EFFECTS OF EXPERIENCE ON LEARNING, USING, AND EVALUATING A TEXT EDITOR.

Routine users of a text editor at a research lab were surveyed about their experiences in learning and using the editor and were asked to describe their likes, dislikes, and suggestions for additions to the system. The 121 users responding to the survey represented samples from three user classes - secretaries, nonprogrammer research members, and programmers - and they varied considerably in their experience both with the editor in question and with other text editors. Experience with the system itself predicted a number of survey measures, such as the customization of programmable function keys, the extension of the editor through macros, and the number and type of additions suggested. However, strong effects of both work type and prior experience with other editors were observed, even for users who were very experienced with the system.
