Abstract

Research on the location of usability and user experience tests has shown that testing contexts that include interaction with a tester yield better results. However, the effect of the tester in terms of the amount of interaction has not been directly explored.The goal of this study is to examine the impact of the tester's presence on participant performance and affect on a common usability testing task, a critical incident report. Participants completed two lessons in an intelligent tutoring system and completed a critical incident report for each lesson, either as an interview with a tester or as a survey without a tester present. While tester presence seemed to have almost no impact on performance or affect when directly compared, a number of differences were found with performance and affect when individual difference measures were accounted for. Implications for how user tests can be optimized with these measures are discussed.
