⚡ Quick Start

➤ Press Space to begin, then watch the dots move across the screen

➤ Identify the main direction most dots are moving: use ↑↓←→ or WASD

➤ Coherence = signal strength (higher % = easier to see the pattern)

➤ Auto mode adjusts difficulty based on your accuracy

➤ Press Space anytime to pause/resume

Detailed instructions (click to expand)

Press Space or click the blue area to begin.
Watch the moving dots - most move in one direction (signal), others move randomly (noise).
Coherence is the percentage of dots moving together (higher = easier).
Respond with Arrow keys or WASD as quickly as possible.
Auto mode adjusts difficulty based on performance.
Press Space to pause/resume at any time.
Trains dynamic visual acuity for sports, driving, and visual processing.

What Is the Motion Direction Test?

The Motion Direction Test measures dynamic visual acuity and motion perception by asking you to identify the global direction of moving dots (up, down, left, right) embedded in noise. By adjusting coherence (signal strength), the task scales from easy to challenging, providing a quick, browser-based read on selective attention, visual processing speed, and decision accuracy suitable for athletes, gamers, and cognitive training users.

How to Use It and Interpret Your Results

Press Space to start or pause, and answer with the arrow keys or WASD. With auto coherence enabled, difficulty adapts to your performance, converging toward your personal threshold. After each session you will see overall accuracy, direction-specific accuracy, and average reaction times. For practice, track reaction-time stability; for assessment, balance speed and accuracy, and compare sessions over time to spot trends or fatigue effects.

Where It Fits in Cognitive Train and What’s Next

Within Cognitive Train, this test complements attention, working-memory, and task-switching tools as a fast pre-post check or warm-up. Use direction-level metrics to identify asymmetric sensitivities, and log multiple sessions to monitor progress. In future updates, this section will link to articles explaining coherence paradigms, result interpretation, and training protocols to improve motion perception and on-field or in-game performance.
