This article was by my college friend, Quinn Eastman, who's a trained scientist and science writer for Emory University.) Listening to metaphors involving arms or legs loops in a region of the brain responsible for visual perception of those body parts, scientists have discovered. The finding, recently published in Brain & Language, is another example of how neuroscience studies are providing evidence for "grounded cognition" - the idea that comprehension of abstract concepts in the brain is built upon concrete experiences, a proposal whose history extends back millennia to Aristotle. When study participants heard sentences that included phrases such as "shoulder responsibility," "foot the bill" or "twist my arm", they tended to engage a region of the brain called the left extrastriate body area or EBA. The same level of activation was not seen when participants heard literal sentences containing phrases with a similar meaning, such as "take responsibility" or "pay the bill." The study included 12 right-handed, English-speaking people, and blood flow in their brains was monitored by functional MRI (magnetic resonance imaging). "The EBA is part of the extrastriate visual cortex, and it was known to be involved in identifying body parts," says senior author Krish Sathian, MD, PhD, professor of neurology, rehabilitation medicine, and psychology at Emory University. "We found that the metaphor selectivity of the EBA matches its visual selectivity." The EBA was not activated when study participants heard literal, non-metaphorical sentences describing body parts. "This suggests that deep semantic processing is needed to recruit the EBA, over and above routine use of the words for body parts," Sathian says. Sathian's research team had previously observed that metaphors involving the sense of touch, such as "a rough day", activate a region of the brain important for sensing texture. In addition, other researchers have shown t

BEING bilingual has some obvious advantages. Learning more than one language enables new conversations and new experiences. But in recent years, psychology researchers have demonstrated some less obvious advantages of bilingualism, too. For instance, bilingual children may enjoy certain cognitive benefits, such as improved executive function - which is critical for problem solving and other mentally demanding activities.

Recently, people have been returning to writing basics: handwriting, notebooks, pens, paper, and stationary. While technology can certainly provide an edge for certain tasks, digital overload, addiction, and distraction are growing concerns. many studies indicate that multitasking is bad for us and makes our brains more scattered. In contrast, several studies suggest that pen and paper have an edge over the keyboard. In three studies, researchers found that students who took notes on laptops performed worse on conceptual questions than students who took notes longhand. Those who took written notes had better comprehension and retention of material because they had to mentally process information rather than type it verbatim. And, another study, published in the Journal of Applied Cognitive Psychology, showed that people who doodle can better recall dull information. Writing it down also sparks innovation. Being innovative and creative is about "getting your hands dirty" a feeling that is lacking when you use technology or gadgets, says Arvind Malhotra, a professor at the University of North Carolina Kenan-Flagler Business School."Research has also shown that tactile sensory perceptions tend to stimulate parts of the brain that are associated with creativity. So, touch, feel and the sensation you get when you build something physical has also got a lot to do with creativity," he says.

If you've ever forgotten a word just as you were about to say it, you've experienced the Tip-of-the-Tounge phenomenon. Tip-of-the-tongue phenomenon is the subjective feeling that people have of being confident that they know the target word for which they are searching, yet they cannot recall this word. Tip-of-the-tongue phenomenon is one kind of metacognition (meaning you are aware of you're cognitive processes), that involves a feeling of knowing the word you're searching for. This phenomenon appear to occur when one is having a breakdown in the intermediate stage of lexical retrieval.

Cognitive neuroscientists warn that humans may be developing digital brains with new circuits for skimming through the torrent of information online. This alternative way of reading is competing with traditional deep reading circuitry developed over several millennia.

For decades, psychologists cautioned against raising children bilingual. They warned parents and teachers that learning a second language as a child was bad for brain development. But recent studies have found exactly the opposite. Researchers now believe that when people learn another language, they develop cognitive advantages that improve their attention, self-control and ability to deal with conflicting information.

Raising bilingual children is actually good for them. They develop a better ability to concentrate and deal with conflicting information. This could indicate that nurturing a child's brain can increase their language capabilities.

This article explores the role of the human language gene (FOXP2) in mice and how it has affected them cognitively.

For bilinguals, because both languages are active in the brain, the act of keeping the two languages separate sharpens the executive control system. Strengthening this area may have long-term benefits: namely, performing better on a variety of cognitive tasks and possibly delaying the onset of dementia later in life.

Being able to speak two languages isn't just useful for traveling to other countries -- it could actually help keep your brain in tip-top shape in older age, a new study suggests.
