The Use of Iambic Pentameter in the

participants, randomly with replace. For both Experiments 2A and 2B separately, a
repeated measures ANOVA was used to compare reaction times for the global and local
conditions.
In Experiment 3, I compared size scale (global and local) of grouping in a test
period that immediately followed a global or local training session. Participants were
randomly assigned to one condition.
Stimuli
Each experiment used the same types of stimuli. Primes and target stimuli were
created with Power Point, a presentation program. Ready signals and masks were created
with Adobe Photoshop, a digital imaging program. Stimuli were saved with an 8-bit pixel
depth. Stimuli were 640 pixel width by 480 pixel height and displayed in the center of the
screen. Stimuli were displayed on a Macintosh G3 PowerBook. A ready signal preceded
the control, experimental and practice stimuli. A mask immediately then followed each
stimulus after it had been presented. In Experiment 1, a target followed the mask.
Ready signal. The ready signal consisted of a white screen with a black plus sign
in the center. The ready signal prompted the participants to focus their attention on the
fixation cross where stimuli subsequently appeared.
Primes. In the experimental primes, a central pushbutton was depicted with one
pushbutton to its right and one pushbutton to its left (e.g., Figure 22A). The central
pushbutton grouped with the pushbutton on one side by a global Gestalt grouping
property and with the pushbutton on the opposing side by a local Gestalt grouping
