The Use of Iambic Pentameter in the

Participants
General Method
Participants volunteered in exchange for extra credit in undergraduate psychology
courses at the University of South Florida. According to self report, all participants had
normal or corrected-to-normal vision, and all were native English or bilingual speakers
with English as one of their spoken languages. Each volunteer participated in only one of
the experiments. Data from participants who did not meet the above criteria were omitted
from the analysis.
Design
Across experiments, the following remained the same. The size scale of Gestalt
grouping was manipulated as the independent variable. There were two levels for size
scale: global and local. Responses and reaction times were recorded as the dependent
variables. Experimental sessions lasted no longer than 30 minutes.
In Experiment 1, I compared global and local grouping in a 50ms and 4000ms
prime duration. Size scale (global or local) was presented within participants, randomly
with replace. The 50ms and 4000ms prime durations were manipulated between
participants. Participants were randomly assigned to a prime duration (50ms or 4000).
In Experiments 2A and 2B, I compared reaction time for global and local grouping
in unlimited exposure durations. Size scale (global or local) was presented within
70
