Knox Cube Test

The Knox Cube Test is a test that measures short-term memory and attention span. It was originally developed by Dr. Howard Knox in 1913 as a measure of intelligence. The test consists of four black cubes arranged in a row. A fifth, smaller cube is used to tap a pattern on the cubes, which the respond is then expected to imitate.

For example, the test administrator taps each cube in order from left to right (1st cube, 2nd cube, 3rd cube, 4th cube). The subject is then expected to copy the same sequence. A four-year old child is expected to be able to copy that pattern. The pattern 1, 2, 3, 4, 3 is expected of a five-year old, and so on.

This test is said to be useful in identifying neurological disorders like Attention Deficit Disorder.
