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.

    Why don’t my students speak English in class?

    By Silvia Minardi
    Reading time: 3 minutes

    Last year, I contributed to a national research project with an article titled “?”. The title originated from a concern expressed by a language teacher involved in the project, highlighting a common challenge faced by numerous language teachers. The difficulty of developing learners’ production and interaction skills is a well-known issue in language education.

    Large and increasingly diverse classes, limited time, and learners’ reluctance to speak in class are significant hurdles. During pair and group work, students often revert to their first language (L1), they lack confidence in speaking activities and end up avoiding all interaction in English. These observations are consistent with recent Global Scale of English (GSE) research findings, which indicate that 52% of English learners leave formal education without confidence in their speaking skills.

    Factors contributing to learners’ reluctance

    Several factors contribute to students’ reluctance to speak English in class. Psychological barriers such as lack of motivation, shyness, low self-confidence, fear of making mistakes, anxiety and concerns about negative evaluation play a crucial role. Linguistic challenges, including limited vocabulary, poor pronunciation, and insufficient grammatical skills, further exacerbate the problem.

    Task-related issues can also hinder speaking, especially when tasks are not well-matched to the learner’s proficiency level or focus more on accuracy than communication. Additionally, the classroom environment may not always be conducive to speaking, particularly for learners who need more time to formulate their thoughts before speaking.

    Positive teacher impact

    Fortunately, teachers can positively influence these intertwined factors. By creating a supportive classroom atmosphere and implementing well-designed tasks that prioritize communication over perfection, teachers can encourage reluctant students to participate more actively in speaking activities.

    Leveraging technology: Mondly by app

    One effective tool that can help address these challenges is Mondly by app. This learning companion is especially beneficial for learners who are hesitant to speak in class. Mondly by app offers over 500 minutes of speaking practice, encouraging learners to use English in real-life situations and tasks that prioritize action and communication over accuracy. This approach allows for mistakes - they are part of the game - thus fostering a positive mindset, which is essential if we want to enhance our learners’ speaking skills.

    AI-powered conversations

    A standout feature of Mondly by app is its AI-powered conversation capability, thanks to advanced speech recognition software. This flexibility helps build self-confidence and allows students to experiment with various production and interaction strategies.

    Comprehensive skill development

    Mondly by app is designed not only for speaking but also to develop all four language skills—listening, reading, writing and speaking—and is aligned with the Global Scale of English. The vocabulary for each topic is selected from the GSE vocabulary database, ensuring that learners are exposed to level-appropriate words and phrases.

    Integration into classroom teaching

    To facilitate the integration of Mondly by app into classroom teaching, three GSE mapping booklets have recently been published. These booklets cater to different proficiency levels:

    • Beginner (GSE range: 10-42 / CEFR level: A1-A2+)
    • Intermediate (GSE range: 43-58 / CEFR level: B1-B1+)
    • Advanced (GSE range: 59-75 / CEFR level: B2-B2+)

    These resources provide practical guidance on how to incorporate Mondly by app into lesson plans effectively, ensuring that the tool complements classroom activities and enhances overall language learning.

    Conclusion

    Encouraging students to speak English in class is a multifaceted challenge, but it is not insurmountable. By understanding the various factors that contribute to learners’ reluctance and leveraging innovative tools like Mondly by app, teachers can create a more engaging and supportive learning environment. This approach not only boosts students’ confidence in their speaking abilities but also fosters a more inclusive and interactive classroom atmosphere.

    Embracing technology and aligning teaching practices with modern educational standards, such as the Global Scale of English, can lead to significant improvements in language proficiency and student engagement.
