Readers' preference for process graphics over outcome graphics accompanying assembly instructions

Abstract

We propose that graphics that accompany procedural instructions divide into two categories, namely outcome graphics and process graphics. By using think-aloud protocol, the following questions were asked: 1. Can readers tell the difference between graphical types?; and 2. Do readers prefer one graphical type over another if they are given a choice? With this study we could be able to collect information about what readers want and do not want when they read instructions (n=25). From think-aloud data, 72% of subjects indicated they recognized a difference between outcome graphics and process graphics. Eighty percent of subjects preferred process graphics to outcome graphics. With the study we could also examine subjects' vocalized reasons for their graphical preferences, as well as reading behaviors and vocalized metareading information. Finally, we suggest improvements in the study's method, as well as other ways to continue research that involves outcome graphics and process graphics.
