initial meeting. This design was used to control individual differences
in cognitive ability. Two days after the initial meeting, participants were
informed of their group assignment and its condition and reminded that,
if they were in a food-deprived group, they should not eat anything after
10 a.m. the next day. Participants from the control group were tested at
7:30 p.m. in a designated computer lab on the day the deprivation started.
Those in the 12-hour group were tested at 10 p.m. on that same day.
Those in the 24-hour group were tested at 10:40 a.m. on the following day.
At their assigned time, participants arrived at a computer lab

test. Immediately after all participants had completed the test and their
scores were recorded, participants were each given the silhouette puzzle
and instructed how to proceed. In addition, they were told that (1) they
would have an unlimited amount of time to complete the task, and (2)
they were not to tell any other participant whether they had completed
the puzzle or simply given up. This procedure was followed to prevent
the group influence of some participants seeing others give up. Any
participant still working on the puzzle after 40 minutes was stopped to
keep the time of the study manageable. Immediately after each participant
stopped working on the puzzle, he/she gave demographic information
and completed a few manipulation-check items. We then debriefed and
dismissed each participant outside of the lab.
