How similar are the gestures of apes and human infants? More than you might suspect - 2 views

  •  
    Psychologists who analyzed video footage of a female chimpanzee, a female bonobo and a female human infant in a study to compare different types of gestures at comparable stages of communicative development found remarkable similarities among the three species. Gestures made by all three species included reaching, pointing with fingers or the head, and raising the arms to ask to be picked up. The researchers called "striking" the finding that the gestures of all three species were "predominantly communicative," Greenfield said. To be classified as communicative, a gesture had to include eye contact with the conversational partner, be accompanied by vocalization (non-speech sounds) or include a visible behavioral effort to elicit a response. The same standard was used for all three species. For all three, gestures were usually accompanied by one or more behavioral signs of an intention to communicate. At the beginning stage of communication development, gesture was the primary mode of communication for human infant, baby chimpanzee and baby bonobo. The child progressed much more rapidly in the development of symbols. Words began to dominate her communication in the second half of the study, while the two apes continued to rely predominantly on gesture. "This was the first indication of a distinctive human pathway to language," Greenfield said. All three species increased their use of symbols, as opposed to gestures, as they grew older, but this change was far more pronounced for the human child. The child's transition from gesture to symbol could be a developmental model of the evolutionary pathway to human language and thus evidence for the "gestural origins of human language," Greenfield said. While gesture may be the first step in language evolution, the psychologists also found evidence that the evolutionary pathway from gesture to human language included the "co-evolution of gestural and vocal communication." Most of the child's gestures were accompanied b

Steven Pinker: Linguistics as a Window to Understanding the Brain - YouTube - 2 views

shared by Dane Kawano on 04 Nov 12 - No Cached
  •  
    Copied from Youtube description: "How did humans acquire language? In this lecture, best-selling author Steven Pinker introduces you to linguistics, the evolution of spoken language, and the debate over the existence of an innate universal grammar. He also explores why language is such a fundamental part of social relationships, human biology, and human evolution. Finally, Pinker touches on the wide variety of applications for linguistics, from improving how we teach reading and writing to how we interpret law, politics, and literature."

Language and Genetics - 0 views

  •  
    Recent advances in our understanding of the genetic basis of human cognition (thinking) have enabled scientists at the Max Planck Institutes for Psycholinguistics, Evolutionary Anthropology, and Human Cognitive and Brain Sciences. to better understand 3 areas of language: 1. Language processing: The human genome directs the organization of the human brain and some peripheral organs that are prerequisites for the language system, and is probably responsible for the significant differences in language skills between individuals. At the extremes are people with extraordinary gifts for learning many languages and undertaking simultaneous interpretation, and people with severe congenital speech disorders. 2. Language and populations: Genetic methods have revolutionized research into many aspects of languages, including the tracing of their origins. 3. Structural differences: While languages are not inborn, certain genetic predispositions in a genetically similar population may favour the emergence of languages with particular structural characteristics - an example thereof is the distinction between languages that are tonal (such as Chinese) and non-tonal (such as German).

Onomatopoeia: The origin of language? - Filthy Monkey Men - 2 views

  •  
    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

Imagine A Flying Pig: How Words Take Shape In The Brain : NPR - 3 views

  •  
    Just a few decades ago, many linguists thought the human brain had evolved a special module for language . It seemed plausible that our brains have some unique structure or system. After all, no animal can use language the way people can. However, in the 1990s, scientists began testing the language-module theory using "functional" MRI technology that let them watch the brain respond to words. And what they saw didn't look like a module, says Benjamin Bergen, a researcher at the University of California, San Diego, and author of the book _Louder Than Words_. "They found something totally surprising," Bergen says. "It's not just certain specific little regions in the brain, regions dedicated to language, that were lighting up. It was kind of a whole-brain type of process." The brain appears to be taking words, which are just arbitrary symbols, and translating them into things we can see or hear or do; language processing, rather than being a singular module, is "a highly distributed system" encompassing many areas of the brain. Our sensory experiences can also be applied to imagining novel concepts like "flying pigs". Our sensory capacities, ancestral features shared with our primate relatives, have been co-opted for more recent purposes, namely words and language. Bergen comments, "What evolution has done is to build a new machine, a capacity for language, something that nothing else in the known universe can do," he says. "And it's done so using the spare parts that it had lying around in the old primate brain."

New Language Points To Foundations Of Human Grammar - 0 views

  •  
    How is a language born? What are its essential elements? Linguists are gaining new insights into these age-old conundrums from a language created in a small village in Israel's Negev Desert. The Al-Sayyid Bedouin Sign Language (ABSL), which serves as an alternative language of a community of about 3,500 deaf and hearing people, has developed a distinct grammatical structure early in its evolution, researchers report, and the structure favors a particular word order: verbs after objects. The study - the first linguistic analysis of a language arising naturally with no outside influence - was published online in the Proceedings of the National Academy of Sciences the week of Jan. 31 to Feb. 4, 2005.

Language & Culture in Society - 0 views

  •  
    From this source it shows a lot about language and its evolution. Although there are psycholinguistic characteristics that all humans share, language learning and teaching is always embedded in cultural and social structures. Languages die out, their uses in a speech community shift over time, and new languages emerge. An individual may lose or gain fluency in a language, or several languages, over their lifetime.

Without Miracles: The Development and Functioning of Thought - 0 views

  • it might come as somewhat of a surprise to learn that some scholars reject natural selection as an explanation for the appearance, structure, and use of language.
  • to use Darwin's term, the roll film of the still camera was preadapted, although quite accidentally and unintentionally, for use in the motion picture camera. To use Gould's more neutral and more accurate terminology, this feature of the still camera was exapted for use in motion picture cameras. So, in effect, Chomsky and Gould assert that the human brain is analogous to roll film in that it evolved for reasons originally unrelated to language concerns; but once it reached a certain level of size and complexity, language was possible.
  • All mammals produce oral sounds by passing air from the lungs through the vocal cords, which are housed in the larynx (or "Adam's apple"). The risk of choking to which we are exposed results from our larynx being located quite low in the throat. This low position permits us to use the large cavity above the larynx formed by the throat and mouth (supralaryngal tract) as a sound filter. By varying the position of the tongue and lips, we can vary the frequencies that are filtered and thus produce different vowel sounds such as the [i] of seat, the [u] of stupid, and the [a] of mama.[9] We thus see an interesting trade-off in the evolution of the throat and mouth, with safety and efficiency in eating and breathing sacrificed to a significant extent for the sake of speaking. This suggests that the evolution of language must have provided advantages for survival and reproduction that more than offset these other disadvantages.

Niche Construction - 1 views

  • An important insight from NCT is that acquired characters play an evolutionary role, through transforming selective environments. This is particularly relevant to human evolution, where our species appears to have engaged in extensive environmental modification through cultural practices. Such cultural practices are typicaly not themselves biological adaptations (rather, they are the adaptive product of those much more general adaptations, such as the ability to learn, particularily from others, to teach, to use language, and so forth, that underlie human culture) and hence, cannot acurately be described as extended phenotypes (1). Mathematical models reveal that niche construction due to human cultural processes can be even more potent than gene-based niche construction, and establish that cultural niche construction can modify selection on human genes and drive evolutionary events (2-4). There is now little doubt that human cultural niche construction has co-directed human evolution in this manner (5)

Noam Chomsky's Theories on Language - Video & Lesson Transcript | Study.com - 0 views

  •  
    Few would argue the significance of language in the evolution of the human species. Language serves many critical functions within the human experience, from keeping us safe to social engagement. While communication certainly exists in other species, the depth and complexity of the human language is second to none.

What one snarky facial expression could teach us about the evolution of language - 1 views

  •  
    This article talks about a face all humans make, the "not face." It combines the 3 emotions of anger, disgust, and contempt. It not only shows that we are able to express complex emotions, but also how the "not face" is closely tied to language. In ASL speakers, the sign for "not" is also replaced with the negative expression. This article also highlights how facial expression affects language and that there could be more facial expressions like grammatical markers.

Language is learned in brain circuits that predate humans -- ScienceDaily - 0 views

  •  
    This source explains how language learning is involved in very basic learning systems that lots of animals have. Language learning falls into either declarative memory (memorize it once) or procedural memory (repeat it over and over until you get it). The research shows that you learn language in one of these two ways. The way that you end up learning in depends on when and how you learn the language.

When was talking invented? A language scientist explains how this unique feature of hum... - 0 views

  •  
    This article caught my attention because it's related to things we have discussed in class. The two main theories of where talking came from that are discussed in this article are exactly what we talked about in class. One thing I found interesting was that "researchers don't really think language was invented; instead [they] think it evolved during human beings' evolution from other apes."

'Language Gene' May Influence Learning Too - 1 views

  •  
    The FOXP2 gene, a front-runner to explain the evolution of language in humans, may have rewired the brain to allow more advanced learning, according to preliminary research presented at the Society for Neuroscience annual meeting this month. In a recent experiment, Christiane Schreiweis of the Max Planck Institute and colleagues looked at the human version of the gene in mice.

With Dogs, It's What You Say - and How You Say It - 1 views

  •  
    This article explores how dogs perceive human language and whether tone of voice matters. Through this experiment, it was discovered that dogs respond positively to a positive tone of voice and neutrally to a neutral tone of voice. However, if the dog was reprimanded in a positive tone of voice, the dog would perceive that as a praise. In terms of language evolution, it suggests that the ability to "process meaning and emotion in different parts of the brain and tie them together is not uniquely human."

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.
