"Preschool children who hear their parents describe the size and shape of objects and then use those words themselves perform on average 23 percent better on spatial skill tests later on."

Fascinating article on language learning using an app called Memrise. The company's goal: to take all of cognitive science's knowhow about what makes information memorable, and combine it with all the knowhow from social gaming about what makes an activity fun and addictive, and develop a web app that can help anyone memorise anything. Two takeaways for language learning, and acquiring and retaining any subject matter: 1. Elaborative encoding. The more context and meaning you can attach to a piece of information, the likelier it is that you'll be able to fish it out of your memory at some point in the future. And the more effort you put into creating the memory, the more durable it will be. One of the best ways to elaborate a memory is to try visually to imagine it in your mind's eye. If you can link the sound of a word to a picture representing its meaning, it'll be far more memorable than simply learning the word by rote. Create mnemonics for vocabulary. 2. "Spaced repetition". Cognitive scientists have known for more than a century that the best way to secure memories for the long term is to impart them in repeated sessions, distributed across time, with other material interleaved in between. If you want to make information stick, it's best to learn it, go away from it for a while, come back to it later, leave it behind again, and once again return to it - to engage with it deeply across time. Our memories naturally degrade, but each time you return to a memory, you reactivate its neural network and help to lock it in. One study found that students studying foreign language vocabulary can get just as good long-term retention from having learning sessions spaced out every two months as from having twice as many learning sessions spaced every two weeks. To put that another way: you can learn the same material in half the total time if you don't try to cram.

For bilinguals, because both languages are active in the brain, the act of keeping the two languages separate sharpens the executive control system. Strengthening this area may have long-term benefits: namely, performing better on a variety of cognitive tasks and possibly delaying the onset of dementia later in life.

Abstract: The critical period hypothesis holds that first language acquisition must occur before cerebral lateralization is complete, at about the age of puberty. One prediction of this hypothesis is that second language acquisition will be relatively fast, successful, and qualitatively similar to first language only if it occurs before the age of puberty.

People familiar with more than one language showed a later onset of dementia, according to a new study from Indian researchers. Multilingualism appeared to stave off dementia onset in several diagnostic categories, including front temporal and vascular dementia as well as Alzheimer's, according to the researchers' report in the online version of Neurology.

"Psychologists had already suspected that language was important for understanding numbers. Earlier studies of two tribes in the Amazon - one that had no words for numbers greater than five and another whose counting system seemed to go "one, two, many" - showed that people in those tribes had trouble reporting exactly how many objects were placed in front of them. But in those cultures, which don't have monetary systems, there might be no need to represent large numbers exactly. The question posed was whether language kept those Amazonian people from counting, or a lack of cultural pressure. To address that question, Spaepen and colleagues turned to Nicaraguan homesigners, deaf people who communicate with their hearing friends and relatives entirely through made-up hand gestures."

This article is relevant to the Genie case, outlining the many ways isolation is physically bad for us. Chronically lonely people have higher blood pressure, are more vulnerable to infection, and are also more likely to develop Alzheimer's disease and dementia. Loneliness also interferes with a whole range of everyday functioning, such as sleep patterns, attention and logical and verbal reasoning. The mechanisms behind these effects are still unclear, though what is known is that social isolation unleashes an extreme immune response - a cascade of stress hormones and inflammation. This response might've been biologically advantageous for our early ancestors, when being isolated from the group carried big physical risks, but for modern humans, the outcome is mostly harmful. A 1957 McGill University study, recreated in 2008 by Professor Ian Robbins, head of trauma psychology at St George's Hospital, Tooting, found that after only a matter of hours, people deprived of perceptual stimulation and meaningful human contact, started to crave stimulation, talking, singing or reciting poetry to themselves to break the monotony. Later, many of them became anxious or highly emotional. Their mental performance suffered too, struggling with arithmetic and word association tests. In addition, subjects started hallucinating. The brain is used to processing large quantities of data, but in the absence of sensory input, Robbins states that "the various nerve systems feeding in to the brain's central processor are still firing off, but in a way that doesn't make sense. So after a while the brain starts to make sense of them, to make them into a pattern." It tries to construct a reality from the scant signals available to it, yet it ends up building a fantasy world.

An infant's mother tongue creates neural patterns that the unconscious brain retains years later, even if the child totally stops using the language, (as can happen in cases of international adoption) according to a new joint study by scientists at the Montreal Neurological Institute and Hospital. The study offers the first neural evidence that traces of the "lost" language remain in the brain and suggests that early-acquired information is not only maintained in the brain, but unconsciously influences brain processing for years, perhaps for life -- potentially indicating a special status for information acquired during optimal periods of development. This could counter arguments not only within the field of language acquisition, but across domains, that neural representations are overwritten or lost from the brain over time.

The largest study so far to ask whether speaking two languages might delay the onset of dementia symptoms in bilingual patients as compared to monolingual patients has reported a robust result. Bilingual patients suffer dementia onset an average of 4.5 years later than those who speak only a single language.

Schizophrenia is a very disabling psychiatric illness affecting about 2 to 3 million Americans. Contrary to popular perception, it has nothing to do with a "split personality." Schizophrenia is a chronic brain disorder involving "positive" and "negative" symptoms. Positive symptoms include hallucinations (hearing voices or seeing visions that aren't real), delusions (fixed false beliefs), and disorganized thinking or speech. A recent study in the Archives of General Psychiatry by Paul Grant, Aaron Beck, and their colleagues found that a modified version of cognitive-behavioral therapy (CBT), a specific type of talk therapy, can produce clinically significant improvement in patients with schizophrenia. Importantly, significant improvement was seen in certain negative symptoms-apathy/avolition (lack of drive)-as well as in positive symptoms. These results are impressive, especially considering that the participants had been ill for an average of 18 years and suffered from severe symptoms. In this study, study participants were divided into two groups. One group received CBT in addition to "standard treatment," which included treatment with antipsychotic medications. The other group received standard treatment alone. CBT has been shown to be effective in a variety of psychiatric illnesses. It uses pragmatic techniques to help a person correct inaccurate or dysfunctional thoughts and emotions by promoting critical comparison of those thoughts with observable facts. For example, if a person believes that he/she is "doing absolutely nothing," one CBT technique would be to encourage the person to keep a detailed diary of daily activities. The therapist would later review this diary with the patient and facts would be compared to perceptions. Homework assignments would include strategies to increase productive activities. In the study mentioned above, the researchers focused CBT "on identifying and promoting concrete goals for improving quality of life and

The key takeaways: 1. Ensuring rich, socially-contextualized language exposure in both languages. Pediatricians advise non-English-speaking parents to read aloud and sing and tell stories and speak with their children in their native languages, so the children get that rich and complex language exposure, along with sophisticated content and information, rather than the more limited exposure you get from someone speaking a language in which the speaker is not entirely comfortable. 2. Exposure has to be person-to-person; screen time doesn't count for learning language in young children - even one language - though kids can learn content and vocabulary from educational screen time later on. 3. It does take longer to acquire two languages than one, says Dr. Erika Hoff, a developmental psychologist who specializes in early language development. "A child who is learning two languages will have a smaller vocabulary in each than a child who is only learning one; there are only so many hours in the day, and you're either hearing English or Spanish," Dr. Hoff said. The children will be fine, though, she said. They may mix the languages, but that doesn't indicate confusion. "Adult bilinguals mix their languages all the time; it's a sign of language ability," she said. 4. If exposed to the target languages at a younger age, children generally will sound more nativelike. On the other hand, older children may learn more easily. Gigliana Melzi, a developmental psychologist and associate professor of applied psychology, states, "The younger you are, the more head start you have," she said. "The older you are, the more efficient learner you are, you have a first language you can use as a bootstrap."

This article essentially describes how research has shown that 18-24 months of age is the prime time to help their verbal communication skills in later years.

An interview with Ellen Bialystok, a cognitive neuroscientist, about the advantages of being bilingual.

A cognitive neuroscientist, Ellen Bialystok has spent almost 40 years learning about how bilingualism sharpens the mind. Her good news: Among other benefits, the regular use of two languages appears to delay the onset of Alzheimer's disease symptoms. Dr. Bialystok, 62, a distinguished research professor of psychology at York University in Toronto, was awarded a $100,000 Killam Prize last year for her contributions to social science.

"In our next studies , we looked at the medical records of 400 Alzheimer's patients. On average, the bilinguals showed Alzheimer's symptoms five or six years later than those who spoke only one language. This didn't mean that the bilinguals didn't have Alzheimer's. It meant that as the disease took root in their brains, they were able to continue functioning at a higher level. They could cope with the disease for longer." No other website I have found has so comprehensively covered the various benefits of being bilingual. This is a concise interview that displays that bilingual people are not only better at multitasking but can also delay the onset of Alzheimer's by up to 5 years.

Al-Sayyid is a village in Israel, populated by congenitally-deaf people. Over the past 75 years, the villagers have created an entirely new and unique language, Al-Sayyid Bedouin Sign Language (ABSL). The seeds emerged spontaneously among the first deaf residents and, three generations later, it has flowered into a complex language capable of expressing anything a spoken one can. Since its discovery by linguists in 2000, ABSL has captivated researchers driven by two fundamental questions: how did language emerge, and what can that tell us about the nature of the human mind? ABSL offers a unique opportunity to test a theory that has dominated linguistics since the 1950s. Put forth by Noam Chomsky, it claims that language is an innate and uniquely human trait, programmed into our genes. Children are born with a "language instinct" that compels them to effortlessly acquire whatever language (or languages) they are immersed in as toddlers.

Over the last 70 years, researchers have tried to gauge the effect on an individual of having an unusual name. It is thought that our identity is partly shaped by the way we are treated by other people - a concept psychologists call the "looking-glass self" - and our name has the potential to colour our interactions with society. Early studies found that men with uncommon first names were more likely to drop out of school and be lonely later in life. One study found that psychiatric patients with more unusual names tended to be more disturbed. But more recent work has presented a mixed picture. Richard Zweigenhaft, a psychologist at Guilford College in the US, pointed out that wealthy, oddly-named Americans are more likely to find themselves in Who's Who. He found no consistent bad effects of having a strange name, but noted that both common and unusual names are sometimes deemed desirable. Conley, who is a sociologist at New York University, says that children with unusual names may learn impulse control because they may be teased or get used to people asking about their names. "They actually benefit from that experience by learning to control their emotions or their impulses, which is of course a great skill for success."

In a group of internationally adopted children with cleft lip and/or palate, speech at age five is impaired compared to a corresponding group of children born in Sweden, a study shows. The adopted children also need more extensive surgery, which may be due to their surgical interventions taking place later in life.
