The purpose of this study was to determine whether a modified Strauss-Lehtinen Tactual-Motor Test, a gradated version of the Rubin Vase-Face Reversible Figure, Archimedes Spiral Aftereffect Apparatus, and the Necker Cube discriminates between exogenous mental defectives and familial mental defectives. The performance of the exogenous mental defectives and the familial mental defectives on these tests may be useful in describing the perceptual processes of the two groups. The survey of literature revealed little research on the behavior of mental defectives on perceptual tasks.
