Measurable changes in brain activity during first few months of studying a new language

 A study with first-time learners of Japanese has measured how brain activity changes after just a few months of studying a new language. The results show that acquiring a new language initially boosts brain activity, which then reduces as language skills improve.

"In the first few months, you can quantitatively measure language-skill improvement by tracking brain activations," said Professor Kuniyoshi L. Sakai, a neuroscientist at the University of Tokyo and first author of the research recently published in Frontiers in Behavioral Neuroscience.

Researchers followed 15 volunteers as they moved to Tokyo and completed introductory Japanese classes for at least three hours each day. All volunteers were native speakers of European languages in their 20s who had previously studied English as children or teenagers, but had no prior experience studying Japanese or traveling to Japan.

Volunteers took multiple choice reading and listening tests after at least eight weeks of lessons and again six to fourteen weeks later. Researchers chose to assess only the "passive" language skills of reading and listening because those can be more objectively scored than the "active" skills of writing and speaking. Volunteers were inside a magnetic resonance imaging (MRI) scanner while taking the tests so that researchers could measure local blood flow around their brain regions, an indicator of neuronal activity.

"In simple terms, there are four brain regions specialized for language . Even in a native, second or third language, the same regions are responsible," said Sakai.

Those four regions are the grammar center and comprehension area in the left frontal lobe as well as the auditory processing and vocabulary areas in the temporo-parietal lobe. Additionally, the memory areas of the hippocampus and the vision areas of the brain, the occipital lobes, also become active to support the four language-related regions while taking the tests.

During the initial reading and listening tests, those areas of volunteers' brains showed significant increases in blood flow, revealing that the volunteers were thinking hard to recognize the characters and sounds of the unfamiliar language. Volunteers scored about 45% accuracy on the reading tests and 75% accuracy on the listening tests (random guessing on the multiple choice tests would produce 25% accuracy).

Researchers were able to distinguish between two subregions of the hippocampus during the listening tests. The observed activation pattern fits previously described roles for the anterior hippocampus in encoding new memories and for the posterior hippocampus in recalling stored information.

At the second test several weeks later, volunteers' reading test scores improved to an average of 55%. Their accuracy on the listening tests was unchanged, but they were faster to choose an answer, which researchers interpret as improved comprehension.

Comparing results from the first tests to the second tests, after additional weeks of study, researchers found decreased brain activation in the grammar center and comprehension area during listening tests, as well as in the visual areas of the occipital lobes during the reading tests.

"We expect that brain activation goes down after successfully learning a language because it doesn't require so much energy to understand," said Sakai.

Notably during the second listening test, volunteers had slightly increased activation of the auditory processing area of their temporal lobes, likely due to an improved "mind's voice" while hearing.

"Beginners have not mastered the sound patterns of the new language, so cannot hold in memory and imagine them well. They are still expending a lot of energy to recognize the speech in contrast to letters or grammar rules," said Sakai.

This pattern of brain activation changes -- a dramatic initial rise during the learning phase and a decline as the new language is successfully acquired and consolidated -- can give experts in the neurobiology of language a biometric tool to assess curricula for language learners or potentially for people regaining language skills lost after a stroke or other brain injury.

"In the future, we can measure brain activations to objectively compare different methods to learn a language and select a more effective technique," said Sakai.

Until an ideal method can be identified, researchers at UTokyo recommend acquiring a language in an immersion-style natural environment like studying abroad, or any way that simultaneously activates the brain's four language regions.

This pattern of brain activation over time in individual volunteers' brains mirrors results from previous research where Sakai and his collaborators worked with native Japanese-speaking 13- and 19-year-olds who learned English in standard Tokyo public school lessons. Six years of study seemed to allow the 19-year-olds to understand the second language well enough that brain activation levels reduced to levels similar to those of their native language.

The recent study confirmed this same pattern of brain activation changes over just a few months, not years, potentially providing encouragement for anyone looking to learn a new language as an adult.

Internet use reduces study skills in university students

Research conducted at Swansea University and the University of Milan has shown that students who use digital technology excessively are less motivated to engage with their studies, and are more anxious about tests. This effect was made worse by the increased feelings of loneliness that use of digital technology produced.

Two hundred and eighty-five university students, enrolled on a range of health-related degree courses, participated in the study. They were assessed for their use of digital technology, their study skills and motivation, anxiety, and loneliness. The study found a negative relationship between internet addiction and motivation to study. Students reporting more internet addiction also found it harder to organise their learning productively, and were more anxious about their upcoming tests. The study also found that internet addiction was associated with loneliness, and that this loneliness made study harder.

Professor Phil Reed of Swansea University said: "These results suggest that students with high levels of internet addiction may be particularly at risk from lower motivations to study, and, hence, lower actual academic performance."

About 25% of the students reported that they spent over four hours a day online, with the rest indicating that they spent between one to three hours a day. The main uses of the internet for the student sample were social networking (40%) and information seeking (30%).

Professor Truzoli of Milan University said: "Internet addiction has been shown to impair a range of abilities such as impulse control, planning, and sensitivity to rewards. A lack of ability in these areas could well make study harder."

In addition to the links between levels of internet addiction and poor study motivation and ability, internet addiction was found to be associated with increased loneliness. The results indicated that loneliness, in turn, made studying harder for the students.

The study suggests that loneliness plays a large role in positive feelings about academic life in higher education. The poorer social interactions that are known to be associated with internet addiction make loneliness worse, and, in turn, impact on motivation to engage in a highly social educational environment such as a university.

An hour or two of outdoor learning every week increases teachers' job satisfaction

A Swansea University study has revealed how as little as an hour a week of outdoor learning has tremendous benefits for children and also boosts teachers' job satisfaction.

Through interviews and focus groups, researchers explored the views and experiences of pupils and educators at three primary schools in south Wales that had adopted an outdoor learning programme, which entailed teaching the curriculum in the natural environment for at least an hour a week.

Interviews were held with headteachers and teachers, and focus groups were conducted with pupils aged 9-11 both before and during the implementation of an outdoor learning programme within the curriculum.

The schools in the study reported a variety of benefits of outdoor learning for both the child and the teacher and for improving health, wellbeing, education and engagement in school.

Lead author of the study Emily Marchant, a PhD researcher in Medical Studies at Swansea University, explained: "We found that the pupils felt a sense of freedom when outside the restricting walls of the classroom. They felt more able to express themselves, and enjoyed being able to move about more too. They also said they felt more engaged and were more positive about the learning experience. We also heard many say that their well-being and memory were better, and teachers told us how it helped engage all types of learners."

The benefits of outdoor education for children are well documented, but a finding of this study is the impact that the outdoor learning programme had on teachers.

Emily said: "Initially, some teachers had reservations about transferring the classroom outdoors but once outdoor learning was embedded within the curriculum, they spoke of improved job satisfaction and personal wellbeing. This is a really important finding given the current concerns around teacher retention rates. Overall, our findings highlight the potential of outdoor learning as a curriculum tool in improving school engagement and the health, wellbeing and education outcomes of children.

"The schools within our study have all continued with regular outdoor learning within the curriculum. With support and recognition from education inspectorates of the wider benefits to children's development and education, outdoor learning could be set within the primary school curriculum."

Making mistakes while studying actually helps you learn better

When learning something new, there are instances where trial and error helps rather than hinders, according to recent findings by Baycrest researchers.

Contrary to popular belief, when a person makes a mistake while learning, it improves their memory for the right information, but only if the error is close to the correct answer, according to a study published in the journal, Memory.

"Our research found evidence that mistakes that are a 'near miss' can help a person learn the information better than if no errors were made at all," says Dr. Nicole Anderson, senior author on the paper and senior scientist at Baycrest's Rotman Research Institute. "These types of errors can serve as stepping stones to remembering the right answer. But if the error made is a wild guess and out in left field, then a person does not learn the correct information as easily."

These findings could help with improving education for not only younger adults, but also late-life learners.

In one of the studies reported in the paper, researchers recruited 32 young adults with no Spanish background to guess the English definition of certain Spanish words. The Spanish words selected either resembled an English word with a similar meaning (such as careera, which means degree) or the word looked like an English word, but meant something different (such as carpeta, which resembles carpet, but means folder).

Participants were shown the Spanish words and asked to guess its meaning. Then, they were briefly shown the correct translation, before being shown another Spanish word. After repeating this process with 16 Spanish words, participants had a short break before their memory for the translations was tested.

Researchers found that people were better able to remember the correct translations for Spanish words that were similar to the English word. They had greater difficulty recalling the meaning for words that looked misleading.

"Based on these findings, someone studying for an exam should only take practice quizzes after reviewing the material," says Dr. Anderson, who is also an associate professor of psychology and psychiatry at the University of Toronto. "If a person takes a practice test and is unfamiliar with the content, they risk making guesses that are nowhere near the right answer. This could make it harder for them to learn the correct information later."

Even if a person makes a mistake while testing themselves, as long as their error is close to the right answer, they're more likely to remember the right information, adds Dr. Anderson.
