What Is the Attention and Focus Test?
The Attention and Focus Test on ReflexBenchmark is a three-round star-counting challenge. You watch a stream of symbols appear one at a time and try to remember how many stars (⭐) you saw. Other symbols appear as distractors, but only stars count. Once a round ends, you enter your count. The page then compares your answer with the number of stars shown in that round.
This is not a traditional reaction time test. You do not need to click when a star appears. Instead, the challenge is to track a running count while several different shapes pass by. You must recognize the target, ignore irrelevant symbols, and keep the count in mind until the stream finishes. The game makes this more demanding by presenting symbols faster in the second and third rounds.
The result describes your performance on this specific browser activity. It is useful for repeatable practice and comparing your own attempts under similar conditions, but it is not a clinical test of attention span, an ADHD screening tool, or a general measurement of intelligence.
How to Play the Three-Round Star Counting Game
- Press Start Test and focus on the symbol display. The first stream begins automatically.
- Count each ⭐ star as it appears. Do not count moons, circles, triangles, flowers or any other distractor.
- When the stream ends, the display changes to a question mark. Enter the number of stars you remember seeing, then press Submit count.
- Review the feedback showing the actual number of stars. The next stream begins after a brief transition.
- Complete all three rounds to see the saved-score status, round-by-round accuracy bars, total count error and median answer time.
You do not need to memorize the order of every symbol, just the number of target stars. If you lose track, make your best estimate rather than pressing random buttons during the stream; the answer field only appears when the round has finished. Enter a whole number between 0 and 50. A new attempt starts fresh, so do not expect the same target counts each time.
Keep the tab visible. If you switch away while the game is active, the attempt is interrupted and no incomplete result is submitted. This prevents a partly viewed stream from being treated as a normal completed session.
How the Three Rounds Become More Difficult
The test uses a fixed three-round structure, but the actual star count and distractor sequence are randomized for each session. The first round shows 24 symbols at approximately 550 milliseconds per symbol, with 5–8 stars. The second round shows 30 symbols at approximately 450 milliseconds each, with 7–10 stars. The third round shows 36 symbols at approximately 400 milliseconds each, with 9–12 stars.
More items and shorter display times leave less opportunity to recover after a missed star or an accidental double count. The rising challenge comes from the pacing and number of items, not from switching to a different target symbol. The task remains the same throughout: count stars, ignore distractors, and report the count after each stream.
How Your Attention Score Is Calculated
Each round begins with a score of 100 points. The game subtracts 10 points for every star by which your answer differs from the actual count, with a minimum round score of zero. An answer that matches exactly gets 100 points. Being off by one star gives 90; being off by two gives 80. Overcounting and undercounting by the same amount have the same scoring effect.
Your final attention score is the average of the three round scores, rounded to the nearest whole number. It is displayed as a percentage-style training score from 0% to 100%. That percentage is the game's own count-accuracy scale: it is not the percentage of all symbols identified correctly and should not be interpreted as a clinical attention percentile.
Worked Score Example
Imagine that Round 1 showed 7 stars and you answered 7: your error is 0, so your score is 100. Round 2 showed 10 stars and you answered 8: your error is 2, so your score is 80. Round 3 showed 9 stars and you answered 10: your error is 1, so your score is 90.
The final score is (100 + 80 + 90) ÷ 3 = 90%. The total count error is 0 + 2 + 1 = 3 stars, and the number of exact counts is 1 out of 3. These example values illustrate the formula; they are not an average or benchmark for other players.
A key detail is that the final percentage rewards accurate counting, not fast typing. The game records how long it takes to enter the answer after each stream, but that answer time does not directly change the percentage score. You can therefore have a high accuracy score with a relatively long answer time, or answer very quickly and lose points through counting errors.
How to Read Your Result and Real Accuracy Graph
The result screen shows your final score and three additional statistics. Exact counts tells you how many rounds you answered perfectly, from 0/3 to 3/3. Total count error adds the absolute number of stars you missed or overcounted across all rounds. Median answer time is the middle of your three response times after the symbol streams ended, displayed in seconds.
The graph contains three real bars, one per round. Each bar shows that round's score from 0% to 100%, not the number of distractors or the total session time. A fully accurate round reaches 100%. A lower bar means your count differed from the actual target count by more stars. The details panel below the graph lists the true count, your answer, their difference, the round score, and the recorded time taken to submit that answer.
When a completed attempt is accepted by the score-saving API, the site can record your result. An attempt ranking appears only when there are enough comparable previous website attempts; otherwise you will see a pending status. This comparison concerns recorded website attempts, not a representative age group or a medically established norm.
What Skills Are Involved in This Counting Challenge?
Selective attention means choosing which information matters for the current task. Here, a star matters and the surrounding set of distractor shapes does not. Sustained focus is needed to continue applying that rule from the first symbol to the last. You also need a small amount of working memory to keep a running count and update it whenever another star appears.
The star-counting format also differs from tests that require an immediate button press to every target. In a Go/No-Go task you decide whether to respond to a stimulus. In a Stroop task you select an ink color while ignoring conflicting word information. This attention test instead asks you to monitor a stream and report its total at the end.
Practical Tips for More Consistent Results
- Choose a quiet moment. If you want to compare multiple sessions, reduce notifications and avoid talking while the streams are playing.
- Keep your gaze on the display. A brief look away can cause a missed target, especially in the faster rounds.
- Count stars only. Do not try to memorize all of the symbols. A simple mental count is enough for this particular task.
- Use a steady counting rhythm. Add one only when a star appears; resist restarting the count after a distracting shape.
- Compare attempts on the same device. Device and browser conditions can change the experience of the timed streams.
- Review the three bars. Notice whether you repeatedly lose accuracy in one round rather than just chasing a higher final percentage.
- Pause between attempts. Taking a break can help you avoid confusing fatigue or frustration with a change in your usual performance.
Practice may make you more familiar with this exact exercise and help you develop a counting strategy. It should not be presented as proof that a few sessions improve school performance, attention at work, or a diagnosed attention condition. Track your own results over time and use the numbers for a modest, task-specific comparison.
Accuracy, Device Effects and Important Limitations
ReflexBenchmark runs the display and timer in an ordinary browser. The length of each symbol's appearance is requested through software rather than controlled by specialized measurement equipment. Screen behavior, background load and the moment an answer is entered may differ from one device to another. Switching tabs interrupts the exercise, but staying on the page does not guarantee identical visual presentation across hardware.
The score-saving system can check that submitted target counts fall within the allowed ranges, that there are three answers, and that the submitted score follows the game's calculation. However, because the symbol sequences are generated in the browser, server-side checks do not independently prove the precise sequence a person saw, whether the timing was laboratory-accurate or whether the activity was completed unaided. A saved score is a recorded game attempt, not independent proof of human attention.
Use this as an informal focus and counting exercise. It is not a diagnostic screening, a standardized attention-span assessment, a measure of neurological health or a substitute for professional evaluation. If you have concerns about your attention in everyday life, those cannot be answered by a three-round website score alone.
