For decades, scientists thought perhaps smell was a diminished human sense and less valuable than other senses - like our glorious eyesight. "In the West, people came to this conclusion [through] the fact that we don't seem to have a good ability to talk about smells," says Asifa Majid, a professor of language and cultural cognition at Radboud University in the Netherlands. But Majid found that isn't universally true. Certain language speakers can name odors as easily as English speakers name colors, and the key difference may be how they live. Majid worked with speakers of four different languages: English and three from the Malay Peninsula. Two of these languages, Semaq Beri and Jahai, are spoken by hunter-gatherer groups. The other one, Semelai, is spoken by farmers. In order to test the ability of these language speakers to classify odors, Majid and her colleagues gave asked them to smell pen-shaped contraptions each filled with a different scent like leather, orange, garlic or fish - and then asked them to identify the smell. She also asked the participants to identify colors using different color chips. The farmer Semelai, like English speakers, found colors relatively easy to name and agreed with one another that the red chips were, indeed, red. When it came to identifying odors, the Semelai failed as miserably as the English speakers on the same tests. But both hunter-gatherer groups were much better at naming smells than the Semelai. In fact, they were just as good at identifying smells as colors. "That says something about the hunter-gatherer lifestyle," Majid says. There's a scarcity of English words that objectively describe odors, Majid says. Given that, readers of this article - written in English - may wonder how it's possible to describe a smell without leaning on other senses like taste (words like "sweet" or "sour") or emotional words like "gross." In English, most of our attempts to describe smells come from individual sources. You

Recognition of subtle emotional cues may be developmental, according to neurological research. At the McLean Hospital in Belmont, Mass., Deborah Yurgelun-Todd and a group of researchers have studied how adolescents perceive emotion as compared to adults. The scientists looked at the brains of 18 children between the ages of 10 and 18 and compared them to 16 adults using functional magnetic resonance imaging (fMRI). Both groups were shown pictures of adult faces and asked to identify the emotion on the faces. Using fMRI, the researchers could trace what part of the brain responded as subjects were asked to identify the expression depicted in the picture. The results surprised the researchers. The adults correctly identified the expression as fear. Yet the teens answered "shocked, surprised, angry." Moreover, teens and adults used different parts of their brains to process what they were feeling. The teens mostly used the amygdala, a small almond shaped region that guides instinctual or "gut" reactions, while the adults relied on the frontal cortex, which governs reason and planning. As the teens got older, however, the center of activity shifted more toward the frontal cortex and away from the cruder response of the amygdala. Yurgelun-Todd, director of neuropsychology and cognitive neuroimaging at McLean Hospital believes the study goes partway to understanding why the teenage years seem so emotionally turbulent. The teens seemed not only to be misreading the feelings on the adult's face, but they reacted strongly from an area deep inside the brain. The frontal cortex helped the adults distinguish fear from shock or surprise. Often called the executive or CEO of the brain, the frontal cortex gives adults the ability to distinguish a subtlety of expression: "Was this really fear or was it surprise or shock?" For the teens, this area wasn't fully operating.

'By studying language in people with aphasia, we can try to accomplish two goals at once: we can improve our clinical understanding of aphasia and get new insights into how language is organized in the mind and brain,' said Daniel Mirman, Professor of Psychology at Drexel University. Mirman is lead author of a new study which examined data from 99 people who had persistent language impairments after a left-hemisphere stroke. In the first part of the study, the researchers collected 17 measures of cognitive and language performance and used a statistical technique to find the common elements that underlie performance on multiple measures. Researchers found that spoken language impairments vary along four dimensions or factors: 1. Semantic Recognition: difficulty recognizing the meaning or relationship of concepts, such as matching related pictures or matching words to associated pictures. 2. Speech Recognition: difficulty with fine-grained speech perception, such as telling "ba" and "da" apart or determining whether two words rhyme. 3. Speech Production: difficulty planning and executing speech actions, such as repeating real and made-up words or the tendency to make speech errors like saying "girappe" for "giraffe." 4. Semantic Errors: making semantic speech errors, such as saying "zebra" instead of "giraffe," regardless of performance on other tasks that involved processing meaning. In the second part of the study, researchers mapped the areas of the brain associated with each of the four dimensions identified above.

Recent studies may reveal that the advantages of bilingualism arise with any combination of language varieties that differ enough to challenge the brain. They could be dialects of the same language, two related languages such as Italian and Spanish, or as diverse as English and Mandarin Chinese. Systematically switching between any two forms of language, even quite similar ones, seems to provide the mind with the extra stimulation that leads to higher cognitive performance. What our research suggests - contrary to some widely held beliefs - is that, when it comes to language, plurality is an advantage and in this respect dialects are under-recognised and undervalued. This kind of research can make people appreciate there is an advantage to bi-dialectalism - and this may be important when we think about our identity, how we educate children and the importance of language learning.

This is from assistant professor Lera Boroditsky at Stanford University. She talks about how her research can show how language can shape the way that we think about time, shapes, space, colors and obejcts. "Language is central to our experience of being human, and the languages we speak profoundly shape the way we think, the way we see the world, the way we live our lives."

which cognitive faculty would you most hate to lose? Most people would say sight or hearing, but what would your life be like if you had never learned a language? But are languages merely tools for expressing our thoughts, or do they actually shape our thoughts?

How different languages shape the way people who speak that language think. Lera Boroditsky has done studies on the Kuuk Thaayorre, an Indigenous Australian group who instead of using words like "left" or "right," they use cardinal directions (North, South, East, West). Because of how they use cardinal directions, the Kuuk Thaayorre are very oriented.

Nice overview of the neurological and other benefits conferred by bilingualism. Being fluent in two languages, particularly from early childhood, not only enhances a person's ability to concentrate, but might also protect against the onset of dementia and other age-related cognitive decline. More recently, scientists have discovered that bilingual adults have denser gray matter (brain tissue packed with information-processing nerve cells and fibers), especially in the brain's left hemisphere, where most language and communication skills are controlled. The effect is strongest in people who learned a second language before the age of five and in those who are most proficient at their second language. This finding suggests that being bilingual from an early age significantly alters the brain's structure.

You only use 10 percent of your brain. Eating carrots improves your eyesight. Vitamin C cures the common cold. Crime in the United States is at an all-time high. None of those things are true. But the facts don't actually matter: People repeat them so often that you believe them. Welcome to the "illusory truth effect," a glitch in the human psyche that equates repetition with truth. Marketers and politicians are masters of manipulating this particular cognitive bias. "Repetition makes things seem more plausible," says Lynn Hasher, a psychologist at the University of Toronto whose research team first noticed the effect in the 1970s. "And the effect is likely more powerful when people are tired or distracted by other information."

Recent History of Our Struggle to Make Foreign Languages Core Foreign language study is in the national education Goals 2000, which states: "By the year 2000 all American students will leave grades 4, 8, and 12 having demonstrated competency in challenging subject matter including English, mathematics, science, foreign language, civics and government, arts, history, and geography..."

The age at which children learn a second language can have a significant bearing on the structure of their adult brain, according to a new joint study by the Montreal Neurological Institute and Hospital -- The Neuro at McGill University and Oxford University. The study concludes that the pattern of brain development is similar if you learn one or two language from birth. However, learning a second language later on in childhood after gaining proficiency in the first (native) language does in fact modify the brain's structure, specifically the brain's inferior frontal cortex. The left inferior frontal cortex became thicker and the right inferior frontal cortex became thinner. The cortex is a multi-layered mass of neurons that plays a major role in cognitive functions such as thought, language, consciousness and memory. The study suggests that the task of acquiring a second language after infancy stimulates new neural growth and connections among neurons in ways seen in acquiring complex motor skills such as juggling. The study's authors speculate that the difficulty that some people have in learning a second language later in life could be explained at the structural level.

"...people who speak more than one language don't exhibit symptoms of Alzheimer's disease until they have twice as much brain damage as unilingual people. It's the first physical evidence that bilingualism delays the onset of the disease. ... Despite the fact that both groups performed equivalently on all measures of cognitive performance, the scans of the bilingual patients showed twice as much atrophy in areas of the brain known to be affected by Alzheimer's."

While brain games can't avert dementia in those genetically inclined toward the condition, one can ensure better brain fitness and long-term health. The brain thrives on continuous stimulation. Here are takeaway tips from the article: 1. Brain exercises should rely on novelty and complexity, including board games that are played with others. 2. All kinds of concentrated activities, like learning a foreign language or how to play a musical instrument, can be fulfilling. 3. Along with exercising and good nutrition, a brain that is fully engaged socially, mentally and spiritually is more resilient. 4. New, interactive learning is helpful. 5. Cognitive training that uses thinking, such as problem solving and learning, like reading a newspaper article and discussing it with a friend, has staying power in the brain - even 10 years after the training ends.

A linguist who began to train her border collie for sheepdog competitions using a dog whistle realized that the commands reminded her of language. The article goes on to detail communication between dogs and people, and how dog's cognition and understanding goes past following basic commands. For example, Chaser, the border collie, was able to fast map and learn things through reference cues - which goes much farther past simply understanding commands. It turns out, shepherds use only a few whistle commands with their sheepdogs, but the whistles change meaning based on situation, pitch, speed, etc, and provide information to the dog, similar to prosody, a key part of human language.

Almost every language on the planet includes words that sound like the things they describe. Crash, yawn, glug… speech is just full of these onomatopoeias. And because they have their root in real things they're often easy to identify. Even a non-native speaker might recognise the Hindi "achhee" (a sneeze) or the Indonesian "gluk" (glug). Because these onomatopoeias are so widely encountered, easy to pick up, and convey information might they be the first form of language? That's the argument presented in a recent paper published in Animal Cognition. It points out that our ancestors would have begun encountering more and more noises that we could repeat. Tool use/ manufacture in particular, with its smashes and crashes, would be a prime source of onomatopoeias. Mimicking these sounds could have allowed early humans to "talk" about the objects; describing goals, methods, and objects. Might handing someone a rock and going "smash" been a way to ask them to make a tool? Perhaps different noises could even refer to different tools. Humans are good at extracting information from mimicked sounds. These sounds also trigger "mirror neurons" - parts of the brain that fire when we observe other people doing something - allowing us to repeat those actions. Seeing someone hold a rock a certain way and saying "smash" could have helped our ancestors teach the proper way to smash. But the biggest benefit would be the fact that you can communicate about these objects without seeing them. Having a sound for a tool would allow you to ask someone for it, even if they didn't have it on them. Given these advantages, it's easy to imagine how evolution would have favoured people who mimicked noises. Over time, this would have driven the development of more and more complex communication; until language as we recognise it emerged. Following this narrative, you can see (or maybe hear) how an a human ancestor with almost no language capability gradual

This study looks at how age of acquisition affects second language learning and how it can influence cognitive processing. Bilingual Spanish and English speakers appear to have an advantage over monolingual individuals, with bilingualism shaping word learning and memory capacity. Specifically, early bilinguals performed better than monolingual individuals and late bilingual learners. There were two mechanisms discussed at the end of the study. The first is based on the critical-period-based phenomenon. The second is based on longer exposure to the two languages, which contributes to bilingual advantages.

The extra information provided in music can facilitate language learning. The researchers of this study also suggest that other information, like gestures, might be equally helpful for learning a language. In addition, there is additional evidence suggesting that music plays an important role in language. Similar areas of the brain are activated when listening to or playing music and speaking or processing language. Language and music are both associated with emotions. And of course, we know that children - especially small children - really like music. This study offers another bit of evidence that the link between language and music may be a fundamental one.

A team of researchers from Rice University and University of Maryland, College Park argue that it is more productive from a developmental perspective to describe spoken language as a special type of music. A review of existing studies presents a compelling case that musical hearing and ability is essential to language acquisition. In addition, we challenge the prevailing view that music cognition matures more slowly than language and is more difficult; instead, the researchers argue that music learning matches the speed and effort of language acquisition, and indeed, that "it is our innate musical intelligence that makes us capable of mastering speech." They conclude that music merits a central place in our understanding of human development.

The researchers of this study advance the idea that spoken language is introduced to the child as a vocal performance, and children attend to its musical features first. Without the ability to hear musically, it would be impossible to learn to speak. In addition, they question the view that music is acquired more slowly than language (Wilson, 2012) and demonstrate that language and music are deeply entangled in early life and develop along parallel tracks. Rather than describing music as a "universal language," they find it more productive from a developmental perspective to describe language as a special type of music in which referential discourse is bootstrapped onto a musical framework. Newborn infants' extensive abilities in different aspects of speech perception have often been cited as evidence that language is innate (e.g., Vouloumanos and Werker, 2007). However, these abilities are dependent on their discrimination of the sounds of language, the most musical aspects of speech. Music has a privileged status that enables us to acquire not only the musical conventions of our native culture, but also enables us to learn our native language. Without the ability to hear musically, we would be unable to learn language.

In this TED-Talk, Dr. Naja Ferjan Ramirez, linguistics professor at the University of Washington and a specialist in the brain processes of children 0-3 years, lays out the benefits of bilingualism, tells how to optimize language learning to achieve better acquisition, and dispels some common concerns about the cons of creating a bilingual child. No surprises here: start early, and create conditions where babies are exposed to the desired target languages-this will enable babies to process the sounds of dual languages, not just one. Ideally, babies will have frequent, social interactions with fully-competent, fluent speakers of the target languages. Ramirez also mentions a major cognitive benefit to bilingualism: a strengthened prefrontal cortex: the area of the brain that deals with task-switching and flexible thinking.

Northwestern University researchers, led by Dr Nina Kraus, found that poor readers had reduced neural response (auditory brainstem activity) to rhythmic rather than random sounds compared to good readers. In fact the level of neural enhancement to acoustic regularities correlated with reading ability as well as musical aptitude. The musical ability test, specifically the rhythm aspect, was also related to reading ability. Similarly a good score on the auditory working memory related to better reading and to the rhythm aspect of musical ability. Dr Kraus explained, "Both musical ability and literacy correlated with enhanced electrical signals within the auditory brainstem. Structural equation modeling of the data revealed that music skill, together with how the nervous system responds to regularities in auditory input and auditory memory/attention accounts for about 40% of the difference in reading ability between children. These results add weight to the argument that music and reading are related via common neural and cognitive mechanisms and suggests a mechanism for the improvements in literacy seen with musical training."

This article talks about why it is impossible to study a sentence and look at the physical structure of the letters without reading or comprehending the sentence meaning. It references the Stroop Effect, which is a cognitive interference where there is a delay in the reaction time of a certain task occurs due to a stimuli conflicting. So when people are told to read a set of words such as "orange, purple, green, blue, yellow", but the color of these words are not that of what they read, people usually stumble as they read. It was interesting because when we are children, it was the opposite, but once we learn the skill to read, it becomes irreversible.

Over the years, we have found that our words come from different parts of the brain. In addition the part of the brain which we use to formulate thoughts into sentences, we also use the part of the brain that deals with emotion when we swear. Researchers discovered that patients with neurodegenerative diseases like a stroke, were still able to swear. Studying patients with Tourette syndrome have also proved that swearing uses many areas of the brain. Since swearing involves the emotional part of the brain, we know that profanity is used to express intense emotions.

Regular speech is generated in the left hemisphere, in an area of the brain close to the surface. The cerebral cortex, or "gray matter," is often associated with higher thought processes such as thought and action. "It's sophisticated," says Bergen, "and comports with the idea of what it means to be human." Swearing, on the other hand, is generated much deeper in the brain, in regions that are older and more primitive in evolutionary terms, says Bergen. These regions are often found in the right hemisphere in the brain's emotional center, the limbic system."These are words that express intense emotions-surprise, frustration, anger, happiness, fear," says psychologist and linguist Timothy Jay, who began studying profanity more than 40 years ago."[Swearing] serves my need to vent, and it conveys my emotions to other people very effectively and symbolically," he says. "Where other animals like to bite and scratch each other, I can say 'f*ck you' and you get my contempt-I don't have to do it physically." Profanity serves other purposes, too. Lovers use it as part of enticing sex talk; athletes and soldiers use it to forge camaraderie; and people in positions of power use it to reaffirm their superiority. Profanity is even used as a celebratory expression, says Adams, citing "F*ck yeah!" as an example. The meaning of a profanity, like any other word, changes with time, culture and context. While swear words have been around since Greek and Roman times, and maybe even earlier, the types of things people consider offensive have changed. "People of the Middle Ages had no problems talking about sex or excrement, that was not their hang-up," Adams explains. "Their hang-up was talking about God disrespectfully...so that was what a profanity was."

The left hemisphere of the brain is responsible for emotions like happiness, sadness, and anger. The part of the brain that we use to formulate thoughts into sentences is that part that we also use to deal with emotion when we swear. Different studies done on people found with brain issues/diseases allowed researchers to understand that profanity is used to express the extreme emotions.
