🏀 Bouncing Ball Count Test

What this test measures:

This test trains rapid enumeration under motion — your ability to count moving objects accurately while filtering for a target feature (a specific color). It taps into visual attention, working memory, and dynamic counting skill.

How it works:

1. Press Start Test (or Space) to begin
2. Balls bounce around the screen for the chosen duration
3. In Color Mode, you'll see the target color first — count only balls of that color
4. When the balls disappear, enter your count and press Submit (or Enter)
5. You'll see immediate feedback showing whether your count was correct
6. Complete all trials to see your overall accuracy score

Settings:

• Mode: Count all balls, or count only the target color
• Difficulty: Easy (5–9) / Medium (8–13) / Hard (11–17) / Expert (14–20) balls
• Number of Trials: 5–20 per session
• Speed (Advanced): Slow / Normal / Fast / Super Fast
• Display Duration (Advanced): 3 / 5 / 7 / 10 seconds

Tip: For color mode, focus on the target color and ignore the rest. For higher counts, try grouping balls mentally (e.g., counting in twos or threes).
