The Visual Patterns Test (VPT) is a measure of short term visual memory that has been designed for use both as a clinical tool and a research instrument. Commonly used measures of non-verbal short term memory are loaded with a spatial component. A good example is the Corsi Blocks Test, which requires the subject to tap specified blocks in sequence. In the VPT, the subject is presented with matrix patterns of black and white squares in grids of varying size and required to memorise a series of black and white checkerboard-like patterns of increasing complexity. Such matrix patterns are virtually impossible to code verbally; moreover, in contrast to the Corsi Blocks Test, no sequencing is required. The VPT is therefore regarded as a purer test of visual memory than the Corsi Blocks Test.

Since the VPT disentangles, in patients as well as healthy subjects, visual storage from other aspects of short term memory, it has great potential for use in studies of attention, mental imagery, and memory. In the neuropsychological setting, it allows comparison of patient groups with different aetiologies, and affords a sensitive measure for use in single case research.

Statistical analysis of data from an age-stratified sample of 363 healthy subjects yielded norms for performance on the VPT, and showed robust associations of VPT with years of education and chronological age. The VPT has high test-retest and equivalent forms reliability, which have been demonstrated both in the standardisation sample and in brain-lesioned patients. The VPT yields a single score, corrected for age and number of years of education and has two parallel forms. Relatively low correlations between the VPT and the Corsi Blocks Test in healthy subjects and in brain-lesioned patients confirm that the two tests are not tapping the same processes.
