Identify the CENTER arrow's direction! Ignore the flanking arrows and focus on the middle.
How to Play
Five arrows appear in a horizontal row on screen
Press the left or right button matching the center arrow's direction
Ignore the surrounding arrows and focus only on the center
Core Rule: Congruent vs Incongruent
When all arrows point the same way it's easy, but when flankers point the opposite direction they cause interference. Focus on the center only!
Core Rule: Focus on Center
Responding to the flanker arrows instead of the center arrow is incorrect. Keep your gaze fixed on the middle.
Rules
Five arrows appear in a row — judge only the center arrow's direction.
Flanking arrows may point the same way (congruent), opposite (incongruent), or be dashes (neutral).
If you don't respond within the time limit, it counts as incorrect.
Tip
Keep your eyes fixed on the center at all times
Consciously ignoring the surrounding arrows is the key skill
Faster and more accurate responses earn higher scores
The Eriksen Flanker task (1974) is a classic paradigm for measuring selective attention and interference suppression. It is included in the NIH Toolbox and widely used for assessing frontal executive function.
