An extension of Guttman’s structural model of ability
tests was devised and investigated with two samples
consisting, respectively, of 335 and 225 males.
The examinees in the first sample came for vocational
guidance after their military service and were administered
a 17-test battery. The second sample consisted of
applicants for various jobs in an organization and were
administered a 14-test battery. For each sample, a matrix
of intercorrelations between scores was obtained
based on the number of correct responses. The matrices
were submitted to Guttman-Lingoes Smallest
Space Analysis. The two-dimensional structure found
was a radex in which (1) the facet of the language of
presentation radially divided the space and (2) the
facet of mental operation formed concentric rings. The
significance of these findings for theoretical and applied
problems relating to ability tests is discussed.
