CARD ROTATION TEST

This is a test of your ability to see differences in figures. Look at the 5 triangle-shaped cards drawn below:

These drawings are all of the same card, which has been slid around into different positions on the page.

Now look at the 2 cards below:

These two cards are not alike. The first cannot
be made to look like the second by sliding it
around on the page. It would have to be flipped
over
or made differently.

Each problem in this test consists of one card on the left of a vertical line and eight cards on the right. You are to decide whether each of the eights cards on the right is the same as or different from the card at the left. Click the button beside the S if it is the same as the one at the beginning of the row. Click the button beside the D if it is different from the one at the beginning of the row.

 

Practice on the following rows. The first row has been correctly marked for you.

Your score on this test will be the number of items answered correctly minus the number answered incorrectly. Therefore, it will not be to you advantage to guess, unless you have some idea whether the card is the same or different. Work as quickly as you can without sacrificing accuracy.

You will have 3 minutes for each of the two parts of this test. Each part has 1 page. When you have finished part 1, STOP. Please do not go on to Part 2 until you are asked to do so.

 

DO NOT PROCEED UNTIL ASKED TO DO SO
