Cognitive Functions Test
Each of the 32 situations has four answers, so pick the one closest to what you would actually do. It takes about 6 minutes, and the last screen names the Jungian function that leads in your answers and shows all eight scales. The functions here are Jung’s ways of taking in and judging, a different matter from memory or attention.
Extraverted Intuition
Ideas keep branching, and Ne follows each branch out loud.
At work, a meeting about one product turns into talk of three different products, and the talk itself produces the next idea. Plans are drafted quickly and revised just as quickly. A tangent is welcome when it opens another line of thought. Colleagues get pulled in early, because thinking happens in conversation.
New people and new subjects hold attention with little effort. An unfinished thought is shared on purpose, since saying it is how it takes shape, and a colleague's passing remark can become the seed of the next plan. Brainstorming with others is where the thinking gets done.
The cost shows up when a path settles. Once its range is clear, interest cools and the finishing steps wait for the next spark, which leaves a trail of promising starts.
People leading with Ne can pick one option from the ones on the table and stay with it for a full month before looking at another.
Introverted Intuition
For Ni the conclusion comes first, and the reasons follow.
The conclusion shows up as a direction, a sense of where things are heading, and it carries more weight than the data on the table. A plan can feel finished long before anyone writes it down. Trust in the insight runs ahead of the evidence.
Quiet time suits the work. Scattered pieces settle into one view while the mind is busy elsewhere, and attention turns to what that view means for the person and for the people beyond. Long projects with a clear direction suit this work.
Colleagues see the result without the route to it, since the steps behind an insight are hard to retrace. An explanation takes a second pass, and a decision made this way feels settled even when nobody else can see the grounds. Work done alone on a hard problem comes out whole.
The insight goes onto paper in two plain sentences before anyone else hears it.
Extraverted Sensing
Whatever is happening in the room right now has Se's full attention.
Decisions rest on what is in front of the eyes, such as the state of a room or the tone of a voice. Action follows quickly, and plans change on the spot when things turn up. A problem gets solved with whatever is at hand.
In company this shows as presence. Conversation is lively and energy goes into the activity at hand. Hands-on tasks suit this well, and waiting around feels long.
The tangible counts for more than speculation. A claim is believed once it can be seen or touched, and a long discussion of possibilities loses attention to the first practical step.
Thoughts and moods that come from within can feel less real than what arrives through the senses, so quiet reflection has less pull.
A useful rule for this function is to take a ten-minute pause before any large commitment and put the options on paper.
Introverted Sensing
The details of the past stay sharp, and Si reads the present against them.
A date or the arrangement of a room on a given day is held exactly. How a place smelled or sounded comes back intact years later. Names and faces stay attached to the places where they were met.
A new situation gets laid beside an earlier one, and the likeness decides how it is handled. Proven methods carry weight, and a change of procedure is measured against the old one. Routines are kept up with care.
On a team this is the person who knows how it went last time, what was tried and with what result.
An inner impression can outweigh the size of the event, so a small incident that left a strong mark keeps its weight for a long time. Promises are kept the way they were made.
A dated log of what worked sits on the desk, and each finished project adds a line to it.
Extraverted Thinking
A loose situation turns into a plan with goals and rules under Te.
Planning runs backward from the target. Deadlines and budgets come up early, and each task gets an owner. Meetings start on time and end with a decision.
Decisions rest on facts and accepted rules. On a team this brings clear expectations, and a meeting ends with a list of who does what by when. Criteria are set before a choice, so the result can be defended later. A vague request gets turned into a specific one before work starts.
The standard applied to oneself gets applied to others, and a colleague who works differently can look like a problem to fix. Feedback is direct and aimed at the next step. Plans that slip are caught early and reset without drama. Reports are short and lead with the result.
Asking one colleague each week how a rule or deadline looks from their side is a habit that fits Te.
Introverted Thinking
An idea has to hold together internally before Ti accepts it.
Analysis goes deep. A claim gets taken apart until each piece fits with the others, and a gap in the logic shows up quickly, even when nobody else has noticed it. Definitions matter, and a term used loosely draws a correction. Questions are precise.
The result is a private framework, built alone and revised on its own terms. At work it gives a reliable eye for flaws in a plan and a preference for one problem examined thoroughly over a spread of topics touched lightly. Time to think before answering is valued.
Explaining is the harder part. A framework that makes full sense inside is hard to put into words, and colleagues receive conclusions without the structure under them. A talk with one well-informed person suits the work better than a crowded room.
Worth trying: explaining the framework aloud to one listener, using a single concrete example.
Extraverted Feeling
People in the room, and how they are doing, come first for Fe.
A group's mood is read quickly and answered. A tense meeting gets a lighter remark, and small signals such as a pause or a changed tone register at once. Names and birthdays are remembered.
Encouragement and interest in others come naturally, and shared standards act as the guide: what suits the group is what gets done. Harmony between people counts for as much as the task itself. Birthdays and farewells get organized without being asked.
The shared standard can stand in for personal conviction, so a private preference is set aside until someone asks about it. Thanks and praise are given freely, and friction between other people gets smoothed before it grows. A disagreement is raised in a private word.
It can suit Fe to hold one slot a week for deciding something by personal preference alone, before asking what others want.
Introverted Feeling
Fi measures actions and thoughts against values held inside.
Those values may stay unspoken. The outward manner is reserved, while the inner judgment steers what is agreed to and what is declined. Disagreement is felt long before it is voiced, and a request that cuts against a value gets a quiet refusal. A promise made to a friend carries weight for years.
Sensitivity and empathy come with an idealism that keeps an eye on how things could be better. On a team this is the person whose loyalty to a principle holds steady when the group moves on. Others are listened to closely, and the unspoken part of what they say is picked up.
Values left unspoken behind a reserved manner leave colleagues guessing where the line is. A close conversation or a letter is where they finally get said. Time alone restores energy.
A small practice for Fi is naming one value aloud in a conversation each week, in plain words.

About the test
Methodology
Scoring is simple. An answer adds weight to the one scale it points to, and an answer that expresses the center of a function weighs double an answer that shows a side of it. Across the 32 questions each scale gets sixteen chances to collect weight, and the weights are chosen so that two scales cannot finish level. The scale with the highest total is the function that leads, and the result page draws all eight bars as the profile around it. A lower bar means less emphasis in the answers given.
The scales come from Jung's typology, which describes four functions (thinking, feeling, sensing and intuition) and gives each an outward and an inward orientation. That makes eight function-attitudes with a scale apiece. The functions and orientations are Jung's. The label "cognitive functions" and the two-letter codes such as Ne or Fi come from the Myers-Briggs tradition: the first letter marks the function and the second the orientation, and each result carries the name of one scale. The test rests on a person's own answers about themselves. For wider background on typology, see this general reference page.

Frequently asked questions
What is a cognitive functions test?
It is a test built on Jung's idea that the mind works through four functions: thinking and feeling, which judge, and sensing and intuition, which perceive. Each function points outward to people and events or inward to one's own reactions and ideas, so there are eight in all. The word "cognitive" and the short codes come from the Myers-Briggs tradition, while the functions and orientations themselves are Jung's. After the questions, the page names the function that leads in the answers and draws a bar for each of the eight.
What do Ne, Ni, Se, Si, Te, Ti, Fe and Fi stand for?
Each code has two letters. The capital names the function: N for intuition, S for sensing, T for thinking, F for feeling. The small letter gives the direction of attention: e for outward, i for inward. Intuition and sensing take things in, while thinking and feeling judge.
In plain words, Ne spots possibilities and links in the situation at hand; Ni joins images and themes into one new view; Se engages with the concrete present and acts on it; Si compares what is happening with earlier experience; Te organizes things around goals and external rules; Ti tests ideas for internal consistency; Fe looks for harmony with and between people; Fi checks actions against personal values.
Does this test show a function stack?
The result is one leading function together with the profile of the other seven. Each of the eight bars stands on its own scale, and the answer the test gives is a single function, with a type code or a fixed sequence of the rest left out of the picture.
What sets this apart from a four-letter personality test?
A four-letter test sorts a person along four either-or pairs and joins the results into a code. Here each of the eight function-attitudes has a scale of its own, so Extraverted Intuition can sit high or low independently of Introverted Intuition. The result is a function, such as Introverted Feeling (Fi), where a four-letter test returns a code. The two approaches come from different frameworks and answer different questions.
Is the cognitive functions test scientifically validated?
No. The test has not been validated as a measurement instrument; it is a self-report description of eight functions drawn from Jung's typology. The works behind the framework are listed under references.
