🎯 Flanker Task

⚠️ Keyboard Required: This test uses Z/V keys or arrow keys (←/→)
⚠️ Practice mode results are NOT recorded. In real test mode, arrow positions change randomly to properly test cognitive control.

⚡ Quick Start

You'll see 7 arrows appear on screen. Your task is to identify the direction of the center arrow while ignoring the surrounding arrows.
Press Z or if the center arrow points left. Press V or if the center arrow points right.
Sometimes all arrows point the same direction (congruent trials). Other times, surrounding arrows point the opposite direction (incongruent trials) to test your ability to suppress interference.

Detailed Instructions
⚠️ Keyboard Required: This test uses Z/V keys or arrow keys (←/→)
  1. Click/tap the test area to begin.
  2. You'll see 7 arrows: ←←←←←←← or →→→→→→→ or mixed patterns.
  3. Your task: Respond only to the center (middle) arrow direction.
  4. Press Z or ← (left arrow key) if the center arrow points left (←).
  5. Press V or → (right arrow key) if the center arrow points right (→).
  6. Ignore the surrounding arrows! They are distractors designed to test your focus.
  7. Congruent trials: All arrows point the same way (easier): ←←←←←←←
  8. Incongruent trials: Side arrows point opposite to the center (harder): →→→←→→→
  9. Press Esc or Space to pause/resume at any time.
  10. The test measures sustained attention, interference control, and the Flanker Effect (RT difference between congruent and incongruent trials).
  11. A smaller Flanker Effect indicates better cognitive control and the ability to ignore distractions.
  12. Note: This version uses 70% incongruent trials and 7 arrows for enhanced cognitive challenge.
