Gestural Communication Paper - De Waal « Language Evolution - 0 views

  • “Gestures are used across a wide range of contexts whereas most facial expressions and vocalizations are very narrowly used for one particular context,”
  • Although all primates use their voices and facial expressions to communicate, only people and the great apes — chimpanzees, bonobos, orangutan and gorillas — use these types of gestures as well. De Waal noted that great apes first appeared about 15 to 20 million years old, meaning such gestures may have been around that long. “A gesture that occurs in bonobos and chimpanzees as well as humans likely was present in the last common ancestor,” Pollick said in a statement. “A good example of a shared gesture is the open-hand begging gesture, used by both apes and humans.” This last common ancestor may date to about 5 million to 6 million years ago.
  • He added that when the apes gesture, they like to use their right hands, which is controlled by the left side of the brain — the same side where the language control center appears in the human brain.

Do E-Books Make It Harder to Recall What You Just Read? | TIME.com - 4 views

  •  
    "...when the exact same material is presented in both media, there is no measurable difference in student performance. ... However, there are some subtle distinctions that favor print, which may matter in the long run. ... First, more repetition was required with computer reading to impart the same information. "Second, the book readers seemed to digest the material more fully. ... seemingly irrelevant factors like remembering whether you read something at the top or the bottom of page - or whether it was on the right or left hand side of a two-page spread or near a graphic - can help cement material in mind. ... spatial context may be particularly important because evolution may have shaped the mind to easily recall location cues so we can find our way around ... E-books, however, provide fewer spatial landmarks than print."

Is a Threat Posted on Facebook Really a Threat? - 0 views

  •  
    The U.S. Supreme Court is tackling a question of increasing importance in the age of social media and the Internet: What constitutes a threat on Facebook? Anthony Elonis was convicted of threatening both his estranged wife and an FBI agent. After his wife left him, taking the couple's two children with her, Elonis began posting about her on his Facebook page. Elonis was indicted on five counts of interstate communication of illegal threats. At his trial, he acknowledged the violence voiced in his posts, but argued he was exercising his First Amendment free speech rights. Longtime federal prosecutor, Patrick Fitzgerald, however, notes that most of the posts occurred after Elonis' wife had gotten a protective court order, and that Elonis posted his messages on his Facebook page without restriction. Thus, Fitzgerald contends that the husband reasonably foresaw what the reaction would be. "The wife would read this and think, this is not an artistic statement, this is not a political statement about a larger cause," says Fitzgerald. "This is trying to get inside her head and make her think there could be someone doing violence to her."

Broca's and Wernicke's Areas: Human Uniqueness Compared to "Great Apes": Relative Diff... - 0 views

  •  
    Other, non-human primates have Broca's and Wernicke's areas in their brains, as do humans. In both species, the Broca's region represents non-linguistic hand and mouth movements. Evidence also suggests that both species may have mirror neurons in this region that are involved in understanding the actions and intentions of others. In both macaques and humans, this region is likely involved in producing orofacial expressions and in understanding the intentions behind orofacial expressions of others. In humans, it has evolved an additional communicative function, namely speech production. Interestingly however, it does not appear to be involved in monkey vocalizations, which are instead mediated by limbic and brainstem areas.

Saving the World's Dying and Disappearing Languages - 0 views

  •  
    Between 1950 and 2010, 230 languages went extinct, according to the UNESCO Atlas of the World's Languages in Danger. Today, a third of the world's languages have fewer than 1,000 speakers left. Every two weeks a language dies with its last speaker, 50 to 90 percent of them are predicted to disappear by the next century. Wikitongues wants to save these endangered languages from extinction. Bogre Udell, who speaks four languages, met Frederico Andrade, who speaks five, at the Parsons New School in New York City. In 2014, they launched Wikitongues, an ambitious project to make the first public archive of every language in the world. They've already documented more than 350 languages, which they are tracking online, and plan to hit 1,000 in the coming years. "When humanity loses a language, we also lose the potential for greater diversity in art, music, literature, and oral traditions," says Bogre Udell.

Alternative Influence: Broadcasting the Alternative Right on YouTube - 1 views

  •  
    This report studies 65 political influencers belonging to the Alternative Influence Network (AIN): an assortment of scholars, media pundits, and internet celebrities who use YouTube to promote a range of political positions, from mainstream versions of libertarianism and conservatism, all the way to overt white nationalism. AIN's savvy use of YouTube promotes radicalization and adoption of extremist political viewpoints. Content creators in the AIN claim to provide an alternative media source for news and political commentary. They function as political influencers who adopt the techniques of brand influencers to build audiences and "sell" them on far-right ideology. This report presents data from approximately 65 political influencers across 81 channels. These groups uphold a broader "reactionary" position: a general opposition to feminism, social justice, or left-wing politics. Members of the AIN cast themselves as an alternative media system by: * Establishing an alternative sense of credibility based on relatability, authenticity, and accountability. * Cultivating an alternative social identity using the image of a social underdog, and countercultural appeal. Members of the AIN use the proven engagement techniques of brand influencers to spread ideological content: * Ideological Testimonials * Political Self-Branding * Search Engine Optimization * Strategic Controversy

Does the Language I Speak Influence the Way I Think? - Linguistic Society of America - 0 views

  •  
    What we have learned is that the answer to this question is complicated. To some extent, it's a chicken-and-egg question: Are you unable to think about things you don't have words for, or do you lack words for them because you don't think about them? Part of the problem is that there is more involved than just language and thought; there is also culture. Your culture-the traditions, lifestyle, habits, and so on that you pick up from the people you live and interact with-shapes the way you think, and also shapes the way you talk.

    Have you ever had trouble describing one of your experiences? This article explores how language can restrict us. For example, color is fluid, but language isn't; at one point the color is going to change from red to orange when yellow is slowly added to it. Moreover, the environment in which we live has an influence on the words we use and the ones even in our language. Guugu Yimithirr doesn't have words for the English equivalent of "left", "right", "up", or "down". Instead, directional words (North, South, East, and West) are used. Languages have a great way of affecting how we think and offering new insights.

Language Revival: Learning Okinawan helps preserve culture and identity - 3 views

  •  
    Article talks about an adult Okinawan-language class in Hawaii. Okinawan, also known as Uchinaaguchi, is an endangered language--it fell into disuse due to Japanese colonization--hence few native speakers of the language remain. I've posted the text of the article below, as you've got to be a Star-Advertiser subscriber to see the full page: POSTED: 01:30 a.m. HST, Aug 27, 2013 StarAdvertiser.com Learning Okinawan helps preserve culture and identity, an instructor says By Steven Mark In a classroom for preschoolers, a group of adults is trying to revive a language that is foreign to their ear but not to their heart. The language is Okinawan, or "Uchinaaguchi," as it is pronounced in the language itself. The class at Jikoen Hongwanji Mission in Kalihi, as informal as it is, might just be the beginning of a cultural revival thousands of miles to the east of the source. At least that is the hope of Eric Wada, one of the course instructors. "For us, it's the importance of connecting (language) to identity," said Wada, who studied performing arts in Okinawa and is now the artistic director of an Okinawan performing arts group, Ukwanshin Kabudan. "Without the language, you really don't have identity as a people." Okinawa is the name given to a prefecture of Japan, but it was originally the name of the main island of an archipelago known as the Ryukyu Islands that lies about midway between Japan and Taiwan in the East China Sea. For centuries, the Ryukyu kingdom maintained a degree of independence from other East Asian nations. As a result, distinctive cultural practices evolved, from graceful and meditative dance to the martial art called karate and the poetic language that sounds like a blend of Japanese and Korean. The islands were officially annexed by Japan in 1879. The 20th century saw the World War II battle of Okinawa, which claimed more than a quarter of the island's population, the subsequent placement of U.S. military bases and the return of the islands to

Mapping language in the brain - 1 views

    '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.

Ability to learn new words based on efficient communication between brain areas that co... - 1 views

  •  
    Researchers from King's College London Institute of Psychiatry, in collaboration with Bellvitge Biomedical Research Institute (IDIBELL) and the University of Barcelona, mapped the neural pathways involved in word learning among humans. They found that the arcuate fasciculus, a collection of nerve fibres connecting auditory regions at the temporal lobe with the motor area located at the frontal lobe in the left hemisphere of the brain, allows the 'sound' of a word to be connected to the regions responsible for its articulation. Differences in the development of these auditory-motor connections may explain differences in people's ability to learn words. Researchers used diffusion tensor imaging to image the structure of the brain before a word learning task and functional MRI, to detect the regions in the brain that were most active during the task. They found a strong relationship between the ability to remember words and the structure of arcuate fasciculus, which connects two brain areas: the territory of Wernicke, related to auditory language decoding, and Broca's area, which coordinates the movements associated with speech and the language processing. In participants able to learn words more successfully their arcuate fasciculus was more myelinated i.e. the nervous tissue facilitated faster conduction of the electrical signal. In addition the activity between the two regions was more co-ordinated in these participants. Dr Catani concludes, "Now we understand that this is how we learn new words, our concern is that children will have less vocabulary as much of their interaction is via screen, text and email rather than using their external prosthetic memory. This research reinforces the need for us to maintain the oral tradition of talking to our children."

Why North Carolina Is the Most Linguistically Diverse U.S. State - 1 views

  •  
    The South has various species of both accents and dialects. An accent is composed purely of pronunciation changes, almost always vowel sounds. Dialects, on the other hand, incorporate all kinds of other stuff, including vocabulary, structure, syntax, idioms, and tenses. There were many distinct regional accents or dialects in the pre-Civil War South. North Carolina, smack in the middle of the Atlantic South, found more of those dialects within its borders than any other state. On top of that, North Carolina is home to a dialect found nowhere else in the world: the English spoken by those in the Pamlico Sound region, the coastal area that includes the Outer Banks. Interesting trivia tidbit: Distinctly Southern dialects among the white population of the American South seem only to have taken hold starting around the time of the Civil War.The period from the end of the Civil War until World War I-which seems like a long time, but is very condensed linguistically, less than three generations-saw an explosion of diversity in what are sometimes referred to as Older Southern American Accents. The article also notes the reasons for the South's linguistic diversity in re: accents and dialects, and why those accents and dialects have been perpetuated. In Southern states bordering the Atlantic Ocean, regional dialects sprung up seemingly overnight, influenced by a combination of factors, including the destruction of infrastructure, the panic of Reconstruction, lesser-known stuff like the boll weevil crisis, and the general fact that regional accents tend to be strongest among the poorest people. In the post-Civil War period, Southerners left the South en masse; the ones who stayed were often the ones who couldn't afford to leave, and often the keepers of the strongest regional accents. A lack of migration into the South, either from the North or internationally, allowed its regional accents to bloom in relative isolation. However, after WWII, an influx of Northerne

How Does Our Language Shape the Way We Think? - 2 views

  •  
    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.

The Bilingual Brain - 8 views

  •  
    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.

Scans Show 'Brain Dictionary' Groups Words By Meaning - 2 views

  •  
    Scientists say they have made an atlas of where words' meanings are located in the brain. The map shows that words are represented in different regions throughout the brain's outer layer. Moreover, the brains of different people map language in the same way: words with related meanings lit up similar parts of the brain. Words meanings could pop up in different places simultaneously. Hearing the word "top" caused regions associated with clothing and appearances to light up. But "top" could also stimulate a region associated with words related to numbers and measurements. UC Berkeley neuroscientist, Jack Gallant, who authored the study, says the findings contradict two beliefs nonscientists commonly have about the brain. First, that only the left hemisphere handles language. Second, that the brain has localized regions which handle specific tasks. Contrary to those ideas, he says, language and meaning are distributed. "It's not that there's one brain area and one function," he says. But for Gallant, the real surprise is that the meanings of words triggered the same brain regions across multiple people in his study.

Learning a new language alters brain development - 3 views

  •  
    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.
