The Use of Iambic Pentameter in the

Using the previously described type of stimuli, three experiments tested the time
course of global and local grouping in interface displays. Experiment 1 was designed to
test whether global depictions of Gestalt grouping principles are more salient than local
depictions of these principles at short stimulus durations. To address this question,
Hypothesis 1 was proposed.
Hypothesis 1: At short exposure durations, users group elements in ambiguous
interface displays by global Gestalt grouping principles. Conversely, at longer
exposure durations, users can group elements in ambiguous interface displays by
both global and local grouping principles.
Another way to determine which grouping principles are first perceived is to
determine which principles quicken RT. Experiment 2 was designed to test whether
global depictions of Gestalt grouping principles can be grouped significantly faster than
local depictions. To address this question, Hypothesis 2 was proposed.
Hypothesis 2: It is hypothesized that users group interface displays by global
grouping principles at a faster rate than they group by local grouping principles,
when interface displays are presented for unlimited durations.
If the results of Experiments 1 and 2 suggest that particular type of pushbutton
grouping is more salient at short stimulus durations than another, this information might
be used to redesign elemental organizations in user interface displays. How will these
changes be received by users who are familiar with seeing displays with other types of
configurations? Specifically, how does knowledge of what has ‘gone together’ in the past
