Spatial
Stroop

An arrow pops up on one side of the screen. Answer the way it points, not where it is. When the two disagree, your brain hesitates for a fraction of a second, and this game measures exactly how long.

Difficulty
Medium · 24 trials
24 arrows. Press the arrow key (or button) for the direction the arrow POINTS. You have 1.5 s for each.
Arrow keys work too.
EXAMPLE ROUND · PLAY TO SEE YOURS

Every response, plotted by speed

Each dot is one trial. Dots further right were slower. The gap between the two average lines is your interference effect: the time your brain spends resolving the clash between where the arrow is and where it points.

ONE IDEA, MANY FORMS

What's clashing in each conflict task?

All of these pit an automatic reaction against the one you've been asked to give. Pick one to see its stimulus and where the conflict comes from.

WHAT THIS GAME TRAINS

Overriding an automatic pull

Where something appears pulls your response automatically. The spatial Stroop makes you answer the direction instead, measuring how quickly you resolve that conflict.

Three places this skill turns up

Each one leans on a different part of what the game trains.

NavigationFollowing directions that conflict with what you see, like mirror images or maps turned around.Uses interference control
Staying on taskSticking to the right response when a distraction pulls you elsewhere.Uses response inhibition
Calm under pressureFast, accurate decisions when information conflicts.Uses processing speed

Acts as the brain's error alarm, noticing conflicts and mistakes so you can adjust. It also helps decide how much effort a task is worth.
ITS JOB IN THIS GAMESpots conflicts and mistakes and signals you to adjustAnterior cingulate detects the clash between position and direction, flagging that extra control is needed.
DID YOU KNOWIts error signal appears in brain recordings within about 100 ms of a wrong response.
