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 f...

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....

The purpose of this paper was to identify an effective user-requirements data analysis method for informing the design of a Chemical, Biological, Radiological, Nuclear, and Explosive (CBRNE) management decision support system. Data were collected from a large simulation involving medical, police, hazmat/firefighters and subjected to three different...

When an adverse event escalates into a criminal investigation, it becomes very difficult to control and combine information into a manageable format. The PROBE project addresses this problem by developing two generations of working prototypes capable of undergoing live field tests and evaluation by a wide-ranging community of CBRNE (Chemical, Biolo...

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 500 ms each. The second study replicated the first, but participants also rated each web page on seven specific design dimensions. Visual appeal was...

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 satisf...

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 satisfac...

Two studies exploring potential cultural difference in taste are presented in which visual appeal is rated for a set of North American and Taiwanese/Chinese web pages each seen for either 500-or 50 milliseconds. Study 1 confirmed the universality of the mere exposure effect, reflecting a physiologically-based more or less intense feeling of pleasur...
