Researchers from Brown University and King's College London have uncovered new details about how brain anatomy influences language development in young kids. Using advanced MRI, they find that different parts of the brain appear to be important for language development at different ages. Their study, published in the Journal of Neuroscience, found that the explosion of language acquisition that typically occurs in children between 2 and 4 years old is not reflected in substantial changes in brain asymmetry. Structures that support language ability tend to be localized on the left side of the brain. For that reason, the researchers expected to see more myelin -- the fatty material that insulates nerve fibers and helps electrical signals zip around the brain -- developing on the left side in children entering the critical period of language acquisition. Surprisingly, anatomy did not predict language very well between the ages of 2 and 4, when language ability increases quickly. "What we actually saw was that the asymmetry of myelin was there right from the beginning, even in the youngest children in the study, around the age of 1," said the study's lead author, Jonathan O'Muircheartaigh, the Sir Henry Wellcome Postdoctoral Fellow at King's College London. "Rather than increasing, those asymmetries remained pretty constant over time." That finding, the researchers say, underscores the importance of environment during this critical period for language. While asymmetry in myelin remained constant over time, the relationship between specific asymmetries and language ability did change, the study found. To investigate that relationship, the researchers compared the brain scans to a battery of language tests given to each child in the study. The comparison showed that asymmetries in different parts of the brain appear to predict language ability at different ages. "Regions of the brain that weren't important to successful language in toddlers became more important i

Dyslexia is the most common learning disability in the U.S. Scientists are exploring how human brains learn to read, and are discovering new ways that brains with dyslexia can learn to cope. 2 areas on the left side of the brain are key for reading: 1. the left temporoparietal cortex: traditionally used to process spoken language. When learning to read, we start using it to sound out words. 2. the occipitotemporal cortex: part of the visual processing center, located at the base of our brain, behind our ears. A person who never learned to read uses this part of the brain to recognize objects - like a toaster or a chair. But, as we become fluent readers, we train this brain area to recognize letters and words visually. These words are called sight words: any word that you can see and instantly know without thinking about the letters and sounds. This requires retraining the brain. When recognizing a chair, the brain naturally sees it from many different angles - left, right, up, down - and, regardless of the perspective, the brain knows it is a chair. But that doesn't work for letters. Look at a lowercase 'b' from the backside of the page, and it looks like a lowercase 'd.' They are the same basic shape and, yet, two totally different letters. But, as it does with a chair, the brain wants to recognize them as the same object. Everyone - not just people with dyslexia - has to teach the brain not to conflate 'b' and 'd'. The good news: intervention and training can help. At the end of the six week training sessions with dyslexics, the brain areas typically associated with reading, in the left hemisphere, became more active. Additionally, right hemisphere areas started lighting up and helping out with the reading process. The lead scientist, Dr. Eden, says this is similar to what scientists see in stroke victims, where other parts of the brain start compensating.

One significant concern that pilots have about cockpit auditory warnings is that the signals presently used lack a sense of priority. The relationship between auditory warning sound parameters and perceived urgency is, therefore, an important topic of enquiry in aviation psychology. The present investigation examined the relationship among subjective assessments of urgency, reaction time, and brainwave activity with three auditory warning signals. Subjects performed a tracking task involving automated and manual conditions, and were presented with auditory warnings having various levels of perceived and situational urgency. Subjective assessments revealed that subjects were able to rank warnings on an urgency scale, but rankings were altered after warnings were mapped to a situational urgency scale. Reaction times differed between automated and manual tracking task conditions, and physiological data showed attentional differences in response to perceived and situational warning urgency levels. This study shows that the use of physiological measures sensitive to attention and arousal, in conjunction with behavioural and subjective measures, may lead to the design of auditory warnings that produce a sense of urgency in an operator that matches the urgency of the situation.

Maltz and Borker argue that "American men and women come from different sociolinguistic subcultures, having learned to do different things with words in a conversation, so that when they attempt to carry on conversations with one another, even if both parties are attempting to treat one another as equals, cultural miscommunication results." Their article also provides a literature review of various studies examining male-female miscommunication. Here's the synopsis of the differences discovered in female vs. male conversation. Women generally 1. Display a greater tendency to ask questions. 2. Tend to facilitate and elicit interaction more. 3. Make greater use of positive minimal responses, e.g. "mm...I see", and insert them mid-conversation. 4. More likely to adopt a "silent protest" response to interruption 5. Greater tendency to use the pronouns "you" and "we", explicitly acknowledging the presence of the other. In contrast, men are 1. More likely to interrupt 2. More likely to challenge or dispute their partners' utterances 3. more likely to ignore the comments of the other speaker, that is, to offer no response or acknowledgment at all, or respond reluctantly 4. Utilize more mechanisms for controlling the topic of conversation 5. more likely to make direct declarations.

Review of "Through the Language Glass," by Guy Deutscher (who wrote that NYT article). One interesting part: "As he sums it up, "what Gladstone was proposing was nothing less than universal color blindness among the ancient Greeks." He goes on to discuss Lazarus Geiger, who "reconstructed a complete chronological sequence for the emergence of sensitivity to different prismatic colors" and asked the crucial question "Can the difference between [the ancient Greeks] and us be only in the naming, or in the perception itself?" Then there was Hugo Magnus, who decided sensitivity to colors had been evolving since ancient times..."

By Lera Boroditsky (Stanford researcher) "Scholars have long wondered whether different languages might impart different cognitive abilities. In recent years empirical evidence for this causal relation has emerged, indicating that one's mother tongue does indeed mold the way one thinks about many aspects of the world, including space and time. The latest findings also hint that language is part and parcel of many more aspects of thought than scientists had previously realized."

Code-switching involves moving freely between two different languages or dialects of a single language. Many people of color, especially mixed-race and multi-cultural people naturally code-switch. This article shows us Sheena Cobb as an example because she uses both the American Sign Language (ASL) and Black ASL depending on who she is with. Elements of black culture appear in Black ASL such as religious practice, cooking, humor, music, hairstyles, words and phrases typically used in the black communities. People who use Black ASL tend to sign with two hands, in different positions, in a larger signing space and with more repetition than with regular ASL signs.

Love comes in all different shapes, sizes and languages. Helena Halmari, English and Linguistics professor, held a forum on Friday that examined love letters between Finnish composer Jean Sibelius and his wife, Aino. Halmari has been studying the letters through which the couple corresponded. What Halmari has found to be so interesting is that Jean wrote mostly in Swedish, while Aino wrote in Finnish. She talked about the different ways she studied the languages. "I wanted to get a general idea of how the languages were divided," said Halmari. "I knew that it could be very simple because Sibelius uses Swedish and Aino uses Finnish, but it wasn't always simple because they sometimes mixed each other's languages together. Most of the time, though, they stick to their own languages, which didn't make it hard for them at all because they were both bilingual." One would expect the use of two different languages to affect communication in some way, especially negatively. However, Jean and Aino were able to clearly understand each other, and even appreciated the other's use of their first language. Halmarin discussed the relationship between the two. "I don't think their use of two different languages impeded their communication because they both knew each other's languages," said Halmari. "For Jean, Swedish was the preferred written language, because he always worried that he would make mistakes when writing in Finnish." While she has examined forms of bilingual audio communication, such as medieval sermons and recordings, the letters are the first written form of bilingual communication that Halmari has come across. "I haven't looked at letters that were like this before," Halmari said. "In my research, I've looked at bilingual spoken language like recordings, and even email correspondence. They tend to follow the same patterns, though it's not as clear, because some people mix the languages sometimes within the same senten

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

Different genders speak differently, and these differences begin in the gestures that both genders use. Gesture use is very important in language development in both genders.

Dr. Joy Hirsch, head of Memorial Sloan-Kettering Hospital's functional M.R.I. Laboratory, and her graduate student, Karl Kim, found that second languages are stored differently in the human brain, depending on when they are learned. Babies who learn two languages simultaneously, and apparently effortlessly, have a single brain region for generating complex speech, researchers say. But people who learn a second language in adolescence or adulthood possess two such brain regions, one for each language. To explore where languages lie in the brain, Dr. Hirsch recruited 12 healthy bilingual people from New York City. Ten different languages were represented in the group. Half had learned two languages in infancy. The other half began learning a second language around age 11 and had acquired fluency by 19 after living in the country where the language was spoken. With their heads inside the M.R.I. machine, subjects thought silently about what they had done the day before using complex sentences, first in one language, then in the other. The machine detected increases in blood flow, indicating where in the brain this thinking took place. Activity was noted in Wernicke's area, a region devoted to understanding the meaning of words and the subject matter of spoken language, or semantics, as well as Broca's area, a region dedicated to the execution of speech, as well as some deep grammatical aspects of language. None of the 12 bilinguals had two separate Wernicke's areas, Dr. Hirsch said. But there were dramatic differences in Broca's areas, Dr. Hirsch said. In people who had learned both languages in infancy, there was only one uniform Broca's region for both languages, a dot of tissue containing about 30,000 neurons. Among those who had learned a second language in adolescence, however, Broca's area seemed to be divided into two distinct areas. Only one area was activated for each language. These two areas lay close to each other but were always separate, Dr. Hirsch s

Some 50 years ago, the renowned linguist Roman Jakobson pointed out a crucial fact about differences between languages in a pithy maxim: "Languages differ essentially in what they must convey and not in what they may convey." This maxim offers us the key to unlocking the real force of the mother tongue: if different languages influence our minds in different ways, this is not because of what our language allows us to think but rather because of what it habitually obliges us to think about. When your language routinely obliges you to specify certain types of information, it forces you to be attentive to certain details in the world and to certain aspects of experience that speakers of other languages may not be required to think about all the time. And since such habits of speech are cultivated from the earliest age, it is only natural that they can settle into habits of mind that go beyond language itself, affecting your experiences, perceptions, associations, feelings, memories and orientation in the world.

Sex-based differences in the form of English compliments and in the frequencies of various compliment response types are discussed. Based on a corpus of I,062 compliment events, several differences in the form of compliments used by women and men are noted. Further, it is found that compliments from men are generally accepted, especially by female recipients, whereas compliments from women are met with a response type other than acceptance.

Achoo! Atchoum! Hatschi! Etcì! Why does the same body reaction--a sneeze--produce different sounds all over Europe? Different European languages use a different onomatopeia to transcribe into words the simple act of sneezing. And the proper social responses to sneezing in the various countries mean different things and encode varied cultural beliefs about the act.

This post is about Korean language and the two main sections of speech styles in Korea. It will help you better understand the different speaking styles in Korean and when and how to use them. The two styles of speech, 존댓말 (Polite speech) and 반말 (Informal speech), are spoken based on hierarchy since Korean culture has strong Confucian influence due to the country's history. The hierarchy is mainly based on age and social status. For example, when speaking to a teacher in school, you would speak to them with polite speech because they are older than you and know more than you. Phrases and sentences can be said in different ways depending on the style of speech used, but will still have the same meaning.

Researchers have long agreed girls have superior language abilities to boys, but haven't clearly provided a biological basis to account for their differences. For the first time and in unambiguous findings, researchers show both that brain areas associated with language work harder in girls during language tasks, and that boys and girls rely on very different parts of the brain when performing these tasks. Language processing is more abstract in girls, more sensory in boys.

This article distinguishes the difference between connotation and denotation. It explains and shows how difference in the connotations of words can alter the meaning of what you are trying to say. Even if the definitions of the words are the same, their connotations might paint different pictures. With connotation you can shift the meaning of a word to fit your viewpoint/argument.

The difference between the two and how they come about.
