摘要

In the usability testing of Web sites, thinking aloud is anfrequently-used method. A fundamental discussion, however, about thenrelation between the use of different variants of thinking aloud and thenevaluation goals for this specific medium is still lacking. To lay anfoundation for this discussion, I analyzed the results of threenusability studies in which different thinking-aloud tasks were used: ansimple searching task, an application task and a prediction task. In thentask setting, the profile of the Web surfer, the communication goal ofnthe Web site and other quality aspects are taken into account. Thenqualitative analysis of these studies shows that the task variation hasnsome influence on the results of usability testing and that,nconsequently, tasks should be matched with the evaluation goals putnforward
