How different does a given pair of circles look?

0 (no difference)
1
2
3
4
5
6
7
8
9 (very different)
  • DONE! You have rated all the pairs.
  • Now, take a moment and look at all your ratings together. ADJUST them so that the most similar, but not identical, circle pair(s) gets the value of 1 and the most dissimilar pair(s) gets the highest value 9.
  • You can change a given rating by clicking on the corresponding cell.
  • When you are satisfied with the results, continue to the final step of the study.

How different does the square pair look to you?

Enter your rating as a number between 0 and 9 by clicking the corresponding radio button or by typing the number directly on the keyboard.
  • A rating of 0 means there is NO DIFFERENCE between the two squares (THE SAME).
  • 1 means the two squares look VERY SIMILAR.
  • 9 means that the two squares look VERY DIFFERENT (for example, 9 times as different as a very similar square pair).
  • Any rating between 1 and 9 should reflect the degree of visual difference between the squares.
