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

Can babies learn to read? While parents use DVDs and other media in an attempt to teach their infants to read, these tools don't instill reading skills in babies, a study by researchers at New York University's Steinhardt School of Culture, Education, and Human Development has found. In their study, which appears in the Journal of Educational Psychology, the researchers examined 117 infants, aged nine to 18 months, who were randomly assigned to treatment and control groups. Children in the treatment condition received a baby media product, which included DVDs, word and picture flashcards, and flip books to be used daily over a seven-month period; children in the control condition did not receive these materials from the researchers. Over the course of seven months, the researchers conducted a home visit, four laboratory visits, and monthly assessments of language Development. To test children's emerging skills in the laboratory, the researchers examined the capacity to recognize letter names, letter sounds, vocabulary, words identified on sight, and comprehension. A combination of eye-tracking tasks and standardized measures were used to study outcomes at each stage of Development. Using a state-of-the art eye-tracking technology, which follows even the slightest eye movements, the researchers were able to closely monitor how the infants distributed their attention and how they shifted their gaze from one location to another when shown specific words and phrases. No discernible differences were observed between the results of the experimental group vs. the control; yet parents of the infants in the experimental group perceived that their children were, in fact, acquiring words. :-)

This article discusses the importance of baby babble in language development.

Researchers have found they can go far in predicting which children with autism will eventually develop language and which will not - based on differences in brain activity when the children are infants and toddlers. The findings represent a potential breakthrough in tailoring future early intervention programs to improve communication and language even before a diagnosis of autism is possible at 18 to 24 months.

How TV shows, more specifically Peppa Pig, affect language development in young children. This study looked at the language lexicons within episodes and evaluated whether or not it was appropriate for young language learners.

Lera Boroditsky, cognitive science professor at UC San Diego notes, "...a growing body of research is documenting how experience with language radically restructures the brain. People who were deprived of access to language as children (e.g., deaf individuals without access to speakers of sign languages) show patterns of neural connectivity that are radically different from those with early language exposure and are cognitively different from peers who had early language access. The later in life that first exposure to language occurs, the more pronounced and cemented the consequences. Further, speakers of different languages develop different cognitive skills and predispositions, as shaped by the structures and patterns of their languages. Experience with languages in different modalities (e.g., spoken versus signed) also develops predictable differences in cognitive abilities outside the boundaries of language. For example, speakers of sign languages develop different visuospatial attention skills than those who only use spoken language. Exposure to written language also restructures the brain, even when acquired late in life. Even seemingly surface properties, such as writing direction (left-to-right or right-to-left), have profound consequences for how people attend to, imagine, and organize information. The normal human brain that is the subject of study in neuroscience is a "languaged" brain. It has come to be the way it is through a personal history of language use within an individual's lifetime. It also actively and dynamically uses linguistic resources (the categories, constructions, and distinctions available in language) as it processes incoming information from across the senses.

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

Although the expectation of how the English language develops in other countries may seem positive, the reality isn't the same. For example, students are being taught Krio, a dialect similar to English, but not English. This makes it unfair for those students when they get older because they were never taught the right English. Because of the difference between expectation and reality, specialists have been searching for ways to balance them out.

When a human baby is born, its first cry is a normal sign of good health. Having never taken a breath before, the baby signals its first inhalation and exhalation-in the form of a screech. How do babies know to create a sound they've never made before? And is their first yelp truly the start of speech development? As it turns out, human babies may be practicing how to cry long before they ever make a sound. That is, if they're anything like marmosets, humans' primate cousins. A study of marmosets by Daniel Takahashi, a co-author of the study and an animal behaviorist at the Brain Institute at the Federal University of Rio Grande do Norte in Brazil. shows fetal monkeys practicing crying in the womb. Takahashi notes, "marmosets are monkeys that we know vocalize a lot, and they share a lot of features with humans." For instance, both male and female parents raise their offspring together, and unlike other primates, marmoset babies are relatively helpless when they're born, like human infants. Takahashi says the central finding will help illuminate when speech development begins, and that studying pre-birth-rather than the moment of birth-may help identify speech or motor development problems earlier. "There are a lot of things going on in the womb that might be relevant to what's going on afterwards," he says.

This article talks about the importance of speaking development of babies from ages 0 to 12 months old. It helps parents (and others) understand how a baby tries to communicate their feelings with the noises they make. It is useful to know the way babies try to speak to us in order to understand if they are hungry, tired, happy, etc. and be able to respond to their needs.

An article explaining how language develops as a baby.

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.

Although it has a genetic component, most believe perfect pitch - or absolute pitch - is a primarily a function of early life exposure and training in music, says Takao Hensch, professor of molecular and cellular biology at Harvard. Hensch is studying valprioc acid, a drug which might allow adults to learn perfect pitch by re-creating this critical period in brain development. "It's a mood-stabilizing drug, but we found that it also restores the plasticity of the brain to a juvenile state," Hensch says. Valprioc acid allows the brain to absorb new information as easily as it did before age 7. Hensch's findings have potentially valuable implications for other critical-period-related developments, language being one. So the sci-fi question: in the future, can we come up with a way to reopen plasticity, [and] paired with the appropriate training, allow adult brains to become young again?

Cognitive neuroscientists warn that humans may be developing digital brains with new circuits for skimming through the torrent of information online. This alternative way of reading is competing with traditional deep reading circuitry developed over several millennia.

Childhood language acquisition can be affected by the development of cognitive capabilities and interactions.

(Jump to point 3). Children learn language through hearing, so making sure they have lots of things to listen to is critical. Toddlers whose mothers talked with them have bigger vocabularies.

An interesting story--my students, you might recall Sheryl Turkle of MIT referencing robot therapists in her TED talk. USC has developed a robot therapist, Ellie, designed to talk to people who are struggling emotionally, and to take their measure in a way no human can. Originally developed to work with military PTSD patients, Ellie's purpose: to gather information and provide real human therapists detailed analysis of patients' movements and vocal features, in order to give new insights into people struggling with emotional issues. The body, face and voice express things that words sometimes obscure. Ellie's makers believe that her ability to do this will ultimately revolutionize American mental health care.

Developing language skills appears to be more important for boys than girls in helping them to develop self-control and, ultimately, succeed in school, according to a study led by a Michigan State University researcher. Language skills -- specifically the building of vocabulary -- help children regulate their emotions and behavior and that boys lag behind girls in both language skills and self-regulation. The researchers noted that while girls overall seemed to have a more natural ability to control themselves and focus, boys with a strong vocabulary showed a dramatic increase in this ability to self-regulate -- even doing as well in this regard as girls with a strong vocabulary.

Research about the association between music and speech. Tonal languages, such as Mandarin, support theories of language developing out of a "protolanguage" comprised of sounds that were more similar to tones than words.
