About this area

Sharpen selective attention, inhibitory control, and vigilance. Filter distractions and stay on target for longer.

Each exercise targets a narrow construct: working memory, selective attention, processing speed, inhibition, mental rotation. You get a clean measurement every session.

Train mode gives you immediate feedback and adaptive difficulty so you learn fast. Test mode is timed and scored so you can benchmark against yourself over weeks.

Each exercise here is scored so you see your real progress, not vague points. Train mode gives immediate feedback. Test mode is timed and comparable to your past sessions.

The science

Each test is constructed using Item Response Theory (IRT) and Classical Test Theory (CTT) to ensure reliable measurement of knowledge and ability across different difficulty levels.

Questions undergo rigorous review including difficulty calibration, discrimination analysis, and distractor effectiveness evaluation to maintain high assessment quality.

Meta-analyses show attention training transfers to real-world focus when practiced 15–30 minutes per day for several weeks. Even without transfer, the tests themselves are diagnostic — tracking your RT variability over time catches attention slumps before you notice them yourself.

What improves when you train this

Ignore more noise

A lower flanker effect means you filter distractions in open offices, phones, and meetings more easily.

Hold focus longer

Vigilance drills directly reduce the late-session mind-wandering that kills productivity.

Stop impulses faster

Go/no-go training strengthens the motor inhibition that prevents reflexive clicks, comments, and decisions.

Catch your own drift

RT variability is a live indicator. Track it and you spot fatigue before a mistake.

How to train this area effectively

  1. Build a daily habit: Attention doesn't build from one heroic session. It builds from many short ones.
  2. Mix the four paradigms: Stroop, flanker, go/no-go, SART each train a different angle. Rotate between them.
  3. Track variance, not just mean: Your average RT matters less than how consistent it is. Steady is the real goal.
  4. Run SART when fresh: Sustained attention tasks punish fatigue. Do them early in the day.

Frequently asked questions

Which test best reflects real-world focus?

SART (sustained attention) is the closest analog to knowledge-work focus. Flanker is closest to filtering distractions.

Why do I get worse as the session goes on?

That's the vigilance decrement — universal and trainable. Each session is a rep.

Is Stroop just a brain game?

No. The Stroop effect has been studied since 1935 and remains a reliable measure of cognitive control across clinical and cognitive neuroscience research.

Should I train caffeinated?

For personal-best hunts, yes. For baseline tracking, stay consistent — always caffeinated, or never.
