A simple test of multiple serial response is proposed which makes use of materials that are inexpensive and easily prepared, and that do not get out of order. The test employs twenty-four colored blocks placed in two rows on a table. The total equipment needed consists of the blocks and a watch.
* To aid the examiner, it is well to have the color of the bottom (with black circle where indicated) together with a number indicating the order in which the block will be picked up. This order is indicated in the first column of Table 2. This information can be marked on a small white label and pasted on the edge of the block away from the subject.
If the subject makes an error, say “Stop: what block do you pick up after—?” (naming the color on the bottom); or “What block do you pick up after— with a black ring?“
