Cognitive Function Test: See Your Scores Across Five Everyday Thinking Skills
This Cognitive Function Test explores reported memory, attention, word-finding, planning, and speed difficulties. Original, unvalidated questions give an instant breakdown and optional PDF, not a dementia diagnosis.
Reviewed by Michael Callans, MSW 
Cognitive Function Test is a free, confidential 25-question self-assessment, original items informed by cognitive-lapse research. It takes about 7 minutes, runs entirely in your browser, and gives you a plain-language score across 4 interpretation bands plus an optional in-depth report. It is an educational screening, not a diagnosis.
What this assessment explores
Cognitive function includes remembering, paying attention, using language, planning, and processing information. This is a cognitive functions test for everyday thinking lapses, not the Jungian cognitive functions personality typology. This self-assessment helps you describe everyday difficulties and prepare examples for a healthcare professional; it does not directly measure these abilities.
Separate areas of everyday thinking
Five original statements cover each domain so memory does not dominate the result. The breakdown can highlight where you notice difficulty, such as keeping attention on a task versus retrieving a familiar word. These are our own descriptive groupings, not validated CFQ subscales or separate ability tests.
Lapses in recognizable situations
The questions ask about ordinary activities over the past month. They do not ask you to perform timed tasks or remember a word list. That makes this a record of your experience, with the strengths and limits of self-report, rather than a disguised intelligence or dementia test.
Change and functioning come first
The result explains why recent change, safety, and effects on daily life matter more than a total. It includes clear guidance for sudden confusion and persistent concerns, and links to narrower educational pages when you need more specific language for an appointment.
| Feature | Typical free quiz | Psychology.com |
|---|---|---|
| What is assessed | May blur self-report with performance testing | Your reported frequency of everyday lapses |
| Domain coverage | May focus mainly on memory | Five items in each of five domains |
| Subscale status | Source of groupings may be unclear | Our own unvalidated groupings, not CFQ factors |
| Ability claims | May offer a brain age or intelligence estimate | No brain age, IQ, or ability estimate |
| Dementia claims | Some pages suggest online detection | Cannot detect or rule out dementia |
| Next steps | May focus on training games | Medical review for persistent change; urgent help for sudden confusion |
How scoring works
Answers are scored 0–100 in total. Your result falls into one of 4 bands:
| Score | Band | What it suggests |
|---|---|---|
| 0–25 | Fewer lapses reported | You reported relatively few of these experiences. Recent changes and everyday functioning still matter more than the total. |
| 26–50 | Some recurring lapses | You noticed several everyday difficulties. Identify when they occur and whether they represent a change for you. |
| 51–75 | Frequent lapses reported | These difficulties appear frequent in your answers. A medical conversation is appropriate, particularly if daily tasks have become harder. |
| 76–100 | Very frequent lapses reported | You reported difficulty across much of this questionnaire. Prioritize a medical assessment and practical support for daily responsibilities. |
What can make your score go up or down besides your memory
The Cognitive Function Test records how you describe everyday thinking difficulties. Poor sleep, high stress, unfamiliar routines, or a distracting life event may be relevant context when you discuss those difficulties with a clinician. This original questionnaire has not been studied to establish how much any of these circumstances changes a score. A calmer month may feel different, but a lower result cannot establish that the cause of a concern has resolved.
A score on its own cannot explain why lapses occur. If you repeat this reflection, consider whether your responsibilities and opportunities to notice difficulties have changed. A Stress Diary kept alongside concrete examples can help organize what was happening when problems appeared. The comparison describes your experience; it cannot distinguish stress from a medical cause or prove that thinking ability has improved.
Who this reflection is useful for
This page suits an adult who has noticed a change, however small, in day-to-day thinking and wants plain language to describe it, whether that is to themselves, a partner, or a clinician. It also suits someone who feels generally sharp but wants a structured way to check whether attention, word-finding, planning, or speed stands out as an area worth watching.
It is not built for children, and it is not a substitute for a workplace performance review, a school evaluation, or an IQ estimate. If your goal is understanding intelligence or academic ability rather than everyday functioning, this is the wrong tool for that question. If your concern is specifically about a loved one's memory rather than your own, the Memory & Dementia Concern Screen is written for that situation instead.
If putting your experience into words for a professional feels daunting, that conversation does not have to start with a diagnosis question. You can search the Psychology.com therapist directory for someone who works with cognitive or health-related concerns and simply describe what you have noticed.
For a related topic in the Psychology.com tests hub, the Brain Fog Test explores mental cloudiness and the Executive Function Test focuses on organizing and completing tasks. Choose the page that matches the concern you want to describe. Completing more questionnaires is not required before you ask for help.
How to prepare for a cognitive assessment
Bring examples that show a change from your usual functioning, such as missing familiar steps while cooking or losing track of bills you previously managed comfortably. Write down when the change began, whether it is getting worse, and what help you now need. Include current medicines and supplements, and ask someone you trust to share observations if you would find that useful.
Tell the clinician about difficulties even if your online result looks reassuring. Ask what a formal assessment would investigate and how the findings would guide care. If confusion starts suddenly, seek urgent medical help rather than waiting for an appointment or completing another questionnaire.
Methodology & sources
This original questionnaire is informed by the study of everyday cognitive failures, including Broadbent and colleagues’ Cognitive Failures Questionnaire (CFQ), published in 1982. The CFQ concerns self-reported lapses; we have not copied its items or administered it here. The original CFQ contains 25 items rated on the same 0 to 4 frequency scale we use here, which is part of why our questionnaire matches its length and format even though the wording and domains are our own. Our 25 original statements use a past-month timeframe and a 0 to 4 frequency scale, with no reversed items. Five items belong to each of our own descriptive domains: memory, attention, language/word-finding, executive function, and processing speed. Each domain ranges from 0 to 20, and the total ranges from 0 to 100. These five domains are not the CFQ’s validated subscales, and their apparent separation should not be mistaken for proof that different brain systems have been measured.
This exact questionnaire is unvalidated. Total-score bands of 0 to 25, 26 to 50, 51 to 75, and 76 to 100 are educational divisions, not clinical cutoffs, age norms, or probabilities of illness. Higher scores mean more reported difficulty, not lower measured ability. Self-awareness, the tasks you encounter, language, sleep, health, and current circumstances can influence responses. This is not the MoCA, MMSE, or SLUMS, which are clinician-administered assessments, and it cannot detect or rule out dementia. The related /tests/memory-screen and /tests/dementia pages also require cautious interpretation. New or worsening difficulties deserve medical attention regardless of score; sudden confusion requires urgent assessment rather than finishing this questionnaire.

Cognitive Function Test FAQ
Is this a cognitive ability test?
No. It is a self-report about how often you notice everyday lapses. It does not time your thinking, test recall under controlled conditions, or measure intelligence. Someone who notices many mistakes can still perform well on formal tasks, and someone who reports few concerns can still need assessment. Use it to describe your experience, not to certify your abilities.
Can this detect dementia or replace the MoCA, MMSE, or SLUMS?
No. This is not the MoCA, MMSE, or SLUMS; those are clinician-administered assessments with specific procedures. This questionnaire cannot detect or rule out dementia. The memory concern screen and dementia concern test offer additional educational reflection, but persistent or progressive change should be assessed medically.
How does this differ from brain fog or executive function tests?
This page covers five broad areas equally. The brain fog test focuses on the experience of mental cloudiness, while the executive function test explores managing tasks in more detail. These concepts overlap, and taking several questionnaires cannot identify the cause of a difficulty.
What if a statement does not fit my usual activities?
Think of the closest comparable activity you actually do. If there is no reasonable example, do not invent a lapse or assume that absence of opportunity proves intact functioning. You can stop and describe the concern directly to a clinician. The engine requires every answer to produce a score and has no separate not-applicable adjustment, which limits comparisons between people.
When should I seek help instead of taking a test?
Seek urgent medical help for sudden confusion, especially with new trouble speaking, weakness, severe headache, or a marked change in alertness. Do not drive yourself. For gradual concerns, arrange medical review when thinking difficulties are new, worsening, or interfering with ordinary responsibilities. A reassuring questionnaire result should not delay that conversation.
Is it free, and what happens to my information?
The questions and on-screen results are free, with no account or email needed. Scoring happens in your browser. The supplied engine keeps answers in this tab’s session storage and records usage events. If you request a PDF by email or buy a report, summary scores are sent for that service; individual item answers are not sent by those flows. Use a private device if others can access your browser.
