Being bilingual can help keep your brain in good condition

Learning and understanding a new language is one of the most challenging things that your brain can do. But as well as the advantage of acquiring another language, it appears that the effort of giving your brain a good workout today by being bilingual could keep it in better condition in later life.

Research led by Dr. Daniela Perani, a professor of psychology at in Milan, found that people who speak two or more languages seem to weather the ravages of Alzheimer’s disease better compared to people who have only mastered one language. Alzheimer’s is a progressive mental deterioration that can begin in middle or old age due to generalized brain degeneration.

The study involved 85 people with Alzheimer’s – half of whom spoke both German and Italian and half who spoke only one language. The researchers found that bilingual patients had greater connectivity in key brain areas. This was especially in the part of the brain that governs “executive control” – a set of necessary behavioral cognitive processes that include problem-solving, working memory, reasoning and attentional control. The study also noted that the bilingual Alzheimer’s patients showed less severe symptoms of the disease.

The study concluded: “Our findings suggest that the effects of speaking two languages are more powerful than both age and education in providing a protection against cognitive decline.”

Bilingualism and the brain

Although Alzheimer’s disease is currently incurable, the study supports a popular theory that people who have higher levels of education function longer with little manifestation of the illness. Part of the reason why bilingual brains may be better at resisting Alzheimer’s could be due to a lifetime of switching between languages daily.

Learning and speaking more than one language changes how the brain carries out tasks that require focus and concentration on a certain piece of information without being distracted. It can also increase the density of white matter (connections) in the brain, meaning that there are more connections between brain parts, thus making this part of the brain more resistant to degeneration.

This is supported by a study conducted by a team led by Professor Ana Inés Ansaldo at the , which suggests that bilingual people have more robust and more efficient brains compared to those who only speak one language. This is one of the reasons why a bilingual brain can be a buffer against aging and dementia.

They recruited elderly people, half of whom spoke only one language and the other half who had learned a second language between the ages of 11 and 18. All performed equally well on a task that involved focusing on an object's color while ignoring its position, but brain scans revealed a big difference in how they processed the task.

“While bilinguals were recruiting very specific brain areas and a small number of areas to perform the task, monolinguals were recruiting a much larger number of areas that were consuming much more resources. And the networks they were using were very, very complex,” says Professor Ansaldo. “That led us to think that the bilingual brain was more efficient in terms of the amount of resources that bilingual people require to do complex tasks as opposed to the monolingual brain.”

The study concludes that bilingualism shapes the brain in a different way or how people approach complex tasks. It could be because bilinguals must inhibit the language they are not using to focus on the one that they are using.

    The advantages of online distance learning

    By Mike Rost

    The technological component of learning is constantly growing. More and more classes are taking place online – yet rather than simply being a substitute for classroom courses, they can be blended with a classroom-based approach. This often offers students a more engaging and motivating experience. This post talks about the advantages of online learning, why teachers find it useful and why students enjoy it.

    Distance learning versus classroom courses

    Typically, there are two sets of teachers interested in experimenting with online teaching:

    • Those who are considering using distance learning courses for students who can’t attend classes.
    • Those who are looking to supplement their classroom teaching with more interactive, or personalized online components.

    Yet regardless of the category they fall into, they’ll often ask: “What can distance learning courses provide that classroom courses can’t?”.

    And this is the right question to ask. Looking at the relative advantages of online courses helps us discern what is the best use of classroom time for learning and what is the best use of online time for learning.

    Knowing this allows us to make better decisions about how and when to use online learning. Instead of simply adopting an online course, adding online components just because they look attractive, or using great technology just because it alleviates scheduling problems, we can choose them for the added value they provide.

    The strengths of classroom-based learning versus online learning

    The strengths of a classroom-based course are:

    1. Easier community building.
    2. Direct access to a live teacher for inspiration, guidance and feedback.
    3. More 'live' opportunities for communicative practice with other students.
    4. Provision of a structured schedule.

    As for the strengths of a distance learning course, the following come to mind. They:

    1. Provide easier access to course resources.
    2. Offer greater convenience for the teacher and learner, and offer flexibility in scheduling.
    3. Can be personalized – that is, teachers can cater to each student’s proficiency level and learning goals by delivering different online resources (including videos, readings, and listenings) to individual students so they can work on them in their own time.

    However, distance learning courses have some less obvious advantages, too. Distance learning courses have shown the following trends, which have completely changed the way to see and use online learning:

    Increased engagement

    Number one is the rise in engagement. A well-designed distance course is aimed directly at the individual learner: there is much more practice time and immediate feedback, particularly for listening and speaking tasks. We often find that shy students and those who feel unable to participate in a classroom environment are more willing to engage with the teacher and other students in online courses.

    Improved concentration

    Secondly, online courses improve concentration, which, as all teachers know, is a continual problem in classrooms. Rather than being directed on what to do, students working online can select what activities to engage in, for how long, and in what sequence, which helps them stay focused.

    Easier assessment

    The third advantage, which is vital for a teacher, is the ease and fluidity of tracking progress. In classrooms, it’s hard to track how students progress over a whole semester, much less in each class. In online distance learning, you get constant monitoring of how well students are doing on individual tasks and progress checks, no matter what learning management system you’re using.

    Why learners choose online courses

    We’ve seen the potential reasons teachers may incorporate distance learning materials. But why do learners choose online courses over classroom ones?

    Choice is an important aspect of – and the only way that students are going to learn is if they feel engaged. Give them choices in activities, homework, schedules, tests and even grading.

    For example, if teaching a class on human rights, in which students watch a short video and write a text, you could give students a choice of two videos, rather than directing them to watch a particular video. And in an exam, maybe offer a choice of different reading materials or essay topics to write on.

    What’s more, giving students a choice of a distance learning course over a classroom course, a blended classroom online course, or even a choice of activities can improve motivation and increase engagement. Just make sure not to overwhelm them with too many choices!
