Knox's Cube Test-Revised (KCT-R), published by Stoelting, is a nonverbal test which measures the attention span and short-term memory of children and adults. Because attention span and memory are basic to acquiring almost all other skills, the KCT-R is useful in a wide variety of psychological and educational evaluations.

Directions for the KCT-R are few, and pantomime can be used for administration, making the KCT-R useful in evaluating the mental status of the deaf, non-verbal and foreign-speaking.

The KCT-R Kit includes a Manual, Tapping Cubes and 15 Test/Record Booklets.
