Deputy Editor of RAG MUSIC. JFC-certified fact-checker. I’m Sasashina, a mom currently raising an elementary schooler and a preschooler. During my student years at Kyoto College of Science and Technology, I studied a wide range of fields including sound, lighting, and video technology, building a foundation in comprehensive stage production and creative expression. After graduation, I joined a music production company, where I still work, consistently building experience in production and engaging in a variety of music-centered tasks. Currently, I mainly handle articles for children, drawing on what I’ve learned about parenting and what I feel and discover through daily interactions with my kids. I hope my work can be of help to you, even in a small way!

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.

Because we act based on our past experiences, it’s hard to notice our own mental age—but aren’t you curious how others see you?

With that in mind, here are some psychological tests that can reveal your mental age.

We’ve compiled a wide range—from simple ones to those with many questions—so why not use them as a tool for self-reflection?

A personality test that reveals your mental age with 15 color-related questions

This is a psychological test that determines your mental age through 15 color-related questions.

Each question has four options; choose the one that best matches your impression.

Each choice has an assigned score, and the total of all 15 determines your category: under 18, 18–24, 25–45, or over 45.

Because color is an abstract criterion influenced by preferences, knowledge, and the subconscious, trying it with a large group can yield a variety of answers and make it more enjoyable.
