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.

    What to look for in an English placement test

    By Jennifer Manning

    If you’re an English teacher, Director of Studies or school owner you’ll know the importance of putting students in the right group. Whether it’s a business English class, exam prep or general English – a placement test is essential. Without one, you’ll teach classes with such varied levels and needs, it’ll be hard to plan an effective lesson.

    Placing students at the wrong level will not only lead to unmotivated learners, but it may also cost your institution money.

    But how exactly do you design a reliable, accurate and easy-to-use test? In this post, we’ll examine the key questions you need to consider before making your own placement test. We’ll also explore what features you need to achieve your goals.

    Problems with traditional placement tests

    Most private language schools (PLSs) and higher education institutions offer new students the opportunity to take a placement test before starting a course. However, these are often just a multiple-choice test, a short interview, or a combination of the two.

    While this does act as a filter helping us group students into similar levels, there are a number of downfalls. Students can guess the answers to multiple-choice questions – and while they might give us a rough idea of their grammar knowledge, these tests don’t consider the four skills: speaking, writing, listening and reading.

    Oral interviews, on the other hand, can give us an indication of the students’ spoken level. However, they also raise questions of objectivity and consistency that even specially trained teachers will struggle to avoid.

    Another big issue with traditional tests is the amount of time they take. Multiple-choice exams are often graded by hand and interviewing every new student uses valuable resources that could be used elsewhere.

    Key questions to consider

    Before you re-design your current test completely, we’ve put together a series of questions to help you think about your objectives, define your needs and explore the challenges you may face.

    Taking a few minutes to think about these things can make the process of finding the right English placement test go more smoothly and quickly. Once you know what you’re looking for, you’ll be ready to make a checklist of the most important features.

    What will your test be used for?

    • Placing incoming ESL students into the appropriate English language program.
    • Measuring students’ progress throughout the school year.
    • Final assessment of students' abilities at the end of the school year (“exit test”).
    • All of the above.

    Is this different from what you use your current test for? How soon are your needs likely to change?

    What skills does your current test measure?

    Does it measure speaking, listening, reading, writing, or all of the above? Are all of these skills measured in separate tests — or in one test?

    • How many students do you need to test at each intake?
    • How many students do you need to test each year? How many do you expect you’ll need to test in three years?

    How quickly do you currently receive test results? How quickly would you like to receive them?

    If you can test your students weeks before the start of the school term, you may have time to wait for results. However, if you are continuously testing students, or have students arriving just before the term begins, you may need to get results much more quickly.

    What features in your current test do you like and dislike?

    Are there things in your current test that you also want in your new test? Is anything missing, or anything that you don’t want your new test to have?

    What resources are available to you?

    Some English language tests require students to have the computer skills needed to take the test online. You may also need a testing lab that has the following:

    • computers
    • a stable internet connection
    • a headset with a built-in microphone
    • a preliminary checklist for placement tests.

    Once you’ve got answers to the questions, you can use the checklist below to make sure your placement test has the features you need. It may also be useful for comparing products if you decide to use an external placement test.

    Online English language testing for employment: Is it secure?

    By Jennifer Manning

    Managers and HR professionals have a global workforce at their fingertips – and now, . This makes adopting a secure English language test for employment more important than ever.

    An online English test enables organizations to assess candidates’ language proficiency from anywhere in the world, screen more applicants, and standardize the hiring process. They also help HR professionals and managers to save time – ensuring only people with the right language skills advance to the interview stage.

    But how can employers be certain these tests are safe? And how easy is it for people to cheat? In this article, we’ll explore a few of the top security concerns we hear, and share what features make online language tests secure.

    What is an online English test?

    An online English test measures how well a job applicant can communicate in English, focusing on speaking, listening, reading and writing skills. They also assess a candidate’s specific English for business skills – for example, how clearly someone can communicate on the phone with clients, or understand what is being said during a conference call.

    Online tests can be taken in a controlled environment – in a testing center with in-person proctors – but also from a job applicant’s personal computer or mobile phone at home. When tests are taken at home, they can be made more secure using virtual proctors or powerful AI monitoring technology.

    Cheating, grading and data security

    When many people think of taking a language test, they imagine the traditional way: students in a large testing center scribbling away with pen and paper. No mobile phones are allowed, and if test-takers are caught cheating, they’ll be flagged by a proctor walking around the room.

    So when managers or HR professionals consider the option of an online English test – taken digitally and often without human supervision – it’s no surprise that many have questions about security. Let’s take a look at some common concerns:

    Is cheating a problem?

    A large number of test takers admit to cheating on their tests. According to research by the International Center for Academic Integrity, 68% of undergraduate students say they’ve cheated on a writing assignment or test, while 43% of graduate students say they have.

    But how easy is it to cheat during a Versant test?

    The truth is, not very. With Versant, exam cheating is actually quite difficult, and test takers would have to outsmart a range of AI monitoring technologies.

    If a verified photo is uploaded to the platform, HirePro’s face recognition technology can compare the live test taker with it. This ensures test takers are who they say they are, and haven’t asked someone else to sit the exam for them. It is the institution’s responsibility to verify the original photo.

    And since Versant tests are monitored using specialized AI algorithms – without a human present – even the slightest suspicious behaviors are flagged for review. For example, Versant notices if a different face appears in the video, or if the camera goes dark. With video monitoring, our platform also flags if the test taker moves from the camera, or looks away multiple times. And we’ll see if someone changes tabs on their computer.

    Finally, the entire test is recorded. When suspicious behavior arises, HR professionals will decide whether to accept or reject the results – or have the candidate retake the test.

    Are scores accurate?

    We’ve all had frustrating experiences with AI. Chatbots don’t always understand what we’re trying to say, and speech recognition technology sometimes isn’t up to par. This leaves many wondering if they should trust AI to grade high-stakes tests – especially when the results could be the difference between someone getting the job, or not.

    Versant uses patented AI technology to grade tests that are trained and optimized for evaluating English language proficiency. It evaluates speaking, listening, reading, writing, and even intelligibility.

    Our AI is trained using thousands of fluent and second-language English speakers. With these models, we’re able to not only evaluate how someone should be assessed but also understand when they’ve mispronounced words or have made another mistake. Using all this information, a candidate’s final score is evaluated based on more than 2000 data points.

    Do online tests follow GDPR standards?

    HR professionals and managers deal with sensitive personal information every day. This includes each job applicant’s name, full address, date of birth, and sometimes even their social security number. The HR tools they implement therefore must also keep this data secure.

    Most importantly, it must follow GDPR standards. The data must be gathered with consent and protected from exploitation. With Versant, test-taker data is securely stored and follows all .

    All our data is encrypted at rest and in transmission. Versant assessment data is stored in the US and HirePro, our remote monitoring partner, stores the proctoring data in either Singapore or Europe, depending on customer needs. Both systems are GDPR compliant.

    Versant: a secure English language test

    ճ Versant automated language test is powered by patented AI technology to ensure the most accurate results for test takers and employers alike. Even better, our remote testing lets HR professionals securely and efficiently assess candidates worldwide, 24/7 – and recruit top global talent to help more companies scale.
