The Purdue Spatial Visualization Test-Visualization of Rotations (PSVT:R) is a test of spatial visualization ability published by Roland B. Guay in 1977.[1] Many modifications of the test exist.
The test consists of thirty questions of increasing difficulty, the standard time limit is 20 minutes.[2]
Like most measures of spatial ability, the PSVT:R shows sex differences. A meta-analysis of 40 studies found a Hedges's g of 0.57 in favor of males.[3]
