Researchers at the University of Washington and University of Connecticut examined thousands of 30-second snippets of verbal exchanges between parents and babies. They measured parents' use of a regular speaking voice versus an exaggerated, animated baby talk style, and whether speech occurred one-on-one between parent and child or in group settings. "What our analysis shows is that the prevalence of baby talk in one-on-one conversations with children is linked to better language development, both concurrent and future," said Patricia Kuhl, co-author and co-director of UW's Institute for Learning & Brain Sciences. The more parents exaggerated vowels -- for example "How are youuuuu?" -- and raised the pitch of their voices, the more the 1-year olds babbled, which is a forerunner of word production. Baby talk was most effective when a parent spoke with a child individually, without other adults or children around. "The fact that the infant's babbling itself plays a role in future language development shows how important the interchange between parent and child is," Kuhl said.

Employees carrying out an insider attack at work can be identified from the language they use in emails, according to psychologists. The Lancaster University study found that an analysis of the email language of employees within an office environment managed to identify 80 to 90 per cent of those actively stealing confidential information and passing it to a provocateur. Their analysis found that the attackers were much more self-focused, using words like "me," "my" and "I" and they used more negative language compared with typical co-workers. They also found that employees conducting an insider attack reduced the extent to which they mimicked the language of their co-workers. This reduction in mimicry, which suggests an inadvertent social distancing by the attackers, increased over time, such that by the end of simulation, it was possible for the researchers to use the combined metrics to identify 92.6% of insiders.

Some people seem to pick up a second language with relative ease, while others have a much more difficult time. Now, a new study suggests that learning to understand and read a second language may be driven, at least in part, by our ability to pick up on statistical regularities. Some research suggests that learning a second language draws on capacities that are language-specific, while other research suggests that it reflects a more general capacity for learning patterns. According to psychological scientist and lead researcher Ram Frost of Hebrew University, the data from the new study clearly point to the latter: "These new results suggest that learning a second language is determined to a large extent by an individual ability that is not at all linguistic," says Frost. In the study, Frost and colleagues used three different tasks to measure how well American students in an overseas program picked up on the structure of words and sounds in Hebrew. The students were tested once in the first semester and again in the second semester. The students also completed a task that measured their ability to pick up on statistical patterns in visual stimuli. The participants watched a stream of complex shapes that were presented one at a time. Unbeknownst to the participants, the 24 shapes were organized into 8 triplets -- the order of the triplets was randomized, though the shapes within each triplet always appeared in the same sequence. After viewing the stream of shapes, the students were tested to see whether they implicitly picked up the statistical regularities of the shape sequences.

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

A good working memory is perhaps the brain's most important system when it comes to learning a new language. But it appears that working memory is first and foremost determined by our genes. Mila Vulchanova, a professor at NTNU's Department of Modern Foreign Languages, led a study of approximately one hundred ten-year-old elementary school students from Norway. Her research suggests that a good working memory is a decisive factor in developing good language skills and competency. Vulchanova states, "Not only is working memory important in learning new words, it is also important in our general language competence, in areas such as grammar skills. Working memory is connected to our ability to gather information and work with it, and to store and manipulate linguistic inputs as well as other inputs in the brain." Vulchanova's results run contrary to some conventional assumptions in both linguistics and cognitive sciences. Quite often it is believed that children acquire languages regardless of their cognitive abilities, such as perception, spatial understanding, and working memory. In other words, children don't need to learn language per se. It just comes on its own. The results from Vulchanova's research contradict this idea. Not only did the researchers find out that there is a close relationship between language competence in the first language and working memory, but that language competence in the mother tongue correlated highly with skills in a foreign language. "We have found evidence that there is a link between language development and the capacity of our working memory, and that there are common cognitive mechanisms that support the ability to learn both your mother tongue and a second language," Vulchanova says. "This is important, because it has been the tradition in linguistics to maintain that learning your native language is qualitatively different from learning a foreign language," she says.

Research by the University of Liverpool has found that the same brain activity is used for language production and making complex tools, supporting the theory that they evolved at the same time. Dr Georg Meyer, from the University Department of Experimental Psychology, said: "This is the first study of the brain to compare complex stone tool-making directly with language. "Our study found correlated blood-flow patterns in the first 10 seconds of undertaking both tasks. This suggests that both tasks depend on common brain areas and is consistent with theories that tool-use and language co-evolved and share common processing networks in the brain."

A 2013 joint study, conducted by the Montreal Neurological Institute and Hospital -- The Neuro at McGill University and Oxford University, concludes that the pattern of brain development is similar if you learn one or two languages 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. "The later in childhood that the second language is acquired, the greater are the changes in the inferior frontal cortex," said Dr. Denise Klein, researcher in The Neuro's Cognitive Neuroscience Unit and a lead author on the paper published in the journal Brain and Language. "Our results provide structural evidence that age of acquisition is crucial in laying down the structure for language learning."

Researchers at Georgia State University's Language Research Center examined how two language-trained chimpanzees communicated with a human experimenter to find food. Their results are the most compelling evidence to date that primates can use gestures to coordinate actions in pursuit of a specific goal. Dr. Charles Menzel, a senior research scientist, notes, "The chimpanzees used gestures to recruit the assistance of an otherwise uninformed person and to direct the person to hidden objects 10 or more meters away...the findings illustrate the high level of intentionality chimpanzees are capable of, including their use of directional gestures. This study adds to our understanding of how well chimpanzees can remember and communicate about their environment."

Teaching a baby to speak is more art than science. It begins with babble and almost like magic the child says mama and dada, then no, uh-oh, mine, especially mine. But sometimes children struggle to learn to speak. A team of linguists, computer scientists and psychologists in Britain think robots might help explain why that happens. They've created the world's first baby robot, DeeChee; white plastic skin and a smile of red lights and articulated hands that grab and gesture almost like an infant. Now, scientists hope that DeeChee's silicon brain will help explain what's going on in the minds of human babies, specifically, how sensitivity to particular sounds helps infants learn words.

2006 NPR interactive news special on the social underpinnings of language, containing short sound bites with various language researchers. 5 topics are covered: the importance of context in helping deduce meaning, social connections and language, Theory of Mind (how humans observe each other, gauging the effect that words are having on listeners, in order to assess others' beliefs, intentions and desires), and empathy. The video clip of Kanzi, the bonobo ape, cooking hamburgers with his human friends is a classic!

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

Prior to the late 1880s, Chickasaw was the dominant language in Chickasaw Nation, in the southern part of central Oklahoma, yet today, only 65 fluent speakers, all bilingual in Chickasaw and English, remain. The death of Emily Johnson Dickerson, the last monolingual Chickasaw speaker, in December 2013 has spurred reflection on the erosion and future of this endangered language.

As e-readers grow in popularity as convenient alternatives to traditional books, researchers have found that convenience may not be their only benefit. The team discovered that when e-readers are set up to display only a few words per line, some people with dyslexia can read more easily, quickly and with greater comprehension.

In this essay, D.E. Whittkower, in the Dept. of Philosophy at Old Dominion University, attempts to establish that social media communications constitute a secondary literacy, which shares many of the features of spoken language ("orality"). Whittkower's discussion of Facebook, in particular, is thought-provoking; he suggests that the site is a "remarkably well-suited site for the activity of friendship," providing opportunities for relationships and interests to grow and intensify and for participants to engage in linguistic and post-linguistic social grooming.
