READY?

READ THE WORD

Press Left Arrow or A for LEFT. Press Right Arrow or D for RIGHT.

Answer the word's meaning, not its screen position. Use ← / A or → / D, or tap a button.

HOW TO PLAY

Read the word and resist the position

  1. 01

    Start the test and watch for LEFT or RIGHT to appear on either side of the stage.

  2. 02

    Answer the word itself. If RIGHT appears on the left, the correct answer is still RIGHT.

  3. 03

    Complete all 20 standard trials, or keep a perfect endless streak as the timer shrinks.

ABOUT THE EFFECT

What is spatial compatibility?

Responses are often easier when a stimulus appears on the same side as its meaning. A conflicting position can interfere even when position is irrelevant.

This game asks you to follow the word while ignoring its location. It is a recreational speed-and-accuracy challenge, not a diagnostic assessment.

READ YOUR RESULT

Balanced compatible and incompatible trials

Standard mode includes exactly five of each combination: each word on the matching side and each word on the conflicting side. Correct answers determine reaction-time statistics.

Input method, screen size, display latency, practice, and attention can affect results. Compare sessions made under similar conditions.

QUESTIONS

Spatial compatibility test FAQ

Should I answer the word or its position?

Always answer the word's meaning. Ignore whether the word appears on the left or right side.

Are standard trials balanced?

Yes. The 20 trials contain five examples of each word-and-position combination, shuffled every run.

What happens after a wrong answer or timeout?

Standard mode records it and continues to the next trial. In endless mode, either event ends the run.

How does endless mode get harder?

The response window begins at 1,800 milliseconds and falls toward 350 milliseconds as your streak grows.

Can I play on a phone?

Yes. Use the two large touch buttons. Keyboard players can use the arrow keys or A and D.

Is this a medical or psychological test?

No. It is an informal browser game and cannot diagnose any medical, neurological, or psychological condition.
