Construct and predictive validities of the Perceptual Ability Test.

The construct and predictive validities of the Perceptual Ability Test (PAT) were examined. The results indicate that the PAT is a multidimensional test of spatial abilities, with each of the PAT subtests exhibiting different predictive validity. Furthermore, a linear combination of the PAT subtest scores was found to be more predictive of first-year dental school technique performance than the total PAT score.
