The Use of Iambic Pentameter in the

Experiment 2A and 2B
In user interface design, it is important to know more than which types of
information users perceive first. In particular, user interface designers should know what
information can help perform tasks more rapidly. Understanding what information users
can utilize most rapidly can also shed light on what information is processed first. Which
are more rapidly processed and utilized, global or local Gestalt principles of grouping?
To speak to this question, Experiment 2 was conducted.
Method
Experiment 2 actually included two very similar experiments. In both experiments,
unambiguous pushbutton targets were presented to participants for unlimited exposure
durations. Common region and connectedness were each depicted as being relatively
global in some conditions and local in other conditions. In Experiment 2A, I manipulated
grouping scale (global versus local) common region. Examples of these stimuli are
shown in Figure 28A and 28B. The common region in Figure 28A is twice as large in
height as that in Figure 28B. Hence, Figure 28A represents global common region when
compared to Figure 28B. In Experiment 2B, I manipulated grouping scale (global versus
local) with connectedness. Examples of these stimuli are shown in Figure 28C and D.
Connectedness in Figure 28C is four times as high than it is in Figure 28D. Figure 28C
therefore represents global connectedness when compared to Figure 28D because it is
larger in size scale.
