We are going to show you some rectangles of different areas, and you should type in your best estimate of their area.
Consider the rectangle below: let's call its area 10.
Study this rectangle for a moment. Remember its area!
You will be shown a sequence of other rectangles and should judge their areas based on this one. If a rectangle has twice the square area of this one, answer 20. If it has half the square area, answer 5. Fractional responses are allowed.
Please type in the answer as quickly as you can. For each task you can hit the enter key when you are done (this will be faster than clicking the Submit button).
Don't worry too much about being consistent or trying to remember what you assigned a rectangle before; just judge each one as it comes along. That said, very slow or wildly incorrect answers may result in a rejected HIT.
Please scroll the page as needed to ensure that the full frame is in view.
When you are ready to start, click within the frame and press the space bar to start the timer and begin the tasks.
