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.

    5 STEAM myths debunked

    By Sarah Hillyard
    Reading time: 4 minutes

    STEAM (Science, Technology, Engineering, Art and Maths) sounds like an overwhelming combination of subjects to teach – and only suitable for expert educators. But the reality is doing STEAM is simpler than you think. Here are 5 common STEAM myths and the truth behind them. We also outline a number of simple activities you try with your students.

    1. STEAM requires a lot of time

    STEAM projects encourage curiosity, creativity and collaboration in the classroom – but they have a reputation for being preparation-heavy and for requiring a lot of teaching time and energy.

    But to get the full benefit of STEAM, there’s no need to plan out a full-blown project that lasts a whole month. In fact, you might integrate just one STEAM lesson into your syllabus. Or a lesson could contain a one-off 10-minute STEAM challenge.?

    Here are some easy, low-preparation challenges your classes can take part in:?

    10-minute STEAM challenges:

    • Winter unit: How tall can you build a snowman using paper cups??
    • Shapes theme: Using five toothpicks make a pentagon, two triangles, a letter of the alphabet.?
    • Bug project: Can you create a symmetrical butterfly?

    2. You need fancy materials to do STEAM

    The biggest misconception is around technology. When you think of STEAM, you might imagine you need apps, computers, tablets and robots to teach it successfully. It’s true that you will certainly find STEAM challenges out there that involve extensive supply lists, expensive equipment, knowledge of programming and robotics.?

    However, in reality, you probably have everything you need already. Technology doesn’t have to be expensive or complicated. It can refer to simple, non-electronic tools and machines, too. Think funnels, measuring cups and screwdrivers, for example. You can use low-cost regular classroom or household items and recyclable materials that learners' families can donate. Toilet paper rolls and cardboard boxes are very popular items in STEAM.

    Here is a low-tech activity you can try:?

    Combine engineering, art and math using cardboard and a pair of scissors

    This challenge involves creating 3D self-portrait sculptures in the using only cardboard. First, teach about parts of the face by observing and analyzing some Cubist portraits (eg, explore Georges Braque and Pablo Picasso). Then have learners cut out cardboard shapes and make slits in them to attach together. They create their self-portrait sculptures by fitting the pieces together using the slits so that the final product will stand by itself. Display the self-portraits and talk about them.

    3. STEAM is targeted to older learners

    Young children are naturally curious about the world around them, and STEAM experiences begin very early in life. They explore with their senses and test their hypotheses about the world, just like scientists do. Much of their play is based on engineering skills, such as building houses with LEGO?? bricks. They learn to manipulate tools while they develop their fine motor skills and their awareness of non-electronic technology. They use dramatic play and enjoy getting their hands full of paint while engaged in art. They learn about maths concepts very early on, such as size (big and small toys), quantities of things, and even babies start using the word “more” if they’re still hungry.?

    Check out this simple STEAM experiment to learn about plants and their needs.?

    How do plants eat and drink??

    Have students put water and food dye in a pot. Put a white flower in the water. Ask students to guess what will happen.?

    After a few days, students should check their flowers and observe how it has changed color. They must then record their results. Extend the experiment by asking if they can make their flowers two colors.
