Press SPACE whenever you see a blue square. Train until your responses become automatic, then pay attention to how the experience changes.
This demonstrates that conscious awareness isn't necessary for behavioral responses. At first, you'll consciously see the blue square, recognize it, then decide to press space.
With practice, the response becomes automatic. You'll find yourself pressing the key before you're consciously aware of what you saw. Your finger "knows" before "you" do.
Phases advance automatically as you complete trials. Just keep going!
Phase 1 (Learning): Shapes appear for 300ms. Get comfortable with the task. (20 trials)
Phase 2 (Speed): Duration drops to 150ms. You must respond faster. (20 more trials)
Phase 3 (Automatic): Duration at 80ms. Conscious recognition becomes difficult —
but your trained response persists.
Pay attention to the feeling of your responses. Early on, there's a clear sequence: see → recognize → decide → press. Later, it becomes: press → "wait, what did I just see?"
