A general method for identifying the separate components of the Rod-and-Frame Test consists of correlating theoretical patterns of scores with obtained test scores of single subjects. The correlation test calculates probability values from the test data. In this way, fit can be determined between theoretical pattern and test scores. (Author/BW)

Adults took the Rod and Frame, Portable Rod and Frame, and Embedded Figures Tests. Absolute and algebraic frame-effect scores were more reliable and valid than rod-effect algebraic scores. Correlations with the Embedded Figures Test were so low that the interchangeability of these field articulation measures is questionable. (Author/RD)

Three experiments were performed in which subjects were exposed to two sizes of the Embedded Figures Test (EFT), and subjects in the third experiment were also exposed to two sizes of the Rod and Frame Test (RFT). In the first experiment, where the EFT had a size differential of 1 to 4, a nonsignificant size effect and a significant rank…

This study examined the construct validity of the Rod and Frame Test (RFT). Subjects were 554 clients (269 males and 285 females) (aged 14 to 65 years) of the Johnson O'Connor Research Foundation (JOCRF), a vocational guidance service. In a battery of diverse ability and style tests (19 tests of the JOCRF battery and 4 tests of cognitive style),…
