Visual span tests have been frequently used to assess non-verbal short-term memory. CATs Visual Span provides you with a flexible package for designing tests of visual spatial memory. You can create your own unique tests or variations on previously reported versions of the visual span test. For example in the Corsis Block-Tapping Test the examiner places nine blocks on a board and taps them in a designated sequence. The participant is required to repeat the sequence. Over trials the length of the sequence is increased (see Milner, 1971). The Knox Cube Imitation Test uses four blocks and essentially follows the same logic. The Wechsler Memory Scale - Revised includes a two part visual memory span test. In this test the examiner points at boxes on a eight box card in a prearranged sequence and the subject is required to repeat back the sequence. The initial trial starts with a sequence of two blocks and increases over trials. The two parts of this test are a forward visual span test and a reverse visual span test. Tests similar to these and more can be setup with the CATs Visual Span.
