A comparative study: edging on the Bender-gestalt test, the Draw-a-person test, and the Memory-for-designs test.

Abstract

A study on the consistency of edging was conducted using three selected dr2~ling tests. Seventy-six college students were administered the Bender-Visual-Motor-Gestalt test, the Draw-A-Person test, and the Memory-For-Designs test. The test administration was purposely designed so that the order of the tests given was rotated from subject to subject. Twenty-eight edgers were found from this initial sample, and it was on these data the analysis was run. The Cochran's Q technique for nominal, dichotimized data was used for analysis in answering the question of a relationship between the three tests and possible consistency of edging performance. Results showed two significant values of Cochran's Q. At an alpha level of .05 with 2 degrees of freedom (interpreted the same as a chi square), both values were greater than the required value of 5.991. Because of these results, the possibility of a significant relationship existing between the three tests and consistency of edging was rejected. While the large majority of edging occurred on the Draw-A-Person test, only a small amount of edging occurred on the Bender-Visual-Motor-Gestalt test and the Memory-For Designs test. Edging was not consistent across all three tests.
