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).

This article talks about how one's genetics and one's language could possibly be connected. This study took place in Cape Verde, where people speak Kriolu, a mixture of European and African languages that formed with the trans Atlantic slave trade. Researchers recorded multiple individual's speech and compared the recordings to the individual's DNA. They found that there was a significant correlation between one's ancestry and the words they use - for example, those with more African genetic ancestry used more African derived words. While this doesn't necessarily conclude that linguistic traits are passed on like genetic traits are, it is interesting that in a language that is a mix of other languages, individuals still use more words that are derived from their ethnic backgrounds.

Language in humans has evolved culturally rather than genetically, according to a new study. By modeling the ways in which genes for language might have evolved alongside language itself, the study showed that genetic adaptation to language would be highly unlikely, as cultural conventions change much more rapidly than genes. Thus, the biological machinery upon which human language is built appears to predate the emergence of language. Professor Nick Chater, University College London Cognitive, Perceptual and Brain Sciences, says: "...although we have appear to have a genetic predisposition towards language, human language has evolved far more quickly than our genes could keep up with, suggesting that language is shaped and driven by culture rather than biology. The linguistic environment is continually changing; indeed, linguistic change is vastly more rapid than genetic change. "

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.

When your brain encounters sensory stimuli, such as the scent of your morning coffee or the sound of a honking car, that input gets shuttled to the appropriate brain region for analysis. The coffee aroma goes to the olfactory cortex, while sounds are processed in the auditory cortex. That division of labor suggests that the brain's structure follows a predetermined, genetic blueprint. However, evidence is mounting that brain regions can take over functions they were not genetically destined to perform. In a landmark 1996 study of people blinded early in life, neuroscientists showed that the visual cortex could participate in a nonvisual function - reading Braille. Now, a study from MIT neuroscientists shows that in individuals born blind, parts of the visual cortex are recruited for language processing. The finding suggests that the visual cortex can dramatically change its function - from visual processing to language - and it also appears to overturn the idea that language processing can only occur in highly specialized brain regions that are genetically programmed for language tasks. "Your brain is not a prepackaged kind of thing. It doesn't develop along a fixed trajectory, rather, it's a self-building toolkit. The building process is profoundly influenced by the experiences you have during your development," says Marina Bedny, an MIT postdoctoral associate in the Department of Brain and Cognitive Sciences and lead author of the study, which appears in the Proceedings of the National Academy of Sciences the week of Feb. 28.

Not about linguistics, but of general interest to students. Talks about genetic basis for test anxiety--and under which conditions it is advantageous. This article is long but gets more interesting the further you read.

Scientists have implemented the human gene deemed responsible for our ability to communicate into a strain of mice. This could be the first step towards having talking animals someday, and it also allows us to understand more about how genetics affect language.

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?

How do babies develop differently, and how does it relate to the brain? How do genetics, environment, etc. play a role?

A new prospective study of six-month-old infants at high genetic risk for autism identified weak head and neck control as a red flag for autism spectrum disorder (ASD) and language and/or social developmental delays.

The importance of FOXP2, and how it affects language.

People have a deep desire to communicate with animals, as is evident from the way they converse with their dogs, enjoy myths about talking animals or devote lifetimes to teaching chimpanzees how to speak. A delicate, if tiny, step has now been taken toward the real thing: the creation of a mouse with a human gene for language.

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?

A very detailed account of perfect pitch and its relation to learning language. An informative and interesting site!

Description of words, syntax, etc.

This article discusses human communication with other animals. It states that animals won't be able to remember words like "bacteria" or "economy" because they don't have the brain capacity to understand those words. However, if you tell a dog to "sit", the dog is able to differentiate the sound of that particular word from other verbal signals, and can carry out the action. This is how learning words works. The article also discusses IQ and explains that human brains have been genetically modified for communication, and the size of our brains is also much bigger than expected in animals of the same size.

The article also underscores a quality that differentiates human language from other animal communication: grammatical orderliness. Human languages have word categories such as nouns, verbs, adjectives, adverbs, prepositions, and so on. We can modify word order and word endings to create different tenses so that we can describe events from the past or imaginary ones from the future. This grammatical complexity emerges quite early in child development, beginning in the second year of life and exploding with full force in the third year of life. No nonhuman animal to date has demonstrated the ability to construct sentences with the level of grammatical complexity typical of a three-year-old human child.

Before, linguists thought that language grew and evolved normally, but now, after research, they are now using the analogy that language is like a living creature, using concepts from biology like natural selection, and genetic drift to describe the evolution of language. The researchers now hope that linguists accept these observations/claims made from this new research.

This is about how language grows and changes. Every time someone learns it, it is reproduced.

While brain games can't avert dementia in those genetically inclined toward the condition, one can ensure better brain fitness and long-term health. The brain thrives on continuous stimulation. Here are takeaway tips from the article: 1. Brain exercises should rely on novelty and complexity, including board games that are played with others. 2. All kinds of concentrated activities, like learning a foreign language or how to play a musical instrument, can be fulfilling. 3. Along with exercising and good nutrition, a brain that is fully engaged socially, mentally and spiritually is more resilient. 4. New, interactive learning is helpful. 5. Cognitive training that uses thinking, such as problem solving and learning, like reading a newspaper article and discussing it with a friend, has staying power in the brain - even 10 years after the training ends.

Previously, genetic analysis had indicated that the ancestors of Native Americans left Siberia to migrate across ancient Beringia (the strip of land that once connected Asia and what's now Alaska) about 25,000 years ago, but the earliest evidence of human habitation on North America dates to 15,000 years ago. With ice covering much of Alaska, the ancestors of Native Americans might've lived in Beringia for about 10,000 years before moving on. Now linguistic evidence may help support that theory. A pair of linguistics researchers, Mark Sicoli and Gary Holton, recently analyzed languages from North American Na-Dene family (traditionally spoken in Alaska, Canada and parts of the present-day U.S.) and the Asian Yeneseian family (spoken thousands of miles away, in central Siberia), using similarities and differences between the languages to construct a language family tree. As they note in an article published today in PLOS ONE, they found that the two language families are indeed related-and both appear to descend from an ancestral language that can be traced to the Beringia region. Both Siberia and North America, it seems, were settled by the descendants of a community that lived in Beringia for some time. In other words, Sicoli says, "this makes it look like Beringia wasn't simply a bridge, but actually a homeland-a refuge, where people could build a life."

A 2022 University of Cambridge study conducted by Sahakian, Langley, Chen, et al., and published in the journal _Neurology_, shows that that social isolation is linked to changes in brain structure and cognition - the mental process of acquiring knowledge - it even carries an increased risk of dementia in older adults. Previous research established that brain regions consistently involved in diverse social interactions are strongly linked to networks that support cognition, including the default mode network (which is active when we are not focusing on the outside world), the salience network (which helps us select what we pay attention to), the subcortical network (involved in memory, emotion and motivation) and the central executive network (which enables us to regulate our emotions). This particular study examined how social isolation affects grey matter - brain regions in the outer layer of the brain, consisting of neurons. It investigated data from nearly 500,000 people from the UK Biobank, with a mean age of 57. People were classified as socially isolated if they were living alone, had social contact less than monthly and participated in social activities less than weekly. The study also included neuroimaging (MRI) data from approximately 32,000 people. That data revealed that socially isolated people had poorer cognition, including in memory and reaction time, and lower volume of grey matter in many parts of the brain. These areas included the temporal region (which processes sounds and helps encode memory), the frontal lobe (which is involved in attention, planning and complex cognitive tasks) and the hippocampus - a key area involved in learning and memory, which is typically disrupted early in Alzheimer's disease. We also found a link between the lower grey matter volumes and specific genetic processes that are involved in Alzheimer's disease. Follow-ups with participants 12 years later showed that those who were socially isolated, but not
