What It Tests

Internal time perception — how accurately your brain tracks elapsed time without external cues. Lower deviation means a more reliable internal clock.

How It Works

You'll see four target durations (10, 20, 30, and 45 seconds). For each one, click or press SPACE when you think exactly that much time has passed. Score is the average percentage you were off across all four trials.

Why It Matters

Time perception affects pacing in sports, public speaking, cooking, and how patient you feel during waits. Most people drift 10–25%; trained athletes and musicians often score below 10%.

Tips to Improve

  • 01Don't count out loud or tap your foot — that's a different skill
  • 02Find a comfortable posture and stay still during each trial
  • 03Trust your gut — overthinking usually pulls you further off
  • 04Long durations (30s, 45s) tend to drift more than short ones
