Twin Marks

Find the matching mark

On each card you will see two target symbols in a box on the left, and a search group of five symbols on the right.

Example

Decide whether either target symbol appears in the search group.

  • Choose Yes if one of the targets appears in the search group.
  • Choose No if neither target appears.
  • A symbol only counts as a match if it is identical — rotated or mirrored versions do not count.
  • You have 2 minutes. Work as quickly as you can without making mistakes.

Keyboard: press Y for Yes and N for No.

Twin Marks is an original instructional analogue inspired by the structure of symbol-search style processing-speed tasks. It is not a normed or clinical instrument, and results should not be interpreted diagnostically.
