"School-age children whose mothers nurtured them early in life have brains with a larger hippocampus ... For the current study, the researchers conducted brain scans on 92 of the children who had had symptoms of depression or were mentally healthy when they were studied as preschoolers. The imaging revealed that children without depression who had been nurtured had a hippocampus almost 10 percent larger than children whose mothers were not as nurturing. ... Although 95 percent of the parents whose nurturing skills were evaluated during the earlier study were biological mothers, the researchers say that the effects of nurturing on the brain are likely to be the same for any primary caregiver - whether they are fathers, grandparents or adoptive parents."

This article discusses the different theories on what influences language development: Nature or Nurture? Is language bound to develop from genetics, or is language dependent on environment?

Author Clive Thompson argues, "The fact that so many of us are writing - sharing our ideas, good and bad, for the world to see - has changed the way we think. Just as we now live in public, so do we think in public. And that is accelerating the creation of new ideas and the advancement of global knowledge." Every day, we collectively produce millions of books' worth of writing. Globally we send 154.6 billion emails, more than 400 million tweets, and over 1 million blog posts and around 2 million blog comments on WordPress. On Facebook, we post about 16 billion words. Altogether, we compose some 3.6 trillion words every day on email and social media - the equivalent of 36 million books.* (The entire US Library of Congress, by comparison, holds around 23 million books.) He notes the Internet has spawned a global culture of avid writers, one almost always writing for an audience, and suggests that writing for a real audience helps clarify one's thinking, enhances learning, and arguably, betters writers' organization, ideas, and attention to editing.

For decades, psychologists cautioned against raising children bilingual. They warned parents and teachers that learning a second language as a child was bad for brain development. But recent studies have found exactly the opposite. Researchers now believe that when people learn another language, they develop cognitive advantages that improve their attention, self-control and ability to deal with conflicting information.

Raising bilingual children is actually good for them. They develop a better ability to concentrate and deal with conflicting information. This could indicate that nurturing a child's brain can increase their language capabilities.

The gene that affects how babies pick up language has been identified. If we know more about this gene, can we nurture children and help them learn to better suit their needs and increase their language capabilities?

Researchers found that people tend to rate discoveries that came about "like a light bulb" as more exceptional than those that are "nurtured like seeds." These two metaphors are often used to describe scientific discovery and what we perceive as genius. Along with them come ingrained, subconscious associations that may have unintended consequences, according to a study published Friday in Social Psychological and Personality Science. Also, those metaphors had different effects depending on the gender of the idea's creator.

Playing a series of sounds to infants can speed up the way they process language and can also predict which infants will have trouble with language as they develop. Researchers concluded that processing language sounds sets up the neural foundation in babies.

The way that babies react to certain sounds can indicate their learning patterns and language capabilities later in life.

What our speech reveals about us

Language is common to all humans; we seem to be "hard-wired" for it. Many social scientists and philosophers say it's this ability to use language symbolically that makes us "human." Though it may be a universal human attribute, language is hardly simple. For decades, linguists' main task was to track and record languages. But, like so many areas of science, the field of linguistics has evolved dramatically over the past 50 years or so. Today's science of linguistics explores: -the sounds of speech and how different sounds function in a language -the psychological processes involved in the use of language -how children acquire language capabilities -social and cultural factors in language use, variation and change -the acoustics of speech and the physiological and psychological aspects involved in producing and understanding it -the biological basis of language in the brain This special report, compiled by the National Science Foundation, touches on nearly all of these areas by answering questions such as: How does language develop and change? Can the language apparatus be "seen" in the brain? Does it matter if a language disappears? What exactly is a dialect? How can sign language help us to understand languages in general? Answers to these and other questions have implications for neuroscience, psychology, sociology, biology and more.

This paper discusses how the gene FOXP2 is related to certain speech and language disorders, such as apraxia, or difficulty coordinating parts of the mouth to form speech. This research is important when placed into the wider debate of Nature Vs. Nurture, as it demonstrates that genetics may have the capacity to influence language acquisition.
