A Logical Analysis of Projective Techniques Based on Independence of Items and Latitude of Response
Edwin E. Wagner · Perceptual and Motor Skills · 1995
Projective personality tests can be differentiated from objective personality tests on purely logical and technical grounds. Objective personality tests are derived from and are therefore dependent upon a discrete set of items with an a priori rationale, while projective techniques are superordinate to item construction and any scoring is imposed a posteriori. Further, projective techniques provide more response latitude, although this characteristic lies on a continuum.
