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.

    Effective international communication is crucial in the world of global commerce. In today's borderless marketplace, companies need to be linguistically flexible to be successful. For HR managers and business practitioners, comprehensive language evaluations are not just an add-on but a vital duty that can enhance your organization's success in the international market.

    This guide will take you through the crucial role of language assessment in business. It will discuss why language assessment is important, how to effectively implement it, its benefits for students and business professionals, and the current tools and technologies available. By the end, you will have the knowledge to identify the significance of language assessment in your business and make informed decisions that reflect the essential role of linguistic ability in the modern global economy.

    Why language assessment matters

    Enhancing communication effectiveness

    Effective communication is the lifeblood of any successful business. When diverse teams come together, be it in an office, on a shop floor, or at a virtual meeting, the ability to exchange information clearly and concisely can mean the difference between streamlined operations and costly misunderstandings. Language assessment ensures that employees possess the necessary language skills needed to communicate across teams and with clients worldwide.

    Global market competitiveness

    Accessing international markets hinges largely on the language capabilities of your workforce. Assessing language skills not only amplifies your organization's ability to engage with prospective clients and partners but also ensures that the customer experience is seamlessly delivered, regardless of the customer's primary language.

    Talent acquisition and retention

    Proper language assessments play a pivotal role in the recruitment process. They aid in identifying candidates with the language proficiencies required for specific roles, such as those involving international correspondence or multilingual customer support. By enabling a streamlined and objective measurement of language ability, your business can attract and retain talent, securing a competitive edge in a multilingual talent pool.

    Types of language assessments

    Proficiency tests

    Proficiency tests are the benchmarks for evaluating a person’s overall language capability. This category includes tests that cover all language skills, such as reading, writing, listening and speaking, like the Versant tests offered by ɫèAV. These tests provide a comprehensive analysis that helps gauge an individual's ability to function effectively in a language, both in academic settings, the workplace and everyday contexts.

    Interviews

    Conversational skills and the application and comprehension of language in real-world scenarios play a significant role in many job roles. Structured interviews that focus on language are a vital component of the language assessment suite. These interviews typically evaluate oral and sometimes written language skills, providing context-specific insight into how these skills might translate in a professional setting.

    Role-playing scenarios

    Simulations that mimic workplace interactions provide an immersive method of assessing language skills beyond language proficiency tests. Candidates engage in practical scenarios that mirror the challenges and dynamics of a business environment, which is particularly valuable for assessing their ability to manage real-time communication under pressure.

    Implementing language assessment

    Best practices for HR managers

    When starting your language assessment program, begin with a thorough needs analysis. This involves identifying which roles require language proficiency, to what level and in which languages. Then, select or develop an assessment that aligns with these requirements. It's also important to provide clear instructions and support for candidates, ensuring that the assessment process is transparent and equitable.

    Training and development strategies

    Personalized learning plans can be a game-changer for employees who require language improvements. Identify the areas for development, set achievable goals, and incorporate regular assessments to measure progress. This approach ensures that training is targeted and effective, helping employees advance their language skills in a way that's both strategic and supportive.

    Benefits for business professionals

    Career advancement opportunities

    Proficient multilingualism can open doors to international career opportunities and is a key differentiator in many sectors. A dedication to mastering a foreign language can lead to personal and professional growth, including access to leadership positions and broader responsibilities.

    Cross-cultural competence

    Language proficiency is closely tied to cross-cultural understanding and competence. Business professionals who possess these abilities can traverse cultural boundaries with sensitivity and insight, essential for global leadership and successful collaborations in multicultural teams.

    Enhanced collaboration

    Clear and expressive communication fosters an environment of trust and collaboration. By investing in the linguistic abilities and listening skills of your teams, you're not only improving the performance of individual employees but also elevating the collective capacity for innovation and problem-solving within your organization.
