An Early Set of Kohs Blocks - Early IO Test
American, c.earky 20th Century, label to the front reads 'KOHS BLOCKS, Distributed by The National Foundation for Educational Research 79 Wimpole Street, London W1' each of the 17 cards stamped 'C. H. Stoelting Co, Chicago Ill, U.S.A.' the cards with Roman numerals from I to XVII and 1 marked A, complete with all 16 coloured wooden blocks, in the distressed original card case
Footnote: The Kohs Block test, commonly referred to as the Kohs Block Design Test, is a performance test developed as a measure of IQ. In this test, individuals are required to replicate the patterns shown on a set of test cards using 16 colored cubes. The test was designed with the intention of being accessible to individuals with language or hearing disabilities.
History: The Kohs Block test was developed in 1920 by psychologist Samuel C. Kohs, who was a student of Lewis Terman. It was inspired by previous designs such as Francis N. Maxfield's Color Cube Test. Kohs initially described the test as consisting of 17 cards that increase in complexity. Test takers had to replicate the designs using painted blocks, with each side either a single color or divided by a diagonal line. The original scoring method considered completion time and number of moves, but it was later amended to only score completion time. The test was administered to both children and adults.
In the 1930s, the Kohs Block Test started being given at the Ohio School for the Deaf and other schools catering to students with special needs.
Currently, the Kohs Block Design Test has been incorporated into various IQ tests as separate sections. It is widely used in research to assess executive functioning and learning, consistent with its original purpose. The test has proven useful in studying the effects of aging, drug use, and brain research, among other fields. Its non-verbal nature makes it particularly effective for assessing individuals with language difficulties and in multicultural research settings where language may not be a reliable factor for functional assessment.
Completion of the task in the Kohs Block Test is extremely challenging for patients with right hemisphere brain damage, making it a valuable tool for diagnosing such damage.
