This study investigates whether Iconic Linkage—the use of the identical wording to present the same information recurring in a text—can improve the usability of user guides. Iconic Linkage is a writing strategy that potentially allows users to work more quickly and effectively and which promotes better retention of information. The usefulness of Iconic Linkage was tested in a laboratory-based usability study that combined: 1) objective task-based evaluation; and 2) users' subjective evaluations of a software program used in recording parliamentary debates. A post-test survey designed to test subjects' retention of information contained in the user guides was also administered. The study shows that Iconic Linkage significantly improved usability of the user guide: in all tasks, subjects worked more effectively and made fewer mistakes; while in the three timed tasks, subjects completed the tasks much more quickly. Subjects also gave higher ratings for the software and their retention of information was noticeably improved.
