Cognitive Functions Test
This free cognitive functions test asks you to rate 48 statements, six for each of the eight Jungian functions, and takes about 6 to 8 minutes. You get a 0 to 100% score for Ni, Ne, Si, Se, Ti, Te, Fi, and Fe, your likely dominant and auxiliary pair, and the four-letter type whose function stack your results most resemble.

What a cognitive functions test measures
Cognitive functions are the building blocks behind four-letter personality types. Instead of four either-or preferences, they describe eight mental processes: four ways of taking in information (sensing and intuition, each pointed inward or outward) and four ways of deciding (thinking and feeling, each pointed inward or outward).
Each of the eight has its own page on this site. In brief: Ni converges on meaning, Ne branches into possibilities, Si draws on past experience, Se engages the present moment, Ti builds inner logic, Te organizes outer results, Fi follows personal values, and Fe tunes into group harmony.
Where the idea comes from
The concept starts with Carl Jung's book Psychological Types, published in 1921. Jung described introversion and extraversion as attitudes and paired them with four functions, sensing, intuition, thinking, and feeling, producing eight function-attitudes.
Later type theorists built on that work. They proposed that each person has a preferred order of functions, often called a function stack, with a dominant function leading, an auxiliary function supporting it, and a less developed inferior function at the bottom. That stack model is what links the eight functions to the familiar four-letter type codes.
How the test and scoring work
The Jungian cognitive functions test has 48 statements written for Traitprint, six per function. For each, you choose a point on a 5-point scale from strongly disagree to strongly agree. Your six answers for each function are combined and converted to a score from 0 to 100%.
We then look at your highest-scoring functions to suggest a likely dominant and auxiliary pair. Because a valid stack pairs a perceiving function with a judging function and an introverted with an extraverted one, we match your pattern to the four-letter type whose standard stack it most closely resembles.
How to read your results
Treat the eight scores as a profile of your habits, not a verdict. A high score means you described yourself as using that mental process often and comfortably; a low score means it is less familiar territory. Scores that sit close together suggest you use those functions in a similar measure, and in that case the suggested type is a looser match.
If the suggested pair surprises you, read the pages for your top three or four functions and ask which description fits how you act when no one is watching and nothing is at stake.
Honest limits
This cognitive function test is a self-report tool, so it reflects how you see yourself on the day you take it. Mood, context, and how you interpret a statement can all shift results, and people often score the functions they admire higher than the ones they actually use.
It is also worth being clear that typology is not settled science. Academic personality psychology generally favors trait models such as the Big Five, and the function-stack idea has limited research support. Use your results for reflection and conversation, never for diagnosis, hiring, or other high-stakes decisions.
FAQ
Is this an MBTI test?
No. Myers-Briggs Type Indicator® and MBTI® are trademarks of The Myers-Briggs Company. Traitprint is independent and not affiliated with, endorsed by, or connected to that company or its assessment. We use Carl Jung's public function concepts and wrote our own statements and scoring from scratch.
How long does the cognitive functions test take?
Most people finish the 48 statements in 6 to 8 minutes. There are no right or wrong answers, and going with your first instinct usually gives a clearer picture than overthinking each one. You can retake it whenever you like to see how stable your results are.
What is the difference between a dominant and an auxiliary function?
In the function-stack model, the dominant function is your most natural, trusted mental process, the one you lean on by default. The auxiliary function supports it and balances it, so if your dominant function takes in information, your auxiliary one helps you make decisions, and the reverse.
Why doesn't my result match the type I got elsewhere?
Different tests use different statements, scoring rules, and theories, so mismatches are common. Four-letter tests measure preferences directly, while a function test infers type from your function scores. If two results disagree, read both descriptions and decide which fits your everyday behavior better.
Can my cognitive functions change over time?
Type theory usually holds that your core preference stays fairly stable, but how well you use each function can grow. Many people find their less developed functions become more comfortable with age, practice, and new responsibilities, which can shift scores between attempts.
Is the test free?
Yes. The test, your eight function scores, your suggested dominant and auxiliary pair, and every function page are free to use.
