The Use of Iambic Pentameter in the

human interactions with these types of displays could be enhanced by an understanding
of human perception of global and local Gestalt groupings.
Finally, it is important to note that the reported experiments have served to detail
the effect of one task factor, processing time, on global and local perceptual grouping.
However, there may very well be influences of other task factors, like attention and
distractions. These task factors should also be carefully considered within the context of
user interface displays.
Overall summary
Across a series of experiments, the nature of global and local perceptual grouping
was examined within the context of user interface displays. Three pilot studies revealed
that global grouping was more salient in short stimulus durations when compared to
longer stimulus durations. The reported dissertation experiments showed that global
grouping was more salient overall and more usable for speeded tasks.
The reported results contribute to our understanding of how to better design user
interface displays. The application these findings to user interface design may enhance
our ability to perceive and comprehend information presented on computerized displays.
This application may improve our accuracy in working with computerized systems,
therefore increasing the speed in which we perform computer related tasks. Further, the
application these results may increase productivity in many types of work environments
that rely on computers and ease interactions with computerized devices used for personal
activities, such as cell phones and PDAs. The reported results also are important within
