What is flash word recognition?

Flash word recognition tests your brain's ability to process written words under severe time constraints. Words are displayed for just milliseconds, challenging your visual system to extract letter patterns before they disappear. This measures the speed and efficiency of your early visual word processing, independent of higher-level comprehension.

How to use this test:

Why the masking?

The #### symbols that appear after the word serve an important purpose: they prevent your visual system from continuing to process the afterimage. Without masking, you could "cheat" by using the lingering visual trace. The mask forces you to extract the word identity during the brief presentation, making this a true test of rapid visual processing.

Difficulty levels explained:

These two dimensions are independent - you can combine any flash duration with any answer difficulty for a customized challenge level.
