Schulte Table Test Online — Free 5×5 Attention & Visual Search Task

In the Schulte table task you find and tap the numbers 1 to 25, shuffled across a 5×5 grid, in ascending order. Cells you have already found are not marked and the next cell is never highlighted, so the visual search itself is what gets measured. Only the number you are currently looking for is shown as text below the grid; tapping any other number is logged as an error and you simply carry on. Five such tables run back to back and each one is timed separately. The whole thing takes about four to five minutes.

The time you need for one table blends several things: how fast your eyes scan for a target, how wide a patch of the grid your attention can take in at once, and how quickly you turn a decision into a tap. The tables are named after the German psychiatrist Walter Schulte, and in Russia and Eastern Europe they have long been used both to look at attention and as material for speed-reading practice. They are known as таблицы Шульте in Russian and 舒尔特方格 in Chinese.

A single table mixes two different things into one number: how quickly you get going, and how fast you actually are. Running five tables in a row separates them, because you can see whether the first table was faster or slower than your average (warm-up) and whether the times creep upwards towards the end (attention stability). The three indices used in Russian experimental-pathopsychology manuals, ЭР (work efficiency), ВР (warm-up) and ПУ (attention stability), are computed from exactly these five times.

The headline score is ЭР (эффективность работы, work efficiency), the mean of your five table times. It is in seconds, so lower is faster, and the result screen shows it as the average per table. It is not a score compared against a standardized norm but simply your own record, so the most accurate reading comes from putting it side by side with a repeat run on the same device at the same time of day.

ВР (степень врабатываемости, the warm-up index) is your first table time divided by ЭР. Below 1.0 means the very first table was already faster than your average, so you get up to speed quickly; above 1.0 means you needed a little run-up before the pace arrived. Think of the first five minutes of an exam or a meeting, where you have to be fast from the start, and the number becomes easy to interpret.

ПУ (психическая устойчивость, the attention-stability index) is your fourth table time divided by ЭР: at or under 1.0 the pace held into the back half, above 1.0 you slowed down as the task went on. Read it together with the line joining your five table times, the fatigue curve, and with the error count. A run with unusually many wrong taps may have traded accuracy for speed, so it is better not to judge from the average alone.

Because you physically tap the cells, screen size and input method (finger or mouse) can shift the same person by several seconds per table. Short sleep, caffeine, the time of day and background noise show up in a single table time as well. So if you want to track a trend, the most important thing is to repeat the test without changing the device or the conditions.

Absolute seconds vary so much with device and age that they are hard to compare with other people, but ВР, ПУ and the shape of your table-by-table curve survive a change of device reasonably well. Note too that with repetition you pick up the knack of keeping your gaze in the middle of the grid and scanning outwards, so times tend to fall: a record after many runs mixes any change in attention with a straightforward practice effect.

Using it is simple. Run it every so often at the same time of day to build a trend, and compare conditions on purpose: a well-slept day against a short-sleep one, before a study block against two hours into it. Five tables take only about five minutes, which also makes it a decent warm-up before work that needs concentration. This is Soundary's own self-check and it does not replace a professional judgement; if your attention keeps slipping enough to disturb daily life, take your records and talk it over with a qualified professional.
