Mental age: when your behavior seems younger than your actual years, or when you appear so composed that it feels like you’ve lived several lifetimes.

How big is the gap? A psychological test that reveals your mental age (1–10)
A psychology test that reveals your mental age based on what was in the drawer

This is a psychological test that diagnoses your mental age based on what would surprise you if you found it in your school desk.
Imagine you’re back in middle school and choose from four options: a 10,000-yen bill, a razor, a dead insect, or a photo of someone you like.
Depending on your choice, your mental age will be diagnosed as either 5–15, 20–30, 40–50, or 60 and over.
It also reveals how you perceive things, so why not give it a try as a reference?
A psychological test that reveals your mental age based on what you see

This is a psychological test that reveals your mental age based on your intuitive answer to what the illustration looks like.
From the four options—campfire flames, a stylish dessert, a parent and child bird, or a foreign-style hat—your mental age will be diagnosed as 17, 22, 33, or 59.
Advice is provided for each result, but since mental age is not visible, consider using it as a reference if anything resonates or feels accurate.
It’s simple and makes for a fun activity that livens up gatherings with large groups.
A psychological test that reveals your mental age based on which of the four doors you choose

This is a personality test that reveals your mental age based on which of the four doors in front of you you choose.
The four options—a door leading into a forest surrounded by trees, a door opening to a futuristic city bathed in purple light, a door illustrated with an old map and compass for exploration, and a door adorned with musical notes and instruments—all seem appealing, don’t they? Depending on your answer, your mental age will be diagnosed as 10, 25, 30, or 50, and the positive aspects of each will be presented as your result.
Why not give it a try?
A psychological test that reveals your mental age in 10 questions

This is a psychological test that determines your mental age based on 10 questions and the total points from your answers.
Each of the 10 questions has a theme: color, movies, food, the internet, sense of responsibility, vacations, a large sum of money, skill development, power animal, and philosophy.
Depending on the total score corresponding to all your answers, the result will indicate a mental age of 9, 15–24, 25–34, 35–44, or 50 and above.
Because the outcome is derived from answers across various categories, it can also be fun to try again after some time has passed and your preferences have changed.
A psychological test that determines your mental age based on the answers to three questions

This is a psychological test that can determine your mental age by answering three questions.
Each question has four choices with assigned points, and after finishing all three questions, you add up your points to get your result.
If you try it with a large group, it’s best to have each participant calculate and remember their own score or jot it down on paper.
Based on the total score, you’ll get a result indicating your mental age as being in your teens, 20s, 30s, or 40s and above.
Give it a try!
A psychological test that reveals your mental age based on which illustration catches your attention

This is a psychological test that determines your mental age based on which of the four presented illustrations catches your attention.
Depending on your choice—walk, candy, computer, or music—the result will indicate whether your mental age is that of a child, youth, adult, or elderly person.
It might work better as a psychological test if you choose intuitively by looking at the illustration itself rather than interpreting its meaning.
Since it can be done quickly, it’s an easy test to try when you’re hanging out with friends.
A psychology test that reveals your mental age by how you give something to a friend

This is a psychological test that reveals your mental age based on the decision you make when a friend insists on having a treasured possession that you value.
Choose one of the four options: you’d give it to them if they’re an important friend, you’d give it if they pay the full price, you’d give it if they ask while crying, or absolutely not.
All are easy-to-picture choices, but the one you pick will diagnose your mental age as 8, 20, 30, or 40.
Since it reflects your way of thinking and level of maturity, it’s a psychological test we’d love for many different people to try.
