Processing Speed
Neuro-SensomotoricLearn a digit–symbol key, then match a rapid stream of symbols to their digits as fast as you can. Pure coding speed against the clock.
Overview
Processing speed is the rate at which you can carry out simple, over-learned perceptual-motor operations — take in a stimulus, apply a fixed rule, and produce a response — over and over, quickly and accurately. It is measured separately from reasoning and knowledge because how fast you execute trivial cognitive work is its own capacity, and one that is unusually sensitive to fatigue and mental workload. This test uses the classic Digit-Symbol Coding paradigm: a fixed key maps nine symbols to the digits 1–9, and you work through a rapid stream of symbols, giving each one's digit as fast as you can before the clock runs out — so your result reflects both throughput and accuracy. The format follows the WAIS Digit Symbol Coding subtest and its symbol→digit twin, the Symbol Digit Modalities Test, and mirrors the CogScreen and DLR-style processing-speed modules used in pilot and aeromedical selection. Processing speed of exactly this kind underpins cockpit workload — scanning instruments and translating them into control inputs quickly and reliably.

Example: code the symbol
A key pairs each symbol with a digit and stays on screen the whole run. Each item shows one symbol — read the key and enter its matching digit as fast as you can. Here is a small key with one item worked through.
Game Phases
Configure
Pick a test length. Longer tests give you more items to clear and a higher target of net-correct answers.
Read the Key
A key pairing nine symbols with the digits 1–9 stays on screen the whole run. Glance at it whenever you need to.
Code Fast
A symbol appears — enter its digit with the keypad or the keyboard number keys. The next symbol appears instantly; keep the stream flowing.
Review
See your accuracy, your speed in items per minute, an item-by-item map and every mistake you made.
More Practice
Reaction & Attention
19 exercisesComplex Choice Reaction Test
Compare a target figure against four reference shapes and decide within 2.5 seconds whether it matches one of them.
Vigilance Test (VIGIL)
Test your attention and reaction speed. Detect when the moving circle skips a position.
Determination Test (DT)
Test your reaction speed with colors, directional arrows, and sounds across adaptive difficulty levels.
Instrument Monitoring Test
Watch a bank of cockpit gauges and catch the moment any needle drifts out of its green band — before the response window closes.
Perceptual Speed
Compare two strings at a glance and decide — same or different? Rapid-fire detail checking against the clock.
Simple Reaction Time
A single signal appears after an unpredictable delay — respond as fast as you can. Measures your mean reaction time, your fastest response, and how consistent you are. Includes a Pair Match mode in the format of cut-e's Reaction Speed test: press only when two symbols match.
Stroop Test
Name the ink colour, not the word. A colour word streams on screen in a possibly-mismatched ink — select the ink colour and resist reading the word.
Visual Scanning
Sweep a cluttered field and connect the numbers in order — 1, 2, 3 … — as fast as you can find them.
Attention Switching
Connect scattered numbers and letters in alternating order — 1, A, 2, B, 3, C … — switching mental tracks on every single step.
Auditory Detection Test
Monitor a spoken number stream in your headphones and respond only to the targets — or to the hidden even/odd runs.
Time Anticipation Test
A green ball flies at constant speed, then vanishes before a marked line. Press at the exact moment it would cross — then point to where. Timing error in milliseconds, position error in pixels, in the style of Schuhfried's ZBA.
Signal Detection Test
Watch a dark field of about 25 small white dots that appear and disappear at random, and press the moment four of them form a square. A practice version of SIGNAL, Schuhfried's signal-detection vigilance test in the Vienna Test System, with the S1 white-on-black and S2 black-on-white forms and a sudden-death Challenge mode.
Monitoring Ability Test
Count the blue dots drifting inside a circle and pick the exact number from five buttons before the clock runs out. A faithful practice version of scales cmo, cut-e's name for this test, also called the CUT-E Monitoring Ability Test.
ENAC Symbol Counting
Two counting exercises, and every board gets interrupted twice by a grid of colour words. In Attention 2 you count one symbol among two others that look a lot like it. In Attention 3 you count the x signs, minus after a / and plus again after a +. Each grid stays open for 12 seconds. In Attention 2 you tick the words written in their own colour, and in Attention 3 the ones that aren't. The exam format is 10 boards of each, 90 seconds a board.
ENAC Sustained Attention
You see four characters in four places: NW, NE, SW and SE. Then each board shows four grids of characters, one in each place, and for each place you say whether its own character is in its grid. The grids are built from those same four characters, so only the one that belongs to the place counts. The exam format is 3 series of 5 boards, with 3 minutes for each series.
ENAC Dials Reading
Eight car and aircraft dials, with a table underneath that has a column for each of their ten readings. Tick the value each dial shows. You get to study the dials before the clock starts, and they stay put for the whole run. The exam format is 10 boards in 6 minutes.
ENAC Odd and Even
A board of numbered circles, scattered over the whole screen. Starting from START, click every one, odd and even in turn, with the odd numbers in ascending order and the even ones in ascending order, each on its own. A wrong click sends you back to START. The exam format is 5 boards with 90 seconds each.
ENAC Shapes and Colours
One shape at a time, filled or empty, in one of two colours. Two rules tell you whether to press X or N, and the colour says which rule to use. Each shape shows for half a second, and the exam format is 32 shapes, one every 3.2 seconds.
ENAC Mosaic Count
A black figure made of 16 tiles in a 4 × 4 square, with no lines between them. Count how many there are of each of the ten kinds and type each count under its tile, with a 0 for every kind that isn’t there. The exam format is 24 boards in 10 minutes.
