James, K., Lynk, L., Molinari, D. and Caird, J. K. (1995): The Comprehension and Use of Word-Processing Icons. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. p. 941.

“A two-phase study examined the degree that different levels of users understood and actually used word processing icons. In the first phase, 30 novice participants were given 2 questionnaires in which they were asked to generate the meanings of 25 icons and then match pictures of icons to a list of functions. Results indicated that 12 icons passed the International Standards Organization level of icon comprehensibility (67%), whereas only 5 passed the more stringent American National Standard Institute criteria (85%). In phase II, 7 highly experienced users performed a set of 12 useability tasks. These tasks were constructed from the 6 best and 6 worst icons in phase I. The questionnaires from phase I were then given to the experienced users. No difference in performance between the novice and experienced users was found on the questionnaires. In the useability tasks, the experienced users generally choose key and menu command options over icons to execute the tasks. These results have been interpreted to be due to the ambiguity, poor discriminability, size, and/or complexity of the icon. Further discussions center on icon comprehension standards, icon design guidelines, and the heuristic use of icons, menus, and keystroke commands as users acquire application competency. Recommendations are made on the future design and use of icons in word processing packages.”
