This article examines Nadine Gaab's 2014 study which established a connection - in both children and adults - between learning to play an instrument and improved executive functioning, like problem-solving, switching between tasks and focus. The article also cites the research of neuropsychologist Ani Patel, who advances the OPERA theory of music's benefits for learning. Patel notes "music is not an island in the brain cut off from other things, that there's overlap, that's the 'O' of OPERA, between the networks that process music and the networks that are involved in other day-to-day cognitive functions such as language, memory, attention and so forth," he says. "The 'P' in OPERA is precision. Think about how sensitive we are to the tuning of an instrument, whether the pitch is in key or not, and it can be painful if it's just slightly out of tune." That level of precision in processing music, Patel says, is much higher than the level of precision used in processing speech. This means, he says, that developing our brains' musical networks may very well enhance our ability to process speech. "And the last three components of OPERA, the 'E-R-A,' are emotion, repetition and attention," he says. "These are factors that are known to promote what's called brain plasticity, the changing of the brain's structure as a function of experience."

A Yale-led research team examined the brains of 38 couples engaged in discussion about controversial topics. For the study, the researchers from Yale and the University College of London recruited 38 adults who were asked to say whether they agreed or disagreed with a series of statements such as "same-sex marriage is a civil right" or "marijuana should be legalized." After matching up pairs based on their responses the researchers used an imaging technology called functional near-infrared spectroscopy to record their brain activity while they engaged in face-to-face discussions. Their findings: When two people agree, their brains exhibit a calm synchronicity of activity focused on sensory areas of the brain, such as the visual system, presumably in response to social cues from their partner. When they disagree, however, many other regions of the brain involved in higher cognitive functions become mobilized as each individual combats the other's argument. Sensory areas of the brain were less active, while activity increased in the brain's frontal lobes, home of higher order executive functions. Joy Hirsch, Elizabeth Mears and House Jameson Professor of Psychiatry and professor of comparative medicine and neuroscience, as well as senior author of the study, said that in discord, two brains engage many emotional and cognitive resources "like a symphony orchestra playing different music." In agreement, there "is less cognitive engagement and more social interaction between brains of the talkers, similar to a musical duet."

BEING bilingual has some obvious advantages. Learning more than one language enables new conversations and new experiences. But in recent years, psychology researchers have demonstrated some less obvious advantages of bilingualism, too. For instance, bilingual children may enjoy certain cognitive benefits, such as improved executive function - which is critical for problem solving and other mentally demanding activities.

LAST week, Johnson took a look at some of the advantages of bilingualism. These include better performance at tasks involving "executive function" (which involve the...

Recognition of subtle emotional cues may be developmental, according to neurological research. At the McLean Hospital in Belmont, Mass., Deborah Yurgelun-Todd and a group of researchers have studied how adolescents perceive emotion as compared to adults. The scientists looked at the brains of 18 children between the ages of 10 and 18 and compared them to 16 adults using functional magnetic resonance imaging (fMRI). Both groups were shown pictures of adult faces and asked to identify the emotion on the faces. Using fMRI, the researchers could trace what part of the brain responded as subjects were asked to identify the expression depicted in the picture. The results surprised the researchers. The adults correctly identified the expression as fear. Yet the teens answered "shocked, surprised, angry." Moreover, teens and adults used different parts of their brains to process what they were feeling. The teens mostly used the amygdala, a small almond shaped region that guides instinctual or "gut" reactions, while the adults relied on the frontal cortex, which governs reason and planning. As the teens got older, however, the center of activity shifted more toward the frontal cortex and away from the cruder response of the amygdala. Yurgelun-Todd, director of neuropsychology and cognitive neuroimaging at McLean Hospital believes the study goes partway to understanding why the teenage years seem so emotionally turbulent. The teens seemed not only to be misreading the feelings on the adult's face, but they reacted strongly from an area deep inside the brain. The frontal cortex helped the adults distinguish fear from shock or surprise. Often called the executive or CEO of the brain, the frontal cortex gives adults the ability to distinguish a subtlety of expression: "Was this really fear or was it surprise or shock?" For the teens, this area wasn't fully operating.

When sending text messages on their mobile phone to friends, children often use a special type of register, which is called textese. This register allows the omission of words and the use of textisms: instances of non-standard written language such as 4ever (forever). Previous studies have shown that textese has a positive effect on children's literacy abilities. In addition, it is possible that children's grammar system is affected by textese as well, as grammar rules are often transgressed in this register.

Children aged four and younger who speak two languages or are learning a second have more rapid improvements in inhibitory control, a study by the University of Oregon has said. Inhibitory control is the ability to stop a hasty reflexive response in behaviour or decision-making and use higher control to react in a more adaptive way. "Inhibitory control and executive function are important skills for academic success and positive health outcomes and well-being later in life," said Atika Khurana, the study's co-author and a professor in the Department of Counselling Psychology and Human Services and scientist at the UO's Prevention Science Institute. "The development of inhibitory control occurs rapidly during the preschool years," she said. "Children with strong inhibitory control are better able to pay attention, follow instructions and take turns. "This study shows one way in which environmental influences can impact the development of inhibitory control during younger years."

Alcohol consumption, in small amounts, can improve a person's ability to speak a second language. It was also focused on how people who drank the alcohol had better pronunciation in the second language. Although a small amount of alcohol can be beneficial to using language, it is actually reversed if too much is consumed.

This article outlines a study done that found that low levels of alcohol intake can improve bilingual speaker's use of their second language. Although it may seem alcohol would impair language ability because of the executive functions needed when speaking, alcohol lowers social anxiety and increases confidence - which is helpful when learning to speak a second language.

Dr. Joy Hirsch, head of Memorial Sloan-Kettering Hospital's functional M.R.I. Laboratory, and her graduate student, Karl Kim, found that second languages are stored differently in the human brain, depending on when they are learned. Babies who learn two languages simultaneously, and apparently effortlessly, have a single brain region for generating complex speech, researchers say. But people who learn a second language in adolescence or adulthood possess two such brain regions, one for each language. To explore where languages lie in the brain, Dr. Hirsch recruited 12 healthy bilingual people from New York City. Ten different languages were represented in the group. Half had learned two languages in infancy. The other half began learning a second language around age 11 and had acquired fluency by 19 after living in the country where the language was spoken. With their heads inside the M.R.I. machine, subjects thought silently about what they had done the day before using complex sentences, first in one language, then in the other. The machine detected increases in blood flow, indicating where in the brain this thinking took place. Activity was noted in Wernicke's area, a region devoted to understanding the meaning of words and the subject matter of spoken language, or semantics, as well as Broca's area, a region dedicated to the execution of speech, as well as some deep grammatical aspects of language. None of the 12 bilinguals had two separate Wernicke's areas, Dr. Hirsch said. But there were dramatic differences in Broca's areas, Dr. Hirsch said. In people who had learned both languages in infancy, there was only one uniform Broca's region for both languages, a dot of tissue containing about 30,000 neurons. Among those who had learned a second language in adolescence, however, Broca's area seemed to be divided into two distinct areas. Only one area was activated for each language. These two areas lay close to each other but were always separate, Dr. Hirsch s

I like this article because it also has a statistics at the bottom representing the influence of texts on primary school kids
