Attention & focus tests
Game-like brain tests — attention, memory, speed and executive function.

Everyday Focus Obstacles
Nine questions on interruptions, planning and recovery. A daily-life check, not a diagnosis.
Stroop test
Inhibition under color-word interference.
Emotional Stroop
How much emotional words capture attention — where mood meets focus.
Selective attention
Pick targets out of distractors.
Go/No-Go
Sustain attention while inhibiting impulses.
Flanker task
Focus on the center, ignore the flankers.
Object tracking
Track the targets among moving dots.
Simon task
Respond to color, resist the location pull.
Attention cueing
How fast does your attention spotlight move?
Visual search
Does more clutter slow you down? Search slopes.
Mind-wandering (SART)
How often does your mind drift under monotony?
Attentional blink
Catch the half-second your brain blinks.
Change blindness
Spot what changes between the flickers.
Auditory CPT
Tell high from low tones by ear and respond only to targets — auditory sustained attention.
Subitizing
When dots flash for 0.18 seconds and vanish, can you tell how many without counting? This test finds where your instant number sense — the subitizing range that just 'pops out' at 1–4 items — gives way to slow, one-by-one counting, revealing your perceptual speed.
Schulte tables
Find the scrambled numbers 1–25 in order on a 5×5 grid, then do it again across five tables in a row. The average of the five times gives your work efficiency, while the first and fourth tables show how quickly you get up to speed and whether your attention holds to the end.
Memory10
N-back (2-back)
Working-memory updating.
Digit span
Short-term memory span for digits.
Spatial span (Corsi)
Spatial working memory for locations.
Chimp test
Can you beat a chimp? Flash number memory.
Pattern memory
Recreate the flashed tile pattern.
Word memory
Seen it before, or new? Keep the streak.
Visual WM (change detection)
Did the colors change? Measure your capacity K.
Paired associates
What was where? Object-location memory.
Token search
Search every box — never the same one twice.
Sternberg Memory Scan
Memorize 1–6 digits, then instantly judge whether a probe digit was in the set. Beyond accuracy and reaction time, it measures how much each extra item slows your decision (ms/item) — revealing the speed and efficiency of your memory scanning.
Processing speed4
Executive & decision13
Task switching
Flexibly switch when the rule changes.
Mental rotation
Same shape or mirrored? Rotate it in your head.
Stop signal
Your brain's braking distance (SSRT).
Tower planning
Plan the minimum moves to build the tower.
Rule discovery
Crack the hidden sorting rule as it shifts.
Time sense
Stop at exactly 10 seconds. Test your inner clock.
Balloon risk
Pump for points — but don't pop it!
Anti-tap
Resist the reflex — tap the opposite side.
Clock Drawing Test
A computerized CDT: place the numbers on a blank clock face and set the hands to 11:10 — auto-scored.
Card Sorting Test
Discover the hidden sorting rule from feedback and shift when it changes — a rule-shifting executive function task.
Verbal Fluency
Two 60-second rounds — type as many animals and F-words as you can.
Card Deck Choice Task
Pick one of four card decks to win money. Some pay big rewards but even bigger penalties (a long-run loss); others pay small but come out ahead. The rules stay hidden, so you learn the winning decks by feel as you take penalties. It reveals how you decide under uncertainty — resisting tempting rewards now for a better long-term payoff.
Delay Discounting
Choose again and again between a smaller reward now and a larger one later — revealing how well you wait for the future, your impulsivity and self-control.
