A block design test is a subtest on many IQ test batteries used as part of assessment of human intelligence. It is thought to tap spatial visualization ability and motor skill . The test-taker uses hand movements to rearrange blocks that have various color patterns on different sides to match a pattern.
Figure 1 from The Block-Design tests by Kohs (1920) showing, in grayscale, an example of his block test. [1] The Kohs Block test, also known as the Kohs Block Design Test, [2] 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.
This is a workable experimental design, but purely from the point of view of statistical accuracy (ignoring any other factors), a better design would be to give each person one regular sole and one new sole, randomly assigning the two types to the left and right shoe of each volunteer. Such a design is called a "randomized complete block design."
Block Design: Put together red-and-white blocks in a pattern according to a displayed model. This is timed, and some of the more difficult puzzles award bonuses for speed. Visual spatial processing and problem solving; visual motor construction Matrix Reasoning
Samuel Calmin Kohs (June 2, 1890 – January 23, 1984) was an American psychologist who spent his career in clinical and educational psychology.He was awarded a B.A. degree at City College of New York, an M.A. at Clark University.
Block Design (primary, FSIQ) – children put together red-and-white blocks in a pattern according to a displayed model. This is timed, and some of the more difficult puzzles award bonuses for speed. Visual Puzzles (primary) – children view a puzzle in a stimulus book and choose from among pieces of which three could construct the puzzle.

The Corsi block-tapping test is a psychological test that assesses visuo-spatial short term working memory. It involves mimicking a researcher as they tap a sequence of up to nine identical spatially separated blocks. The sequence starts out simple, usually using two blocks, but becomes more complex until the subject's performance suffers.
