Three studies were conducted to ascertain how quickly people form an opinion about web page visual appeal. In the first study, participants twice rated the visual appeal of web homepages presented for 500ms each. The second study replicated the first, but participants also rated each web page on seven specific design dimensions. Visual appeal was found to(More)
The notion of ‘user satisfaction’ plays a prominent role in HCI, yet it remains evasive. This exploratory study reports three experiments from an ongoing research program. In this program we aim to uncover (1) what user satisfaction is, (2) whether it is primarily determined by user expectations or by the interactive experience, (3) how user satisfaction(More)
Extremely high correlations between repeated judgments of visual appeal of homepages shown for 50 milliseconds have been interpreted as evidence for a mere exposure effect [Lindgaard et al. 2006]. Continuing that work, the present research had two objectives. First, it investigated the relationship between judgments differing in cognitive demands. Second,(More)
Results from a series of web site studies suggest that the concept of user satisfaction comprises more than perceived aesthetics and usability. Satisfaction was repeatedly found to be a complex construct comprising 'emotion', 'likeability', and 'expectation' as well. A web site very high in appeal but low in usability scored highly on user satisfaction when(More)
This study was undertaken to assess the effects of propofol (versus enflurane, fentanyl, and thiopental) on hemodynamic stability and recovery characteristics when used for maintenance of anesthesia during elective coronary artery bypass grafting (CABG) procedures. Ninety premedicated patients scheduled for elective coronary revascularization had anesthesia(More)
We reanalyzed data from three studies to explore first-impression cultural congruency effects and potential rating scale biases among Canadian and Taiwanese/Chinese participants judging visual appeal of homepages. The objective was to identify variables likely to affect such judgments for future studies in a new research program. Some support was found for(More)
