Kohs block design test
The Kohs Block test, also known as the Kohs Block Design Test, is a performance test designed to be an IQ test. The test taker must, using 16 colored cubes, replicate the patterns displayed on a series of test cards. The design of the test was motivated by a belief that the test could easily be administered to persons with language or hearing disabilities.
Kohs described the 1920s version of the test as a series of 17 cards which increase in complexity as the test progressed. Test takers replicated the designs with painted blocks (each side was a single color or two colors divided by a diagonal line). The initial scores were based on completion time and number of moves. Hutt amended the scoring method to only score completion time. The test was given to both children and adults.
The Kohs Block Design Test has been adapted into sections in several current IQ tests. The Kohs test now has little clinical use in its original form.
Patients with damage to the right hemisphere of the brain find successful completion of the task to be extremely difficult, so the test is often used to diagnose right hemisphere damage.
