Three forms (hardcopy, positive-image microfiche, and negative-image microfiche) of 12 psychometric instruments employing technical training materials were developed for this study. Ninety Air Force trainees were randomly assigned to one of three experimental groups (hardcopy, positive-image, or negative-image), and their performances were compared. The purposes of this study were 1) to replicate an experiment of Baldwin and Bailey's (1971) in order to see if their results could be reproduced in a different user environment, and 2) to establish the reliability of instruments which Baldwin and Bailey developed as tools for use in future microfiche evaluation. In general, the previous results were replicated. No significant difference in performance among any of the presentation modes was found. No significant difference in performance across all instruments for the positive versus the negative fiche was found. Some variation in performance on individual tests was found in both studies. Use of microform affected subjects' speed but not their accuracy. (Author/JK)
