Numerical Stroop

Pick the Highest Value!

You will see two numbers presented side by side, sometimes in different font sizes.
Your task is to select the highest value, ignoring the font size, using the left and right arrow keys.
To see the next set of numbers, press the space bar.
You'll only get one go at each pair, and your decision is final, so try to be as accurate as possible!

Before taking part, please provide your age and gender (if you are comfortable to do so), and enter how many runs of the items you'd like to see. For each run, you'll see 6 items.
