Remember Shapes!

This experiment is about your ability to remember the exact shape of an object you see. A shape will briefly appear in the middle of the page; after it disappears, two similar shapes will show up. Your job is simply to select which one matches the first version you saw. Once you're satisfied with your judgment, click "Next Trial".

When you're ready to begin, click "Start Experiment". By completing this experiment, you are consenting to be in this research study. Your participation is voluntary and you can stop at any time.

(NOTE: Please stay focused during the test. The whole process is usually about 5 minutes.)

(NOTE: This is a 'demo' version of the study for the benefit of readers, and does not collect any data; feel free to explore it!)

Select which one perfectly matched the shape you just saw.
