Mental Age Test

This Mental Age Test is originally from Japan, where it’s named 精神年齢チェック. For over 10 years, we've fine-tuned this quiz using user feedback and scientific research to make it as accurate as possible for you. Please answer every question honestly. Nobody will see your answers.

The result has nothing to do with your IQ. For the purpose of this test, we define Mental Age as a measure of a person’s psychological abilities in comparison to the number of years it takes for an average child to reach the same level. For example, if your mental age is 10, regardless of your actual chronological age, you are mentally similar to a 10-year-old.

Frequently Asked Questions

Can you give more background to this Mental Age Test?

Good question. Our Mental Age Test was first released in November 2013 on my personal website. The original concept was introduced to me by a friend from Japan, but at the time, I couldn’t find any online version of it. It quickly became a viral hit and has now been translated into 32 languages, making it one of the most shared pages on Facebook and Twitter. We're proud that many famous people have taken the test and that, according to Google Analytics, over 150,000,000 people from more than 239 countries and regions have participated! (as of May 25, 2025)

In February 2014, I created the domain arealme.com specifically for this quiz and others like it, making the Mental Age Test the very first one on our new site. Since its launch, we have been committed to making the test better and more accurate. To do this, we've continuously updated it by listening carefully to user feedback from social media and our comments section. Alongside that, we also refer to scientific papers and academic research to ensure our questions and scoring algorithm are as reliable and well-grounded as possible.

Other fun facts about our Mental Age Test

  • In 2013, test takers were required to enter their actual age before beginning the test. The average age of participants was 23.
  • In 2014, due to privacy concerns, we allowed test takers to opt out of providing their actual age. The average age of participants then dropped to 16, suggesting that individuals under 18 are less concerned about disclosing their real age.
  • Question #3 is: “I spend most of my time on ___________”. We included a textfield for users to input their own responses. The most frequently mentioned activities are:

In academic terms, what is Mental Age, and why is it worth knowing about?

Mental age is a concept originally used in psychology to describe how a person’s intellectual performance compares to the average performance of people in different age groups. For example, if a 10-year-old performs at the level of the average 12-year-old on a cognitive test, their mental age would be 12. While this idea came from early intelligence testing, it still serves as a fun and meaningful way to explore how we think, feel, and make decisions—regardless of our actual age.

Here at arealme.com, our Mental Age Test is designed to be enjoyable and lighthearted, but it’s not random. In fact, we’ve integrated a variety of scientific insights from psychology and cognitive science to make the test as accurate and meaningful as possible. Since we first launched the quiz, we’ve continued to update and improve it based on new ideas and user feedback. The result? A quiz that blends fun with surprising depth.

🧠 Mental Age and your brain:

So what does science say about mental age and how our brains change over time?

Research shows that certain mental abilities—like memory, attention, and problem-solving—tend to evolve as we grow older. Some abilities, such as vocabulary and general knowledge, often improve or stay stable. Others, especially processing speed and working memory, tend to decline slightly starting in adulthood. Learn more from this study: Wu et al. (2023) – A systematic review on exercise and cognitive training effects on working memory in older adults.

However, mental decline is not inevitable. Studies show that cognitive training—things like memory exercises, attention games, and problem-solving challenges—can help improve mental performance. Some research even shows that these activities increase blood flow in the brain, especially in areas responsible for focus and planning. Learn more here: Mozolic et al. (2010) – Cognitive training intervention and cerebral blood flow in older adults.

Other factors—like regular physical activity, curiosity, and lifelong learning—can also keep our minds sharp and youthful.

That’s why our Mental Age Test isn’t just a fun way to pass time—it’s also a reflection of real psychological concepts like executive function, emotional maturity, and decision-making. Behind every question is a carefully considered idea drawn from research in human development, cognitive psychology, and behavioral science.

❗ Bottom line:

Your mental age isn’t just a number. It’s a snapshot of how your brain works—how you approach the world, solve problems, and understand yourself. Whether you score younger or older than your actual age, the important part is learning more about how your mind works—and having some fun along the way.
